The average cartridge yield is 6,500 pages (for the Q7551A cartridge) or 13,000 pages (for the Q7551X
cartridge), in accordance with ISO/IEC 19752. Actual cartridge yield depends on specific use.
CAUTION The Economode feature allows the device to use less toner per page. Selecting
Economode extends the life of the toner supply and reduces the cost per page but reduces print
quality. The printed image is lighter but is adequate for printing drafts or proofs. Hewlett-Packard
does not recommend full-time use of Economode. If Economode is used full-time, the toner
supply might outlast the mechanical parts in the print cartridge. If print quality begins to degrade
under these circumstances, install a new print cartridge even if the print cartridge still contains
toner.

ENWW

Manage the print cartridge
Print-cartridge storage
Do not remove the print cartridge from its package until you are ready to use it.
CAUTION To prevent damage to the print cartridge, do not expose it to light for more than a
few minutes.

Use genuine HP print cartridges
When you use a genuine new HP print cartridge, you can obtain the following supplies information:
●

Percentage of supplies remaining

●

Estimated number of pages remaining

●

Number of pages printed

HP policy on non-HP print cartridges
Hewlett-Packard Company cannot recommend the use of non-HP print cartridges, either new or
remanufactured. Because they are not HP products, HP cannot influence their design or control their
quality.
NOTE Any damage caused by a non-HP print cartridge is not covered under the HP warranty
and service agreements.
To install a new HP print cartridge, see Change the print cartridge on page 27. To recycle the used
cartridge, follow the instructions included with the new cartridge.

Print-cartridge authentication
The device automatically authenticates the print cartridge when it is inserted into the device. During
authentication, the device notifies you whether a cartridge is a genuine HP print cartridge.
If the device control-panel message states that this is not a genuine HP print cartridge and you believe
you purchased an HP print cartridge, see HP fraud hotline and Web site on page 39.

HP fraud hotline and Web site
Call the HP fraud hotline (1-877-219-3183, toll-free in North America) or go to www.hp.com/go/
anticounterfeit when you install an HP print cartridge and the control-panel message says the cartridge
is non-HP. HP will help determine if the cartridge is genuine and take steps to resolve the problem.
Your print cartridge might not be a genuine HP print cartridge if you notice the following:

ENWW

●

You are experiencing a high number of problems with the print cartridge.

●

The cartridge does not look like it usually does (for example, the orange pull tab is missing, or the
packaging differs from HP packaging).

Manage supplies

Clean the device
Over time, particles of toner and paper accumulate inside the device. This can cause print-quality
problems during printing. Cleaning the device eliminates or reduces these problems.
Clean the paper path and print-cartridge areas every time that you change the print cartridge or
whenever print-quality problems occur. As much as possible, keep the device from dust and debris.

Clean the exterior
Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off of the exterior of the device.

Clean the ADF
If the ADF has trouble feeding documents, clean the ADF pickup roller assembly.

Turn off the device and unplug the power cord.

Open the ADF cover.

Press the round blue button while lifting the green lever. Rotate the green lever until it stops in the
open position. The pickup roller assembly should remain on the surface.

Chapter 3 Maintenance

ENWW

Remove the assembly, and then wipe the assembly with a soft, dry, lint-free cloth.

Replace the assembly, with the largest roller down, in the upright holder, and then press until the
assembly snaps into place.

Make sure that both sides of the assembly are secured by the blue hooks.

Lower the roller assembly, and then close the ADF cover.

Clean the device

Plug in the device, and then turn on the device.

Clean the scanner lid backing
Minor debris can accumulate on the white document lid backing that is located underneath the scanner
lid.
1.

Open the scanner lid.

Clean the white document lid backing by using a soft cloth or sponge that has been moistened with
a mild soap and warm water.

Wash the backing gently to loosen debris; do not scrub the backing.

Dry the backing by using a chamois or soft cloth.
CAUTION Do not use paper-based wipes because they might scratch the backing.

If this does not clean the backing well enough, repeat the previous steps and use isopropyl alcohol
to dampen the cloth or sponge, and then wipe the backing thoroughly with a damp cloth to remove
any residual alcohol.

Chapter 3 Maintenance

ENWW

Clean the scanner glass
Dirty glass, from fingerprints, smudges, hair, and so on, slows down performance and affects the
accuracy of special features such as fit-to-page and copy.
NOTE If streaks or other defects appear only on copies produced using the automatic document
feeder (ADF), clean the scanner strip (step 3). It is not necessary to clean the scanner glass.
1.

Open the scanner lid.

Clean the glass by using a damp, lint-free cloth.

CAUTION Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon
tetrachloride on any part of the device; these can damage the device. Do not place liquids
directly on the glass. They might seep under it and damage the device.
3.

ENWW

Clean the scanner strip by using a damp, lint-free cloth.

Clean the device

Clean the fuser
Run the device cleaning page to keep the fuser free of toner and paper particles that can sometimes
accumulate. Accumulation of toner and particles can cause specks to appear on the front or back side
of your print jobs.
To ensure optimum print quality, HP recommends that you use the cleaning page every time that you
replace the print cartridge.
The cleaning procedure takes about 2.5 minutes to complete. A CLEANING message appears on the
device control panel display while the cleaning is taking place.
In order for the cleaning page to work correctly, print the page on copier-grade paper (not bond, heavy,
or rough paper).

ADF/scanner system
ADF
If the ADF fails, it can be replaced as a whole-unit replacement part.
Sensors in the ADF
The ADF contains the following sensors:
●

ADF-cover sensor. Detects whether the ADF cover is open or closed.

●

Top-of-page sensor. Detects the top of the page before sending a page through the ADF and the
end of the page after feeding/scanning is complete.

●

Paper-present sensor. Detects whether a document is present in the ADF. If paper is present in
the ADF when copies are made, the device scans the document using the ADF. If no paper is
present when copies are made, the device scans the document using the scanner glass.

ADF paper path
The ADF feeds documents past the ADF glass for scanning. Figure 4-2 ADF path for single-sided

Dc and ac biases are applied to the primary charging roller, which transfers a uniform negative potential
to the photosensitive drum.

Figure 4-12 Primary charging

Step 2: Laser beam exposure
The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum. An
electrostatic latent image is formed on the drum where negative charges were neutralized.

Step 3: Developing
The developing cylinder comes in contact with the photosensitive drum to deposit toner onto the
electrostatic latent image.
NOTE The charges on the exposed area of the drum are shown as positive in Figure 4-13
Developing on page 65. The charges are actually negative, but they are more positive than the
charges on the developing cylinder.

Figure 4-13 Developing

ENWW

Basic operation

Toner acquires a negative charge through friction from the developing cylinder and the blade. When the
negatively charged toner comes in contact with the drum, the toner adheres to the electrostatic latent
image. The image on the drum becomes visible because of the toner.

Step 4: Transfer
The transfer charging roller, to which a dc positive bias is applied, imparts a positive charge on the print
media. When the print media comes in contact with the photosensitive drum, the toner is transferred to
the print media.

Figure 4-14 Transfer

Step 5: Separation
The elasticity of the print media causes its separation from the photosensitive drum. A static charge
eliminator aids separation by weakening any electrostatic adhesion.

Figure 4-15 Separation

Chapter 4 Theory of operation

ENWW

Step 6: Fusing
The dc negative bias applied to the fusing film strengthens the holding force of the toner on the print
media and prevents the toner from scattering.

Figure 4-16 Fusing

Step 7: Drum cleaning
The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the
waste toner case.

information about device timing.

STBY (standby)

From the end of the WAIT or LSTR period until either
a print command is sent from the formatter or the
power is turned off.

Prepares the device to receive print commands

INTR (initial
rotation)

From the time of the print command until the pickup
solenoid is turned on.

Prepares the photosensitive drum for printing.

From the end of the INTR period until the top-of-page
sensor detects the trailing edge of the media.

Forms the image on the photosensitive drum and
transfers the toner image to the media.

LSTR (last
rotation)

From the end of the PRINT period until the main
motor stops rotating.

Delivers the last page of a print job.
After LSTR, the device either returns to STBY or, if
another print command was sent from the formatter,
enters INTR.

ENWW

Print cartridge memory system
The memory tag is a nonvolatile memory built into the print cartridge. The cartridge usage condition is
detected as the engine controller reads or writes the data stored on the memory tag. The engine
controller renews the information in the prescribed timing and reads or writes it from or to the memory
tag.
The engine controller commands the memory tag to read or write with the following conditions:
●

●

Read
●

Power is ON

●

The top cover is closed

●

A command has been received from the formatter

Write
●

A page of media is printed.

●

A command has been received from the formatter

When the engine controller failed to read or write three times in a row, it determines that the memory
tag is abnormal and notifies the formatter of a "cartridge memory abnormality warning".

Stapler testing – to be performed after the device is fully reassembled
WARNING! Incorrect reinstallation of the stapler can cause the stapler-door switch to operate
incorrectly, resulting in a safety hazard. Test the stapler for correct operation before releasing
the device back to the customer.
Final stapler-test procedure
Test #1: Does the stapler operate correctly when the stapler door is closed?
With the stapler door closed, use the stapler to staple several sheets of paper together. The stapler
should staple the sheets.
Test #2 (safety-switch test): Does the stapler operate when the stapler door is open?
Open the stapler door and attempt to use the stapler to staple several sheets of paper together. When
the stapler and stapler door safety-switch are operating correctly, the open door cuts power to the stapler
and the stapler does not staple the sheets.

ENWW

Stapler 121

WARNING! Do not release the device back to the customer unless the stapler passes both of
the tests. If the stapler fails either test, remove the stapler and then reinstall it by carefully following
the installation steps shown in this manual. If the stapler continues to fail one or both tests, replace
the stapler and the stapler power supply.
If the staple activates when the stapler door is open, and the stapler cannot be repaired without
ordering parts, disconnect the stapler power supply before reassembling the device and before
you leave the customer site. When the stapler power supply is disconnected, the customer can
safely operate all device functions, except for stapling, while waiting for repair of the stapler.

Control-panel messages
Control-panel message types
Four types of control-panel messages can indicate the status of or problems with the device.
Message type

Description

Status messages

Status messages reflect the current state of the device. They inform you of normal device operation
and require no interaction to clear them. They change as the state of the device changes. Whenever
the device is ready, not busy, and has no pending warning messages, the status message Ready
appears if the device is online.

Warning messages

Warning messages inform you of data and print errors. These messages typically alternate with
the Ready or status messages and remain until you touch OK. Some warning messages are clearable.
If Clearable Warnings is set to Job on the device Device Behavior menu, the next print job clears
these messages.

Error messages

Error messages communicate that some action must be performed, such as adding paper or clearing
a jam.
Some error messages are auto-continuable. If Auto Continue is set on the menus, the device will
continue normal operation after an auto-continuable error message appears for 10 seconds.
NOTE Pressing any button during the 10-second auto-continuable error message overrides
the auto-continue feature, and the button function takes precedence. For example, pressing
the Stop button pauses printing and offers the option to cancel the print job.

Critical-error messages

Critical error messages inform you of a device failure. Some of these messages can be cleared by
turning the device off and then on. These messages are not affected by the Auto Continue setting.
If a critical error persists, service is required.

PS901

Top-of-page sensor

SR2

Delivery sensor

Duplex sensor

The CPU on the ECU identifies jams by checking whether media is present during the printing process
against media-transport timing, which is stored in memory. When the CPU determines that a jam has
occurred, it stops the printing operation and sends a signal to the formatter so that the touchscreen can
show an error message.
The CPU determines a residual-media jam if one or more of the sensors PS901, SR2, PS502, or
PS903 detects that media is present after power-on or when an open door (for example, the cartridge
door) is shut.
The CPU determines a delivery-delay jam if PS4 does not detect the leading edge of the media within
a specified time after PS901 detects the leading edge.

NOTE Before performing a hard-disk initialization, print a configuration page (see Use
information pages on page 45). Use the information on the configuration page to reset any
customer-set device configuration values that the hard-disk initialization procedure
changes.

●

Skip disk-load. When the power is turned on the device begins the power-on sequence. By
performing a skip disk-load, you can cause the device to resume the power-on sequence but not
to recognize the hard disk. This can be helpful in isolating hard-disk errors.

●

NVRAM init.
CAUTION Initializing the NVRAM resets the event log, the page counts, and embedded
EIO and resets service menu values to factory defaults. NVRAM initialization does not reset
the model number, serial number, service ID (born-on date), usage data, or the error log.
Use the service menu to restore the serial number and page counts. Also reconfigure any
computers that print to this device so that the computers can recognize the device. Initialize
the NVRAM only when absolutely necessary. In most situations, use a cold reset rather than
a NVRAM initialization to reset device settings and retain the values in the service menu.
NOTE Before performing a NVRAM initialization, print a configuration page (see Use
information pages on page 45). Use the information on the configuration page to reset any
customer-set device configuration values that the NVRAM initialization procedure changes.
Take special note of the total page count, maintenance count, and the serial number.

Service ID
This information appears on the configuration page (see Use information pages on page 45), which
eliminates the need for customers to keep paper receipts for proof of the warranty. Because the device
does not have an internal clock, the availability of the service ID date depends on the device being
connected to a source that can provide the date, in this case a time server on the same network as the
device. When the device is not connected to a date source, the service ID is not available, and 00000
appears on the configuration page.

228 Chapter 6 Troubleshooting

ENWW

Restore the service ID
If you replace the formatter, the service ID is lost. Use this menu item to reset the value to the date that
the device was first used. The date format is YYDDD. Use the following procedure to calculate the date.
1.

To calculate YY, subtract 1990 from the calendar year. For instance, if the device was first used in
2002, calculate YY as follows: 2002 - 1990 = 12 (YY = 12).

To calculate DDD, use the following formula: 30 (calendar month - 1) + calendar day = DDD. If the
calendar day is 31, use 30 instead. For instance, if the printer was first used on October 17,
calculate DDD as follows:
a.

Subtract 1 from 10 (October is the tenth month of the year): 10 - 1 = 9.

Multiply 9 by 30: 9 x 30 = 270.

Add 17 to 270: 270 + 17 = 287 (DDD = 287).

Convert the service ID to an actual date
You can use the device service ID number to determine whether the device 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 device was installed.

Divide DDD by 30 and add 1 to the remainder. 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:
●

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.

A six-day grace period is built into the date system.

To verify that the device engine is functioning, print an engine-test page. To print an engine-test page,
press the engine-test-page switch (callout 1).

Figure 6-3 Locating the engine-test-page switch
The test page should have a series of horizontal lines. The test page prints from the last tray that the
device pulled from, unless the device has been turned off and then turned on again since the most recent
print job. If the device has been turned off and then on again since the most recent print job, then the
page will print from tray 2. The device will continuously print test pages until the test-page switch is
released. The device will not 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

Firmware updates and recovery
The device uses a flash-memory-based formatter that enables the firmware code to be updated when
updated firmware is available. Flash memory also provides a method for product recovery if the installed
firmware becomes corrupted or fails.
The device has remote firmware update (RFU) capability. Use the information in this section to upgrade
the firmware. The overall process involves the following steps:
1.

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

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 your computer.

Transfer the new firmware from your computer to the device.
NOTE If after attempting to update the firmware code the device does not return to the
Ready state, perform the following procedures:
Try the firmware update again.
Perform the NVRAM init procedure. See Service mode functions on page 226.
If the device still does not reach the Ready state, replace the formatter. See Formatter
on page 116.

Determine the current level of firmware
The current level of firmware is shown on the configuration page. To print a configuration page, touch
Administration, touch Configuration/Status Pages, touch Configuration Page, and then touch Print.
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 that
begins with 20040225 represents February 25, 2004.

Download the new firmware from the HP Web site
To find the most recent firmware upgrade for the device, go to www.hp.com/support/LJM3027mfp or
www.hp.com/support/LJM3035mfp. This page provides instructions for downloading the new firmware
version.

ENWW

Firmware updates and recovery 239

Transfer the new firmware to the device
Use one of the following methods to update the firmware.

Use FTP to upgrade the firmware on a network connection
NOTE

The device 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
device 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 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.
1.

Take note of the IP address on the HP Jetdirect page. The HP Jetdirect page is the second page
that prints when you print the configuration page.
NOTE Before upgrading the firmware, make sure that the device is not in Sleep mode.
Also make sure that any error messages are cleared from the control-panel display.

Troubleshoot media-handling problems 247

Troubleshoot print-quality problems
This section helps you define print-quality problems and what to do to correct them. Often print-quality
problems can be handled easily by making sure that the device is correctly maintained, using print media
that meets HP specifications, or running a cleaning page.

Print-quality checklist
Follow the checklist to solve general print-quality problems.
●

Process a cleaning page to clean the fuser (see Clean the fuser on page 44).

●

Check the printer driver to make sure that you are using the best available print-quality option (see
the user guide).

●

Try printing with one of the alternative printer drivers. The most recent printer drivers area available
for download from www.hp.com/go/LJM3027mfp_software or www.hp.com/go/
LJM3035mfp_software.

●

Clean the inside of the device (see Clean the device on page 40).

●

Check the paper type and quality (see Media specifications on page 15).

●

Check to make sure that Economode is off in the software.

●

Troubleshoot general printing problems (see Troubleshoot general printing problems
on page 243).

●

Install a new HP print cartridge, and then check the print quality again. (See the instructions
provided with the print cartridge.)
NOTE If the page is totally blank, check to make sure that the sealing tape is removed from the
print cartridge and that the print cartridge is installed correctly. Newer devices have been
optimized to print characters more accurately. This might result in characters that look lighter or
thinner than you are used to from an older device. If the page is printing images darker than those
from an older device, and you want the images to match the older device, make these changes
in the printer driver: on the Finishing tab, select Print Quality, select Custom, click Details, and
select Print Images Lighter.

HP PRODUCT

DURATION OF LIMITED WARRANTY

HP LaserJet M3027, M3027x, M3035, and M3035xs

One-year on-site warranty

HP warrants to you, the end-user customer, that HP hardware and accessories will be free from defects in materials
and workmanship after the date of purchase, for the period specified above. If HP receives notice of such defects
during the warranty period, HP will, at its option, either repair or replace products which prove to be defective.
Replacement products may be either new or equivalent in performance to new.
HP warrants to you that HP software will not fail to execute its programming instructions after the date of purchase,
for the period specified above, due to defects in material and workmanship when properly installed and used. If
HP receives notice of such defects during the warranty period, HP will replace software which does not execute
its programming instructions due to such defects.
HP does not warrant that the operation of HP products will be uninterrupted or error free. If HP is unable, within a
reasonable time, to repair or replace any product to a condition as warranted, you will be entitled to a refund of
the purchase price upon prompt return of the product.
HP products may contain remanufactured parts equivalent to new in performance or may have been subject to
incidental use.
Warranty does not apply to defects resulting from (a) improper or inadequate maintenance or calibration, (b)
software, interfacing, parts or supplies not supplied by HP, (c) unauthorized modification or misuse, (d) operation
outside of the published environmental specifications for the product, or (e) improper site preparation or
maintenance.
TO THE EXTENT ALLOWED BY LOCAL LAW, THE ABOVE WARRANTIES ARE EXCLUSIVE AND NO OTHER
WARRANTY OR CONDITION, WHETHER WRITTEN OR ORAL, IS EXPRESSED OR IMPLIED AND HP
SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY,
SATISFACTORY QUALITY, AND FITNESS FOR A PARTICULAR PURPOSE. Some countries/regions, states or
provinces do not allow limitations on the duration of an implied warranty, so the above limitation or exclusion might
not apply to you. This warranty gives you specific legal rights and you might also have other rights that vary from
country/region to country/region, state to state, or province to province. HP's limited warranty is valid in any country/
region or locality where HP has a support presence for this product and where HP has marketed this product. The
level of warranty service you receive may vary according to local standards. HP will not alter form, fit or function
of the product to make it operate in a country/region for which it was never intended to function for legal or regulatory
reasons.
TO THE EXTENT ALLOWED BY LOCAL LAW, THE REMEDIES IN THIS WARRANTY STATEMENT ARE YOUR
SOLE AND EXCLUSIVE REMEDIES. EXCEPT AS INDICATED ABOVE, IN NO EVENT WILL HP OR ITS
SUPPLIERS BE LIABLE FOR LOSS OF DATA OR FOR DIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL

ENWW

(INCLUDING LOST PROFIT OR DATA), OR OTHER DAMAGE, WHETHER BASED IN CONTRACT, TORT, OR
OTHERWISE. Some countries/regions, states or provinces do not allow the exclusion or limitation of incidental or
consequential damages, so the above limitation or exclusion may not apply to you.
THE WARRANTY TERMS CONTAINED IN THIS STATEMENT, EXCEPT TO THE EXTENT LAWFULLY
PERMITTED, DO NOT EXCLUDE, RESTRICT OR MODIFY AND ARE IN ADDITION TO THE MANDATORY
STATUTORY RIGHTS APPLICABLE TO THE SALE OF THIS PRODUCT TO YOU.

Customer self repair warranty service
HP products are designed with many Customer Self Repair (CSR) parts to minimize repair time and
allow for greater flexibility in performing defective parts replacement. If during the diagnosis period, HP
identifies that the repair can be accomplished by the use of a CSR part, HP will ship that part directly to
you for replacement. There are two categories of CSR parts: 1) Parts for which customer self repair is
mandatory. If you request HP to replace these parts, you will be charged for the travel and labor costs
of this service. 2) Parts for which customer self repair is optional. These parts are also designed for
Customer Self Repair. If, however, you require that HP replace them for you, this may be done at no
additional charge under the type of warranty service designated for your product.
Based on availability and where geography permits, CSR parts will be shipped for next business day
delivery. Same-day or four-hour delivery may be offered at an additional charge where geography
permits. If assistance is required, you can call the HP Technical Support Center and a technician will
help you over the phone. HP specifies in the materials shipped with a replacement CSR part whether
a defective part must be returned to HP. In cases where it is required to return the defective part to HP,
you must ship the defective part back to HP within a defined period of time, normally five (5) business
days. The defective part must be returned with the associated documentation in the provided shipping
material. Failure to return the defective part may result in HP billing you for the replacement. With a
customer self repair, HP will pay all shipping and part return costs and determine the courier/carrier to
be used.

Print cartridge limited warranty statement
This HP product is warranted to be free from defects in materials and workmanship.
This warranty does not apply to products that (a) have been refilled, refurbished, remanufactured or
tampered with in any way, (b) experience problems resulting from misuse, improper storage, or
operation outside of the published environmental specifications for the device product or (c) exhibit wear
from ordinary use.
To obtain warranty service, please return the product to place of purchase (with a written description of
the problem and print samples) or contact HP customer support. At HP's option, HP will either replace
products that prove to be defective or refund your purchase price.
TO THE EXTENT ALLOWED BY LOCAL LAW, THE ABOVE WARRANTY IS EXCLUSIVE AND NO
OTHER WARRANTY OR CONDITION, WHETHER WRITTEN OR ORAL, IS EXPRESSED OR
IMPLIED AND HP SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTIES OR CONDITIONS OF
MERCHANTABILITY, SATISFACTORY QUALITY, AND FITNESS FOR A PARTICULAR PURPOSE.
TO THE EXTENT ALLOWED BY LOCAL LAW, IN NO EVENT WILL HP OR ITS SUPPLIERS BE
LIABLE FOR DIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL (INCLUDING LOST PROFIT OR
DATA), OR OTHER DAMAGE, WHETHER BASED IN CONTRACT, TORT, OR OTHERWISE.

HP maintenance agreements
HP has several types of maintenance agreements that meet a wide range of support needs.
Maintenance agreements are not part of the standard warranty. Support services may vary by area.
Check with your local HP dealer to determine the services available to you.

On-site service agreements
To provide you with the level of support best suited to your needs, HP has on-site service agreements
with a selection of response times.

Next-day on-site service
This agreement provides support by the next working day following a service request. Extended
coverage hours and extended travel beyond HP’s designated service zones are available on most onsite agreements (for additional charges).

Weekly (volume) on-site service
This agreement provides scheduled weekly on-site visits for organizations with many HP products. This
agreement is designated for sites using 25 or more workstation products, including devices, plotters,
computers, and disk drives.

Repacking the device
If HP Customer Care determines that your device needs to be returned to HP for repair, follow the steps
below to repack the device before shipping it.
CAUTION Shipping damage as a result of inadequate packing is the customer’s responsibility.
To repack the device
1.

Remove and retain any DIMMs cards that you have purchased and installed in the device. Do not
remove the DIMM that came with the device.
CAUTION Static electricity can damage DIMMs. When handling DIMMs, either wear an
antistatic wrist strap, or frequently touch the surface of the DIMM antistatic package and
then touch bare metal on the device. To remove the DIMMs, see Install memory
on page 30.

Remove and retain the print cartridge.
CAUTION It is extremely important to remove the print cartridge before shipping the
device. A print cartridge that remains in the device during shipping will leak and entirely
cover the device engine and other parts with toner.
To prevent damage to the print cartridge, avoid touching the roller on it, and store the print
cartridge in its original packing material or so that it is not exposed to light.

Remove and retain the power cable, interface cable, and optional accessories.

324 Appendix B Service and support

ENWW

If possible, include print samples and 50 to 100 sheets of paper or other print media that did not

Safety statements
Laser safety
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration has
implemented regulations for laser products manufactured since August 1, 1976. Compliance is
mandatory for products marketed in the United States. The device is certified as a “Class 1” laser product
under the U.S. Department of Health and Human Services (DHHS) Radiation Performance Standard
according to the Radiation Control for Health and Safety Act of 1968. Since radiation emitted inside the
device is completely confined within protective housings and external covers, the laser beam cannot
escape during any phase of normal user operation.
WARNING! Using controls, making adjustments, or performing procedures other than those
specified in this user guide may result in exposure to hazardous radiation.

Canadian DOC regulations
Complies with Canadian EMC Class B requirements.
« Conforme à la classe B des normes canadiennes de compatibilité électromagnétiques. « CEM ». »

Working with memory and print server
cards

This section explains the device memory features and provides steps for expansion.
●

ENWW

Overview

341

Overview
One dual inline memory module (DIMM) slot is available for upgrading the device with the following
items:
●

More memory—DIMMs are available in 64, 128, 256, and 512 MB.

●

Other DIMM-based printer languages and printer options.

The device uses 100-pin 133 MHz DDR memory modules. Extended data output (EDO) DIMMs are not
supported.
For ordering information, see Order parts, accessories, and supplies on page 314.
NOTE Single inline memory modules (SIMMs) used in previous HP LaserJet printers are not
compatible with the device.
The device also has one EIO slot for expanding the device networking capabilities. The EIO slot can be
used to upgrade the device with an additional network connection, such as a wireless print server,
network card, or a connectivity card for a serial or AppleTalk connection.
To find out how much memory is installed in the device, or to find out what is installed in the EIO slots,
print a configuration page. See Use information pages on page 45.
NOTE If memory problems occur when you are printing complex graphics, you can make more
memory available by removing downloaded fonts, style sheets, and macros from device memory.
Reducing the complexity of a print job from within a program can help avoid memory problems.
