Features and benefits of the MFP

Minimum system requirements for e-mail functionality
To use the e-mail functionality, the MFP must be connected to an IP-based network that has a
simple mail transfer protocol (SMTP) server. This server can either be on the local area network or at
an outside Internet service provider (ISP). HP recommends that the MFP be located on the same
local area network (LAN) as the SMTP server. If using an ISP, connect to the ISP by using a digital
subscriber line (DSL) connection. If obtaining e-mail services from an ISP, ask the ISP to provide the
correct SMTP address. Dial-up connections are not supported. If an SMTP server is not on the
network, third-party software is available that allows the creation of an SMTP server. However,
purchase and support of this software is the purchaser's responsibility.

Printing and paper storage environment
Ideally, the printing and paper storage environment should be at or near room temperature, and not
too dry or too humid. Remember that paper is hygroscopic; it absorbs and loses moisture rapidly.
Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while
cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the
humidity from a room. As paper is opened and used, it loses moisture, causing streaks and
smudging. Humid weather or water coolers can cause the humidity to increase in a room. As paper is
opened and used it absorbs any excess moisture, causing light print and dropouts. Also, as paper
loses and gains moisture it can distort. This can cause jams.
As a result, paper storage and handling are as important as the paper-making process itself. Paper
storage environmental conditions directly affect the feed operation.
Care should be taken not to purchase more paper than can be easily used in a short time (about
3 months). Paper stored for long periods might experience heat and moisture extremes, which can
cause damage. Planning is important to prevent damage to a large supply of paper.
Unopened paper in sealed reams can remain stable for several months before use. Opened
packages of paper have more potential for environmental damage, especially if they are not wrapped
with a moisture-proof barrier.
The paper storage environment should be properly maintained to ensure optimum MFP
performance. The required condition is 20° to 24°C (68° to 75°F), with a relative humidity of
45% to 55%. The following guidelines should be helpful when evaluating the paper storage
environment:

●

Paper should be stored at or near room temperature.

●

The air should not be too dry or too humid (due to the hygroscopic properties of paper).

●

The best way to store an opened ream of paper is to rewrap it tightly in its moisture-proof
wrapping. If the MFP environment is subject to extremes, unwrap only the amount of paper to
be used during the day's operation to prevent unwanted moisture changes.

Envelopes
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes
depends upon the quality of the envelopes. When selecting envelopes, consider the following
components:
●

Weight: The weight of the envelope paper should not exceed 105 g/m2 (28 lb) or jamming might
occur.

●

Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 inches) curl,
and should not contain air.

●

Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.

●

Temperature: Use envelopes that are compatible with the heat and pressure of the MFP.

●

Size: Use only envelopes that are within the following size ranges:
●

Minimum: 76 x 127 mm (3 x 5 inches)

●

Maximum: 216 x 356 mm (8.5 x 14 inches)
NOTE Use only tray 1 to print on envelopes. Some jams might occur when using any media
with a length less than 178 mm (7 inches). This might be caused by paper that has been
affected by environmental conditions. For optimum performance, make sure to store and
handle the paper correctly. Select envelopes in the printer driver.

ENWW

Media specifications

Envelopes that have double side seams
Double side-seam construction has vertical seams at both ends of the envelope rather than diagonal
seams. This style might be more likely to wrinkle. Be sure that the seam extends all the way to the
corner of the envelope, as illustrated.

Envelopes that have adhesive strips or flaps
Envelopes that have a peel-off adhesive strip or with more than one flap that folds over to seal must
use adhesives that are compatible with the heat and pressure in the MFP. The extra flaps and strips
might cause wrinkling, creasing, or jams, and might even damage the fuser.

Envelope margins
The following table shows typical address margins for a commercial #10 or DL envelope.
Type of address

Top margin

Left margin

Return address

15 mm (0.6 inches)

Delivery address

51 mm (2 inches)

89 mm (3.5 inches)

NOTE For the best print quality, position margins no closer than 15 mm (0.6 inches) from the
edges of the envelope. Avoid printing over the area where the envelope seams meet.

Envelope storage
Proper storage of envelopes helps contribute to print quality. Envelopes should be stored flat. If air is
trapped in an envelope, creating an air bubble, then the envelope might wrinkle during printing.

Chapter 1

Product information

ENWW

Labels
CAUTION To avoid damaging the MFP, use only labels that are recommended for use in
laser printers. Never print on the same sheet of labels more than once or print on a partial
sheet of labels.

Label construction
When selecting labels, consider the quality of each component:
●

Adhesives: The adhesive material should be stable at 200°C (392°F), the MFP's fusing
temperature.

●

Arrangement: Only use labels that have no exposed backing between them. Labels can peel
off sheets that have spaces between the labels, causing serious jams.

●

Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 inches) of curl in any
direction.

●

Condition: Do not use sheets of labels that have wrinkles, bubbles, or other indications of
separation.
NOTE Select labels in the printer driver.

Transparencies
Transparencies used in the MFP must be able to withstand 200°C (392°F), the MFP's fusing
temperature.
CAUTION To avoid damaging the MFP, use only transparencies recommended for use in
HP LaserJet printers, such as HP-brand transparencies.
NOTE Select transparencies in the printer driver.

Printing on special media
Use these guidelines when printing on special types of media.
NOTE Special media such as envelopes, transparencies, custom-size media, or heavy
media greater than 120 g/m2 should only be used in Tray 1.
To print on any special media, use the following procedure:
1.

Load the media in Tray 1.

When the MFP prompts you for the paper type, select the correct media type for the media
loaded in the tray. For example, select PHOTO GLOSS when loading HP Color LaserJet Glossy
Photo Paper.

In the software application or the printer driver, set the media type to match the media type that
is loaded in the media tray.
NOTE For the best print quality, always verify that the media type selected on the MFP
control panel and the media type selected in the application or printer driver match the type of
media loaded in the tray.

Transparencies
When printing on transparencies, use the following guidelines:
●

Handle transparencies using the edges. Oils from your fingers deposited on the transparency
can cause print quality problems.

●

Use only overhead transparencies recommended for use in this MFP. Hewlett-Packard
recommends using HP Color LaserJet Transparencies. HP products are designed to work
together for optimum printing results.

●

In either the software application or the driver, select TRANSPARENCY as the media type, or
print from a tray that is configured for transparencies.
CAUTION Transparencies not designed for HP Color LaserJet printing might melt in the
printer or wrap around the fuser, causing damage to the MFP.

Glossy paper
●

In either the software application or the driver, select GLOSSY, HEAVY GLOSSY, or
INTERMEDIATE90-104 as the media type, or print from a tray that is configured for glossy paper.

●

Use the control panel to set the media type to GLOSSY for the input tray being used.

●

Because this affects all print jobs, it is important to return the MFP to its original settings once
the job has printed.
NOTE Hewlett-Packard recommends using HP Color LaserJet Glossy Photo Paper and soft
glossy papers designed for use in HP Color LaserJet printers. HP products are designed to
work together for optimum printing results. If other types of glossy media are used, print
quality could be compromised.

ENWW

Printing on special media

Colored paper
●

Colored paper should be of the same high quality as white xerographic paper.

●

Pigments used in colored media must be able to withstand the MFP’s fusing temperature of 190°
C (374°F) for 0.1 second without deterioration.

●

The MFP creates colors by printing patterns of dots, overlaying and varying their spacing to
produce various colors. Varying the shade or color of the paper will affect the shades of the
printed colors.

Envelopes
NOTE Envelopes can be printed only from Tray 1. Set the tray’s media size to the specific
envelope size.
Adhering to the following guidelines will help ensure proper printing on envelopes and help prevent
paper jams:
●

Do not load more than 20 envelopes into Tray 1.

●

The weight rating of envelopes should not exceed 90 g/m2 (24 lb bond).

●

Envelopes should be flat.

●

Do not use envelopes with windows or clasps.

●

Envelopes must not be wrinkled, nicked, or otherwise damaged.

●

Envelopes with peel-off adhesive strips must use adhesives that can withstand the heat and
pressures of the MFP’s fusing process.

●

Envelopes should be loaded face-down and with the postage end feeding into the MFP first.

Labels
NOTE For printing labels, set the tray’s media type to LABELS in the MFP control panel.
When printing labels, use the following guidelines:

●

Verify that the labels’ adhesive material can tolerate temperatures of 190°C (374°F) for
0.1 second.

●

Verify that there is no exposed adhesive material between the labels. Exposed areas can cause
labels to peel off during printing, which can cause paper jams. Exposed adhesive can also
cause damage to MFP components.

●

Do not re-feed a sheet of labels.

●

Verify that the labels lie flat.

●

Do not use labels that are wrinkled, bubbled, or otherwise damaged.

When printing on heavy paper types, use the following guidelines:
●

Use Tray 1 for paper that is heavier than 120 g/m2 (32 lb).

●

For optimum results when printing on heavy paper, use the MFP control panel to set the media
type for the tray to the appropriate paper type listed in Table 1-14 Supported heavy paper types
on page 29.

●

In either the software application or the driver, select the appropriate paper type as the media
type, or print from a tray that is configured for heavy paper.

●

Because this setting affects all print jobs, it is important to return the MFP back to its original
settings once the job has printed.
CAUTION In general, do not use paper that is heavier than the media specification
recommended for this MFP. Doing so can cause misfeeds, paper jams, reduced print quality,
and excessive mechanical wear.

HP LaserJet Tough paper
When printing on HP LaserJet Tough paper, use the following guidelines:
●

Handle HP LaserJet Tough paper only by the edges. Oils from your fingers deposited on
HP LaserJet Tough paper can cause print quality problems.

●

Use only HP LaserJet Tough paper with this MFP. HP products are designed to work together
for optimum printing results.

●

In either the software application or the driver, select TOUGH PAPER as the media type, or
print from a tray that is configured for HP LaserJet Tough paper.

Preprinted forms and letterhead
Observe the following guidelines for best results with preprinted forms and letterhead:

ENWW

●

Forms and letterhead must be printed with heat-resistant inks that will not melt, vaporize, or
release undesirable emissions when subjected to the MFP’s fusing temperature of
approximately 190°C (374°F) for 0.1 second.

●

Inks must be non-flammable and should not adversely affect any printer rollers.

Printing on special media

●

Forms and letterhead should be sealed in a moisture-proof wrapping to prevent changes during
storage.

●

Before loading preprinted paper such as forms and letterhead, verify that the ink on the paper is
dry. During the fusing process, wet ink can come off of preprinted paper.

●

To load pre-printed forms and letterhead into Tray 1, load them face down with the top edge of
the page facing toward you.

●

To load pre-printed forms and letterhead into Tray 2 or an optional tray, load them face up with
the top edge of the page facing away from you.

●

When duplex printing, load pre-printed forms and letterhead into Tray 2 or an optional 500-sheet
tray face down with the top edge of the page towards you.

Recycled paper
This MFP supports the use of recycled paper. Recycled paper must meet the same specifications as
standard paper. Hewlett-Packard recommends that recycled paper contain no more than 5% ground
wood.

Weight equivalence table

Service approach
MFP repair normally begins by using the MFP internal diagnostics and the following three-step
process.
1.

Isolate the problem to the major system (for example, the host computer, the network or server,
or the MFP system).

Determine if the problem is located in the accessories, the scanner assembly, or in the MFP
engine.

Troubleshoot the problem using the procedures in Chapter 7.

After a faulty part is located, the MFP can usually be repaired at the assembly level by replacing field
replaceable units (FRUs). Some mechanical assemblies might need to be repaired at the
subassembly level. Hewlett-Packard does not support replacement of components on the printed
circuit assembles.

CAUTION If paper is loaded in Trays 2 through 4 when the MFP is in Sleep mode, the new
paper will not be sensed when the MFP comes out of Sleep mode. This could cause the
wrong paper to be used for a print job. Be sure to wake the MFP before loading paper in these
trays.
The following detectable standard-sized media is supported in Trays 2 through 4: letter, legal,
executive, A4, A5, and (JIS) B5.
CAUTION Do not print cardstock, envelopes, heavy or extra-heavy paper, or unsupported
sizes of media from the 500-sheet trays. Print on these types of media only from Tray 1. Do
not overfill the input tray or open it while it is in use. Doing so can cause jams in the MFP.

NOTE For best performance, load the tray completely full without splitting or fanning the
ream of paper. Splitting or fanning the ream might cause a multi-feed problem, which
could result in a paper jam. The capacity of the paper tray can vary. For example, if using
75 g/m2 (20 lb) paper, the tray holds a full ream of 500 sheets. If the media is heavier
than 75 g/m2 (20 lb), the tray will not hold a full ream, and the number of sheets must be
reduced accordingly. Do not overfill the tray because the MFP might not pick up the paper.
NOTE If the tray is not properly adjusted, the MFP might display an error message or
the media might jam.
NOTE If duplex printing, place the paper face-down.

Digital faxing is available when installing the optional HP Digital Sending Software. For information
about ordering this software, go to http://www.hp.com/go/digitalsending.
With digital faxing, the MFP does not need to be connected directly to a phone line. Instead, the MFP
can send a fax in one of three ways:
●

LAN fax sends faxes through a third-party fax provider.

●

Microsoft Windows 2000 fax is a fax modem and Digital Sender Module on a computer that
allows the computer to operate as a turnkey gateway fax.

●

Internet fax uses an Internet fax provider to process faxes, and the fax is delivered on a
traditional fax machine or sent to the user’s e-mail.

For complete information about using digital faxing, see the documentation that is provided with the
HP Digital Sending Software.

Embedded Web server
This MFP is equipped with an embedded Web server, which allows access to information about the
MFP and network activities. A Web server provides an environment in which web programs may run,
much in the same way that an operating system, such as Windows, provides an environment for
programs to run on your computer. The output from these programs can then be displayed by a Web
browser, such as Microsoft Internet Explorer or Netscape Navigator.
When a Web server is "embedded", that means it resides on a hardware device (such as a printer) or
in firmware, rather than as software that is loaded on a network server.
The advantage of an embedded Web server is that it provides an interface to the MFP that anyone
can access with a network-connected computer or a standard Web browser. There is no special
software to install or configure. For more information about the HP embedded Web server, see the
Embedded Web Server User Guide. This guide is on the CD-ROM included with the MFP.

Secure Disk Erase
To protect deleted data from unauthorized access on the MFP hard drive, use Secure Disk Erase.
Secure Disk Erase is a security feature that securely erases print and copy jobs from the hard drive.
Secure Disk Erase offers the following levels of disk security:
●

Non-Secure Fast Erase. This is a simple file-table erase function. Access to the file is
removed, but actual data is retained on the disk until it is overwritten by subsequent datastorage operations. This is the fastest mode. Non-Secure Fast Erase is the default erase mode.

●

Secure Fast Erase. Access to the file is removed, and the data is overwritten with a fixed
identical character pattern. This is slower than Non-Secure Fast Erase, but all data is
overwritten. Secure Fast Erase meets the U.S. Department of Defense 5220-22.M requirements
for the clearing of disk media.

●

Secure Sanitizing Erase. This level is similar to the Secure Fast Erase mode. In addition, data
is repetitively overwritten by using an algorithm that prevents any residual data persistence. This
mode will impact performance. Secure Sanitizing Erase meets the U.S. Department of Defense
5220-22.M requirements for the sanitization of disk media.

Data affected
Data affected (covered) by the Secure Disk Erase feature includes stored jobs, proof and hold jobs,
disk-based fonts, disk-based macros (forms), and temporary files that are created during the print
and copying process.

Chapter 3

Installation and configuration

ENWW

NOTE Stored jobs will be securely overwritten only when they have been deleted through
the RETRIEVE JOB menu on the MFP after the appropriate erase mode has been set.
This feature will not impact data that is stored on flash-based product non-volatile RAM (NVRAM)
that is used to store default settings, page counts, and similar data. This feature does not affect data
that is stored on a system RAM disk (if one is used). This feature does not impact data that is stored
on the flash-based system boot RAM.
Changing the Secure Disk Erase mode does not overwrite previous data on the disk, nor does it
immediately perform a full-disk sanitization. Changing the Secure Disk Erase mode changes how the
MFP cleans up temporary data for jobs after the erase mode has been changed.

Gaining access to Secure Disk Erase
Use HP Web Jetadmin to gain access to and set the Secure Disk Erase feature.

Additional Information
For additional information about the HP Secure Disk Erase feature, see the HP support flyer or go to

Job storage features
Several job storage features are available for this MFP. These features include printing private jobs,
storing print jobs, quick-copying jobs, and proofing and holding jobs.
For more information about job storage features, see Job storage features on page 93.

DSS authentication
Optional Digital Sending Software (DSS) for the MFP is available for purchase separately. The
software provides an advanced sending program that contains an authentication process. This
process requires users to type a user identification and a password before they can use any of the
DSS features that require authentication.

Calibrating the scanner
Calibrate the scanner to compensate for offsets in the scanner imaging system (carriage head) for
ADF and flatbed scans. Because of mechanical tolerances, the scanner's carriage head might not
read the position of the image accurately. During the calibration procedure, scanner offset values are
calculated and stored. The offset values are then used when producing scans so that the correct
portion of the document is captured.
Scanner calibration should be carried out only if experiencing offset problems with the scanned
images. The scanner is calibrated before it leaves the factory. It needs to be calibrated again only
rarely.
Before calibrating the scanner, print the calibration target.

Print cartridge storage
Do not remove the print cartridge from its package until you are ready to use it.
Always store the print cartridge in the proper environment. The storage temperature should be
between -20°C and 40°C (-4°F to 104°F). The relative humidity should be between 10% and 90%.
CAUTION To prevent damage to the print cartridge, do not expose it to light for more than a
few minutes.

Print cartridge life expectancy
The life of the print cartridge depends on the amount of toner that print jobs require and the length of
life for the components inside the cartridge. When printing text at approximately 5% coverage (typical
for a business letter), the HP print cartridge lasts an average of 12,000 pages. The page-yield
specification that HP provides is a general guideline. Actual yield can vary according to usage
conditions.
At any time, you can verify life expectancy by checking the supply level, as described below.

ETB life under different circumstances
Depending on the MFP workload, the customer will need to replace the ETB once or twice in the life
of the MFP. In order to help plan supplies purchases, the HP Color LaserJet 4730mfp MFP
calculates an estimated remaining number of pages that can be printed with the ETB.
The number of pages the ETB can print is a function of two factors:
●

The number of times the belt goes from a stationary to a rotating state (spins up)

●

The number of pages that have been printed on the belt

Unless print jobs are queued back to back, each print job requires the belt to spin up.
Think of the ETB as having a limited number of wear units. It has 200,000 wear units when it is new.
Each time the belt spins up, it uses two wear units. Each time it prints a page, the belt uses one wear
unit.
Because most print jobs are not queued, the average number of pages per job, or job length, is a
factor in how fast the ETB will wear out. The shorter the average job, the more quickly the ETB will
wear out.
Figure 4-1 ETB total page count according to average job length on page 115 shows how many pages
an ETB can print, given various average job lengths.

Figure 4-1 ETB total page count according to average job length
The MFP assumes an average print job length of three pages to estimate how many pages are
remaining on the ETB. With an average job length of three pages, the ETB will print 120,000 pages.
If all print jobs are exactly three pages long, for each page printed the number of estimated pages
remaining would decrease by one, beginning with the maximum 120,000 pages. If the job length is
less than three pages, the estimated-pages-remaining number decreases more quickly than the rate
at which the number of pages actually printed increases. If the job length is greater than three pages,
the number of pages remaining decreases less quickly than the rate at which the actual number of
pages printed increases.

MFP memory and fonts
The MFP has 256 MB of synchronous dynamic random-access memory (RAM) expandable to
512 MB by using industry-standard 100-pin double data rate dual inline memory modules (DDR
DIMMS).
NOTE Memory specification: HP Color LaserJet 4730mfp uses 100-pin small outline dual
inline memory modules (SODIMM) that support 128 or 256 MB of RAM.
The MFP also has three flash memory card slots for MFP firmware, fonts, and other solutions.
●

The first flash memory card is reserved for MFP firmware.
NOTE Use the first flash memory card slot for firmware only. The slot is marked
"Firmware Slot".

●

The two additional flash memory card slots enable the user to add fonts and third-party
solutions, such as signatures and personalities. The slots are marked "Slot 2" and "Slot 3”. For
more information about types of solutions available, go to http://www.hp.com/go/gsc.

Configuring and verifying an IP address
Use any of three options to assign and configure TCP/IP addresses on an HP Jetdirect print server:
●

HP Web Jetadmin

●

Embedded Web server

●

Control panel

TCP/IP assignment
The system administrator or primary user is responsible for determining the TCP/IP address for a
specific print server. To confirm the TCP/IP address or to learn how to use TCP/IP on a network, go
to the HP Web site at http://www.hp.com. Click Search in the upper-left corner of the Web page and
search for TCP/IP Overview.

Automatic discovery
The product is equipped with an HP Jetdirect embedded print server. If a BootP or DHCP server is
available during product installation, the print server is automatically assigned an IP address for use
on the network. The print server defaults to 192.0.0.192 (Legacy default) or to 169.254.x.x (Auto IP)
if the print server cannot obtain an IP address over the network from a BootP or DHCP server. The
default that is assigned depends on the particular network (small/private or enterprise) by using
sensing algorithms.
To determine the new IP address, print a configuration page and check the TCP/IP status and
address.

Dynamic host configuration protocol (DHCP)
When the product is turned on, the HP Jetdirect print server broadcasts DHCP requests. The DHCP
automatically downloads an IP address from a network server. The DHCP servers maintain a fixed
set of IP addresses and only loan an IP address to the print server. Consult the operating system
documentation to set up a DHCP service on your network.

Verifying the TCP/IP configuration
Print a configuration page at the product control panel. Check the TCP/IP status and the TCP/
IP addresses. If the information is incorrect, check the hardware connections (cables, hubs, routers,
or switches) and reconfirm the validity of the IP address.

Changing an IP address
Use the following procedures to change the product TCP/IP address.

To change an IP address by using HP Web Jetadmin
Open HP Web Jetadmin. Type the TCP/IP address in the Quick Device Search field and click Go.
At the top menu bar, follow this procedure for discovery options.

Upgrading the firmware
The MFP has remote firmware update (RFU) capability. Use the information in this section to
upgrade the MFP firmware. The overall process involves the following steps:
1.

Determine the current level of firmware that is installed on the MFP.

Go to the HP Web site and find out whether a firmware update is available. If an update is
available, download the latest firmware to the computer.

Transfer the new firmware from the computer to the MFP.

Determining the current level of firmware
To determine the current level of firmware, view the configuration information on the MFP control
panel. To view the configuration information, follow these instructions.
1.

Press Menu.

Touch Information.

Touch PRINT CONFIGURATION. The configuration page prints.

The firmware datecode is listed in the section called Device Information. The firmware
datecode has this format: YYYYMMDD XX.XXX.X. The first string of numbers is the date, where
YYYY represents the year, MM represents the month, and DD represents the date. For
example, a firmware datecode of 20040225 represents February 25, 2004.

Downloading the new firmware from the HP Web site
To find the most recent firmware upgrade for the MFP, go to http://www.hp.com/go/
clj4730mfp_software. This page provides instructions for downloading the new firmware version.

Transferring the new firmware to the MFP
Use one of the following methods to update the firmware.

Using FTP to upload the firmware through a browser
Follow these steps to update the MFP firmware by using FTP through a browser.
To use a browser for firmware update
NOTE These instructions can be used for both Windows and Macintosh operating systems.

ENWW

Print a configuration page and note the TCP/IP address shown on the EIO Jetdirect page.

Open a browser window.

In the address line of the browser, type ftp://, where is the
address of the MFP. For example, if the TCP/IP address is 192.168.0.90, type
ftp://192.168.0.90.

Upgrading the firmware

139

Drag and drop the .RFU file onto the PORT1 icon in the browser window.
NOTE The MFP turns off and then on automatically to activate the update. When the update
process is complete, a Ready message displays on the MFP control panel.

Using FTP to upgrade the firmware on a network connection
NOTE The MFP can receive an .RFU file update as long as it is in a Ready state.
The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes for
the MFP to reinitialize. The I/O transfer time depends on a number of things, including the speed of
the host computer that is sending the update. If the remote firmware update process is interrupted
before the firmware is downloaded (while Receiving upgrade appears on the product control panel
display), the firmware file must be sent again. If power is lost during the flash DIMM update (while the
Performing upgrade message appears on the control panel display), the update is interrupted and
the message Resend upgrade appears (in English only) on the control panel display. In this case,
you must send the upgrade by using the parallel port. Finally, any jobs that are ahead of the RFU job
in the queue are completed before the update is processed.
Follow these instructions to perform the upgrade by using FTP.
NOTE The firmware update involves a change in the format of nonvolatile random-access
memory (NVRAM). Any menu settings that are changed from the default settings might return
to default settings and must be changed again if you want settings that are different from the
defaults.
To upgrade the firmware on a network connection by using FTP

NOTE In the following table, “ETB” stands for “electrostatic transfer/transport belt.”
Table 5-1 Basic operation sequence
Period

Purpose

Remark

WAIT (wait period)

From the time the power
switch is turned on until the
ETB cleaning is completed.

To clear a potential on the
drum surface and to clean
the ETB.

During this period, the MFP
checks the toner level and
detects whether the
cartridges are present. The
MFP also executes the
pulse width modulation
adjustment, color
registration adjustment, and
image density calibration
control as required.

STBY (standby period)

From the end of the WAIT or
LSTR period or last rotation
until the formatter inputs a
print command or until the
power is turned off.

To keep the MFP ready to
print.

When the formatter sends a
Sleep command, the MFP
enters Sleep mode.

INTR (initial rotation period)

From immediately after the
formatter inputs a print
command until the TOP
signal is sent to the formatter.

To stabilize the
photosensitive drum
sensitivity in preparation for
a print operation.

When the formatter sends a
print command in
preparation for printing.

PRINT (print period)

From the end of the INTR
period until the leading edge
detection sensor detects
paper and then turns off the
transfer positive bias.

To form an image on the
photosensitive drum
according to the video signal
input from the formatter and
to transfer the toner image
to the paper.

After the power is turned on,
the cartridge is cleaned
every 35 pages and the ETB
is cleaned every 100 pages.

LSTR (last rotation period)

From the end of the PRINT
period until the drum motor
stops.

To deliver the paper out of
the MFP and to clean the
ETB.

The last rotation period lasts
until the instant the formatter
sends a print command.
Then the initial rotation
period starts again.

Communicating with the host computer through the bidirectional interface

Controlling the Sleep mode

The formatter monitors the MFP continuously through the video interface. When the MFP is ready to
print, the formatter sends a signal to the DC controller, which turns the laser on or off based on the
signal. Figure 5-3 Formatter system on page 150 shows the formatter system.
The formatter also provides the electrical interface and mounting locations for an EIO card, two
memory DIMMs, two additional flash memory cards (a third slot is reserved for firmware), hard disk,
and optional analog fax accessory.

Sleep mode
This feature conserves power after the MFP has been idle for an adjustable length of time. Set the
time length in the Configure Device menu, under SYSTEM SETUP. When the MFP is in Sleep
mode, the product control panel backlight is turned off, but the MFP retains all printer settings,

downloadable fonts, and macros. The default setting is 30 MINUTES. You can turn Sleep mode off in
the Configure Device menu, under RESETS.
The MFP exits Sleep mode and enters the warm-up cycle when any of the following occurs:
●

A print job, valid data, or a PML or PJL command is received at the parallel port, EIO card, or
USB 2.0 connector.

●

A product control panel button is pressed.

●

The right upper and lower covers are opened.

●

The engine test button is pressed.
NOTE MFP error messages override the Sleep mode on message. The MFP enters Sleep
mode at the appropriate time, but the error message continues to appear.

Image Resolution Enhancement technology (REt)
The formatter contains circuitry for Image Resolution Enhancement technology (REt), which modifies
the standard video dot data on its way to the DC controller PCB to produce “smoothed” line edges.
The REt can be turned on or off from the product control panel or from some software programs. The
default setting is medium.
NOTE The REt settings that are sent from software programs or printer drivers override the
control panel settings.

Input/Output
This section explains the MFP input/output (I/O) capabilities.

Parallel interface
The formatter receives incoming data through its bidirectional interface (IEEE-1284). The I/O
provides high-speed and two-way communication between the MFP and the host, allowing the user
to change MFP settings and monitor MFP status from the host computer. The user can configure the
HIGH SPEED item on the control panel menu. (This item is found by navigating to the Configure
Device menu, navigating to the I/O menu, and selecting PARALLEL INPUT.) The default setting,
YES, allows the I/O to run at the higher speeds supported by most newer computers. When set to
NO, the parallel interface runs at the slower mode that is compatible with older computers. The user
can also configure the ADVANCED FUNCTIONS item. The default setting, ON, allows for two-way
parallel communications. The OFF mode disables the advanced functionality. The I/O is compatible
with the bidirectional parallel interface standard.

USB 2.0 connector
The HP Color LaserJet 4730mfp supports a USB 2.0 connector on the back of the MFP. You must
use an A-to-B type USB cable.

ACC accessory port
This MFP also includes a third-party accessory (ACC) port that uses USB host protocol.

ENWW

Formatter system

151

Flash
Optional flash is available in 4 MB flash memory DIMMs for storing forms, fonts, and signatures.

Hard disk
The hard disk is mounted in an EIO slot on the formatter. The hard disk is used to create multiple
original prints (mopies) and store forms, fonts, and signatures.

CPU
The HP LaserJet 4730mfp formatter incorporates a 533 MHz RISC processor.

FIH (foreign interface harness)
The FIH allows connection to third-party devices, such as copy counters and biometric security
devices.

MFP memory
If the MFP encounters difficulty managing available memory, a clearable warning message will
appear on the product control panel.
Some MFP messages are affected by the auto-continue and clearable warning settings from the
Configure Device menu, under SYSTEM SETUP. If Clearable Warning = Job is set on the product
control panel, warning messages appear on the control panel display until the end of the job from
which they were generated. If Clearable Warning = On is set, warning messages appear on the
control panel until is pressed. If an error occurs that prevents printing and Autocontinue = Off is
set, the message appears until Ignore is touched.

Read-only memory
Besides storing microprocessor control programs, the read-only memory (ROM) stores dot patterns
of internal character sets (fonts).

Random-access memory
The random-access memory (RAM) contains the page, I/O buffers, and the font storage area. It
stores printing and font information received from the host system, and can also serve to temporarily
store a full page of print-image data before the data is sent to the print engine. Memory capacity can
be increased by adding DIMMs to the formatter. Note that adding memory (DIMMs) might also
increase the print speed for complex graphics.

DIMM slots
The DIMM slots can be used to add memory, fonts, or firmware upgrades.

Flash memory
To upgrade MFP firmware, upload a new firmware image to the MFP.

152

Chapter 5

Theory of operation

ENWW

Nonvolatile memory
The MFP uses nonvolatile memory (NVRAM) to store I/O and information about the print
environment configuration. The contents of NVRAM are retained when the MFP is turned off or
disconnected.

PJL overview
Printer job language (PJL) is an integral part of configuration, in addition to the standard printer
command language (PCL). With standard cabling, PJL allows the MFP to perform the following
functions:
●

Two-way communication with the host computer through a bidirectional parallel connection. The
MFP can tell the host about such things as the control panel settings, and the control panel
settings can be changed from the host.

●

Dynamic I/O switching allows the MFP to be configured with a host on each I/O. The MFP can
receive data from more than one I/O simultaneously, until the I/O buffer is full. This can occur
even when the MFP is offline.

●

Context-sensitive switching allows the MFP to automatically recognize the personality (PS or
PCL) of each job and configure itself to serve that personality.

●

Isolation of print environment settings from one print job to the next. For example, if a print job is
sent to the MFP in landscape mode, the subsequent print jobs print in landscape only if they are
formatted for landscape printing.

PML
The printer management language (PML) allows remote configuration and status readback through
the I/O ports.

Control panel
The formatter sends and receives MFP status and command data to and from a control panel board.

Scanner interface
The formatter receives data from the scanner to produce copies and to send scanned data in e-mail
format.

Block operation
The blocks that make up the DC controller PCB include:
●

CPU. The CPU is a single-chip microcomputer with built-in ROM and RAM. It controls the MFP
engine sequence, ASIC, fuser, pickup motor and lifter motor, solenoids, sensors, and switches.

●

ASIC. Interfaces with the IC, memory, and external devices.

●

Motor driver ASIC. Controls each motor in response to commands from the CPU.

●

Reset IC. Monitors voltage and resets the CPU and ASIC when the power is turned on.

●

EEPROM. Stores backup data.

Motors, fans, and environment sensor
The MFP has ten motors, ten fans, and one environment sensor. Seven of the motors are DC
motors; the other three are stepping motors. Figure 5-6 Motors and fans on page 157 shows the
locations of the motors and fans. Table 5-2 Function of motors, fans, and environment sensor
on page 157 explains the function of each component.
Two of the stepping motors and six of the seven DC motors are used for paper feeding and image
formation. The remaining stepping motor is the developing disengaging motor. The remaining two
DC motors are fan motors.
Since the MFP transfers an image in four colors in line onto the media, small changes in the
rotational speed of the motor are likely to cause color misalignment. The DC motors used for image
formation are precisely controlled to account for rotational speed fluctuation.

when it encounters the following conditions.
NOTE The drum motor failure detection operates in the same manner for each color
separately.
●

Drum motor start-up abnormality. The interval of the drum motor speed detection signal does
not reach the specified interval after 1.5 seconds of the drum motor drive start.

●

not reach the specified interval after 1.5 seconds of the fuser motor drive start.

●

Fuser motor rotation abnormality. The interval of the fuser motor speed detection signal stays
at an irregular interval for two seconds and longer after it has reached the specified interval.

ETB motor failure detection

it encounters the following conditions.
●

ETB motor start-up abnormality. The interval of the ETB motor speed detection signal does
not reach the specified interval after 1.5 seconds of the ETB motor drive start.

●

ETB motor rotation abnormality. The interval of the ETB motor speed detection signal stays
at an irregular interval for two seconds and longer after it has reached the specified interval.

Rear exhaust fan failure detection
The DC controller detects a rear exhaust fan failure and notifies the formatter of an error status when
the rear exhaust fan lock detection signal is input for ten seconds continuously.

Cartridge fan failure detection
The DC controller detects a cartridge fan failure and notifies the formatter of an error status when the
cartridge fan lock detection signal is input for ten seconds continuously.

Delivery fan failure detection
The DC controller detects a temporary locked status when the delivery fan lock detection signal is
input for 0.5 seconds continuously after 0.1 seconds of delivery fan drive start. The DC controller
starts the drive delivery fan for four seconds at the time of temporary locked status determination. If
the delivery fan lock detection signal is input for four seconds, it detects a delivery fan failure and
notifies the formatter of an error status.

when the power supply fan lock detection signal is input for ten seconds continuously.

Scanner fan failure detection
The DC controller detects a scanner fan failure and notifies the formatter of an error status when the
scanner fan lock detection signal is input.

ADF fan failure detection

ETB fan lock detection signal is input.
Other fan failures can also be detected.

Low-voltage power supply
The low voltage power supply unit generates DC power and controls the fuser. The low voltage
power supply unit consists of the following circuits:
●

Fuser control circuit. Controls the fuser heater temperature in the fuser.

●

Low-voltage power supply circuit. Generates the DC power required in the MFP.

Figure 5-7 Low-voltage power supply circuits on page 161 shows each circuit of the low voltage power
supply unit.

Figure 5-7 Low-voltage power supply circuits

Fuser control circuit
This MFP uses a ceramic heating method to heat the fuser. Figure 5-8 Fuser power supply circuit
on page 161 shows the configuration of the fuser power supply.

Figure 5-8 Fuser power supply circuit

ENWW

Engine control system

161

The fuser power supply system has three main components:
●

Fuser heater. A ceramic heater heats the fuser sleeve. The heater has a U-shaped heating
element on its surface.

●

Thermistors. Two thermistors are in the fuser sleeve: one in the center, and the other at the
end. Each thermistor monitors the temperature in the fuser sleeve.

●

Main thermistor. The main thermistor controls print temperature and between-sheets
temperature. It contacts the inside surface of the fuser sleeve at the center and detects the
fuser sleeve temperature.

●

Sub thermistor. The sub thermistor detects the one-sided temperature rise of the fuser
heater, the initial rotation temperature control, and the start-up temperature control. It
contacts the one side of the fuser heater and detects the fuser heater temperature.

Thermoswitch. The thermoswitch prevents the fuser heater temperature from rising abnormally
high. It is located above the center of the fuser sleeve. If the fuser heater temperature rises
abnormally high, the contact is broken to cut off the power supply to the heater.
These temperature controls are performed by the fuser control circuit and the fuser heater
safety circuit according to the commands from the CPU in the DC controller.

Low-voltage power supply circuit
The low-voltage power supply circuit converts AC power from the wall receptacle into DC power to
cover the DC loads.

Figure 5-9 Low-voltage power supply circuit
The AC power is supplied to the low-voltage power supply circuit by turning on the power switch
(SW101). The AC power is then converted into +24V, +5V and +3.3V to serve the DC power load
requirements.

ENWW

Engine control system

163

Protective functions
Two fuses, FU101 and FU102, protect against overcurrent and overvoltage to prevent failures in the
power supply circuit. If there is a supply error, such as a short-circuit or overvoltage, the low-voltage
system automatically cuts off the output voltage. The fuses blow and cut off the AC power, once AC
overcurrent flows into the AC line.
If DC voltage is not being supplied from the low-voltage power supply circuit, turn off the power
switch (SW101). Do not turn the power on again until the root cause is found. If the cause is not at
the load side, the protective function may still work.
NOTE If the low-voltage power supply is shut down for protection, turn the power off (by
switching off or unplugging the MFP) and leave the MFP off for approximately three minutes.
Then turn the MFP on.
Safety
For safety, the +24V is divided into two: +24VA and +24VB (+24VB1 and +24VB2). The +24VA is
supplied from the DC controller, whereas +24VB stops when the door switch (SW1) is cut off. The
high-voltage power supply PCB and motors are supplied with the +24VB. They stop when the front
cover is opened. This is to protect users and service technicians from injury. The +24VB also
functions as the DOOR OPEN DETECTION signal (DOPEN). The CPU determines that the door is
open when the +24VB supply stops.
Sleep mode
Sleep mode reduces power consumption during periods of inactivity. When the DC controller
receives a Sleep command from the formatter, the controller stops the supply of +24V and +5V
power by operating the power-save circuit. At the same time, it sends a POWER SAVE MODE signal
(PSAVE) to the low-voltage power supply circuit. The low-voltage power supply circuit implements
PSAVE upon receiving the /PSAVE signal. The MFP returns to the WAIT period once it receives a
command from the formatter ending Sleep mode.
Power supply recognition
The low-voltage power supply circuit recognizes the voltage specification (100V or 200V) that the
MFP uses and the CPU switches the temperature control firmware for the fuser accordingly. The
CPU monitors the 100V POWER SUPPLY DETECTION signal (PS100V). When the MFP is
connected to the 100V power source, the temperature control firmware is switched for the 100V
specification. In the same way, when the MFP is connected to the 200V power source, it is switched
for the 200V specification.

Heater temperature control
The heater temperature control detects the surface temperature of the fuser sleeve and controls the
current flowing to the induction heating coil. The heater temperature control circuit is shown in Figure
5-10 Heater temperature control circuit on page 165.

164

Chapter 5

Theory of operation

ENWW

Figure 5-10 Heater temperature control circuit
The fuser heater temperature is monitored by two thermistors: the main thermistor (TH1) and the sub
thermistor (TH2). The main thermistor controls the print temperature and the between-sheets
temperature. The sub thermistor detects the one-sided temperature rise of the fuser heater, and
controls the initial rotation temperature and the start-up temperature.
The CPU (IC1101) on the DC controller monitors the voltage of the fuser heater temperature signals.
The CPU sends the fuser heater drive signal (FSRD1) according to the voltage level. The fuser
heater control circuit controls the fuser temperature so the heater remains at the target temperature.
The fuser temperature control is divided into the following four sequences.
NOTE During standby, the fuser temperature is maintained at about 76.7°C (170°F) to
accommodate a first-print time of less than 15 seconds.

Initial rotation temperature control
This control melts the grease inside the fuser sleeve and lubricates the sleeve when the power is
turned on to prevent sleeve damage. If the sub thermistor detects the temperature of below 50°C
(122°F) at power-on, the CPU turns on the fuser heater for a prescribed time period before it drives
the fuser motor.

Start-up temperature control
This control determines the start-up power provided to the fuser heater according to the temperature
detected by the sub thermistor at heater energization. If the heater is energized within 30 seconds
after the previous print completion, the heater control starts at this temperature point.

ENWW

Engine control system

165

Print temperature control
This control maintains the temperature of the fuser sleeve at its targeted temperature during the
printing operation. The CPU gradually raises the targeted temperature in one printing process. This
prevents the fuser temperature from falling while the media goes through the fuser roller. The
targeted temperature also varies according to the number of prints when continuous printing. The
targeted temperature varies depending on the media types.

Between-sheets temperature control
This control maintains the temperature of the fuser heater below its normally targeted temperature
during continuous printing. This prevents the excessive temperature rise of the fuser pressure roller
while uncovering the paper portion of between-sheets with low-speed mode. The targeted
temperature varies according to the between-sheets intervals and the media types.

Temperature protective function
This function detects an abnormal temperature rise of the fuser and interrupts power supply to the
fuser heater. The following three protective components prevent an abnormal temperature rise of the
fuser heater.
●

CPU

●

Fuser heater safety circuit

●

Thermoswitch

Protective function by the CPU
The CPU always monitors the output voltage of the main and sub thermistors (FSRTH1, FSRTH2). If
the voltage of the FSRTH1 is approximately 0.9V and lower (equivalent to 230°C (446°F) and
higher), or the voltage of the FSRTH2 is approximately 0.46V and higher (equivalent to 285°C (545°
F) and higher), the CPU detects a fuser failure and then performs the following sequence:
1.

The CPU sets the fuser heater drive signal (FSRD1) to inactive and turns the heater off.

The CPU sets the relay drive signal (FSRLD) to stop through the ASIC.

The fuser heater safety circuit sets the main thermistor relay drive signal (RLD-) to inactive.

The fuser heater safety circuit sets the sub thermistor relay drive signal (RLD+) to inactive.

The relay drive circuit releases the relays (RL101 and RL102) to interrupt power supply to the
fuser heater.

Protective function by the fuser heater safety circuit
The fuser heater safety circuit monitors the output voltage of the main and sub thermistors (FSRTH1,
FSRTH2). If the voltage of the FSRTH1 is approximately 0.8V and lower (equivalent to 240°C (464°
F) and higher), or the voltage of the FSRTH2 is approximately 0.41V and higher (equivalent to 293°C
(559°F) and higher), the circuit detects a fuser failure and performs the following sequence:

166

The fuser heater safety circuit makes the main thermistor relay drive signal (RLD-) inactive.

The fuser heater safety circuit makes the sub thermistor relay drive signal (RLD+) inactive.

The relay drive circuit releases the relays (RL101 and RL102) to interrupt power supply to the
fuser heater.

Chapter 5

Theory of operation

ENWW

Protective function by the thermoswitch
When the temperature of the fuser heater rises abnormally high and the detected temperature of the
thermoswitch (TP) exceeds approximately 250°C (482°F), the thermoswitch is disconnected and the
power supply to the fuser heater is immediately cut off.
NOTE The actual temperature of the fuser heater is about 30° higher than the thermoswitch,
as the thermoswitch is not contact with the fuser heater.

Temperature failure detection
The CPU determines the fuser failure, stops the MFP engine, and notifies the formatter of an fuser
failure when it encounters the following conditions:

Start-up failure (warm-up failure)
The CPU determines a start-up failure:
●

If the detected temperature of the main thermistor does not reach 185°C (365°F) within 30
seconds of heater energization during the wait period.

●

If the heater does not enter the Ready mode within 30 seconds of heater energization during
the initial rotation period.

Abnormal low temperature of main thermistor (no conduction)
The CPU presumes the main thermistor has no conduction:
●

If the detected temperature of the main thermistor is kept 40°C (104°F) or lower for four
seconds continuously, from heater energization until the heater is turned off during the wait
period.

●

If the detected temperature of the main thermistor is kept 70°C (158°F) or lower for four
seconds continuously, from initial rotation start until the media reaches the fuser during the
initial rotation period.

●

If the detected temperature of the main thermistor is kept 130°C (266°F) or lower for 0.5
seconds continuously, from when the media reaches the fuser until the heater is turned off
during the print period.

Abnormal high temperature of main thermistor
The CPU presumes an abnormal high temperature of the main thermistor if the detected temperature
of the main thermistor is kept 230°C (446°F) and higher for 0.1 seconds continuously.

Abnormal low temperature of sub thermistor (no conduction)
The CPU presumes the sub thermistor has no conduction:

ENWW

●

If the detected temperature of the sub thermistor is kept 60°C (140°F) or lower for four seconds
continuously, from heater energization until the heater is turned off during the wait period.

●

If the detected temperature of the main thermistor is kept 90°C (194°F) or lower for 2.5 seconds
continuously, from initial rotation start until the media reaches the fuser during the initial rotation
period.

Engine control system

167

●

If the detected temperature of the main thermistor is kept 120°C (248°F) or lower for 0.5
seconds continuously, from when the media reaches the fuser until the heater is turned off
during the print period.

●

If the detected temperature of sub thermistor is kept 50°C (122°F) or lower for 0.5 seconds
continuously during the standby period.

Abnormal high temperature of sub thermistor
The CPU determines the abnormal high temperature of sub thermistor if the detected temperature of
the sub thermistor is kept 285°C (545°F) and higher for 0.1 seconds continuously.

Drive circuit abnormality
The CPU determines the drive circuit abnormality if the ZERO CROSSING signal (ZEROX) is not
detected for the specified time period.

High-voltage power supply
The high-voltage power supply PCB produces the voltage biases that are applied to the primary
charging roller, developing cylinder, developing blade, attraction roller, and transfer roller. There are
two types of biases: DC positive bias and DC negative bias. The high-voltage power supply PCB is
controlled by the DC controller.

Generation of biases
Generation of primary charging bias: The primary charging bias is the DC negative bias that is
generated to apply negative potential to the photosensitive drum in preparation for image formation.
This bias is generated for each color (Y, C, M, K) in the primary charging high-voltage power supply
circuit. The high-voltage power supply PCB applies the primary charging bias (PRI1, PRI2, PRI3,
PRI4) to the primary charging rollers in each cartridge at the specified timing. The value of the
primary charging bias varies in response to commands from the DC controller.
Generation of developing bias: The developing bias is the DC negative bias that is generated to
adhere toner to an electrostatic latent image formed on the photosensitive drum. This bias is
generated for each color. The high-voltage power supply PCB applies the developing biases (DEV1,
DEV2, DEV3, DEV4) to the developing cylinders in each cartridge at the specified timing. The value
of the developing bias varies in response to commands from the DC controller.

ENWW

Engine control system

169

The developing voltage (bias) causes the toner to adhere to the electrostatic image that the laser/
scanner assembly created on the photosensitive drum. Two types of developing biases are used: the
developing DC negative bias and the developing AC bias. The high-voltage circuit on the power
supply generates both biases. These biases are superimposed on one another and then applied to
the primary charging roller, which transfers the biases to the drum. The biased developing cylinder
picks up toner particles and deposits them onto the electrostatic image on the photosensitive drum.
The image is now visible on the drum.
Generation of developing blade bias: The developing blade bias (BL) is the DC negative bias that
is generated to charge the toner. This bias is generated for each color in the developing blade highvoltage power supply circuit in the high-voltage power supply PCB. The high-voltage power supply
PCB applies the developing blade biases (BL1, BL2, BL3, BL4) to the developing blade in each
cartridge at specified timing. The value of the developing blade bias varies in response to the
command from the DC controller.
Generation of attraction bias: The attraction bias is generated to attract paper to the ETB and to
transfer toner onto the paper efficiently. Both DC positive and DC negative biases are generated
when attracting paper and cleaning the ETB. The high-voltage power supply PCB applies the
attraction biases (ATTS) to the attraction roller in the ETB unit at the specified timing. The value of
the attraction bias varies in response to the command from the DC controller. The DC controller
changes the value of the attraction bias and regulates it in constant current control in response to the
ATTRACTION CURRENT VALUE RETURN signal (HVATTS) sent from the high-voltage power
supply PCB. The following are the printing sequences.
●

Attraction charging bias: This bias charges the paper positively or negatively and makes the
negatively charged toner transfer easily.

●

Between-sheets bias: This bias prevents the residual toner on the ETB from adhering to the
attraction roller in the between-sheets during continuous printing.

●

Cleaning bias: This bias prevents the residual toner on the ETB from adhering to the attraction
roller during ETB cleaning.

Generation of transfer bias: The transfer bias is generated to transfer toner onto the paper. Both
DC positive and DC negative biases are generated in the transfer high-voltage power supply circuit
in the high-voltage power supply PCB. The DC positive bias is generated when transferring toner,
and the DC negative bias is generated when cleaning the ETB. The high-voltage power supply PCB
applies the transfer biases (TR1, TR2, TR3, TR4) to the transfer roller in the ETB unit according to
the print sequences. The value of the transfer bias varies in response to the command from the DC
controller. The DC controller changes the value of the transfer bias and regulates it in constant
current control in response to the TRANSFER CURRENT VALUE RETURN signals (HVTR1S,
HVTR4S) and the HVATTS signal sent from the high-voltage power supply PCB. The following are
the printing sequences.

170

●

Print bias: This bias transfers toner on the photosensitive drum surface onto the paper during
printing. The transfer roller is applied with the DC positive bias.

●

Between-sheets bias: This bias prevents the residual toner on the ETB from adhering to the
attraction roller in the between-sheets during continuous printing.

●

Cleaning bias: This bias cleans the ETB by returning any toner remaining on the ETB surface
to the photosensitive drum. The transfer rollers in the yellow and magenta cartridges (first and
third colors) are applied with DC negative bias. The rollers in cyan and black cartridges (second
and fourth colors) are applied with DC positive bias.

Sub power supply assembly
The sub power assembly provides power to the ADF and the image scanner. It is connected to the
low-voltage power supply and the DC controller.

Video interface control
The video interface allows communication between the formatter and the DC controller. The
formatter always monitors the status of the MFP by using the video interface. It sends the VIDEO
signals to the DC controller through the video interface when the MFP is ready to print. The DC
controller turns the laser on or off based on the signals it receives.

Figure 5-12 Video interface control
The VIDEO INTERFACE signal is exchanged during printing operations, as described below.

ENWW

When the MFP engine is ready to print, the DC controller notifies the formatter using the
STATUS COMMAND signal (SC).

The formatter sends a print command as a SC signal to the DC controller when the MFP engine
and the data for one page are ready.

The DC controller drives the scanner motor and sends the HORIZONTAL SYNCHRONOUS
signals to the formatter after receiving the print command.

The printer engine starts a pickup operation. When the paper arrives at the top of page sensor
(SR12), the DC controller sends the VERTICAL SYNCHRONOUS signal (/TOP) to the formatter.

The formatter sends VIDEO signals in synchronization with the HORIZONTAL
SYNCHRONOUS signals to the DC controller upon a reception of the /TOP signal.

The DC controller controls each color’s laser driver circuit and turns the laser on and off
according to the VIDEO signals. This forms an electrostatic latent image on the photosensitive
drums of each color.

Engine control system

171

172

The latent images on the photosensitive drums are developed by toner and transferred onto
paper in this order: Y (yellow), C (cyan), M (magenta), and K (black).

The toner is fused to the paper in the fuser and the paper is delivered to the delivery tray.
Printing continues if the DC controller receives another print command from the formatter during
the printing operation.

Chapter 5

Theory of operation

ENWW

Laser/scanner system
The laser/scanner system forms the latent electrostatic image on the photosensitive drum according
to video signals sent from the formatter. The main components of each laser/scanner assembly are
the laser driver, scanner motor, mirrors, and focusing lenses. Each color has its own laser/scanner
assembly unit, which is controlled by the DC controller.

Figure 5-13 Laser/scanner assembly
The laser/scanner system uses two laser diodes in one scanning operation to write two lines
simultaneously for high-speed laser scanning. The process is summarized below:

ENWW

After receiving the print command from the formatter, the DC controller activates the scanner
motor to rotate the six-faced scanner mirror.

When the scanner motor starts to rotate, the DC controller allows the laser to emit light and
maintains the scanner motor rotation at a constant speed.

When the scanner motor reaches its specified speed, the formatter sends video signals to the
laser driver PCB through the DC controller. The laser driver emits two laser diodes according to
these signals.

The laser beams pass through the collimator lens and the cylindrical lens, and enter the sixfaced mirror that is rotating at a constant speed.

Laser/scanner system

173

The laser beams are reflected by the six-faced mirror, pass through the focusing lens and the
reflecting mirror that is in front of the six-faced mirror, and focus the photosensitive drum.

While the six-faced mirror rotates at a constant speed, the laser beams on the photosensitive
drum scan the drum.

As the photosensitive drum rotates and the laser beams scan on the photosensitive drum, both
at a constant speed, a latent image is formed the drum.

Laser control
The laser control circuit allows the laser driver IC to turn the laser diodes LD1 and LD2 on and off
according to the image data signals sent by the DC controller.
The DC controller sends video signals (VDODAT11, /VDODAT11, VDODAT12, and /VDODAT12)
and laser control signals (LDCTRL10, (LDCTRL11, and (LDCTRL12) to the logic circuit on the laser
driver IC. The laser driver IC controls the laser according to the combination of the laser control
signals.

●

Horizontal synchronous control. Aligns the starting position in the horizontal direction.

●

Image masking control. Regulates laser beam emission in non-image area except during the

The scanner motor control rotates the scanner motor in order to strike the laser beam at the correct
position on the photosensitive drum.

The DC controller divides the oscillation frequency of the oscillator (X1201) and generates the
reference clock signal. It compares the intervals between the reference clock signal and the BD input
signal (/BD1I) with the frequency comparator, and monitors the rotational count of the scanner motor.
The DC controller controls rotational speed by sending an acceleration signal (/SCNACC1) or
deceleration signal (/SCNDEC1) to the scanner motor driver based on the detected rotational speed.
Figure 5-15 Scanner motor circuit diagram on page 176 illustrates the scanner motor control system.

scanner motor and adjusts the phase of the scanner motor.

scanner motor is rotating at its specified rotational count.

Image formation system
The image formation system is the central hub of the MFP. It also forms the toner image on the media.
The image formation system consists of four cartridges, the ETB, and the fuser, which are controlled
by the DC controller. Figure 5-16 Image formation system on page 177 shows the image formation
system.

Figure 5-16 Image formation system

Image formation process
The image formation process consists of nine steps divided among five functional blocks:
1.

Electrostatic latent image formation block. Forms an electrostatic latent image on the
photosensitive drum.
Step 1: Pre-exposure
Step 2: Primary charging
Step 3: Laser beam exposure

Development block. Makes the electrostatic latent image on the photosensitive drum surface
visible by applying toner.
Step 4: Development

Transfer block. Transfers toner image on the photosensitive drum onto the media.
Step 5: Attraction
Step 6: Transfer
NOTE Toner is transferred onto a sheet of media in the order of yellow (Y), cyan (C),
magenta (M), and black (K) in one printing operation.
Step 7: Separation

Step 8: Fusing

Electrostatic latent image formation block
The image formation process begins in the electrostatic latent image formation block. This block
consists of three steps that results in forming an electrostatic latent image on the photosensitive drum:
●

Pre-exposure

●

Primary charging

●

Laser beam exposure

When the last step in this block is complete, areas of the drum surface that have not been exposed
to the laser beam retain a negative charge. The areas that have been exposed to the laser are
neutralized. This neutralized image is called an electrostatic latent image because it is invisible to the
eye.

To prepare for primary charging, light from the pre-exposure LED strikes the photosensitive drum
surface. This eliminates any residual charge on the drum surface to avoid density unevenness.

Chapter 5

Theory of operation

ENWW

Step 2: Primary charging
To prepare for latent image formation, the surface of the photosensitive drum is charged with a
uniform negative potential.
The charging method of this MFP is to charge directly to the photosensitive drum surface from the
primary charging roller, which is interlocked with the drum. The primary charging roller is made of a
conductive rubber. To charge the drum surface negatively, the DC bias is applied to the primary
charging roller.

Step 3: Laser beam exposure
In this step, the latent image is formed on the photosensitive drum by the laser beam. As the laser
beam scans on the negatively charged photosensitive drum, the potential on the exposed area is
neutralized and the negative potential is removed from the drum surface. This area forms an
electrostatic latent image.

Laser beam

Exposed area

Unexposed area

Figure 5-20 Laser beam exposure

Development block
The second part of the image formation process is the development block, where toner is transferred
onto the electrostatic latent image on the surface of the photosensitive drum to create a visible
image. This MFP uses a contact development method that keeps the developing cylinder in contact
with the drum, pushing the toner against the drum surface for development. The toner is nonmagnetic and consists of resins.

Step 4: Development
In this step, the toner adheres to the electrostatic latent image on the photosensitive drum surface.
The toner (developing material) has an insulating property and is charged with a negative potential
by the friction force with the rotating developing cylinder and the developing blade surface. This
negatively charged toner contacts with the photosensitive drum, after the potential is adjusted to be
uniform. As the area of the drum surface where the laser beam exposed has higher potential than
the developing cylinder, the toner charged with almost the same potential with the developing
cylinder adheres to this area. This phenomenon is called contact development and it visualizes the
electrostatic latent image on the drum surface.

ENWW

Image formation system

181

Transfer block
The third part of the image formation process is the transfer block, in which the toner image is
transferred from the photosensitive drum to the media. This block consists of three steps:
●

Attraction

●

Transfer

●

Separation

Step 5: Attraction
To feed the media vertically, it is necessary to push the media against the ETB. The picked up media
is fed as it is pushed against the ETB by the attraction roller. The positive DC bias is applied to the
attraction roller, which charges the media positively to make the negatively charged toner easier to
transfer onto the media during the transfer operation.
ETB

Attraction roller

DC bias

ETB engaged roller

Paper

Figure 5-21 Attaching the media to the ETB

Step 6: Transfer
A positive bias is applied to the transfer charging roller, which is directly opposite the photosensitive
drum. As the ETB passes the transfer charging roller, it picks up a positive charge. The negatively
charged toner on the photosensitive drum is transferred to the positively charged print media. Figure
5-22 Toner transfer on page 183 illustrates this step. This process is repeated for each color as the
ETB carries the media from the bottom cartridge to the top (C, Y, M, K).
In full-color printing, as four colors of toner are piled up on the media, the holding force of the toner
weakens as the transfer process progresses. To counteract this effect, the DC controller increases
the positive DC bias that is applied to the transfer charging roller for each successive color.

Fusing block
The fourth part of the image formation process is the fusing block, in which the toner image is fused
to the media, making a permanent image that cannot be smeared. This block consists of one step:
fusing.

Step 8: Fusing
This MFP uses the ceramic heater with lower heat capacity to fuse the toner to the media. This
method warms up quickly and does not require the power supply during standby period, resulting in
shortened wait time and reduced power consumption.

ENWW

Image formation system

183

Figure 5-24 Fusing

Cleaning block
The fifth and final part of the image formation process is the cleaning block, in which the
photosensitive drums are cleaned, preparing them for the next print. In the transfer block, not all of
the toner is transferred from the photosensitive drum onto the media, but some remains on the drum
surface. This remaining toner is called residual toner or waste toner. The cleaning block cleans the
photosensitive drum surface to keep a clear image in the next print.

Step 9: Drum cleaning
The cleaning blade scrapes off the leftover toner on the drum surface. The residual (waste) toner is
collected in the waste toner container by the waste toner feed plate.

Print cartridges
The MFP has four different print cartridges, one for each color. However, they share the same
structure, shown in Figure 5-25 Print cartridge on page 185.

The DC controller uses an LED and a photo diode to monitor the level of toner inside the cartridge. It
stores this information on a memory tag that is built into each cartridge.

Memory tag
The memory tag is a nonvolatile memory that is built into the print cartridge. It stores information
about the amount of toner in the cartridge and estimates the remaining life. Figure 5-26 Memory tag

The DC controller reads information from the memory tag whenever the MFP is turned on, whenever
the top cover is closed, and whenever it receives a read command from the formatter.
The DC controller writes information to the memory tag at specified times during a print operation,
whenever it receives a write command from the formatter, and after print completion.
If the DC controller is unable to either read to or write from the memory tag four times in a row, the
DC controller alerts the formatter of a memory tag abnormality.

Cartridge presence detection
The MFP detects the presence of print cartridges when the power is turned on or the door is closed.
There are two procedures to the cartridge presence detection:
●

Memory tag detection

●

Photosensitive drum detection

Memory tag detection
The DC controller reads the data in the memory tag and determines the cartridge presence. If the
reading fails, the DC controller goes to the next procedure, photosensitive drum detection.

Photosensitive drum detection
The DC controller measures the torque of the photosensitive drum. The DC controller stops the drum
motor after driving it for the prescribed period of time. If the motor stops rotating within the specified
period after the stoppage command is sent, the DC controller detects the cartridge presence based
on the large load torque. If it takes more than the prescribed period of time for the motor to stop, the
DC controller detects the cartridge absence based on the small load torque.
When the DC controller detects the cartridge absence, it stops the engine and notifies the formatter.
Figure 5-27 Photosensitive drum detection on page 187 illustrates the drum detection procedure.

Developing cylinder disengaging control
The developing cylinder is engaged or disengaged when the DC controller drives the developing
alienation motor. When the developing motor rotates clockwise by a command from the DC controller
during power on, printing operation stopped, cleaning cartridges, and monochrome print, the
developing alienation cam rotates. Accordingly, the rear bottom of the cartridge is raised and the
developing cylinder is disengaged from the photosensitive drum with a principle of leverage. The
developing alienation sensor (SR11) detects the position of the developing alienation block.
NOTE Only the developing cylinders in the color cartridges (C, Y, M) are disengaged in
monochrome print, and all of the developing cylinders in any other case.
If the cam stays at its home position for the prescribed period of time or longer during the developing
cylinder disengagement operation, or it does not return to the home position within the prescribed
period of time after alienation is completed, the DC controller detects the developing alienation motor
abnormality, stops the printer engine, and notifies the formatter of the developing alienation motor
abnormality.

ETB (electrostatic transfer/transport belt)
The ETB feeds the media through the MFP and helps transfer toner onto the media. Figure 5-28 ETB

used for the color misregistration and image stabilization control. The pattern image for the color
misregistration or image density determination is transferred onto the ETB.
The ETB also controls the following:
●

Transfer roller (Y, C, M) engagement/disengagement detection

●

Transfer roller alienation

●

ETB cleaning

Transfer roller (Y, C, M) engagement/disengagement detection
When the power is turned on, the DC controller applies biases to the transfers roller for yellow and
black, and detects the value of current flown through the ETB according to the current return signals.
The DC controller obtains information on the transfer roller (Y, M, C) engagement and
disengagement. Accordingly, the DC controller executes the transfer roller engage or disengage
control depending on the situation and engages the transfer rollers (Y, M, C).

Transfer roller engagement/disengagement control
This control disengages the transfer rollers (Y, M, C) from the photosensitive drums so that only
black toner is transferred onto the ETB during monochrome printing. The ETB motor (M7) performs
this control by driving the ETB alienation solenoid (SL3) while the motor is rotating according to a
command from the DC controller.
The following is the operational sequence of the transfer roller engagement/disengagement control.
1.

The transfer roller engaging/disengaging cam inside the ETB holds up the transfer roller holder
that contains the Y, M, and C transfer rollers. This brings the ETB into contact with the
photosensitive drums.

When a monochrome print starts, the DC controller turns on the ETB alienation solenoid (SL3)
to rotate the transfer roller engaging/disengaging cam.

The rotation of the transfer roller engaging/disengaging cam pushes the Y, M, and C transfer
rollers down, disengaging the ETB from the photosensitive drums.

When allowing the ETB to engage back with the photosensitive drums, the DC controller turns on the
ETB alienation solenoid (SL3) again. The transfer roller engaging/disengaging cam rotates and
pushes the transfer roller holder. Accordingly, the transfer rollers push the ETB into contact with the
photosensitive drums.

Calibration and cleaning
The MFP automatically calibrates and cleans itself at various times to maintain the best print quality.
You can also force the MFP to calibrate by selecting QUICK CALIBRATE NOW or CALIBRATE
NOW from the PRINT QUALITY menu. For information about calibrating the MFP, see Table 5-4
Calibration timing and duration on page 191 or Table 5-5 Cleaning timing and duration on page 191 for
more information.
While the MFP is calibrating or cleaning, it pauses printing. For most calibrations and cleaning, the
MFP does not interrupt a print job, but waits for the job to complete before calibrating or cleaning.
Table 5-4 Calibration timing and duration on page 191 shows when the MFP calibrates, the duration
of the calibration, and the type of calibration that occurs. Table 5-5 Cleaning timing and duration
on page 191 shows when the MFP cleans and the duration of the cleaning. The sections that follow

ETB is returned to the photosensitive drum at once. The developing cylinder is disengaged from the
photosensitive drum during the cleaning operation to prevent toner in the toner container from
transferring onto the ETB.

Color misregistration corrective control
This control corrects a color misregistration caused by the variation inherent in the laser/scanner unit
and each cartridge. The color misregistration corrective control corrects the horizontal scanning
magnification, the horizontal scanning start position, and the vertical scanning start position.

192

Chapter 5

Theory of operation

ENWW

The DC controller controls the color misregistration unit under the following conditions:
●

At power on or door close after cartridge replacement

●

After job completion in every specified number of printings

●

At a command from the formatter

The following is the operational sequence of the color misregistration corrective control:
1.

The DC controller forms two pattern images for color misregistration detection with four colors
on the ETB when the color misregistration corrective control starts. The two pattern images are
the same pattern, one formed on the left side and the other on the right side.

The DC controller measures the position of each pattern image and calculates the
misregistration amount of each color by controlling the color misregistration unit.

The calculated misregistration information of each color is sent to the formatter.

The formatter controls each color’s video signals according to this information and optimizes the
main-scanning start position, the main-scanning scale, and the sub-scanning start position.

The color misregistration in sub-scanning direction is corrected at printer engine side by the DC
controller controlling the speed of the scanner motor.
NOTE Horizontal magnification is the size of the image in the horizontal direction. Every
color has its own photosensitive drum in each cartridge in this MFP. The positions of each
drum differ and the laser beam lengths vary because of the variations among the cartridges,
so the horizontal scanning area depends on the color. This causes a color misregistration at
the edge of image.

Color misregistration detection
In this MFP, the positions of each color’s misregistration pattern images formed on the ETB are
detected to measure the misregistration amount. The DC controller controls the color misregistration
unit during the foregoing color misregistration corrective control. The color misregistration unit is
placed under the ETB and consists of two detection sensors, each one having a light emitter (LED)
and a light receiver (PD).
The following is the operational sequence of the color misregistration detection.
1.

The DC controller allows the LED to emit light by sending the LED DRIVE signal when the color
misregistration detection starts.

The ETB reflects the light from the LED and the PD in the color misregistration sensor receives
the light. This reflected light intensity differs depending on whether the light is reflected from the
area of toner.

The light receiver converts the received light intensity into voltage and sends it in the form of the
color misregistration signal to the DC controller.

The DC controller detects the positions of the pattern images according to the timing of the color
misregistration signal.

Figure 5-31 Color misregistration detection on page 194 illustrates this process.

value whenever an error occurs.

Image stabilization control
This controls the variation of the image density caused by an environmental change or deterioration
of the photosensitive drum, toner, etc.
There are three types of image stabilization control. These controls operate when necessary.

194

●

Environmental change control. The environment condition sensor controls the bias according
to the environment conditions.

●

Image density control (D-max). The color misregistration sensor (PS12) calibrates the bias
value when the image density is at max.

●

Image halftone control (D-half). The color misregistration sensor (PS12) calibrates the
halftone data in the formatter.

Chapter 5

ENWW

Figure 5-32 Image stabilization control

Environmental change control
This control calibrates each bias to obtain the best image possible according to environmental
changes.
The environmental sensor detects the temperature and the humidity. The sensor sends this
information to the DC controller in the form of the temperature detection signal (TEMSNS) and the
humidity detection signal (HUMSNS).
The DC controller monitors the environmental conditions of the MFP based on these two signals.

ENWW

Image formation system

195

The DC controller controls the following biases to prevent image defects when it detects an
environmental change:
●

Developing bias

●

Primary transfer bias

●

Secondary transfer bias

If the environment sensor detects a temperature of below -30ºC (22ºF) or over 80ºC (176ºF), the DC
controller determines this is an "environment sensor abnormality" and sends an error message to the
formatter.

Image density calibration control (DMAX)
This control stabilizes image density by calibrating the values of the developing bias whenever one of
the following events occurs:
●

The detected temperature of the sub thermistor is below 50ºC (122ºF) when the MFP is turned
on.

●

The door is closed after a print cartridge or ETB is replaced.

●

A set number of pages is printed.

●

The specified value of environmental conditions has changed since the last image density
corrective control.

●

The formatter sends an operation command.

Image halftone calibration control (DHALF)
This control measures halftone density output from the formatter and returns the measurements to
the formatter so it can perform halftone calibration. Image density calibration must always be
performed before image halftone calibration.
Image halftone calibration control consists of three steps:
1.

The DC controller forms density patterns on the photosensitive drum in each color using the
optimum developing bias determined during image density calibration.

These density patterns are transferred to the ETB, and the color-registration detection unit
measures the image density of these patterns. Image data is returned to the formatter.

The formatter uses the image data to perform a halftone calibration to obtain an ideal halftone
image.

Image density detection
Each of the image stabilization controls uses the color registration unit at the top of the ETB to
measure image density. The image density detection is performed by the DC controller, which
controls the color misregistration unit during the D-half control. The color misregistration unit is
placed under the ETB and consists of two detection sensors, each having one light emitter (LED)
and one light receiver (PD). Figure 5-33 Image density detection on page 197 illustrates this process.

196

Chapter 5

Theory of operation

ENWW

The following is the operational sequence of the image density control:
1.

The DC controller allows the LED to emit light by sending the LED drive signal. The image
density detection control starts.

The density pattern images on the ETB reflect the light from the LED and the PD in the sensor
receives the light. This reflected light intensity differs depending on the toner density.

The light receiver converts the received light intensity into voltage and sends it as a toner
density signal to the DC controller.

The DC controller converts the toner density signal (analog) into a density value (digital) and
stores it.

The DC controller notifies the formatter of each error when the following errors are found during the
image density detection. When it fails to detect image density, it zeros the density data and notifies
the formatter.
●

Image density sensor abnormality warning: detected ETB surface density is improper.

●

Failed image density detection warning: detected density is improper.

Pickup/feed system
The pickup/feed system consists of various feed rollers that pick up and feed media. This MFP has
four pickup sources: the MP tray, tray 2, and the two trays of the 2 X 500-sheet paper feeder. The
primary delivery source is the face-down tray. The IPTU and stapler/stacker or 3-bin mailbox can
also be used for output.
The multipurpose tray paper sensor (SR4) detects the media presence in the multipurpose tray, and
the cassette paper sensor (SR9) detects the media presence in the cassette. The paper stack
surface sensor (SR10) in the cassette monitors the pickup position of the media stack surface. When
the SR10 detects that the pickup position lowers to a certain level, the DC controller lifts the lifting
plate up to maintain the media stack surface at a specified height. Figure 5-34 Pickup/feed system (1
of 2) on page 199 illustrates this system.
The media size in the cassette and presence of the cassette installed in the MFP are detected by the
cassette paper size detection switch (CSIZE SW). The cassette paper size detection switch consists
of three switches.
The DC controller controls ten motors: pickup motor, ETB motor, four drum motors, fuser motor,
fuser pressure release motor, reversing motor, and lifter motor. There are three solenoids: cassette
pickup solenoid, MP tray pickup solenoid, and duplexing solenoid, for the pickup operation.
There are five photo interrupters: top of page sensor, fuser paper sensor, paper loop sensor 1, paper
loop sensor 2, and paper reversing sensor, on the paper transport path to detect media arrival and
passage. If the media does not reach or pass these sensors within the specified period of time, the
microcomputer (CPU) on the DC controller determines the paper jam and notifies the formatter.

Chapter 5

Theory of operation

ENWW

Pickup/feed unit
The pickup/feed block is structured with two blocks. One is the pickup block, which picks up media
from the cassette or the multipurpose tray into the MFP one by one. The other one is the feed block,
which feeds the picked-up media to the fuser. The following sequence of events occurs:
1.

The DC controller rotates the pickup motor (M9), drum motors (M1, M2, M3, M4), ETB motor
(M7), and fuser motor (M5) after receiving a print command from the formatter.

The feed roller and the registration roller rotate as the pickup motor starts to rotate. The
cassette separation roller also begins to rotate. However, the separation roller does not rotate.

Media is picked from the cassette. The cassette pickup solenoid (SL2) is turned on after a
specified time after 'scanner ready'. This rotates the cassette pickup roller and cassette feed
roller to pick up media in the cassette.
Media is picked from the MP tray. The MP pickup solenoid (SL1) is turned on after a specified
time after 'scanner ready'. This rotates the MP tray pickup roller to pick up media in the tray.

Any multiple-fed media is removed by the cassette paper separation roller (paper separation
pad for the MP tray) and a single sheet is fed to the registration roller.

The skew of the media is corrected by the registration shutter. The media is then fed at its
prescribed speed. The formatter specifies the feed speed depending on the media type.

Toner is transferred to the media on the ETB, and the media is fed to the fuser/delivery block.

Cassette detection and cassette media size detection
The MFP can sense whether a cassette is installed correctly, and it can sense the size of the media
in the cassette. Paper-size detection switches at the back of the cassette send this information to the
DC controller. The DC controller determines which size is loaded by reading various switches. See
Table 5-6 Paper tray media size detection on page 203.

Although the cassette determines the media size by reading the switches, the user could select a

Pickup/feed system

203

The paper leading-edge sensor detects when the leading edge and the trailing edge of a sheet pass
it. By measuring the time between the passing of the leading edge and trailing edge, the sensor can
determine the actual size of the sheet. If this measured size differs from the size specified by the
formatter or the switch combination, the DC controller determines a mismatch. The sheet is ejected
from the MFP, and the MFP stops.

Cassette pickup operation
This MFP uses the pickup arm method for high-speed media pickup. The pickup arm presses the
pickup roller down on the media stack to feed the media one by one. The pickup roller is attached to
the pickup arm and it is normally held at the original position by the pickup arm. When the pickup
solenoid (SL2) is turned on, the pickup cam rotates and lowers the pickup roller onto the media.
The following is the operational sequence of the cassette pickup mechanism.
1.

When the DC controller turns the cassette pickup solenoid (SL2) on during the cassette pickup
operation, the driving force of the pickup motor (M9) causes the cassette pickup roller and the
pickup cam to rotate.

As the pickup cam rotates, the pickup arm goes down and the rotating cassette pickup roller
touches the media surface. The media in the cassette is fed into the MFP one sheet at a time.

The pickup cam rotation allows the pickup arm to go up and the cassette pickup roller
disengages from the media surface.

The cassette pickup roller stops rotating.

Figure 5-37 Cassette pickup on page 204 illustrates this process.

This operation maintains the position of the media stack surface at a specified height for a stable
pickup operation. The DC controller rotates the lifter motor (M10) and raises the lifting plate on which

the media stack is loaded. The DC controller monitors the cassette paper sensor (SR9) and the
media stack surface sensor (SR10) when the MFP is turned on, the cassette is installed, and during
the printing operation.
The media lifting operation is divided into two procedures:
●

Initial lift

●

Lifting during printing

Initial lift
The initial lift begins when the cassette is installed in the MFP and the lifting plate remains in the
bottom of the cassette. The DC controller continues driving the M10 until the SR10 detects media.
The SR10 lifts the stack surface up to the pickup position under the following conditions:
●

The SR9 and SR10 detect no media when the power is turned on.

●

The SR10 detects no media when the cassette is installed.

The DC controller stops this operation when the SR10 detects media before the SR9 detects media.
Lift-up during printing
The lifting during printing starts when the stack level reaches a specified level according to the
pickup operation. The DC controller drives the M10 when the SR10 detects no media during the
printing operation. The SR10 then lifts the stack surface up to the pickup position. Figure 5-38 Media
lifting on page 206 illustrates this process.
NOTE The paper lifting operation is also available for the 2 X 500-sheet paper feeders. The
initial lift for the cassette and paper feeders does not occur at the same time because of the
DC power supply limit. The operation starts from the bottom paper feeder and moves upwards.

Multiple-feed prevention
This MFP uses the paper separation roller method to prevent multiple feeds. The cassette paper
separation roller rotates in the same direction as the cassette feed roller. The paper separation roller
is imparted with a rotational force, transmitted through the torque limiter. If a multiple feed occurs, the
second paper is pushed back to the cassette and only one sheet is fed into the MFP.
Normally, the cassette paper separation roller is imparted with a rotational force in the same direction
to the cassette feed roller. However, since the paper separation roller touches the feed roller, driving
torque from the feed roller brings the torque limiter functions. The torque limiter shuts the rotational
force from the separation roller. The paper separation roller follows the rotational direction of the feed
roller, in the opposite direction. When the paper is not multiple-fed, the driving force from the feed
roller transmits through the single paper and allows the paper separation roller to rotate in the
opposite direction.
During a multi-feed, the rotational force of the cassette feed roller transmitted to the cassette paper
separation roller becomes weak because of the low friction between the sheets. The torque limiter
does not function and the paper separation roller rotates in the direction of the drive gear, causing

206

Skew correction
The skew correction mechanism compensates for the skew of feeding media. This MFP uses the
registration shutter method to avoid decreasing throughput.

ENWW

When the media is fed to the registration roller, the leading edge of the media hits the
registration shutter to compensate for the skew feeding.

The media is warped as the feed roller keeps pushing the media with the condition that the
media hit the registration shutter.

The stiffness of the media being warped lifts up the registration shutter and the media goes
through the shutter. The skew-feed is corrected without decreasing throughput.

Media detection
This MFP detects the media types to select the optimum print mode automatically. The DC controller
controls the media sensor during the printing operation for this detection. The media sensor contains
a light emitter (LED) and a light receiver. The light from the emitter is reflected off the media surface
or transmitted through the media. Each light is received at the light receiver.
NOTE The light receiver can detect even a slight difference in the light intensity because the
high-density pixels are integrated in a very small area.
The DC controller turns the media sensor on when the picked-up media passes through the
registration roller. Then it detects the roughness of the media surface, transmitted light intensity, and
thickness according to the patterns (luminance distribution within specified area) of the detected light

208

by the receiver. Accordingly, the DC controller identifies the media type: either plain paper, thin
paper, thick paper, gloss paper, gloss film, or overhead transparency, and notifies the formatter.

The DC controller switches the media feeding speed according to the detected media type when the
detected media type does not match the selected print mode.
If the DC controller fails to communicate with the media sensor during the media detection, it detects
a media sensor failure and outputs a media sensor abnormality warning to the formatter.

Feed speed control
The type of media in the paper path dictates the speed at which it is fed. The DC controller can
change the feed speed according to type of media. Table 5-7 Paper size detection switch settings

The DC controller performs the following controls depending on the specified print mode.
●

OHT mode. If plain paper, other than OHT is detected, the DC controller determines a media
misprint. The DC controller lets the printing operation continue under the OHT mode only when
it detects the OHT. The same applies to the following sheets in a continuous printing. When the
DC controller outputs the wrong media, it notifies the formatter, cuts off the secondary transfer
bias, delivers the media, and then stops the printer engine.

●

Automatic mode. When automatic mode is selected, the MFP starts the printing operation in
the normal mode. If plain paper, thin paper, thick paper, gloss paper, gloss film, or OHT is
detected, the DC controller switches the print mode to the appropriate mode and executes the
printing operation. In continuous printing, the print mode will not change from the one selected
for the first sheet. However, if the DC controller detects media different from the first page, it
outputs a media misprint.

●

All other print modes. If media other than OHT is detected, the DC controller continues the
printing operation with the selected print mode. It outputs a media misprint only when it detects
OHT. The same applies to the following sheets in the continuous printing.

Fusing and delivery block
The fuser/delivery unit is structured with two blocks. One is the fuser block that fuses toner on the
media. The other is the delivery block, which delivers the fused media to the face-down tray or output
device. The following is the operational sequence of the fuser/delivery unit.

210

The media with toner transferred on the ETB is fed to the fuser.

The paper warp is adjusted with the fuser motor speed control. The feeding speed differs
between the ETB and the fuser, as different motors are used to drive them. This control keeps
the media with a specified warp to prevent image defects and media transport defects.

Chapter 5

Theory of operation

ENWW

The fusing sleeve and the fusing pressure roller fuse the toner onto the media. The media is
then delivered from the fuser.

The image fusing media sensor (SR1) detects the media delivered from the fuser, and then
delivers the media to the face-down tray or other output device.
NOTE If the face-down tray is full of media, the delivery tray paper-full sensor (SR2) detects
that it is full. The DC controller determines the face-down tray media is full, notifies the
formatter, delivers the media currently printing from the MFP, and stops the printer engine.
When the stack of media on the face-down tray is removed, the SR2 detects the media
absence and the printing operation resumes.

Loop control
The media is delivered from the ETB to the fusing pressure roller maintaining the specified warp for
the media type, to prevent image and media transport defects.
The feeding speed of the fusing pressure roller and the ETB are not exactly the same. The following
problems might occur when the media is fed into the fuser.
●

If the rotational speed of the fusing pressure roller is slower than that of the ETB, the media
warp increases and an image defect or media crease might occur.

●

If the rotational speed of the fusing pressure roller is faster than that of the ETB, the media warp
decreases and a color misregistration in the sub-scanning direction occurs as the fusing
pressure roller pulls the media.

To resolve these issues, two sensors are used depending on the media type specified by the
formatter. The sensors bifurcate the warp amount for thick paper and thin paper. The DC controller
monitors the paper loop sensor 1 (SR13) and the paper loop sensor 2 (SR14) to maintain the paper
warp at specified amount by changing the rotational speed of the fusing pressure roller.
Figure 5-42 Loop control on page 212 illustrates this process.

Fusing pressure release mechanism
This mechanism automatically releases the fusing pressure to improve media removal and prevent
fusing pressure roller deformation.
The DC controller rotates the cam driven by the fuser pressure release motor (M6) at the prescribed
timing. The lifting plate is pushed down and the fusing pressure roller is released. The fusing
pressure is released under the following conditions:
●

When a paper jam occurs

●

When the power is turned off

●

When Sleep mode is ON/OFF

Duplex feed unit
This MFP is equipped with an integrated duplexing unit. The duplexing reverse/duplexing feed unit is
structured into two blocks.
One is the duplexing reverse block, that reverses paper in preparation for duplex printing. The
second is the duplexing feed block, which delivers the reversed paper to the registration roller.

Duplexing unit

Figure 5-44 Duplex feed unit
The duplexing driver PCB controls the duplexing unit. An 8-bit microcomputer in the duplexing driver
PCB controls the sequences of the duplexing unit and serial communication with the DC controller.
The DC controller sends a command to the duplexing driver PCB at the necessary time. The
duplexing driver PCB drives each load, such as motors and solenoids, depending on these
commands. The duplexing driver PCB relays the status information of the duplexing unit to the DC
controller.
The MFP supplies +24VDC to the duplexing unit. The +3.3VDC is generated by +24V DC in the
duplexing driver PCB, which works for the component devices such as sensors and ICs. Figure 5-45

The media fed to the duplexing unit goes to the opposite direction and proceeds hitting along the
right plate by the oblique roller. This corrects the paper skew and the media is fed into the MFP. The
operational sequence of the duplexing feed is described in Figure 5-46 Duplexing feed on page 215.

Media that has been printed on one side passes through the fuser.

The DC controller sends the reversing command to the duplexing driver at the specified time
after the top of page sensor (SR12) detects the leading edge of paper. The prescribed time is
when the media arrives at the fuser.

Pickup/feed system

215

When the duplexing driver receives the reversing command, it turns on the duplexing solenoid
(SL8001) to move the duplexing deflector. The duplexing driver also rotates the reversing motor
(M8001) clockwise to feed the media to the duplexing unit.

The DC controller sends the duplexing pickup command to the duplexing driver after the
prescribed time from when the fuser paper sensor (SR1) detected the trailing edge of paper.
The prescribed time is when the media passes through the duplexing deflector.

The duplexing driver rotates the reversing motor (M8001) counter clockwise (CCW) to reverse
the media and feed it to the duplexing feed unit when it receives the duplexing pickup command.

The media is fed while hitting its edge to the right guide by the oblique roller in the duplexing
feed unit. Consequently, the paper skew is corrected and the starting position of the image in
main-scanning is determined.

The paper skew is again corrected by the registration shutter. Then the media is printed on the
other side and fed to the face-down tray or other output device.

The MFP can use the following three duplexing modes depending on the paper size and the print
mode. The formatter specifies each duplexing print operation. However, it cannot specify the
operation other than the printable size (LTR, legal, executive, A4, B5-JIS) and the print mode
(normal, thick paper, thin paper, gloss paper, gloss film) for the duplexing print.

Dual sheet mode. Duplexing of two sheets moving at once (all paper sizes print except legal).

Alternating complex mode. Duplexing of three sheets moving at once (all paper sizes print

Jam detection
The MFP uses the following sensors to detect the presence of media and to check whether media is
being fed correctly or has jammed:

216

●

Top-of-page sensor (SR12)

●

Fuser paper sensor (SR1)

Chapter 5

Theory of operation

ENWW

●

Delivery tray paper-full sensor (SR2)

●

Reversing paper sensor (SR8001)

The microprocessor on the DC controller checks for jams by timing the media as it moves past these
sensors. If the media does not pass the sensor in a specific period of time, the transport process is
stopped (the motors are turned off and the rollers no longer rotate) and a jam message displays on
the product control panel display.

Pickup delay jam
If the top-of-page sensor (SR12) does not detect the leading edge of the media within a specific
period of time after the media is picked up, the microprocessor on the DC controller PCB determines
that a pickup jam has occurred.
NOTE The MFP attempts to pick up the media several times before determining that a
pickup jam exists. The number of pickup attempts depends on the source (for example, four
attempts occur if tray 1 is the source).
The transport process stops and a 13.%1$2:02X.%2$1:X%3$1:X FUSER JAM message displays on
the product control panel display. For more information about jam messages, see Resolving control
panel messages on page 488.

Pickup stationary jam
If the top-of-page sensor (SR12) continues to detect the leading edge of the media after a specific
period of time has elapsed, the microprocessor on the DC controller PCB determines that a pickup
stationary jam has occurred.
The transport process stops and a 13.%1$2:02X.%2$1:X%3$1:X FUSER JAM message displays on
the product control panel display. For more information about jam messages, see Resolving control
panel messages on page 488.

Delivery delay jam
If the fuser paper sensor (SR1) does not detect the leading edge of the media within a specific period
of time after the top-of-page sensor detects the media, the microprocessor on the DC controller PCB

Residual paper jam
If the fuser paper sensor (SR1) detects paper during the WAIT or INTR period, or if the top-of-page
sensor or fuser paper sensor detect paper during the automatic delivery period, the microprocessor
on the DC controller PCB determines that a residual paper jam has occurred.
The transport process stops and a 13.%1$2:02X.%2$1:X%3$1:X FUSER JAM message displays on
the product control panel display. For more information about jam messages, see Resolving control

Reversing unit jam 1
If the paper reversing sensor (SR8001) does not detect the leading edge of the media within a
specified period after the duplexing driver receives a reversing command from the MFP, the
microprocessor on the DC controller PCB determines that a reversing unit jam 1 has occurred.
The transport process stops and a 13.%1$2:02X.%2$1:X%3$1:X FUSER JAM message displays on
the product control panel display. For more information about jam messages, see Resolving control

Reversing unit jam 2
If the paper reversing sensor (SR8001) continues to detect media for a specified period after it
initially detects the media, the microprocessor on the DC controller PCB determines that a reversing
unit jam 2 has occurred.
The transport process stops and a 13.%1$2:02X.%2$1:X%3$1:X FUSER JAM message appears on
the product control panel display. For more information about jam messages, see Resolving control

Duplexing pickup unit jam 1
If the top-of-page sensor (SR12) fails to detect the leading edge of media within the specified period
after the duplexing driver receives a duplexing pickup command from the MFP, the microprocessor
on the DC controller PCB determines that a duplexing pickup unit jam 1 has occurred.
The transport process stops and a 13.%1$2:02X.%2$1:X%3$1:X FUSER JAM message displays on
the product control panel display. For more information about jam messages, see Resolving control

Automatic delivery function
Any residual paper within the MFP is automatically delivered when the power is turned on or when
printing starts. If the top-of-page sensor (SR12) detects paper during the WAIT period, the DC
controller PCB detects that residual paper is present, notifies to the formatter, and stops printing. The
controller drives the motors and delivers the residual paper to the MFP when it receives an automatic
delivery command from the formatter.

Scanner system
The scanner system adds copying and sending functions to the standard MFP printing function. The
scanner assembly consists of an automatic document feeder (ADF) and a flatbed scanner glass
surface.
Original documents that are fed through the ADF are delivered to the ADF output bin, which is
underneath the ADF input tray. Printed copies are delivered to the output device that is attached to
the print engine.
The scanner unit has built-in duplexing capability for scanning two-sided documents.
Figure 5-48 ADF mechanical structure on page 219 shows a cross-section of the ADF.

The scanner lamp illuminates a small strip of the document (called the raster line). The mirrors direct
the light through the lens to the CCD. The CCD senses and records the light, creating an analog
representation of the raster line. If the ADF is being used, the document then advances in the ADF to
the next raster line. If the flatbed is being used, the carriage advances to the next raster line. This
advancing and collection process continues to the end of the sheet.
The image data is collected on the scanner controller PCB, where it is processed and sent to the
formatter.

ADF feed system
Pages from the original document enter the ADF from the ADF input tray. A separation roller and
separation pad work together to separate the top sheet from the stack. The page passes through a
set of registration rollers and two sets of feed rollers that advance the page. A set of delivery rollers
delivers the page to the ADF output bin. A bin-full sensor detects when the ADF output bin is full, and
stops the feed mechanism until the bin is emptied.

ADF jam detection
When the sensors inside the ADF detect a jam, the feed and read motors immediately stop and send
a signal to the scanner controller PCB, which notifies the formatter. An ADF Paper Jam message
displays on the product control panel display.
To clear a jam, open the jam access cover and remove the media. If no sensors detect media after
the jam access cover is closed, the jam message is cleared from the product control panel display.

Residual media jam
During the initialization sequence or after the ADF jam cover has been opened and closed, the
registration sensor, read sensor, and exit sensor are checked for residual media jams. If a sensor
detects the presence of media, the scanner controller PCB detects a residual media jam.

ADF pickup jam
If the leading edge of the media did not reach the registration sensor within a specific period of time,
the scanner controller PCB determines that an ADF pickup jam has occurred.

ADF jam
Jams can occur in three places inside the ADF: at the registration sensor, read sensor, and exit
sensor.

ENWW

Scanner system

223

Registration sensor jam
If the registration sensor does not detect the trailing edge of the media after the leading edge
reaches the scan ready position, the scanner controller PCB determines that an ADF paper jam has
occurred.
Also, when the scanner duplexer is being used, if the registration sensor does not detect the leading
edge of the media after a specific period of time after media enters the duplexer, the scanner
controller PCB determines that a jam has occurred.

Read sensor jam
If the read sensor does not detect the leading edge of the media within a specific period of time, or if
the read sensor does not detect the trailing edge of the media within a specific period of time after it
detects the leading edge, the scanner controller PCB determines that a jam has occurred.

Exit sensor jam
If the exit sensor does not detect the leading edge of the media within a specific period of time after
the leading edge reaches the read sensor, or if the exit sensor does not detect the trailing edge of
the media within a specific period of time after the read sensor detects the trailing edge, the scanner
controller PCB determines that a jam has occurred.

ADF cover-open jam
If the ADF jam access cover is opened while media is feeding through the ADF, a jam occurs.

2 X 500-sheet paper feeder
The MFP includes a 500-sheet paper tray (tray 2) and a larger paper deck that contains two 500sheet feeders (trays 3 and 4). The paper path is shown below.

Figure 5-53 2 X 500-sheet feeder paper path
The paper feeder driver PCB controls the 2 X 500-sheet feeder operation sequences. The
microprocessor in the paper feeder driver controls the 2 X 500-sheet feeder sequences and the
communication with the DC controller PCB.
The paper feeder driver drives the solenoid in response to the pickup command. The paper feeder
driver also reports the paper feeder status to the DC controller PCB.
The MFP delivers a charge of +24 V to the paper feeder, which then generates +3.3 V for the
integrated circuits.

Chapter 5

Theory of operation

ENWW

Figure 5-55 2 X 500-sheet feeder pickup and feed diagram

ENWW

The DC controller receives a print command from the formatter and sends a pickup command to
the paper feeder driver.

The paper feeder driver rotates the pickup motor (M8101) in the paper feeder, and the feed
roller and the paper feeder separation roller start to rotate.

The DC controller sends the paper feeder pickup start command to the paper deck driver PCB
after the scanner is ready.

The paper deck driver PCB then rotates the paper deck pickup motor (M8201) clockwise to
rotate the paper deck feed roller.

The paper deck driver PCB turns on the paper feeder pickup solenoids (SL8201 and SL8202) to
rotate the paper deck pickup roller and the paper feeder feed roller. At the same time, the PCB
lowers the paper feeder pickup roller. As the pickup roller lowers, it contacts the media surface
and media in the cassette is fed into the MFP.

The separation roller eliminates extra sheets, and a single piece of media enters the feed path.

If the paper stack level goes down to the specified level according to the pickup operation, the
paper lifting operation is performed.

2 X 500-sheet paper feeder

227

NOTE Paper-size detection, multiple-feed prevention, and jam detection for the 2 X 500sheet feeder function in the same manner as the rest of the MFP.
NOTE Paper lifting operation for the 2 X 500-sheet feeder is the same as that of tray 2,
except that the paper feeder driver PCB controls this operation instead of the DC controller.

2 X 500-sheet jam detection
The paper feed sensor (SR8201) detects abnormal feed operation in the 500-sheet paper feeder.
These jams can occur:
●

Paper deck pickup delay jam: If the paper feed sensor (SR8201) does not detect the leading
edge of the media within a specified period after the paper is picked up, the microprocessor on
the DC controller PCB determines that a pickup jam has occurred.

●

Paper deck pickup stationary jam: If the paper feed sensor (SR8201) continues to detect
paper after a specific period of time has elapsed, the microprocessor on the DC controller PCB
determines that a paper deck pickup stationary jam has occurred.

For other jams, see Jam detection on page 216.

Output devices
This section describes the theory of operation for these components:
●

IPTU

●

3-bin mailbox

●

Stapler/stacker

IPTU
The IPTU (intermediate paper transfer unit) is installed at the face-down delivery area of the MFP. Its
function is to transfer paper to the installed output device, such as the stapler/stacker and the 3-bin
mailbox. The standard face-down tray should be removed when installing the IPTU. Paper flow is
illustrated in Figure 5-56 IPTU paper path on page 229.

To delivery options

Figure 5-56 IPTU paper path
The IPTU is controlled by the intermediate paper transfer driver PCB (IPTD PCB). The IPTD PCB
controls the IPTU sequencing and communicates with the DC controller. The DC controller sends
commands to the IPTD PCB at appropriate points in the printing process and the IPTD PCB drives
motors in response to these commands. The IPTD PCB submits status information to the DC
controller.
The MFP supplies +24VDC to the IPTU. The +3.3V for IC is generated by +24V in the IPTD PCB.
Figure 5-57 IPTU PCB flow on page 230 shows the signal flow in the IPTD PCB.

The IPTD turns feed motor 1 (M8301) and feed motor 2 (M8302) ON to rotate the feed rollers
upon receiving the drive start command.

The feed rollers deliver the paper to the output device.

IPTU jam detection
The IPTU is equipped with paper detection sensors to detect the presence of paper and to determine
operational status:
●

Top of page sensor (SR8301)

●

Delivery sensor (SR8302)

The CPU on the IPTD PCB determines a paper jam by checking whether paper is present at the
sensors at the checking timing. The checking timing is stored in the memory of the CPU. If the CPU
determines a jam, it stops the intermediate paper transfer operation and notifies the MFP of the jam.
Pickup delay jam
The CPU determines a pickup delay jam when the top-of-page sensor (SR8301) does not detect the
paper within the specified period after the cassette pickup solenoid (SL2) or the MP tray pickup
solenoid (SL1) is turned ON.
Pickup stationary jam
The CPU determines a pickup stationary jam when the top-of-page sensor (SR8301) does not detect
the trailing edge of the paper within the specified period after the top-of-page sensor (SR8301)
detects the leading edge.
Delivery delay jam
The CPU determines a delivery delay jam when the delivery sensor (SR8302) does not detect the
leading edge of the paper within the specified period after the top-of-page sensor (SR8301) detects
the trailing edge.
Delivery stationary jam
The CPU determines a delivery stationary jam when the delivery sensor (SR8302) does not detect
the trailing edge of the paper within the specified period after the top-of-page sensor (SR8301)
detects the trailing edge.

3-bin mailbox
When the 3-bin mailbox (MBM) is installed, it receives printed media from the print engine and
delivers it to one of its three bins. The 3-bin mailbox has the following components:
●

One feed motor that drives the rollers

●

Two solenoids that operate the inlet deflector and the bin deflector

●

Six sensors that detect the presence of print media and the stack height in the output bins

●

One switch that determines whether the 3-bin mailbox is attached to the MFP correctly

●

One fan that cools components inside the 3-bin mailbox

The 3-bin mailbox has three operating modes: stacker mode, mailbox mode, and function separator
mode.
The MBM driver PCB controls all functions in the 3-bin mailbox. To deliver media to the different
bins, the inlet deflector and the bin deflector change position as required.

232

233

Stacker mode
When configured for stacker mode, the 3-bin mailbox fills the bottom output bin (bin 3) first and then
fills the next highest bin.

Figure 5-60 Media flow when using the stacker mode

Mailbox mode
When configured for mailbox mode, the 3-bin mailbox stacks print media in each bin as determined
by the print job specifications. For example, one user might have all jobs delivered to the bottom bin,
and another user might have all jobs delivered to the top bin.

Function separator mode
When configured for function separator mode, the 3-bin mailbox delivers print media to each bin as
specified by the job type. For example, all copy jobs might be delivered to the top bin, and all faxes
might be delivered to the middle bin.

3-bin mailbox jam detection
The 3-bin mailbox uses the inlet sensor (PS1501) to detect jams. The microprocessor on the MBM
driver PCB determines a jam situation if the sensor indicates that media is present at an unexpected
time or that media is not present at the expected time. The microprocessor on the MBM driver PCB
notifies the formatter that a jam has occurred.
When a jam is detected, the transport process stops and a 13.%1$2:02X.%2$1:X%3$1:X FUSER
JAM message displays on the product control panel display. For more information about jam
messages, see Resolving control panel messages on page 488.
Feed delay jam
If the inlet sensor (PS1501) does not detect the leading edge of the media within a specific time
period after receiving a delivery notice command, the microprocessor on the MBM driver PCB
determines that a feed delay jam has occurred. The time interval is longer for face-up delivery than
for face-down delivery.

234

Chapter 5

ENWW

Feed stationary jam
If the inlet sensor (PS1501) does not detect the trailing edge of the media within a specific time
period after it detects the leading edge, the microprocessor on the MBM driver PCB determines that
a feed stationary jam has occurred.
Residual media jam
If the inlet sensor (PS1501) detects the presence of media during the initial WAIT period, the
microprocessor on the MBM driver PCB determines that a residual media jam has occurred.

Stapler/stacker
When the stapler/stacker is installed, it receives print media from the print engine and delivers it to
the stapler or stacks it in the output bin. The stapler/stacker has the following components:
●

Four motors that operate the paddle, the jogger, the feed mechanism, and the stapler unit

●

One clamp solenoid

●

Nine sensors that detect the media position and guide positions

●

One switch that detects when the stapler door is open

The stapler/stacker has two operating modes: staple mode and stacker mode.
The stapler/stacker driver PCB controls all functions in the stapler/stacker.

Staple mode
When the print job specifications require stapling, the pages of the document are gathered inside the
unit. A jogger aligns the pages horizontally, and a paddle aligns the pages vertically. When all pages
of a job are gathered, a clamp compresses the stack and a staple is attached.
After the document is stapled, the jogger guides spread apart to release the stack, and the stapled
document falls into the stacker bin.

Figure 5-62 Jogger operation (top view)

Stacker mode
The stacker mode collates multiple-page print jobs without stapling them.
When the print job requires no stapling, the pages of the document are gathered inside the unit. A
jogger aligns the pages horizontally, and a paddle aligns the pages vertically. When all pages of a
job are gathered, the jogger guides spread apart, releasing the stack, and the document falls into the
stacker bin without being stapled.

Staple jam detection
The stapler/stacker uses the inlet sensor (PS1301) and the delivery sensor (PS1302) to detect jams.
The microprocessor on the stapler/stacker driver PCB determines a jam situation if the sensor
indicates that paper is present at an unexpected time or that paper is not present at the expected
time. The microprocessor on the stapler/stacker driver PCB notifies the formatter that a jam has
occurred.
When a jam is detected, the transport process stops and a 13.%1$2:02X.%2$1:X%3$1:X FUSER
JAM message displays on the product control panel display. For more information about jam
messages, see Resolving control panel messages on page 488.
Feed delay jam

period after receiving a delivery notice command, the microprocessor on the MBM driver PCB
determines that a feed delay jam has occurred.

Feed stationary jam
If the inlet sensor (PS1301) does not detect the trailing edge of the media within a specific time
period after it detects the leading edge, the microprocessor on the MBM driver PCB determines that
a feed stationary jam has occurred.
Delivery stationary jam
If the delivery sensor (PS1302) does not detect the trailing edge of the media within a specific time
period after the feed motor has begun rotating, the microprocessor on the MBM driver PCB
determines that a delivery stationary jam has occurred.
Residual media jam
If the inlet sensor (PS1301) detects the presence of media during the initial WAIT period, the
microprocessor on the MBM driver PCB determines that a residual media jam has occurred.
Stapler unit
The stapler unit holds the staple cartridge and the staple motor. The staple cartridge contains up to
10,000 staples. The stapler unit also has three sensors that detect the presence of staples and
staple jams.

238

●

The staple home position sensor (PHOI1) detects when the stapler is in the correct position. If
the stapler is in the incorrect position, the staple/stacker driver PCB notifies the formatter that a
staple jam has occurred.

●

The staple ready sensor (PHOI2) detects when the stapler is self-primed after a new staple
cartridge is installed. If the sensor determines that the self-priming function was unsuccessful,
the staple/stacker driver PCB notifies the formatter that a staple jam has occurred.

●

The staple presence sensor (PHOI3) detects the number of staples in the staple cartridge.
When the number of staples in the cartridge is 20 or fewer, the stapler/stacker driver PCB
notifies the formatter. A STAPLER LOW ON STAPLES message displays on the product
control panel display.

Screws used in the MFP
The following table describes the screws that are used in the MFP and provides guidelines to help
determine where each type of screw is used. The screws can vary in length depending on the
thickness of the material that is being fastened. Always note where each type of screw is located and
replace each one in its original location.
NOTE When you are disassembling the MFP, place the screws into the chassis holes from
which they were removed. This prevents their loss, and ensures that the correct type and
length of screw for each location is used when the MFP is reassembled.
Table 6-1 Common fasteners used in this MFP
Drawing and description

Purpose
This screw is used to fasten metal to metal when good electrical contact is
needed. This screw also provides high resistance to loosening.

Phillips-head machine screw with
captive star washer
This screw is used to fasten sheet metal or plastic to plastic frames (the deep,
coarsely spaced threads provide an increased holding capability while decreasing
the possibility of stripping the target hole).
NOTE To install a self-tapping screw, first turn it counterclockwise to
align it with the existing thread pattern, and then carefully turn it
clockwise to tighten it. You will feel resistance and hear the screw click
when it engages the existing threads in the hole. Do not overtighten the
screw. If a self-tapping screw-hole becomes stripped, repair the screwhole or replace the affected assembly.

Troubleshooting process
When the MFP malfunctions or encounters an unexpected situation, information on the control panel
alerts you to the situation. This section contains an initial troubleshooting checklist that helps to
eliminate many possible causes of the problem. The subsequent troubleshooting flowchart helps you
to diagnose the cause of the problem. The remainder of the chapter provides steps for correcting the
problems that have been identified.
●

Use the initial troubleshooting checklist to evaluate the source of the problem and to reduce the
number of steps that are required to fix the problem.

●

Use the troubleshooting flowchart to pinpoint the cause of malfunctions. The flowchart lists the
section within this chapter that provides steps for correcting the malfunction.

Before beginning any troubleshooting procedure, check the following:
●

Are supply items (for example, the print cartridge, fuser, and rollers) within their rated life?
Does the configuration page reveal any configuration problems? See Information pages
on page 640.
NOTE The customer is responsible for checking and maintaining supplies, and for using
supplies that are in good condition. The customer is responsible for media and print-cartridge
supplies. The customer is also responsible for replacing the fuser, transfer roller, and all paper
pickup, feed, and separation rollers (tray 1 has a separation pad instead of a roller) that are at
or near the end of their 225,000-page rated life.

Initial troubleshooting checklist
If the MFP is not responding correctly, complete the steps in the following checklist, in order. If the
MFP does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolves
the problem, you can stop without performing the other steps on the checklist.

Troubleshooting checklist

ENWW

Make sure the MFP Ready light is on and the display says Ready. If no lights are on, see
Power-on checks on page 487.

Check the cabling.
a.

Check the cable connection between the MFP and the computer or network port. Make
sure that the connection is secure.

Make sure that the cable itself is not faulty by using a different cable, if possible.

Check the network connection. See Network connectivity problems on page 596.

Ensure that the print media that you are using meets specifications. See Media specifications
on page 18.

Print a configuration page (see Information pages on page 640.) If the MFP is connected to a
network, an HP Jetdirect page also prints.
a.

If the pages do not print, check that at least one tray contains print media.

If the page jams in the MFP, see Paper path troubleshooting on page 536.

Troubleshooting process

483

If the configuration page prints, check the following items.
a.

If the page prints correctly, then the MFP hardware is working. The problem is with the
computer that you are using, with the printer driver, or with the program.

If the page does not print correctly, the problem is with the MFP hardware. See Functional
checks on page 598.

Does the image quality meet the user's requirements? If yes, go to step 7. If no, check the
following items:
●

Print the print quality troubleshooting pages. See Print quality troubleshooting pages
on page 572.

●

Solve the print quality problems, and then go to step 7.

At the computer, check to see if the print queue is stopped, paused, or set to print offline.
Windows: Click Start, click Settings, and then click Printers or Printers and Faxes. Doubleclick HP Color LaserJet 4730mfp.
-orMac OS X: Open Print Center (or Printer Setup Utility for Mac OS X v.10.2), and double-click
the line for the HP Color LaserJet 4730mfp.

484

Verify that you have installed the HP Color LaserJet 4730mfp series printer driver. Check the
program to make sure that you are using an HP Color LaserJet 4730mfp series printer driver.

Print a short document from a different program that has worked in the past. If this solution
works, then the problem is with the program that you are using. If this solution does not work
(the document does not print) complete these steps:
a.

Try printing the job from another computer that has the MFP software installed.

If you connected the MFP to the network, connect the MFP directly to a computer with a
parallel cable. Redirect the MFP to the correct port, or reinstall the software, selecting the
new connection type that you are using.

Power-on checks
The basic MFP functions should start up as soon as the MFP is plugged into an electrical outlet and
the power switch is pushed to the on position. If the MFP does not start, use the information in this
section to isolate and solve the problem.

Power-on troubleshooting overview
Turn on the MFP power. If the control panel display remains blank, random patterns appear, or
asterisks remain on the display, perform power-on checks to locate the cause of the problem.
During normal operation, the main cooling fan begins to spin briefly after the MFP power is turned
on. Place your hand over the holes in the rear cover, above the formatter. If the fan is operating, you
will feel a slight vibration and feel air passing into the MFP. You can also lean close to the MFP and
hear the fan operating. When this fan is operational, the DC side of the power supply is functioning
correctly.
After the fan is operating, the main motor turns on (unless the top cover is open, a jam condition is
sensed, or the paper-path sensors are damaged). You should be able to visually and audibly
determine if the main motor is turned on.
If the fan and main motor are operating correctly, the next troubleshooting step is to isolate print
engine, formatter, and control panel problems. Perform an engine test (see Engine test on page 598).
If the formatter is damaged, it might interfere with the engine test. If the engine test page does not
print, try removing the formatter and then performing the engine test again. If the engine test is then
successful, the problem is almost certainly with the formatter, the control panel, or the cable that
connects them.
If the control panel is blank when you turn on the MFP, check the following items.
1.

Make sure that the MFP is plugged into an active electrical outlet that delivers the correct voltage.

Make sure that the power switch is in the on position.

Make sure that the fan runs briefly, which indicates that the power supply is operational.

Make sure that the formatter is seated properly.

Make sure that the control panel display wire harness is connected. See Control panel
on page 250.

Make sure that the firmware flash memory card and the formatter are seated and operating
correctly. See Flash memory card (firmware) on page 287.

Remove any HP Jetdirect or other EIO cards, and then try to turn the MFP on again.
NOTE If the control panel display is blank, but the main cooling fan runs briefly after the
MFP power is turned on, try printing an engine test page to determine whether the problem is
with the control panel display, formatter, or other MFP components. See Engine test
on page 598.

Control panel messages
Messages that appear on the control panel display relay the normal status of the MFP (such as
Processing job.), or an error condition (such as CLOSE TOP COVER) that needs attention.
Resolving control panel messages on page 488 lists messages that require attention, or that might
raise questions. Messages are listed in alphabetical order, with numeric messages at the end of the
list. Not all messages are listed because some (such as Ready) are self-explanatory.
NOTE Some messages are affected by the AUTO CONTINUE and CLEARABLE
WARNINGS settings on the Configure Device menu, SYSTEM SETUP submenu, on the
control panel.

Using the MFP help system
This MFP features a help system on the control panel that provides instructions for resolving most
MFP errors. Certain control panel messages alternate with instructions about using the help system.

A critical firmware error has occurred that
caused the processor on the formatter to
abort operation. This type of error can be
caused by invalid print commands, corrupt
data, or invalid operations. In some cases,
electrical noise in the cable can corrupt
data during transmission to the printer.
Other causes include poor-quality parallel
cables, poor connections, or homegrown
programs. On rare occasions, the formatter
is at fault, which is usually indicated by a 79

NOTE The HP Color LaserJet 4730mfp stores MFP configuration information in the compact
flash memory. Always print a configuration page before and after (wait five minutes after the
MFP power is turned on) installing the parts in the above list to verify that the MFP
configuration information is restored from the compact flash memory to the NVRAM.

Formatter and DC controller
WARNING! Do not replace the formatter and the DC controller at the same time. If the
formatter and DC controller must both be replaced, install a replacement formatter first and
make sure that you install the compact flash memory from the removed formatter on the
replacement formatter before you turn the MFP power on.
If the formatter and DC controller need to be replaced, install a replacement formatter first. The
HP Color LaserJet 4730mfp stores MFP configuration information in the compact flash memory. The
compact flash memory from the removed formatter must be installed on the replacement formatter,
so that MFP configuration information (for example, the duplexing option, page counts, and serial
number) can be restored to the formatter and DC controller. After replacing the formatter and
installing the compact flash, turn the MFP power on. When the Ready message appears on the
control panel display, you must wait five minutes before using the MFP so that the MFP configuration
information can be restored from the compact flash memory to the NVRAM.
Turn the MFP power off, and replace the DC controller. Turn the MFP power on. When the Ready
message appears on the control panel display, wait five minutes before using the MFP so that the
MFP configuration information can be restored from the compact flash memory to the NVRAM.
After installing the replacement formatter and DC controller, perform a full calibration procedure three
times. See Calibrating the MFP on page 591.

Paper path troubleshooting
Use this information in this section to troubleshoot errors in the paper path.
Jam error messages occur if media fails to arrive at or clear the paper path sensors in the allowed
time. Dedicated paper sensors detect whether media is present in the sensor and whether media is
feeding normally. When the DC controller detects a jam, it immediately stops the printing process
and the appropriate jam message appears for the sensor that detects the jam. The diagram Figure
5-35 Pickup/feed system (2 of 2) on page 201 shows the locations of all the sensors in the MFP.

Jam locations
If a jam message appears on the control panel display, look for jammed paper or other print media in
the locations that are indicated in the following figure.

13.01.00 JAM INSIDE DRAWER
BELOW TRAY 1

See Jam in Tray 1 on page 544.

A 13.01.00 jam occurs when the paper
is late in arriving at the paper leadingedge sensor (SR12) in the paper
pickup assembly. This event could be a
no pick resulting in the absence of
media in the paper path, or could be a
sheet that was delayed and jammed
somewhere in the feed area between
the specified tray and the paper pickup
assembly.
If the jam occurs during a multiplepage document, media might arrive in
the fuser, but the jam is still a result of
the media arriving late to the paper
leading-edge sensor (SR12) from the
specified tray. The MFP will not boot
up if a 13.01.00 jam occurs.

ENWW

13.02.00 JAM INSIDE RIGHT DOORS

See Clearing jams in the right covers
on page 539.

A 13.02.00 jam occurs when the paper
leading-edge sensor (SR12) has been
triggered, but never clears. The media
remains in the registration assembly.
After opening and closing the front
covers and ETB, the MFP can boot up
when a 13.02.00 error exists, if the
sensor is stuck or media remains in the
sensor.

13.09.00 JAM INSIDE RIGHT UPPER

13.0A.00

See Clearing jams in the right covers
on page 539.

A 13.0A.00 jam occurs when the MFP
is trying to deliver sheets to the output
bin for a simplex job or, for a duplex
turnaround, when the paper was late
leaving or never left the fuser delivery
sensor (SR1). The media might have
been incorrectly loaded in the paper
trays, something in the fuser might be
obstructing the media, or the sensor
could be stuck or broken.
WARNING! The fuser is hot,
wait 10 minutes for it to cool
down.

13.12.00 JAM INSIDE UPPER RIGHT
DOOR

See Clearing jams in the right covers
on page 539.

A 13.12.00 jam occurs when the MFP
is trying to print a duplex print job after
the media has entered the fuser and
started back down the paper path, but
has never arrived at or was late getting
to the paper leading-edge sensor
(PS12). The media might have been
disturbed by an outside source, (for
example, someone might have
grabbed the media while it was turning
around), or something might be in the
fuser that is obstructing the media.

When clearing jams, be very careful not to tear jammed media. If a small piece of media is left in the
MFP, it could cause additional jams. If jams are a recurring problem, see Solving repeated jams
on page 555.
NOTE Loose toner might remain in the MFP after a jam and cause temporary print-quality
problems. These problems should clear up within a few pages.

Paper jam recovery
This MFP automatically provides paper jam recovery, a feature that allows you to set whether the
MFP should attempt to automatically reprint jammed pages. The options are:
●

AUTO: MFP will attempt to reprint jammed pages.

●

OFF: MFP will not attempt to reprint jammed pages.

●

ON: MFP will attempt to reprint jammed pages.
NOTE During the recovery process, the MFP might reprint several good pages that were
printed before the paper jam occurred. Be sure to remove any duplicated pages.

Situation

Solution

General repeated jam problems

Make sure that the media is loaded correctly in the trays and that all width
guides are set correctly.

Make sure that the tray is set for the size of media that is installed and that
the tray is not overloaded.

Try turning over the stack of media in the tray. If you are using prepunched
or letterhead paper, try printing from tray 1.

Do not use media that has been printed on previously or torn, worn, or
irregular media. See Media specifications on page 18.

Check the media specifications. (See Media specifications on page 18.) If
media is outside of the recommended specifications, problems can occur.

The MFP might be dirty. Clean the MFP as described in Cleaning the MFP
on page 99.

Check that all damaged or jammed media is removed from MFP.

The ADF might be dirty. Clean the ADF as described in Cleaning the ADF
delivery system on page 99.

Make sure that the media is loaded squarely and that the media-width
guides are adjusted to the sides of the media stack.

Make sure that no more than 50 sheets of 75 g/m2 (20 lb) bond paper are
loaded in the ADF.

Make sure that the paper is within the range of supported weight for the
ADF: 60–120 g/m2 (16–32 lb).

If the original document that is being copied has been folded or stapled,
flatten it as much as you can and smooth any wrinkles. Make sure the pages
are not stuck together where the staple was.

Media that has been pre-punched or perforated in any way might be difficult
to feed through the ADF. If the leading edge of the document is excessively
worn or frayed, try rotating the document 180 degrees before copying.

Make sure that the media is being stored correctly. If the media is too dry,
the sheets might stick together. See Media specifications on page 18.

Paper path troubleshooting

555

Persistent jams
If jams occur repeatedly, use the information in this section to diagnose the root cause of the
problem. The tables in this section list possible causes and recommended solutions for jams in each
area of the paper path. Items are listed in the order that you should use to investigate. In general,
items at the beginning of the list are relatively minor repairs. Items at the end of the list are more
complex repairs.

Basic troubleshooting for jams
Use the following basic troubleshooting process for jams:
1.

Gather data.

Identify the cause of the problem.

Fix the problem.

Data collection
To troubleshoot jams, gather the following information:
●

The exact jam error code that appears on the control panel display

●

The location of the leading edge of the media that is in the paper path

●

Whether media is in the paper path when the jam occurs or in the input tray

●

Whether the jam occurs at power-up or while media is moving

●

Whether the media is damaged and, if it is, where the damage occurs on the paper and where
in the paper path the sheet stops

●

Whether the jam occurs when feeding from one particular tray

●

Whether the jam occurs only when using duplex printing

●

Whether a particular type of media is jamming or not jamming

●

Whether any of the supplies are non-HP (non-HP supplies are known to cause jams)

●

Whether the customer is storing the media correctly, overloading the trays, damaging the edge
of the media during loading, or using media that has already been fed through the MFP

General paper path troubleshooting
Use the following suggestions to isolate the cause of the problem. After you have identified the
cause, use the tables in this section to find a recommended solution.
NOTE Use the paper path test in the DIAGNOSTICS menu to print pages while
troubleshooting.

556

●

View or print the event log and determine if a particular jam error occurs more often than others.
Try to identify a pattern.

●

Use the event log to determine the frequency of a particular jam. If a jam occurs repeatedly at
approximately the same page count, consider it a single jam that the customer tried to clear.

Chapter 7

Troubleshooting

ENWW

●

Try printing from all available input trays to identify whether the problem is isolated to one tray.

●

Print the job in both simplex and duplex modes to identify whether the problem occurs only in
one mode or the other.

●

Try printing on media from an unopened ream that has been stored correctly. If the jam does
not occur with this media, then the customer's media might be causing the problem.

●

If the jam occurs from when the MFP is turned on, check the paper path for small, torn pieces of
media. Also check for broken sensors or flags, and check for loose or defective connections.

●

If the media is torn, folded, or wrinkled (typically along the leading edge), inspect the paper path
for items that could be causing the damage.

●

If the user is using non-HP supplies, try replacing those supplies with genuine HP supplies to
see if the problem goes away.

●

If necessary, instruct the user about proper media storage, correct loading technique, and MFP
operation. Make sure the user knows not to grab paper in the output bin during duplex printing.

Paper path checklist
●

Verify that media is correctly loaded in the input trays and that all length and width guides are
set correctly.

●

Clean the MFP. Toner and paper dust in the paper path can inhibit the free movement of media
through the MFP and can block the sensors.

●

Use the paper path test in the DIAGNOSTICS menu to vary the input selections of the MFP to
determine if the problem is associated with a particular area of the MFP.

●

Worn rollers or separation pads can cause multifeeds. Check the condition of the pickup rollers
and separation pads. Bent separation tabs (on the front corners of the input trays) can cause
misfeeds and multifeeds. Replace the tray if necessary.

●

Defective paper-tray switches can cause jams by communicating the wrong paper size to the
formatter.

●

Defective paper sensors along the paper path might falsely signal a jam.

●

Scraps of media that remain in the paper path can cause intermittent jams. Always check that
the paper path is clear when cleaning the MFP and when clearing jams. Also, remove the fuser
and carefully check it for debris from jams.

Correcting print quality and copy quality problems
This section helps to define print quality problems and how to correct them. Often print quality
problems can be handled easily by making sure that the MFP is properly maintained, using print
media that meets HP specifications, or running a cleaning page.

Print quality problems associated with media
Some print quality problems arise from use of inappropriate media.
●

Use paper that meets HP paper specifications. See Media specifications on page 18.

●

The surface of the media is too smooth. Use media that meets HP paper specifications. See
Media specifications on page 18.

●

The printer driver setting might be incorrect. Be sure that you have selected the correct driver
setting for the paper that you are using.

●

The print mode might be set incorrectly, or the paper might not meet recommended
specifications. For more information, see Media specifications on page 18.

●

The transparencies you are using are not designed for proper toner adhesion. Use only
transparencies designed for HP Color LaserJet printers.

●

The moisture content of the paper is uneven, too high, or too low. Use paper from a different
source or from an unopened ream of paper.

●

Some areas of the paper reject toner. Use paper from a different source or from an unopened
ream of paper.

●

The letterhead you are using is printed on rough paper. Use a smoother, xerographic paper. If
this solves your problem, consult with the printer of your letterhead to verify that the paper used
meets the specifications for this MFP. See Media specifications on page 18.

●

The media sensing feature might not be selected. Select the feature at the control panel.

Overhead transparency defects
Overhead transparencies might display any of the image quality problems that any other type of
media could display, as well as defects specific to transparencies. In addition, because
transparencies are pliable while in the print path, they are subject to being marked by the mediahandling components.
NOTE Allow transparencies to cool at least 30 seconds before handling them.

566

●

On the printer driver’s Paper tab, select Transparency as the media type. Also, make sure that
the tray is correctly configured for transparencies.

●

Check that the transparencies meet the specifications for this MFP. See Media specifications
on page 18.

●

Handle transparencies by the edges. Skin oil on the surface of transparencies can cause spots
and smudges.

●

Small, random dark areas on the trailing edge of solid fill pages might be caused by
transparencies sticking together in the output bin. Try printing the job in smaller batches.

Chapter 7

Troubleshooting

ENWW

●

The selected colors are undesirable when printed. Select different colors in the software
application or printer driver.

●

If you are using a reflective overhead projector, use a standard overhead projector instead.

●

The media sensing feature might not be selected. Select the feature at the control panel.

Print quality problems associated with the environment
The MFP is operating in excessively humid, dusty, or dry conditions. Verify that the printing
environment is within specifications. See Environmental specifications on page 15.

Print quality problems associated with jams
●

Make sure that all media is cleared from the paper path. See Paper jam recovery on page 538.

●

The MFP recently jammed. Print two to three pages to clean the MFP.

●

The media does not pass through the fuser, causing image defects to appear on subsequent
documents. Print two to three pages to clean the MFP. If the problem persists, see the next
section.

●

The media sensing feature might not be selected. Select the feature at the control panel.

Understanding color variations
The printed output might not match the computer screen, and the colors printed on successive pages
might not match. While color variations are inherent in this printing method, they can indicate
changes in the printing environment, print media, or MFP components.

Common causes of color variation
The following list outlines the major causes of color variations between computers, programs, and
output devices.

ENWW

●

Halftone patterns that are produced on monitors and the types of patterns that are used in the
print jobs are different and might cause variations in the printed output.

●

The printed output differs from the image on the monitor because the monitor and the print
media have different reference values of black and white. The monitor screen has charcoal gray
for the black level, and the white on the monitor screen is actually blue. Black on the print media
is limited only by the fill capability of the printer, and most good-quality paper has a very high
white level. In addition, phosphor (used in color monitors) and toner have entirely different
spectra characteristics and different color-rendering capabilities. Differences between output are
common. Blues generally match better than reds.

●

The color of the ambient light changes the perception of color. Fluorescent light lacks many
colors that are present in incandescent light, and the color range of natural light is broader than
any artificial light. When comparing color, choose a standard light source for reference and
understand that the perceived color will change as the light changes.

●

Long-term color variations occur as paper ages. Use high-quality paper and protect the paper
from sunlight to help minimize discoloration.

Correcting print quality and copy quality problems

567

●

Environmental changes can cause color variation. The development process places a high
potential across an air gap to attract toner to the imaging drum. Changes in relative humidity
vary the point at which the toner travels to the imaging drum.

●

All consumable components have a finite life span. As these components reach the end of their
useful life, their ability to produce consistent print quality diminishes.

●

Paper roughness can cause colors to look different. Use standard paper.

Paper selection
For the best color and image quality, select the appropriate media type from the MFP menu or the
MFP control panel.

sRGB
Standard red-green-blue (sRGB) is a world-wide color standard originally developed by HP and
Microsoft as a common color language for monitors, input devices (scanners, digital cameras), and
output devices (printers, plotters). It is the default color space used for HP products, Microsoft
operating systems, the World Wide Web, and most office software that is sold today. sRGB is
representative of the typical Windows computer monitor today and the convergence standard for
high-definition television.
NOTE Factors such as the type of monitor you use and the room's lighting can affect the
appearance of colors on your screen. For more information, see Matching colors on page 572.
The latest versions of Adobe® PhotoShop®, CorelDRAW®, Microsoft Office, and many other
programs use sRGB to communicate color. Most importantly, as the default color space in Microsoft
operating systems, sRGB has gained broad adoption as a means to exchange color information
between programs and devices using a common definition that assures typical users will experience
greatly improved color matching. sRGB improves your ability to match colors among the printer, the
computer monitor and other input devices (scanner, digital camera) automatically, without the need
to become a color expert.

Color options
Color options enable optimal color output automatically for diverse types of documents.
Color options use object tagging, which allows optimal color and halftone settings to be used for
different objects (text, graphics, and photos) on a page. The printer driver determines which objects
are used on a page and uses halftone and color settings that provide the best print quality for each
object. Object tagging, combined with optimized default settings, produces great color out of the box.
In the Windows environment, the Automatic and Manual color options are on the Color tab in the
printer driver.
Setting color options to Automatic will typically produce the best possible print quality for color
documents. However, situations might occur when you want to print a color document in grayscale
(black and white) or want to change one of the color options.
●

Using Windows, print in grayscale or change the color options by using settings on the Color
tab in the printer driver.

●

Using a Macintosh computer, print in grayscale or change the color options by using the Color
Matching pop-up menu in the Print dialog box.

Restricting color printing
The HP Color LaserJet 4730mfp includes a Restrict Color Use setting for networked printers. A
network administrator can use the setting to restrict user access to the color printing features in order
to conserve color toner. If you are unable to print in color, see your network administrator.
1.

Press Menu.

Scroll to and touch PRINT QUALITY.

Scroll to and touch SYSTEM SETUP.

Scroll to and touch Restrict Color Use.

Scroll to and select one of the following options:

●

DISABLE COLOR: This setting denies the printer color capabilities to all users.

●

ENABLE COLOR: This is the default setting, which allows all users to use the printer color
capabilities.

●

COLOR IF ALLOWED: This setting allows the network administrator to allow color use for
select users. Use the embedded Web server to designate users who can print in color.

Press OKto save the setting.

The network administrator can monitor color usage for a specific HP Color LaserJet 4730mfp by
printing a color usage job log. See Testing the MFP operation on page 67.

Print in grayscale
Selecting the Print in Grayscale option from the printer driver prints a document by using black
toner. This option is useful for previewing preliminary copies of slides and hardcopy output, or for
printing color documents that will be photocopied or faxed.

Automatic or manual color adjustment
The Automatic color adjustment option optimizes the neutral gray color treatment, halftones, and
edge enhancements used for each element in a document. For more information, see your printer
driver online Help.
NOTE Automatic is the default setting and is recommended for printing all color documents.
Use the Manual color adjustment option to adjust the neutral gray color treatment, halftones, and
edge enhancements for text, graphics and photographs. To gain access the Manual color options, on
the Color tab, select Manual, and then select Settings.

Manual color options
Use manual color adjustment to adjust the Color (or Color Map) and Halftone options individually for
text, graphics, and photographs.
NOTE Some programs convert text or graphics to raster images. In these cases, the
Photographs settings also controls text and graphics.

Halftone options
Halftone options affect the resolution and clarity of your color output. You can select halftone settings
for text, graphics, and photographs independently. The two halftone options are Smooth and Detail.
●

The Smooth option provides better results for large, solid-filled print areas. It also enhances
photographs by smoothing out fine color gradations. Choose this option when uniform and
smooth area fills are top priority.

●

The Detail option is useful for text and graphics that require sharp distinctions among lines or
colors, or images that contain a pattern or a high level of detail. Choose this option when sharp
edges and details are top priority.

Neutral grays
The Neutral grays setting determines the method used for creating gray colors used in text,
graphics, and photographs.
Two values are available for the Neutral grays setting:
●

Black Only generates neutral colors (grays and black) using only black toner. This guarantees
neutral colors without a color cast.

●

4-Color generates neutral colors (grays and black) by combining all four toner colors. This
method produces smoother gradients and transitions to non-neutral colors, and it produces the
darkest black.

Edge control
The Edge Control setting determines how edges are rendered. Edge control has two components:
adaptive halftoning and trapping. Adaptive halftoning increases edge sharpness. Trapping reduces
the effect of incorrect color plane registration by overlapping the edges of adjacent objects slightly.

570

Chapter 7

Troubleshooting

ENWW

Four levels of edge control are available:
●

Maximum is the most aggressive trapping setting. Adaptive halftoning is on for this setting.

●

Normal is the default trapping setting. Trapping is at a medium level and adaptive halftoning is
on.

●

Light sets trapping at a minimal level, and adaptive halftoning is on.

●

Off turns off both trapping and adaptive halftoning.

RGB color
Two values are available for the RGB Color setting:
●

Default instructs the printer to interpret RGB color as sRGB. sRGB is the accepted standard of
Microsoft and the World Wide Web Organization (www).

●

Vivid instructs the printer to increase the color saturation in the midtones. Less colorful objects
are rendered more colorfully. This value is recommended for the printing business graphics.

●

Device instructs the printer to print RGB data in raw device mode. To render photographs
properly with this selection, you must manage image color in the program or operating system.

Adjusting color balance
This MFP features automatic color calibration to provide high-quality color output. In situations that
require critical color control, you can manually adjust the density balance of the four toner colors. The
available range for each color is from -5 to +5. The default value is 0.
CAUTION This procedure should only be performed by your network administrator.
Performing this procedure changes the color balance of the MFP by altering halftones, and
affects all print jobs.

To adjust color balance

571

Color selection process
The user selects the color in the program, but the operating system might convert or modify some
characteristics of the color before sending the information to the printer driver. The printer driver
might also modify color characteristics depending upon the selected output mode.
Any color characteristics that the printer driver or programs do not address are set to the printer
default. The default color might not match the color the user selected.

Matching colors
PANTONE® color matching
PANTONE® has multiple color-matching systems. PANTONE® Matching System is very popular and
uses solid inks to generate a wide range of color hues and tints. See http://www.hp.com for details
about how to use PANTONE® Matching System with this printer.

Swatch book color matching
The process for matching printer output to preprinted swatch books and standard color references is
complex. In general, you can obtain a reasonably good match to a swatch book if the inks that are
used to create the swatch book are cyan, magenta, yellow, and black. These are usually referred to
as process color swatch books.
Some swatch books are created from spot colors. Spot colors are specially created colorants. Many
of these spot colors are outside of the gamut of the printer. Most spot color swatch books have
companion process swatch books that provide CMYK approximations to the spot color.
Most process swatch books have a note about what process standards were used to print the swatch
book. In most cases they will be SWOP, EURO, or DIC. To get optimal color matching to the process
swatch book, select the corresponding ink emulation from the printer menu. If you cannot identify the
process standard, use SWOP ink emulation.

Cleaning the scanner glass
Clean the scanner glass only if dirt is visible, or if you are experiencing a decrease in copy quality,
such as streaking.
Clean the scanner by wiping it gently with a clean, slightly damp, lint-free cloth. Use an ammoniabased surface cleaner only when a water-dampened cloth does not clean the scanner glass. Spray
or pour the cleaner onto the cleaning cloth. Do not spray or pour the cleaner onto the scanner glass.

Calibrating the MFP
The MFP automatically calibrates and cleans at various times to maintain the highest level of print
quality. The user might also request the MFP to calibrate via the MFP’s control panel, using QUICK
CALIBRATE NOW or FULL CALIBRATE NOW located in the CALIBRATION and PRINT QUALITY
menu. QUICK CALIBRATE NOW is used for D-Half color tone calibration. If color density or tone
seems wrong, Quick Calibration can be run. Full Calibration includes the Quick Calibrate routines
and adds Drum Phase Calibration, Color Plane Registration (CPR), and copy parameter calibration
routines. If color layers (black, magenta, cyan, and yellow) on the printed page seem to be shifted
from one another, FULL CALIBRATE NOW should be run.
The HP Color LaserJet 4730 MFP incorporates a new feature to skip calibration when appropriate,
thereby making the MFP available more quickly. For example, if the MFP is powered off and on
quickly (within 20 seconds), calibration is not needed and will be skipped. In this case, the MFP will
reach the Ready state approximately one minute sooner.
While the MFP is calibrating and cleaning, the MFP will pause printing for the amount of time it takes
to complete the calibration or cleaning. For most calibrations and cleaning, the MFP will not interrupt
a print job, but will wait for the job to complete before calibrating or cleaning.

E-mail problems
If you are unable to send e-mails by using the digital send feature, you might need to reconfigure the
SMTP gateway address or the LDAP gateway address. Print a configuration page to find the current
SMTP and LDAP gateway addresses. See Information pages on page 640. Use the following
procedures to check if the SMTP and LDAP gateway addresses are valid.

To validate the SMTP gateway address
NOTE This procedure is for Windows operating systems.
1.

Open an MS-DOS command prompt: click Start, click Run, and then type cmd.

Type telnet followed by the SMTP gateway address and then the number 25, which is the
port over which the MFP is communicating. For example, type telnet 123.123.123.123
25 where "123.123.123.123" represents the SMTP gateway address.

Press Enter. If the SMTP gateway address is not valid, the response contains the message
Could not open connection to the host on port 25: Connect Failed.

If the SMTP gateway address is not valid, contact the network administrator.

To validate the LDAP gateway address
NOTE This procedure is for Windows operating systems.

ENWW

Open Windows Explorer. In the address bar, type LDAP:// immediately followed by the LDAP
gateway address. For example, type LDAP://12.12.12.12 where "12.12.12.12" represents

Functional checks
Use the following procedures to help diagnose and solve problems that occur in the print engine.

Engine test
To verify that the print engine (all components except the formatter, formatter DIMMs, EIO products,
and the stacker or stapler/stacker) is functioning, print an engine test page. Use a small, nonmetallic, pointed object to depress the engine-test switch, which is located on the back of the MFP.
NOTE The standard output bin must be installed in order for the engine-test page to print. If
either the stapler/stacker or the 3-bin mailbox is installed, a jam occurs.

Figure 7-11 Engine test print switch
The test page should have a series of vertical lines. The test page prints from the last tray that you
used. However, if the MFP has been turned off and then on since the most recent print job, the page
prints from tray 2. The MFP continuously prints test pages as long as the test-page switch is
depressed. The MFP cannot print a test page if it is in Sleep mode.
NOTE A damaged formatter might interfere with the engine test. If the engine-test page does
not print, try removing the formatter and performing the engine test again. If the engine test is
then successful, the problem is almost certainly with the formatter, the control panel, or the
cable that connects them.

Use the embedded Web server to view MFP and network status and to manage printing functions
from your computer instead of from the MFP control panel. The following are examples of what you
can do using the embedded Web server:
NOTE When the printer is directly connected to a computer, use the HP Easy Printer Care
Software to view the printer status.
●

View MFP status information.

●

Set the type of media that is loaded in each tray.

●

Determine the remaining life for all supplies and order new ones.

●

View and change tray configurations.

●

View and change the MFP control panel menu configuration.

●

View and print internal pages.

●

Receive notification of MFP and supplies events.

●

View and change network configuration.

The embedded Web server feature requires at least 48 MB of RAM and an HP Jetdirect print server
in order to connect to your network.
To use the embedded Web server, you must have Microsoft Internet Explorer 5.01 or later or
Netscape 6.2 or later for Windows, Mac OS, and Linux (Netscape only). Netscape Navigator 4.7 is
required for HP-UX 10 and HP-UX 11. The embedded Web server works when the MFP is
connected to an IP-based network. The embedded Web server does not support IPX-based MFP
connections. You do not have to have Internet access to open and use the embedded Web server.
When the MFP is connected to the network, the embedded Web server is automatically available.

Individual component diagnostics
From the diagnostics menu, you can run tests to check the status of various components in the MFP.
During many of the diagnostic tests, the MFP enters a special diagnostics mode, which allows you to
send print jobs and interact with the menus. The MFP stays in this mode until you press Stop and
then touch EXIT DIAGNOSTICS at the top of the DIAGNOSTICS menu. In some cases, the MFP
must re-initialize after performing a component-level diagnostic test.

LED diagnostics
Use the following procedure to help identify the cause of high-level printer problems. These problems
are indicated by abnormalities in the printer's power-on sequence. The LED that the procedure refers
to is on the formatter. This is a “heartbeat” LED that blinks on and off when the formatter is operating
correctly. Use Figure 7-12 Formatter LED on page 654 to locate the formatter LED.

ENWW

Does the LED blink with four fast bursts at power on? If no, then perform the following checks.
●

Check the firmware.

●

Check the memory.

●

Check the formatter.

Does the LED blink at a fast, steady rate during memory testing (one blink per 8 MB)? If no,
then perform the following checks.
●

Check the control panel display for an error code.

●

Check the memory.

●

Check the formatter.

Is the LED off for about eight seconds, while the boot code is decompressing, before the display
turns on? If no, then perform the following checks.
●

Check the firmware.

●

Check the control panel display for correct connections and operation.

●

Check the control panel display for an error code.

Does the LED blink at a steady rate of one blink per second? If no, then perform the following
checks.
●

Check the firmware.

●

Check the formatter.

●

Check the control panel display for an error code.

If the control panel display does not illuminate, perform an engine test to check the engine. You
must have paper loaded in Tray 2 for the engine test.

Engine diagnostics
This section provides an overview of the engine diagnostics that are available in the HP Color
LaserJet 4730mfp series MFP. The MFP contains extensive internal diagnostics that help in
troubleshooting print quality, paper path, noise, component, and timing issues.
Diagnostics mode
Some of the diagnostic tests automatically put the MFP into a special diagnostics mode. During the
special diagnostics mode the MFP can perform actions that would normally cause the MFP to enter
an error state. Always follow the control panel directions in the DIAGNOSTICS menu to exit the
special diagnostics mode correctly and return the MFP to a normal state.
Diagnostics that put the engine into the special diagnostics mode
Four diagnostic tests put the engine into a special state:
●

Disable cartridge check

●

Sensor test

●

Manual sensor test

●

Component test

While the MFP is in the special diagnostics mode, the following message should appear:
Ready Diagnostics mode
To exit press STOP
When the MFP is in the special diagnostics mode, these four tests appear in the menu and are
available to be run. To gain access into other diagnostic tests or to leave the special state, press
Stop, and then select EXIT DIAGNOSTICS. The MFP will reset itself, and then return to the normal
state.
NOTE You need to have a good understanding of how the MFP operates in order to use the
engine diagnostics successfully. Before proceeding with these diagnostic tests, make sure
that you understand the information in chapter 5 of this manual.

654

Chapter 7

Troubleshooting

ENWW

Diagnostic tests
Different tests can be used to isolate different types of issues. For component or noise isolation, you
can run the diagnostic test after removing the covers. Removing the covers provides a better view of
the areas that are being tested. To operate the MFP with the covers removed, the door switch (SW4,
callout 1) lever must be depressed (this is the door-closed position).
WARNING! Be careful when performing MFP diagnostics to avoid risk of injury. Only trained
service personnel should open and run the diagnostics with the covers removed. Never touch
any of the power supplies when the MFP is turned on.
NOTE Any time a cartridge is installed or removed while the covers are removed, the door
interlock must be cycled to simulate opening and closing the top cover in order for the engine
to recognize the change. The ETB must be closed and its connector must be depressed
before cycling the door switch, or the MFP will generate a 59.90 Printer Error. When the
covers are installed, the door switch and ETB connector are automatically operated. When the
covers are removed, you must perform these steps manually.

Paper path sensor test
The paper path sensor test checks for the presence of media at each of the sensors along the paper
path. After you have selected this test from the DIAGNOSTICS menu, you can print internal pages or
send a print job from a computer. As the media passes each sensor, the sensor's state is updated.
On the control panel display, each sensor is represented by a string of alphabetic letters followed by
a corresponding status for each sensor. Use Table 7-38 Manual sensor test letter designations
on page 657 to associate the letters that are shown on the control panel display with the sensor that
they represent. A “0” next to the letter indicates that no media is present. A “1” indicates that media is
present. Press Stop to stop the job, and then touch EXIT DIAGNOSTICS to exit the special
diagnostics mode.

printed to date. Typically this is required only when the formatter is replaced.

COLOR CYCLE COUNT

Select this item to set the total number of color pages that have been printed to
date. Typically this is required only when the formatter is replaced.

REFURBISH PAGE COUNT

Select this item to set the page count if you need to send the MFP for
refurbishment. This page count is stored in memory so that the correct Service ID
can be restored after the MFP is refurbished.

DOCUMENT FEEDER KIT COUNT

Select this item to set the number of pages that have been printed since the last
document-feeder kit was installed or the total number of pages that have been
printed on this MFP if a document-feeder kit has not yet been installed (during the
first 225,000 pages).

Document Feeder Kit Interval: X

Select this item to specify the number of pages that can be printed before a
Replace Document Feeder Kit message appears on the control panel display to
indicate that a document-feeder kit is required.

TRANSFER KIT COUNT

This item allows the service technician to reset the page count if the value is lost.
This is set initially at the factory to 0. A cleaning kit interval is set at the factory
that cannot be set in any menu item. The interval for the transfer kit is 200000
(the expected transfer kit life). This value is reset to 0 if the user sets the menu
item NEW TRANSFER KIT to YES in the RESETS menu

FUSER KIT COUNT

This item allows the service technician to reset the page count if the value is lost.
This is set initially at the factory to 0. A cleaning kit interval is set at the factory
that cannot be set in any menu item. The interval for the fuser is 100000 (the
expected fuser life). Because color products stop when the kit count reaches the
interval, the user can only enter a value that is less than the fuser kit interval. This
value is reset to 0 if the user sets the menu item NEW FUSER KIT to YES in the
RESETS menu.

ADF COUNT

Select this item to set the total number of pages that have been fed through the
ADF.

FLATBED COUNT

Select this item to set the number of pages that have been scanned on the
flatbed glass.

COPY PAGES COUNT

Select this item to set the number of scanned pages that have been printed.

Scanner settings

CAUTION The Scanner settings are used for factory adjustments and
should not be used by service personnel. Use the scanner calibration
routine to adjust the scanner settings if necessary. See Calibrating the
scanner on page 106.

Cartridge Serial Number: X

Select this item to update the serial number if you replace the formatter.

Service ID

Service ID. Select this item to specify the date when the MFP was first used,
rather than the date when a replacement formatter is installed.
NOTE This should occur automatically if the formatter is replaced
without also replacing the DC controller. If the DC controller is also
replaced, ensure that the engine is rebooted between replacement of the
formatter and the DC controller.

ENWW

COLD RESET PAPER

Select this item to reset the default paper size when you replace the formatter or
restore factory settings. When you replace a formatter or restore factory settings
in a country/region that uses A4 as the standard paper size, use this item to reset
the default paper size to A4. Letter and A4 are the only cold-reset values available.

RESTORE ACCESSORY DATA NOW

This item appears when only one external device is attached to the print engine.
When selected, data is immediately restored. This option is used to restore
external device settings following repair. The old accessory information must be
restored before 10 pages have been printed with the new accessory, or the old
data will be overwritten.

RESTORE DATA FOR ACCESSORY

This item appears when more than one external device is attached to the print
engine. When selected, a list of devices for which data can be restored is
displayed. This option is used to restore external device settings following repair.
The old accessory information must be restored before 10 pages have been
printed with the new accessory, or the old data will be overwritten.

MEDIA SENSOR VALUE

Set this value to the value shown on the replacement paper feed assembly label
when the paper feed assembly is replaced.

Service ID
This information appears on the configuration page, which eliminates the need for customers to keep
paper receipts for proof of the warranty.

Converting the service ID to an actual date
You can use the MFP Service ID number to determine whether the MFP is still under warranty. Use
the following procedure to convert the Service ID into the installation date.
1.

Add 1990 to YY to determine the actual year that the MFP was installed.

Divide DDD by 30, and add 1 to the whole-number part of the quotient. The total is the month.

The remainder from the calculation in step 2 is the day of the month.

Using the Service ID 12287 as an example, the date conversion is as follows:

664

12 + 1990 = 2002, so the year is 2002.

287 divided by 30 = 9 with a remainder of 17. Add 1 to 9 to get 10, so the month is October.

The remainder (from the above calculation) is 17, so that is the day of the month.

The complete date is 17-October-2002.

Troubleshooting

ENWW

Troubleshooting the embedded HP Jetdirect print server
If network-connection errors occur, you can disable the HP Jetdirect print server in order to
determine if the problem is with the print server or with the network. This procedure requires that you
temporarily install an optional EIO HP Jetdirect print server card while disabling the embedded
HP Jetdirect print server.
To disable the embedded HP Jetdirect print server
1.

Turn the MFP off and then on.

When the memory count appears on the control panel display, press and hold 6 until all three
LEDs flash once and then stay on. This might take up to 20 seconds.

Release 6, and then press and release 3 until EMBEDDED LAN DISABLE appears on the
control panel display.

Press 6 one time, and wait for the MFP to complete its initialization sequence.
NOTE To enable the HP Jetdirect print server again, perform this same procedure.
EMBEDDED LAN ENABLE appears on the control panel display instead of EMBEDDED
LAN DISABLE.

Firmware-stack trace
In rare instances, you might need to work with a call-center escalation agent to find the source of a
49.XX.XX PRINTER ERROR. Use the firmware-stack trace procedure to collect data that the agent
might need. A firmware-stack trace indicates which firmware commands were executing at the time
of the error. The firmware-stack trace procedure does not produce a report. Instead, you must write
down the firmware instructions that appear on the control panel display and relay them to the agent.
To perform a firmware-stack trace

ENWW

When the error message appears on the control panel display, press 6 and then press 5.

Press 9 to scroll through each line of the firmware-stack trace.

Introduction
The figures in this chapter illustrate the major field replaceable unit (FRU) assemblies and
subassemblies in the MFP. A table (parts number list) follows each assembly diagram. The tables list
a reference number for each specific part, the part number, and a brief description of the part.
NOTE In this manual, the abbreviation "PCB" stands for "printed circuit board." Components
described as a PCB may consist of a single circuit board or a circuit board plus other parts,
such as cables and sensors.
NOTE Parts that do not have a reference number or part number are not FRUs, and cannot
be ordered as individual replacement parts. However, all serviceable parts should be available
as part of a larger operable subassembly.
The following lists of supplies and accessories were current at the time of printing. Availability
of accessories might change during the life of the MFP.
CAUTION When looking for an electrical part, pay careful attention to the voltage that is
listed in the part description column to ensure that the component part number that you select
is for the correct MFP model.
