HP’s Premium Protection print-cartridge warranty

Extended warranty
In most countries/regions, HP Care Pack provides additional coverage, beyond standard
warranty, for the HP device and for all HP-supplied internal components. This hardware
maintenance can uplift the standard warranty, for example, from next-day to same-day
service, and/or extend it up to 5 years. HP Care Pack can also provide Express Exchange or
onsite service. For more information, see the support flyer that came with your device for the
appropriate phone numbers and information.

Chapter 1 Product information

ENWW

Print-cartridge information
The print cartridge is designed to simplify replacement of the major consumable parts. The
print cartridge contains the printing mechanism and a supply of toner.
At 5 percent page coverage, a standard print cartridge will print approximately 2,500 pages.
As page coverage increases, yield decreases. These estimates are only approximate; usage
conditions and print patterns can cause results to vary.

Refilled print cartridges
While Hewlett-Packard does not prohibit the use of refilled print cartridges during the warranty
period or while the product is under a maintenance contract, it is not recommended for the
following reasons:
●

Repairs resulting from the use of refilled cartridges are not covered under Hewlett-Packard
warranty or maintenance contracts.

●

Hewlett-Packard has no controls or processes to ensure that a refilled cartridge functions
at the high level of reliability of a new HP LaserJet print cartridge. Hewlett-Packard also
cannot predict the long-term reliability effect on the product from using different toner
formulations found in refilled cartridges.

●

The print quality of HP LaserJet print cartridges influences the customer’s perception of
the product. Hewlett-Packard has no control over the actual print quality of a refilled
cartridge.

●

Parts that are critical to print quality might not be replaced when the cartridge is refilled
with toner.

HP LaserJet printing supplies
In many countries/regions, this product's printing supplies (for example the print cartridge) can
be returned to HP through the HP Printing Supplies Returns and Recycling Program. An
easy-to-use and free take-back program is available in more than 30 countries/regions.
Multilingual program information and instructions are included in every new HP LaserJet print
cartridge and supplies package.

HP Printing Supplies Returns and Recycling Program
information
Since 1990, the HP Printing Supplies Returns and Recycling Program has collected millions
of used LaserJet print cartridges that otherwise might have been discarded in the world's
landfills. The HP LaserJet print cartridges and supplies are collected and bulk shipped to our
resource and recovery partners, who disassemble the cartridges. Remaining materials are
separated and converted into raw materials for use by other industries to make a variety of
useful products.
U.S. returns
For a more environmentally responsible return of used cartridges and supplies, HP
encourages the use of bulk returns. Simply bundle two or more cartridges together and use
the single, pre-paid, pre-addressed UPS label that is supplied in the package that the new
cartridge comes in. For more information in the U.S., call (1) (800) 340-2445 or visit the HP
LaserJet Supplies website at http://www.hp.com/recycle.

Guidelines for using media
Use the information in this section to choose the proper print media.

Paper and transparencies
Paper must be of good quality and free of cuts, nicks, tears, spots, loose particles, dust,
wrinkles, holes, and curled or bent edges. Check the label on the paper package for details
about the type of paper (such as bond or recycled).
Some paper causes print-quality problems, jamming, or damage to the printer.
Note

Do not use letterhead that is printed with low-temperature inks, such as those used in some
types of thermography; raised letterhead; or colored paper or preprinted forms that use inks
incompatible with the printer temperature (200° C, or 392° F, for 0.1 second).
Transparencies must be able to withstand 200° C (392° F), the printer's maximum
temperature.

Do not use media that has cutouts or
perforations.

Problems with feeding.

Ragged edges.

Use good-quality media.

Labels
Note

For best results, use only HP-brand labels. To order HP supplies, visit http://www.hp.com.
When selecting labels, consider the following factors:
●

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

●

Arrangement: Use only 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 inch) of curl in any
direction.

●

Condition: Do not use labels that contain wrinkles, bubbles, or other indications of
separation. Never use a sheet of labels that has already been run through the printer.

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 on the quality of the envelopes. When selecting envelopes, consider the
following factors:
●

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

●

Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch)
curl and should not contain air. Envelopes that trap air can cause problems.

●

Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise
damaged.

●

Sizes: Supported envelope sizes range from 90 by 160 mm (3.5 by 6.3 inches) to 178 by
254 mm (7 by 10 inches).

Store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope
might wrinkle during printing.

ENWW

Guidelines for using media

Envelopes with double-side seams
An envelope with double-side-seam construction has vertical seams at both ends of the
envelope rather than diagonal seams. This style is more likely to wrinkle during printing. Make
sure that the seam extends all the way to the corner of the envelope as shown in the following
illustration:

Envelopes with adhesive strips or flaps
Envelopes with 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 (200° C, or 392° F) and pressure in the
printer. The extra flaps and strips might cause wrinkling, creasing, or jams.

Envelope storage
Store envelopes flat to ensure good print quality. If air is trapped in and envelope, creating an
air bubble, the envelope might wrinkle during printing.

Card stock and heavy media
Some card stock performs better than others because the construction is better suited for
feeding through a laser device. For optimum performance, do not use media that is heavier
than 163 g/m 2 (43 lb). Media that is too heavy might cause misfeeds, stacking problems,
jams, poor toner fusing, poor print quality, or excessive mechanical wear.
Note

You might be able to print on heavier media if you do not fill the input tray to capacity and if
you use media that has a smoothness rating of 100 to 180 Sheffield. Use the straight-through
paper path for heavier media.

Card stock construction

●

Smoothness: 135 to163 g/m 2 (36 to 43 lb) card stock should have a smoothness rating
of 100 to 180 Sheffield. 60 to 135 g/m 2 (16 to 36 lb) card stock should have a smoothness
rating of 100 to 250 Sheffield.

●

Construction: Card stock should lie flat with less than 5 mm (0.2 inch) of curl.

Guidelines for using media

Loading media
This section provides information about loading media in the input trays.

Media input tray
The media input tray holds up to 250 sheets of 75-g/m2 (20-lb) paper or a 25-mm (0.98-inch)
stack of heavier media. Load media with the top forward and the side to be printed on facing
up. To prevent jams and skew, always adjust the side media guides.

Priority input tray
The priority input tray holds up to ten pages of 75-g/m2 (20-lb) paper or one envelope,
transparency, or card. Load media with the top forward and the side to be printed on facing
up. To prevent jams and skew, always adjust the side media guides.
If you try to print on media that is wrinkled, folded, or damaged in any way, a jam might occur.
See the user guide on the product CD for more information.
Note

When you add new media, make sure that you remove all of the media from the input tray and
straighten the stack of new media. This helps prevent multiple sheets of media from feeding
through the printer at one time, reducing jams.

Specific types of media

●

Transparencies and labels: Load transparencies and labels with the top forward and the
side to be printed on facing up. See the user guide on the product CD for more
information.

●

Envelopes: Load envelopes with the narrow, stamp side forward and the side to be
printed on facing up. See the user guide on the product CD for more information.

●

Letterhead and preprinted forms: Load with the top forward and the side to be printed
on facing up. See the user guide for more information.

●

Cards and custom-sized media: Load with the narrow side forward and the side to be
printed on facing up. See the user guide on the product CD for more information.

Chapter 2 Operation

ENWW

Selecting originals for the automatic document feeder (ADF)
Use either the ADF or the flatbed scanner for most copying, scanning, and faxing needs.

Specifications for ADF originals

Note

●

Input capacity: The ADF holds up to 50 sheets of flat, 60- to 90- g/m2 (16- to 24-pound)
plain paper.

●

Media size: Use only plain paper that is within the following size range:
–

Minimum: 127 mm by 127 mm (5 by 5 inches)

–

Maximum: 215.9 mm by 381 mm (8.5 by 15 inches)

You must use the flatbed to scan or copy small or delicate originals (such as newsprint,
business cards, and photos), or documents that have tears, perforations, or punch holes. If
you want to fax such items, first make a copy on the flatbed and then fax the copy.
Perform the following actions to minimize the possibility of jams:

Note

ENWW

●

Remove self-stick notes.

●

Remove staples and paper clips.

●

Straighten any curls, folds, or wrinkles in documents before putting them into the
document feeder tray.

●

Do not insert any document that contains glue, correction fluid, or wet ink.

●

Do not insert gum-backed paper or labels.

●

Avoid multiple-copy forms.

●

Do not scan originals that are larger or smaller than supported size limitations. See the
user guide on the product CD for more information.

To obtain good results, it is important to use the correct re-entry and color settings for the job.
See the user guide on the product CD for more information.

Selecting originals for the automatic document feeder (ADF)

Media information for the flatbed
Use the flatbed scanner for copying, scanning, and faxing if the media is fragile, thin, thick, or
damaged (folded, wrinkled), or to produce a high-quality copy or file. The flatbed scanner
provides the best copy and scan quality.
The flatbed has no minimum size specification, and accepts a maximum size of legal-size
media (215.9 mm by 355.6 mm, or 8.5 inches by 14 inches). In order to make a copy of a
legal-size document, the paper size must be changed by using the PAPER SIZE button.
Otherwise, the copy will be cropped to the default paper size.

Printer output paths
The HP LaserJet 3380 all-in-one has two output paths. Use the main output bin when printing
normal and large, collated documents. Use the straight-through output path when printing
envelopes, transparencies, heavy media, or any media that tends to curl when printed.

Output bin and straight-through output path
The output bin is located between the scanner and the printer. Printed media is collected here
in the correct sequence when the straight-through output door is closed.
To use the straight-through output path, open the straight-through output door on the rear of
the product. Multipage documents are delivered in reverse order when the straight-through
output door is open.

ENWW

Formatter system
The formatter coordinates the major systems. It is responsible for the following tasks or
actions:
●

controlling the motor controller board

●

formatting and controlling copies

●

receiving and processing print data from the printer interface

●

monitoring the control panel and relaying printer-status information

●

developing and coordinating data placement and timing with the print engine

●

communicating with the host computer through the bidirectional interface

●

communicating fax data to and from the LIU

The formatter receives print data from the bidirectional enhanced capabilities port (ECP) mode
interface or universal serial bus (USB) interface and converts it into a dot image. The ECU
synchronizes the image-formation system with the paper-feed system and signals the
formatter to send the print-image data. The formatter sends the print-image data (dots) in the
form of a video signal, and the printing process begins.

Central processing unit
The formatter incorporates an embedded 32-bit Coldfire V4e processor operating at 90 MHz.

Line interface unit (LIU)
The LIU provides the required safety isolation, signal coupling, and impedance matching
between the telephone line and the modem chipset that is located on the formatter.

Motor controller PCA
The motor controller PCA contains motor-driver circuitry for the ADF motor and the scanmodule position motor. The motor controller PCA also provides electrical interface from the
formatter to the control-panel PCA and to the speaker.

Flash memory
The formatter system includes firmware code that controls the product. The code is stored in
flash memory, which allows the firmware code to be recovered or updated. The firmware
update and recovery process is described in Troubleshooting.

Standard boot process
When the product is unplugged or the power is off, the firmware code is stored on the
formatter in two blocks. The first block of code is an executable boot block (about 64 K of
code). The second block of code is a compressed version of the product control code.
When the product is turned on, the boot block decompresses the product control code and
stores it in RAM. Then the product performs a full startup with the control code running from
RAM.

RAM
The product contains two types of random-access memory (RAM):
●

One bank of nonvolatile RAM (NVRAM) stores parameters.

●

Dynamic random access memory (DRAM) provides temporary storage of the product
program code along with copy, scan, and print data.

Parallel interface or universal serial bus (USB) interface
The formatter receives incoming data through its bidirectional ECP or USB interface. These
interfaces provide high-speed, two-way communication between the product and the host,
allowing you to change product settings and monitor product status from the host computer.

Control panel
The control panel consists of the following features:
●

six groups of buttons to control fax, copy, scan, and configuration functionality

●

a 2-by-16 LCD display that shows status, menus, and messages

●

two front-panel status lights (one next to the CANCEL button and one next to the FAX/SEND
button)

EconoMode (Draft mode)
When you select EconoMode in the printer driver, the product uses less toner, which extends
the life of the print cartridge. Using EconoMode produces a lighter image because less toner is
on the page.

Chapter 4 Operational overview

ENWW

MEt
HP Memory Enhancement technology (MEt) effectively doubles the standard memory through
a variety of font- and data-compression methods.

Enhanced I/O
The enhanced I/O (EIO) feature allows product memory to be used for storing data received
from the host computer. When EIO is enabled, you can send more data to the product in
shorter amounts of time, so that you can return to the software program more quickly. The EIO
feature has the following options:
●

Auto —the product uses EIO memory allocation to increase the speed of data transfer
from the host computer to the product, if necessary. The default setting is Auto.

●

Off —the minimum amount of product memory is used to store data that is sent from the
host computer.

●

Page Protect—the formatter creates the entire page image in page-buffer memory before
physically moving the media through the printer. This process ensures that the entire page
will be printed.

Page complexity (ruling lines, complex graphics, or dense text) can exceed the printer’s ability
to create the page image fast enough to keep pace with the image-formation process. If Page
Protect is disabled and a page is too complex, the page might print in sections (for example,
the top half on one page and the bottom half on the next page). Some print-data loss is likely
in these instances, and an error message will appear on the control-panel display.

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

ENWW

●

Two-way communication with the host computer through a bidirectional parallel
connection. The product can communicate information to the host (such as the controlpanel status).

●

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

Formatter system

Scanner and ADF functions and operation
The following sections describe how the document scanner and the automatic document
feeder (ADF) function.

Scanner functions
The scanner uses a light source, a color-separation method, and a charge-coupled device
array (CCD) to collect optical information about the document and transform that into an image
file. The scanner consists of these elements:
●

a lamp (cold-cathode fluorescent bulb)

●

five mirrors and a lens

●

a CCD
Scanner Glass
CCFL Lamp

600 ppi CCD

Lens

Figure 4-3.

Optical diagram of scanner
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 scanner module
advances to the next raster line. This advancing and collection process continues to the end
of the sheet.
The image data is collected in the motor controller board, where it is processed and sent to the
formatter. The formatter then handles the image data, outputting it as a copy, sending it
through the LIU as a fax, or directing it to the computer as scanner output.
The image data collected for scans is 600 pixels per inch (ppi). The image data collected for
copies is 300 ppi. Each pixel has 8 bits for each of the three colors (256 grayscale levels for
each color) or a total of 24 bits per pixel (24-bit color).

Chapter 4 Operational overview

ENWW

Scanner operation
At startup and periodically at other times, the scanner assembly moves systematically to
locate its home position. It then calibrates to a white strip located under the glass at the right
end of the scan tub.
If the product detects a document in the ADF when a copy or scan is initiated (from the
software or the control panel), the scan module moves to the left side of the scan tub and
stops. The image is acquired as the paper is fed through the ADF past the scanner module.
If no document is detected in the ADF, the scan module acquires the image from the flatbed
glass while slowly moving within the scan tub.

ADF operation
Standby (paper-loading) mode: In standby mode, the pickup roller is up and the stack-stop
is down, preventing the user from inserting the original document too far. When a document is
inserted correctly, the paper-present sensor detects its presence.
The standard operation of the ADF consists of the pick, feed, and lift steps.
Pick: When it receives a copy or scan command, the ADF motor engages the gear train to
lower the pickup-roller assembly and raise the stack-stop. The first roller, called the pre-pick
roller, moves the top few sheets forward into the ADF. The next roller is the pickup roller. This
roller contacts the ADF separation pad, which separates multiple pages into single sheets.
Feed: The single sheet continues through the path. Along the way, the form sensor, which is a
set distance from the ADF glass, detects the sheet. This alerts the scanner to start when the
page reaches the glass. The scanner acquires the image, one raster line at a time, until it
detects the end of the page. The page is then ejected. The pick and feed steps are repeated
as long as paper is detected in the ADF input tray.
Lift: When no more paper is detected in the ADF input tray and the form sensor detects the
trailing edge of the last page, the last sheet is ejected and the motor turns in a sequence that
lifts the pick roller assembly to standby (paper-loading) mode again.
The ADF will not function when the ADF lid is open. The paper path is incomplete if the ADF
lid is lifted from the glass.

Document scanner path
The paper-present sensor determines if paper is in the ADF. The form sensor detects the top
and bottom edges of the document. One other sensor detects an open ADF door.

ADF jam detection
The ADF has two sensors that detect paper. The paper-present sensor detects the presence
of media in the ADF input tray. The form sensor detects media moving through the ADF. If a
jam is detected, the ADF immediately stops the paper feeding and a jam message appears on
the control-panel display.
A jam can be detected under any of the following conditions:

●

Document-feeder jam—When documents are detected in the ADF input tray, and a
command to copy, scan or fax is received, the scan module travels to the left side of the
scan assembly and stops beneath the ADF scanner glass. The ADF then attempts three
times, or for about ten seconds, to advance the paper to the form sensor. If the paper
does not advance, the scan module travels back to the home position on the right side of
the scanner assembly. The message Document feeder mispick. Reload. appears on the
control-panel display.

●

Long-document jam—If the paper has advanced to trigger the form sensor, but the
trailing edge is not detected within the time allowed for a 381-mm (15-inch) document (the
maximum allowable page length for the ADF), the scanner returns to the home position at
the right side of the scanner assembly. The message Doc feeder jam. Clear, Reload.
appears on the control-panel display.

●

Stall jam—When a page that is less than 381 mm (15 inches) long has advanced to the
form sensor but has not left it within the expected time, the paper has probably stalled or
jammed. The scanner returns to the home position at the right side of the scanner
assembly. The message Doc feeder jam. Clear, Reload. appears on the control-panel
display.

●

Other—If the paper stops in the ADF and the scan module remains under the ADF
scanner glass, an internal firmware error has probably occurred. This is usually remedied
by cycling the power.

ECU loads

Power system within the ECU
The ac, dc, and high-voltage power supply circuits are all contained within the ECU.
Ac power distribution
The ac power circuitry supplies ac voltage whenever the power cord is connected to the ac
power source. Ac voltage is distributed to the dc power supply circuitry and to the ac driver
circuitry, which controls ac voltage to the fuser assembly heating element.
Dc power distribution
The dc power distribution circuitry, located on the ECU, distributes +3.3 Vdc, +5 Vdc, +24
Vdc, and +32 Vdc as follows:

High-voltage power distribution
The high-voltage power supply applies an overlap of dc and ac voltage to the primary-charging
roller and the developing roller. This circuit also applies a positive or negative dc voltage to the
transfer roller according to the instructions from the engine control unit.

Chapter 4 Operational overview

ENWW

This circuit also controls the image density by changing the primary ac voltage and the
developing ac bias according to the print-density setting. Figure 4-7. High-voltage power
supply circuit shows the high-voltage power supply circuit.

Figure 4-7.

High-voltage power supply circuit
Low-voltage power distribution
The low-voltage power supply circuit converts ac power into +24 Vdc, +5 Vdc, and +3.3 Vdc
as required by the printer. The +24 Vdc is divided into +24 V, which is supplied constantly from
the low-voltage power supply circuit, and +24 U, which is supplied to the high-voltage power
supply circuit and which acts as the door-open detection. When the top cover is open, the
door-open switch (SW301) cuts the +24 U to the high-voltage power supply circuit.
The circuit contains a fuse for overvoltage protection. FU101 breaks and cuts power if
overcurrent flows through the power cord. FU102 (on 110-127 V models) breaks at a lower
amperage, as required for lower-voltage units.
In addition, the +24 Vdc and +3.3 Vdc power circuitry contains an overcurrent protection
circuit that automatically shuts off dc voltage output to prevent power-supply failures if current
flow is excessive or voltage generation is abnormal. The circuit automatically resets itself when
the printer is turned off.

ENWW

Printer functions and operation

Paper-motion monitoring and control
The ECU controls paper motion in the printer by continuously monitoring the various paper
sensors and coordinating the timing with the other print processes.
For a detailed explanation of paper movement and the interaction of the photosensors and
solenoid with the paper-motion process, see Printer paper-feed system.

Motors
The ECU controls the motors. The main motor provides all of the paper movement in the
printer. The fan motor rotates the fan to cool the printer.

Printer laser/scanner drive
The laser/scanner system is controlled by the ECU, which sends laser control signals CNT0,
CNT1, and CNT2, and by the formatter, which sends video signals /VDO1, VDO1, /VDO2, and
VDO2.

Figure 4-8.

Overview of laser/scanner operation

Chapter 4 Operational overview

ENWW

Image-formation system
Laser printing requires the interaction of several different technologies, including electronics,
optics, and electrophotographics, to provide a printed page. Each process functions
independently and must be coordinated with the other printer processes. Image formation
consists of seven processes:

Figure 4-9.

Image-formation block diagram

The seven image-formation processes
1. Conditioning stage (primary charging)—This process applies a uniform negative
charge to the surface of the drum with the primary-charging roller, which is located in the
print cartridge. The primary-charging roller is coated with conductive rubber. An ac bias is
applied to the roller to erase any residual charges from any previous image. In addition,
the primary charging roller applies a negative dc bias to create a uniform negative
potential on the drum surface. The print density setting modifies the dc voltage.
2. Writing stage (scanning exposure)—During this process, a modulated laser diode
projects the beam onto a rotating scanning mirror. As the mirror rotates, the beam reflects
off the mirror, first through a set of focusing lenses, then off a mirror, and finally through a
slot in the top of the print cartridge, and onto the photosensitive drum. The beam sweeps
the drum from left to right, discharging the negative potential wherever the beam strikes
the surface. This creates a latent electrostatic image, which later is developed into a
visible image. Because the beam sweeps the entire length of the drum while the drum
rotates, the entire surface area of the drum can be covered. At the end of each sweep, the
beam strikes the beam-detect lens, generating the beam-detect signal (BD signal). The BD
signal is sent to the ECU, where it is converted to an electrical signal that synchronizes the
output of the next scan line of data.
3. Developing stage—During this process, the latent electrostatic image is present on the
drum. The toner particles obtain a negative surface charge by rubbing against the
developing cylinder, which is connected to a negative dc supply. The negatively charged
toner is attracted to the discharged (exposed, grounded) areas of the drum, and it is
repelled from the negatively charged (unexposed) areas.
4. Transfer stage—During this process, the toner image on the drum surface is transferred
to the media. The transfer roller applies a positive charge to the back of the media, which
attracts the negatively charged toner on the drum surface to the media. After separation,
the drum is cleaned and conditioned for the next image.
5. Separation stage—During this process, the media separates from the drum. To stabilize
the feed system and prevent toner dropouts on the printed image at low temperature and
humidity, the static eliminator reduces the charge on the back of the media.

ENWW

Printer functions and operation

6. Fusing stage—During this process, the heat and pressure fuse the toner into the media
to produce a permanent image. The media passes between a heated fusing element and a
soft pressure roller, which melt the toner and press it into the media.
7. Drum-cleaning stage—During this process, the cleaning blade is in contact with the
surface of the drum at all times. As the drum rotates during printing, the cleaning blade
wipes excess toner off the drum and stores it in the waste toner receptacle.

Print cartridge
As the focal point of the image-formation system, the print cartridge contains toner and houses
the cleaning, conditioning, and developing stages of the process. The print cartridge contains
the photosensitive drum, primary charging roller, developing station, toner cavity, and cleaning
station. By including these components (which wear, degrade, or are consumed) in the
replaceable print cartridge, the need for many service calls is eliminated. The special
photosensitive properties of the drum form an image on the drum surface and then transfer the
image to media.
CAUTION

The print cartridge does not include a light-blocking shutter. Do not expose the drum to light,
which can permanently damage the drum. Protect the print cartridge whenever you remove it.

Printer paper-feed system
The main input tray and the priority input tray merge into one main input area. Media placed in
any of these areas activates the paper detection sensor (PS931), which informs the ECU that
media is present. The following steps occur when the product receives a print job:

Step 1

The ECU activates the laser/scanner assembly and the motor. Paper motion begins when
the ECU energizes the solenoid (SL1).

Step 2

The paper-pickup roller rotates once. The paper-lift plate pushes the media against the
pickup roller.

Step 3

The pickup roller moves the top sheet and advances it to the feed assembly drive rollers.
To ensure that only one sheet is fed, a main separation pad and two subpads hold the
remainder of the stack in place.

Step 4

The feed-assembly drive rollers advance the media to the paper-top sensor (PS911). This
sensor informs the ECU of the exact location of the leading edge of media, so that the
image that is being written on the photosensitive drum can be precisely positioned on the
page.

Step 5

The feed-assembly drive rollers then advance the media to the transfer area, where the
toner image on the photosensitive drum is transferred to the media.

Step 6

After the image is transferred, the media enters the fuser assembly, where heat from the
fuser and pressure from the pressure roller permanently bond the toner image to media.
The paper-delivery sensor (PS921) determines that the media has successfully moved
out of the fusing area.

Step 7

The fuser assembly exit rollers deliver media to either the paper output bin or the
straight-through output path, according to the position of the straight-through output path
door.

Jam detection
The paper-detection sensor (PS931) detects the presence of media in either the priority input
tray or the main input tray. The paper-top sensor (PS911) and the paper-delivery sensor
(PS921) detect media moving through the printer. If a jam is detected, the ECU immediately
stops the printing process and a jam message appears on the control-panel display.
A jam can be detected under any of the following conditions:

Chapter 4 Operational overview

ENWW

Fax functions and operation
The following sections describe the fax capabilities of the product.

PSTN operation
The public switched telephone network (PSTN) operates by having a central office (CO) that
generates a constant voltage on the TIP and RING wires (48 V, usually). A device goes onhook by connecting impedance (such as 600 ohms for the U.S.) across TIP and RING,
allowing a line current to flow. The CO can detect this current and can send impulses, such as
dial tones. The product generates more signaling tones, such as dialing digits, to tell the CO
how to connect the call. The product can also detect tones, such as a busy tone from the CO,
that tell it how to behave.
When the call is finally connected, the CO behaves as if it were a piece of wire connecting the
sender and receiver. This is the period during which all of the fax signaling and data transfer
occurs. When a call is completed, the circuit opens again and line current flow ceases,
removing the CO connection from both the sender and the receiver.
All of this is done with a two-wire arrangement. The two wires are called TIP and RING on all
phone systems. On most phone systems, the wires appear on pins 3 and 4 of the RJ-11
modular jack (the one on the LIU). These two wires do not have to be polarized because all
the equipment works with either TIP or RING on pin 3 and the other wire on pin 4. This means
that cables of either polarity can interconnect and will still work.
These are the basic functions of PSTN operation that are assumed in the design of the fax
subsystem. The product generates and detects the signaling tones, currents, and data signals
that are required to transmit and receive faxes on the PSTN.

The fax subsystem
The formatter, LIU, firmware, and software all contribute to the fax functionality. The designs
of the formatter and LIU, along with parameters in the firmware, determine the majority of the
regulatory requirements for telephony on the product.
The fax subsystem is designed to support V.34 fax transmission, lower speeds (such as V.17
fax), and older fax machines.

Formatter in the fax subsystem
The formatter contains the modem chipset (DSP and CODEC) that controls the basic fax
functions of tone generation and detection, along with channel control for the fax
transmissions.
The CODEC and its associated circuitry act to control transmit and receive gains, and to
compensate for transmission signal coupling into the receive channel. The formatter also
contains circuitry that adds termination impedance to help match the telephone network
impedance.

LIU in the fax subsystem
Two versions of LIU are used in the HP LaserJet 3380 all-in-one. One is used in the North
American, South American, and Asian countries/regions. The other is used primarily in
European countries/regions.

ENWW

Fax functions and operation

The following are features that are different in the European version:
●

a different voltage-protection device

●

current limiting of the dc current

●

filtering for the countries/regions that use billing or metering tones

●

control of the impedance of the dc circuit through the SHUNT signal

Because the TIP and RING are not polarized, all LIU circuitry that connects to TIP and RING
is bidirectional. The LIU operates identically when TIP and RING are reversed.

Safety isolation
The most important function of the LIU is the safety isolation between the high-voltage,
transient-prone environment of the telephone network (telephone network voltage [TNV]) and
the low-voltage analog and digital circuitry of the formatter (secondary extra-low voltage
[SELV]). This safety isolation provides both customer safety and product reliability in the
telecom environment.
Any signals that cross the isolation barrier do so either optically or magnetically. The
breakdown voltage rating of barrier-critical components is greater than 1.5 kV.

Safety-protection circuitry
In addition to the safety barrier, the LIU protects against RING and over-current events.
Telephone over-voltages can be either differential mode or common mode. The RING can be
transient in nature (a lightning-induced surge or ESD) or continuous (a power line crossed with a
phone line). The LIU protection circuitry provides margin against combinations of RING
events.
Common mode protection is provided by the selection of high-voltage-barrier critical
components (transformer, relay, and optoisolators). The safety barrier of the LIU PCB traces
and the clearance between the LIU and surrounding components also contribute to common
mode protection.
A voltage suppressor (a crowbar-type SIDACTOR) provides differential protection. This device
becomes low impedance at approximately 300 V differential, and crowbars to a low voltage. A
series thermal switch works in conjunction with the crowbar for continuous RING events, such
as crossed power lines.
When the differential RING is continuous, the resulting over-current causes the thermal switch
to become high impedance, disconnecting RING from the network and protecting the crowbar
from thermal overload. The thermal switch automatically resets to low impedance after the
over-current condition is removed, reconnecting RING to the network.

Data path
The magnetically coupled signals that cross the isolation barrier go either through a
transformer or a relay. The TIP and RING signals use a transformer to cross the isolation
barrier.
TIP and RING are the two-wire paths for all signals from the telephone network. All signaling
and data information comes across them, including fax tones and fax data.
The telephone network uses dc current to determine the hook state of the telephone, so line
current must be present during a call. On some line interfaces this current flows through the
transformer, but on the LIU, a capacitor blocks the current from going into the transformer.

Chapter 4 Operational overview

ENWW

Blocking the current with a capacitor prevents the core of the transformer from being saturated
by the high dc voltage, which can affect the ac signal quality. Rather than permitting the
current to flow through the transformer, this LIU directs the current through another circuit
called a gyrator or dc hold circuit. This creates the path for the central office-current flow when a
call is in progress.

Hook state
Another magnetically coupled signal is the control signal that disconnects the downstream
telephone devices (such as a phone or answering machine). A control signal originating on the
formatter can change the relay state, causing the auxiliary jack (downstream jack) to be
disconnected from the circuit.
The product takes control of calls that it recognizes as fax calls. If the product does not directly
pick up the call, it monitors incoming calls for the fax tone or for the user to direct it to receive a
fax. This idle mode is also called eavesdropping. This mode is active when the product is onhook but current exists in the downstream phone line because another device is off-hook.
During eavesdropping, the receive circuit is enabled but has a different gain from the current
that is generated during normal fax transmissions.
The product does not take control of the line unless it detects a fax tone or the operator tells it
to connect manually. This feature allows the user to make voice calls from a phone that is
connected to the product without being cut off if a fax is received.

Downstream current detection
The aux phone detect signal is optically coupled. This signal tells the firmware that an active
phone (or modem or answering machine) is connected to the auxiliary port of the product (the
right side of the RJ-11 jack).
A circuit that can detect current above a certain threshold generates the downstream-currentdetection signal. The downstream current goes through a resistor, generating a voltage. If this
voltage is above the threshold level, the signal changes state.
The downstream-current-detection signal is coupled back to the formatter through an
optoisolator and across the safety isolation barrier. The firmware uses this signal to ensure
that the product does not go off-hook (and disconnect a downstream call) until it has been
authorized to do so (by a manual fax start or detection of the appropriate tones).

Hook switch control
Another optically coupled signal is the hook switch control. This signal from the formatter
causes an optoisolator on the LIU to activate (making an open circuit into a short circuit).
When shorted, the circuit is drawing dc current from the central office and is considered “onhook.” When open, no dc current flows and the state is considered to be “off-hook.”
For pulse dialing, the optoisolator is toggled on and off with a particular timing sequence to
generate pulses that the central offices of the telephone company recognizes as dialing digits.

Ring detect
Another optically coupled signal on the LIU is ring detect. Ring detect is a combination of
voltage levels and cadence (time on and time off). Both must be present in order for the
product to detect a valid ring.
The LIU works with the firmware to determine if an incoming signal is an answerable ring.
When circuits on the LIU detect a ring voltage above a certain threshold, a corresponding
signal is passed to the formatter to indicate that the ring is above the threshold. The firmware
then measures the amount of time that the signal is high and low, and qualifies the cadence to
determine whether it is a valid ring.

ENWW

Fax functions and operation

Line current control
The dc current from the CO needs to have a path to flow from TIP to RING. Because the
current does not flow in the transformer, a path through some transistors and diodes (the dc
hold circuit) acts like a simulated inductor (thus replacing the function of the transformer). This
dc hold circuit is the main component of the voltage-current characteristic between TIP and
RING.
Two other functions of this block of circuits are the current limit and the SHUNT for Europe.
Current limit basically maintains a constant current from TIP to RING after the voltage reaches
about 50 mA. Even if the voltage varies, the current will remain the same.
The SHUNT function changes the impedance (the current-voltage characteristic) during
certain special events, such as pulse dialing and when the devices goes on-hook.
During such an event, the firmware tells the DSP on the formatter to activate SHUNT. A
signal goes to the LIU through an optoisolator (optically coupled), which changes the state of
some transistors so that the board has a linear current characteristic (normally, it is currentlimited). Then more current can flow to the network, as required by these special events.

Billing (metering) tone filters
Switzerland and Germany provide high-frequency ac signals on the phone line in order to bill
customers. The LC (inductor, capacitor) notch filters are provided on the European LIUs to
prevent these billing signals from adversely affecting the data path and the dc hold circuit.
An additional filter in the cable (for certain countries/regions) can, in some cases, supplement
these LC notch filters. Because these billings signals are not used in the U.S., these filters are
not present on the U.S. LIU.

Fax page storage in flash memory
Fax pages are the electronic images of the document page. They can be created in any of
three ways: scanned to be sent to another fax machine, generated to be sent by the
computer, or received from a fax machine to be printed.
The product stores all fax pages in flash memory automatically. After these pages are written
into flash memory they are stored until the pages are sent to another fax machine, printed on
the product, transmitted to the computer, or erased by the user.
These pages are stored in flash memory, which is the nonvolatile memory that can be
repeatedly read from, written to, and erased. The product has 4 MB of flash memory, of which
3.4 MB is available for fax storage. The remaining 0.6 MB is used for the file system and
reclamation. Adding RAM does not affect the fax page storage because the product does not
use RAM for storing fax pages.

Stored fax pages
The user can reprint stored fax pages in case of errors. Other fax devices store fax pages in
either normal RAM or short-term RAM. Normal RAM immediately loses its data when power is
lost, while short-term RAM loses its data about 60 minutes after a power failure. Flash memory
maintains its data for years without any applied power.

Advantages of flash memory storage
Fax pages stored in flash memory are persistent. They are not lost as a result of a power
failure, no matter how long the power is off. Users can reprint faxes in case the print cartridge
runs out of toner or the product experiences other errors while printing faxes.

Chapter 4 Operational overview

ENWW

The product also has scan-ahead functionality that makes use of flash memory. Scan-ahead
automatically scans pages into flash memory before a fax job is sent. This allows the sender to
pick up their original document immediately after it is scanned, eliminating the need to wait
until the fax is transmission is complete.
Because fax pages are stored in flash memory, not RAM, more RAM is available to handle
larger and more complicated copy and print jobs.

Removal and replacement strategy
This chapter documents the removal and replacement of field replaceable parts (FRUs) only.
Reinstallation is generally the reverse of removal. Occasionally, notes and hints are included
to provide directions for difficult or critical replacement procedures.
WARNING!

Unplug the power cord from the power outlet (at the wall receptacle) before attempting to
service the product. If this warning is not followed, severe injury can result. Certain functional
checks during troubleshooting must be performed with power supplied to the product.
However, the power supply should be disconnected during removal.
Sheet-metal and plastic edges in the product can be sharp. Use caution when servicing this
product.
Never operate or service the product with the protective cover removed from the laser/
scanner assembly. The invisible reflected beam can damage eyesight.

CAUTION

The product contains components that are sensitive to electrostatic discharge (ESD). Always
perform service work at an ESD-protected workstation. If an ESD-protected workstation is not
available, discharge body static by grasping the print-engine chassis before touching an
ESD-sensitive component. Ground the print engine chassis before servicing the product.

CAUTION

Do not bend or fold the flat-flexible cables (FFCs) during the removal or reinstallation process.

Note

For service purposes, the upper part of the HP LaserJet 3380 all-in-one is, in effect, the
"scanner" and the lower part is the "printer." Together, they also act as a photocopier or fax
machine, but the service description here is simplified by referring to copier or fax functionality
only when specifically necessary.

Scanner/printer separation required:
The scanner assembly might be contaminated if it is opened outside of a cleanroom
environment. For this reason, the entire scanner assembly is replaceable only as a unit.
Replacing the scanner assembly as an entire assembly replaces the CCD scan module, the
CCD scan motor, and the cable. If the ADF fails, it too is replaceable only as an entire
assembly. Replacing the ADF replaces the ADF cable and other ADF submechanisms.

Chapter 6 Troubleshooting

ENWW

Basic troubleshooting

Is Power-on successful?
When the product is connected to a grounded power source, the words Hewlett Packard appear with moving
cursors to indicate that the firmware code is loading, and the printer motor rotates for approximately 5 seconds.
When the firmware is done loading (30 to 40 seconds after power-on), the message Scanner Bulb warming up
appears on the control panel, and the scan head moves back and forth for 10 to 15 seconds. If you lift the lid, you
will see that the scanner bulb is lit. Near the end of this time, the ADF motor turns on for about 2 seconds.
Cause

Solution

No power is available because of a failed power source,
cable, switch, or fuse. (No LEDs are lit and the display is
blank.)

Verify that the product is plugged in to a functional power
source.

Verify that the power cable is functional and that the
power switch is on.

Verify that FU101 (FU102 for 110-volt units) on the ECU
is not open.

If all of these conditions are correct, replace the ECU.

Verify that the print cartridge is present.

Verify that the product doors are closed.

Verify that media is loaded in an input tray.

Verify that the printer paper-path sensors are functional.

Verify that the motor connector J402 is seated into the
ECU.

Verify that the motor is correctly mounted to the product
chassis.

If all of these conditions are correct, replace the ECU.

If, after replacing the ECU, the printer motor still does not
rotate, replace the motor.

Verify that the scanner connector is seated in both the
formatter and the motor controller board.

Check all the cabling on the motor controller board. Make
sure no cables are loose or damaged.

If the ADF motor still does not rotate, replace the ADF.

If the scanner bulb still does not turn on, replace the
scanner assembly.

If the problem persists, replace parts one at a time in the
following order until the problem is resolved: the motor
controller board, the formatter, and, finally, the ECU.

The printer motor does not rotate.

The ADF motor does not rotate, or the scanner bulb does not
turn on.

ENWW

Basic troubleshooting

161

Is the product ready?
The control panel should function without error messages.
Cause

Solution

An error message appears on the control-panel display.

Consult the list of common messages, which appears later in
this chapter, to correct the error. See Control-panel messages.

The control panel is not functional.

Verify that the control-panel cable is seated into both the
control panel and the motor controller board. Also check the
connections between the motor controller board and the
formatter. If all cables are undamaged and are seated
correctly, but the problem persists, replace the control panel.

The control-panel display is blank, but the LEDs are lit.

Print a page from a software program. If the page prints,
verify that the control-panel cables are correctly seated.

Recover the firmware by using the flash executable file or
the recovery DIMM. See Updating or recovering the
firmware code.

If the problem persists, replace the control panel.

If the problem persists, replace the motor controller
board.

If the problem persists, replace the formatter.

The control-panel display and LEDs function, but buttons do
not work.

Replace the control panel.

Squiggly lines appear on the control-panel display.

This is normal. If the problem persists, run a control-panel
check. See Control-panel check.

Do engine tests and self-tests print?
Print an engine test, which is explained in Engine test. The engine test should print without paper-feed problems or
print-quality problems. Also print a configuration report (see Troubleshooting tools).
Note: The formatter must be connected in order to perform an engine test.
Cause

Solution

The engine test is successful, but the configuration report
does not print.

Replace the formatter.

The engine test is not successful.

Replace the ECU.

An error message appears on the control-panel display.

Consult the list of common messages, which appears later in
this chapter, to correct the error. See Control-panel messages.

Media does not move smoothly through the printer paperpath.

Isolate printer paper-path problems by performing a paperpath check. See Paper-path check.

Documents print with poor print quality.

See Solving image-quality problems.

162

Chapter 6 Troubleshooting

ENWW

Is the copy function operational?
Place the configuration report into the ADF and make a copy. The report should feed smoothly through the ADF
and copies should print without print-quality problems. Also make a copy from the flatbed.
Cause

Solution

The flatbed produces poor-quality copies.

If the print quality from the internal tests and the copy from
the ADF are acceptable, clean the flatbed glass.

If, after performing the maintenance, the problem
persists, replace the scanner assembly.

If the print quality from the internal tests and the copy from
the flatbed are acceptable, clean the ADF scanner glass
or, if it is damaged, replace the glass.

If the problem persists, replace the scanner assembly.

The ADF produces poor-quality copies.

Media does not move smoothly through the ADF path.

Clean the ADF pick roller and ADF separation pad. If the
problem persists, replace the ADF pick roller and ADF
separation pad. If the problem persists, replace the ADF.

Does the product send a fax?
Connect the phone line and verify the dial tone (by using a hand set, if necessary). Attempt to send a fax.
Cause

Solution

The fax cord is plugged into the additional device connector
on the back of the product.

Verify that the fax cord is plugged into the fax interface port
(the bottom phone-cord connector) on the back of the
product.

The telephone line is not operational or the product is not
plugged into the telephone line.

Make sure that the product is plugged into a telephone line
that is known to work. Press FAX/SEND and listen for a dial
tone. Try a different line.

The phone cord is faulty or is plugged into the wrong
connector.

Try plugging the phone cord into the other connector on the
LIU. Try a new cord.

The product’s fax settings are set incorrectly.

Review and reset the product’s fax settings.

The flat flexible cable between the formatter and the LIU is
damaged or incorrectly seated.

Inspect, and reseat or replace the flat flexible cable between
the LIU and the formatter.

The LIU is not operational.

Replace the LIU. If the problem persists, replace the
formatter.

If the customer is using a digital subscriber line (DSL)
connection, the setup might be incorrect.

See Solving problems with digital subscriber line (DSL)
connections for information about setting up DSL
connections.

Control-panel messages
The majority of the control-panel messages are intended to guide the user through normal
operation. The control-panel messages indicate the status of the current operation, and
include a page count on the second line of the display, if appropriate. When the product is
receiving fax data, print data, or scanning commands, control-panel messages indicate this
status. In addition, alert messages, warning messages, and critical error messages indicate
situations that might require some action.
You must use the fax cord that came with the product in order to ensure that the product
functions correctly.

Note

Alert and warning messages
Alert and warning messages appear temporarily and might require the user to acknowledge
the message by pressing MENU/ENTER to resume or by pressing CANCEL to cancel the job. With
certain warnings, the job might not complete or the print quality might be affected. If the alert
or warning message is related to printing and the auto-continue feature is on, the product will
attempt to resume the printing job after the warning has appeared for 10 seconds without
acknowledgement.

If the problem occurs when copying or scanning, see Solving scanning (copying) image-quality
problems.
Also, see Solving print paper-feed problems and Jams occur in the automatic document
feeder (ADF).

Checking the print cartridge
Image-formation defects are frequently the result of problems in the print cartridge. If the
source of the defect is not immediately evident, always replace the print cartridge before
troubleshooting image defects.
Use the following checklist to make sure that the print cartridge is still operable.
□

Make sure that the print cartridge is seated properly.

□

Check the print cartridge to see if it has been disassembled or refilled.

□

Inspect the print cartridge to see if toner is leaking through worn seals.

□

Check the surface of the photosensitive drum in the cartridge to see if it has been
damaged or scratched. Touching the drum contaminates the photosensitive surface and
can cause spotting and image defects.

□

Blurred areas on printed pages indicate that the photosensitive drum in the cartridge has
been overexposed to light. Because overexposure to light causes permanent damage to
the photosensitive drum, the cartridge should be replaced.

To redistribute the toner in the print cartridge
Before installing a new print cartridge or when the toner begins to run low, redistribute the
toner by rotating the cartridge back and forth five or six times.

Solving print image-quality problems
Use the following tables to help solve problems with printed pages.

Solving problems with digital subscriber line (DSL) connections
A digital subscriber line (DSL) uses digital technology over standard copper phone wires. DSL
services rely on an AM signal. The HP LaserJet 3380 all-in-one is a Group 3 fax device, which
operates below the DSL capability and is not directly compatible with digital signals. However,
if specified during the DSL line setup, the signal on a DSL line can be separated so that some
of the bandwidth is used to transmit an analog signal (for voice and fax) while the remaining
bandwidth is used to transmit digital data. Split the signal to use both the telephone or fax and
the computer on the same line and at the same time.
Note

Not all printers and faxes are compatible with DSL services. HP does not guarantee that the
HP LaserJet all-in-one product will be compatible with all DSL service lines or providers.
The DSL modem requires a high-pass filter. Sometimes when DSL service is installed, the
service provider supplies a splitter, which includes a low-pass filter, for the normal house
phone wiring. If not, the user should contact the DSL provider, and request a filter or splitter to
enable a fax modem to operate on the line.

Note

204

HP recommends discussing DSL line setup options with the DSL service provider. Consult the
DSL provider for technical installation requirements.

ENWW

Connecting additional devices
Depending on how the phone lines are set up, additional devices can be connected to the
phone line along with the HP LaserJet 3380 all-in-one. In general, no more than three devices
should be connected to a single phone line. If too many devices are connected to a single
phone line, one or more of the devices might not detect an incoming call. If this occurs,
disconnect one or more of the devices.
Note

This product cannot replace a computer modem. It cannot act as a modem for sending and
receiving e-mail, for connecting to the Internet, or for communicating with other computers.

Dedicated fax line
If the product is connected to a phone line that is used only for fax calls, the following devices
can be connected:
●

Caller ID box

●

Modem—An internal or external computer modem can be connected to the fax line if the
fax line is to be used for e-mail or access to the Internet. However, faxes might not be
sent or received while the line is being used for these purposes.

●

Extra phone—An extra phone line can be connected to the fax line if the fax is to be used
for making outgoing calls.

Do not connect an answering machine or computer voicemail system to the fax line. If the
customer uses computer voicemail, connect the external or internal modem to the dedicated
phone line. Then, use the dedicated voice line to connect to the Internet and receive
voicemail.

Shared phone line
If the product is connected to a phone line that is shared between fax calls and voice calls, or
if the phone line has two phone numbers assigned and uses a ring-pattern service, the
following devices can be connected:

Note

●

Caller ID box

●

Phone—Connect a phone to the shared phone line to make or answer voice calls on the
shared line.

●

Answering machine or computer voicemail system—Connect these devices to the same
phone jack that the product uses in order to make sure that the different devices do not
interfere with one another.

It is possible to connect devices to another phone jack for the same phone line (for example,
in another room). However, the devices might interfere with faxing and with each other.

To connect additional devices
Connect additional devices in the order that is described in the following steps. The output
port for each device is connected to the input port of the next device, which forms a "chain."
Skip the steps for devices that the customer is not using, and continue to the next device.

ENWW

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

Engine test
The engine test is used to verify that the print engine is functioning correctly. The formatter is
bypassed during an engine test, so the engine test is useful for isolating printer problems. The
engine test prints horizontal lines down the entire printable area of a page and is also useful
for checking and adjusting registration.

Printing an engine test
The engine test switch is inside the left side door, below the formatter.
To print an engine test, open the left side door and use a non-conductive probe to depress the
engine test switch. A single test page will print.
CAUTION

Use a non-conductive probe to depress the engine test switch. Inserting a conductive probe to
depress the switch can damage the product.

Note

The formatter must be connected to the ECU in order to perform an engine test. Otherwise,
the printer does not print.
You must override the print cartridge door interlock (SW 301). (See Paper-path check.)

Figure 6-2.

Engine test switch

Control-panel check
Perform the control-panel check to verify that all the control-panel buttons and LEDs are
functioning. If any control-panel button or LED is not functioning, replace the control panel.

208

Chapter 6 Troubleshooting

ENWW

To perform the control-panel check
Note

Perform this procedure as quickly as possible in order to complete the control-panel check
before the formatter begins communicating with the control panel. The control-panel test
continues until all of the buttons have been tested or until the formatter attempts to
communicate with the control panel (after approximately 40 seconds). The control-panel test
will be interrupted if it is not completed before communication occurs.
1. Turn the product power on by using the power switch.
2. Immediately press the > and CANCEL buttons simultaneously.
3. Press and hold down the > and CANCEL buttons until the message Passed MEM Test
appears on the control-panel display.
4. Release the > and CANCEL buttons.
5. Press the MENU/ENTER button to test the control-panel display LEDs. Continue to press MENU/
ENTER until the message Scroll Check--Press Enter To Pass appears on the controlpanel display.
6. Press MENU/ENTER again.
7. The name of a control-panel button will appear on the control-panel display. Press the
corresponding button on the control panel. Repeat this step until all of the control-panel
buttons have been tested.

Note

The control-panel test continues until all of the buttons have been tested or there is no activity
at the control panel for about 20 seconds. After testing all of the control-panel buttons (or
when there is no activity at the control panel for about 20 seconds), the product exits the test
and continues the startup processes.

Half self-test functional check
The purpose of the half self-test check is to determine which image-formation process is
malfunctioning. The image-formation process can be subdivided into the following stages:
●

conditioning stage (charges the drum)

●

writing stage (writes a latent image to the drum with the laser)

●

development stage (forms a toner image on the drum)

●

transfer stage (transfers the image to paper)

●

separation stage (separates the media from the drum)

●

fusing stage (applies heat and pressure to make the image on paper permanent)

●

cleaning stage (removes excess toner from the drum)

To perform a half self-test check
1. Print a self-test page. (See Troubleshooting tools.)
2. Open the print cartridge door after the paper advances halfway through the printer (about 5
seconds after the motor begins rotation). The leading edge of the paper should have
advanced past the print cartridge.
3. Remove the print cartridge.

ENWW

Functional checks

209

4. Open the print cartridge drum shield to view the drum surface. If a dark and distinct toner
image is present on the drum surface, assume that the first three functions of the imageformation process are functioning (through the development stage). Troubleshoot the
failure as a transfer or fusing problem.

To perform other checks
If, during the half self-test check, no image is present on the photosensitive drum, perform
these checks:
1. Make sure that you removed the entire length of the sealing tape from the print cartridge
before you installed the cartridge.
2. Perform a drum-rotation functional check. (See Drum-rotation functional check .)
3. Perform a high-voltage power-supply check. (See High-voltage power-supply check.)

Drum-rotation functional check
The photosensitive drum, which is located in the print cartridge, must rotate in order for the
print process to work. The photosensitive drum receives its drive from the main drive
assembly.
Note

This test is especially important if refilled print cartridges have been used.
1. Open the print-cartridge door.
2. Remove the print cartridge.
3. Mark the drive gear on the cartridge with a felt-tipped marker. Note the position of the
mark.
4. Install the print cartridge and close the print-cartridge door. The startup sequence should
rotate the drum enough to move the mark.
5. Open the print-cartridge door and inspect the gear that was marked in step 3. Verify that
the mark moved.
If the mark did not move, inspect the main drive assembly to make sure that it is meshing with
the print-cartridge gears. If the drive gears appear functional and the drum does not move,
replace the print cartridge.

Heating-element check
Paper passes between the heating element and a soft pressure roller to fuse toner to the
paper.
1. Unplug the product for at least ten minutes. Remove the right cover (see Printer right-side
cover) and back cover (see Back cover).
2. Verify that the thermistor connector is seated into both the product chassis and the ECU.
3. Unplug the fuser cable connector (callout 1) by pressing and releasing the tab on the back
of the connector. To measure the continuity of the heating element, measure the
resistance between the two pins at the end of the cable.
Note

Normal resistance is 25 ohms +/- 10 ohms for the 110 V product and 80 ohms +/- 20 ohms for
the 220 V product.
If no resistance is measured, replace the fuser.

Updating or recovering the firmware code
The product has a flash-memory-based formatter that enables the firmware code to be
updated in the event that new firmware is released for the product. Using flash memory also
provides a way to recover the firmware in the event of code corruption or failure.

Firmware update by using flash executable
The configuration page lists the firmware version of the product. On flash-memory-based
products, you can update the firmware code by downloading the latest flash executable for the
product and running the program according to the readme instructions that come with it. Turn
the printer off and then on before running the executable file. If the firmware becomes
corrupted or fails (usually because of an interruption when attempting to update the firmware),
the product no longer functions. In this case, a firmware-recovery DIMM is available from HP.

Firmware-recovery DIMM
A firmware-recovery DIMM can be obtained from HP in the rare event that the firmware in
flash memory becomes corrupted. When the DIMM is installed in the DIMM slot on the
formatter and the product is turned on, the DIMM loads the latest firmware code into the
product.

To use the firmware-recovery DIMM
1. Order a firmware-recovery DIMM (RDIMM) from HP. Retain the return mailer.
2. Turn off the product.
3. Open the left-side door, and install the firmware-recovery DIMM into the DIMM slot
(callout 1).

To adjust fax data-store parameters
When you adjust fax data-store parameters, the product does not alert you to incorrect input
values. Changing fax data-store parameters can render the product illegal or inoperable.
Note

Before adjusting the fax data-store parameters, you can print a list of all the parameters from
the secondary service menu. See To print a list of all the Fax data-store parameters.
1. On the developer’s menu, use the < or > button to navigate to R/W PARAMETER, and
then press MENU/ENTER.
2. Use the < or > button to locate the parameter that you want to change. The current setting
appears on the control-panel display.
3. Type the new value for the fax data-store parameter, and then press MENU/ENTER.

To scroll quickly to a particular data-store parameter
When R/W PARAMETER appears on the control-panel display, jump directly to any
parameter ID that does not contain a 2 by typing the ID on the keypad. (Pressing 2 brings up
the secondary service menu.) To change a parameter that has a 2 in its ID, type the ID of the
closest parameter that does not have a 2 and then use the < or > button to locate the
parameter that you want to change. For example, to move quickly to parameter 152, enter 151 >.

Adjusting the country/region code parameters
Three situations can occur that necessitate changing the country/region or language settings
for the product:
1. The customer has moved to a different country/region from where the product was
purchased.
2. The information has been erased because of an NVRAM initialization.
3. The formatter was replaced.
Use the information in the following sections to adjust the country/region and language
settings.

To change the country/region from one location to another
1. Press MENU/ENTER, and then press 2 to gain access to the Secondary Service menu.
2. Press < or > to select Location, and then press MENU/ENTER.
3. Press < or > until the correct location appears.
4. When the correct location appears, press MENU/ENTER. Press 1 to confirm the new location.
The product automatically turns itself off and then on after the setting is confirmed.

To set the language and location if none is set
If the language and location settings have been erased because NVRAM has been initialized,
or if the formatter has been replaced, the product automatically prompts for the language and
the location when it is turned on.

240

Chapter 6 Troubleshooting

ENWW

Note

The customer cannot send or receive faxes until these settings have been established.
1. Press < or > until the correct language appears.
2. When the correct language appears, press MENU/ENTER, and then press 1 to confirm the
selection.
3. Press < or > until the correct country/region appears.

Note

The list of countries/regions that appears on the control-panel display depends on the LIU that
is installed in the product.
4. When the correct country/region appears, press MENU/ENTER, and then press 1 to confirm
the selection.
5. After both the language and the location settings are established, the product
automatically turns itself off and then on.

Soft reset
Before performing an NVRAM init, attempt a soft reset, which does not reset configuration
settings or cause loss of data.

To perform a soft reset
1. Press MENU/ENTER.
2. Simultaneously press then release the * button and the # button to enter the Developer's
menu.
3. Press the < or > button until the message REINIT FFS appears on the second line of the
control-panel display.
4. Press MENU/ENTER.
5. The process takes approximately 2.5 minutes. During that time, the control-panel display
will change several times before returning to Ready.
6. When the Ready message appears on the control-panel display, press CANCEL to exit the
Developer's menu.

NVRAM init
NVRAM init returns all stored parameters in NVRAM to factory default values or to a default
ROM value, depending on the variable, and performs a system reset.
Performing NVRAM init can cause the product to violate local telephone regulations. Reset the
language and country/region after performing NVRAM init.
NVRAM init resets the following settings and information:

ENWW

●

All menu settings are reset to factory default values, including fax header and company
name.

●

Factory settings such as formatter number, page counts, and factory paper settings are
reset.

●

All faxes in memory are erased.

●

All speed-dials, group-dials, and phone book entries are erased.

●

All localization settings, including language and country/region, are reset.

Service-mode functions

241

To perform NVRAM init
1. Turn off the product.
2. Press and hold down the * and MENU/ENTER buttons.
3. Continue to hold down the buttons while you turn on the product. Hold the buttons through
the entire power-on sequence.
4. When Permanent Storage Init. appears on the control-panel display, release the
buttons.
5. When the message Language appears on the control-panel display, set the correct
language and country/region.
6. Allow the product to return to Ready before using the product.

Printer job language (PJL) software commands
Many PJL scripts are available for restoring parameters such as paper size and page counts
after the formatter has been replaced. For comprehensive instructions, see the Printer Job
Language Technical Manual and the Printer Job Language Technical Manual Addendum.
