Tray 1
Tray 1 is accessed from the front of the product. The product prints from Tray 1 before trying to print
from other trays.
Media guides ensure that the media is correctly fed into the product and that the print is not skewed
(crooked on the media). When loading media, adjust the media guides to match the width of the media
that you are using.

Tray 2
Media guides ensure that the media feeds correctly into the product and that the print is not skewed.
Tray 2 has side and rear media guides. When loading media, adjust the media guides to match the
length and width of the media that you are using.
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 reduces jams by preventing multiple sheets of media from
feeding through the product at one time.
Load A6-size paper
When loading A6-size paper, adjust the length by sliding forward only the center panel of the rear media
guide.

Use paper output options
The product has two output locations: the top (standard) output bin and the straight-through paper path
(rear output).
Print to the top (standard) output bin
The top output bin collects paper face-down, in the correct order. The top output bin should be used for
most print jobs, including transparencies. To use the top output bin, be sure that the rear output (straight-
through paper path) is closed. To avoid jams, do not open or close the rear output while the product is
printing.
44 Chapter 3 Paper and print media ENWW
Print to the straight-through paper path (rear output)
The product always uses the straight-through paper path if it is open. Paper exits face-up, with the last
page on top (reverse order).
Printing from Tray 1 to the rear output provides the straightest path. Opening the straight-through paper
path might improve performance with the following paper types:
●Envelopes
●Labels
●Small custom-size paper
●Postcards
●Paper heavier than 120 g/m

Print quality
Use the HP ToolboxFX print-quality options to improve the appearance of print jobs. These are the same
options that are available on the product control panel. For more information, see Control panel (HP
LaserJet P2050 Series Printers only) on page 22.
The four options provided for controlling print quality are resolution, REt (Resolution Enhancement
technology), print density, and EconoMode.
●Resolution. Select 600 resolution for average print jobs and FastRes 1200 for higher-quality print
jobs. Select ProRes 1200 for the highest-quality print job, but a longer printing time.
●REt. You can turn on REt, which HP provides for improved print quality.
54 Chapter 4 Manage and maintain ENWW
●Print density. For increased print density, select a higher number. For decreased print density,
select a lower number.
●EconoMode. Turn EconoMode on when you are printing average print jobs. EconoMode is a
feature that allows the product to use less toner per page. Selecting this option might extend the
life of the toner supply and might reduce cost per page. However, it reduces print quality. The
printed image is lighter, but it is adequate for printing drafts or proofs. HP does not recommend
full-time use of EconoMode. If EconoMode is used full-time, it is possible that the toner supply can
outlast the mechanical parts in the print cartridge. If print quality begins to degrade under these
circumstances, install a new print cartridge, even if there is toner supply remaining in the cartridge.
NOTE: You must click Apply before the changes take effect.
Paper Types
Use these options to configure print modes that correspond to the various media types. To reset all
modes to factory defaults, select Restore modes.
NOTE: You must click Apply before your changes take effect.
System Setup
Use these system settings to configure miscellaneous print settings. These settings are not available
on the control panel.
NOTE: You must click Apply before your changes take effect.
Troubleshooting
During the printing process, paper, toner and dust particles can accumulate inside the product. Over
time, this buildup can cause print-quality problems such as toner specks or smearing. The HP ToolboxFX
provides an easy method for cleaning the paper path. For more information, see Clean the paper path

Timing
Sequence of operation
The microprocessor on the DC controller controls the product operation sequences.
Table 5-1 Sequence of operation
Name Timing Purpose
WAIT From power-on or the door is closed until the end of
the main motor initial drive.
Detects presence of a print cartridge.
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 product to receive print commands
INTR (initial
rotation)
From the time the print command is received from the
formatter until the fuser reached its targeted
temperature.
Starts each high-voltage biases, the laser scanner,
and fuser in preparation for printing.
PRINT From the end of the INTR period until the last media
completes the fusing operation.
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 (when high-voltage
is turned off) until the main motor stops rotating.
Delivers the last page of a print job.
After LSTR, the product either returns to STBY or, if
another print command was sent from the formatter,
enters INTR.

DC controller identifies the laser/scanner unit failure and notifies the formatter if the laser/scanner unit
encounters the following conditions:
●Scanner motor failure
●BD failure
ENWW Laser/scanner system 89
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 product processes. Image formation consists of the following five processes:
●electrostatic latent-image formation
●developing
●transfer
●fusing
●drum cleaning
The five processes contain seven steps.

DC and AC biases are applied to the primary charging roller, which transfers a uniform negative potential
to the photosensitive drum.
Figure 5-9 Primary charging
Primary charging bias
Photosensitive drum

90 Chapter 5 Theory of operation ENWW
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.
Laser beam
Unexposed area Exposed area
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 5-10 Developing
on page 91. The charges are actually negative, but they are more positive than the charges on the
developing cylinder.
Figure 5-10 Developing
Developing bias
Blade

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.
ENWW Image-formation system 91

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.

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.

Pickup/feed/delivery system
The pickup/feed/delivery system consists of several types of feed rollers and sensors. The DC controller
uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as
it passes through the product. If media does not reach or pass each sensor within a specified period,
the DC controller determines that a jam has occurred and alerts the formatter.

Introduction
This chapter describes the removal and replacement of field-replaceable units (FRUs) only.
NOTE: Your product might not appear exactly as the one shown in the photos in this chapter. For
example, the color of the external panels and covers might be different than your product. However, the
procedures in this chapter are valid for both the HP LaserJet P2035 and the HP LaserJet P2055.
Replacing FRUs is generally the reverse of removal. Notes and tips are included to provide directions
for difficult or critical replacement procedures.
HP does not support repairing individual subassemblies or troubleshooting to the component level.
Note the length, diameter, color, type, and placement of each screw. Be sure to return each screw to
its original location during reassembly.
Incorrectly routed or loose wire harnesses can interfere with other internal components and can become
damaged or broken. Frayed or pinched harness wires can be difficult to find. When replacing wire
harnesses, always use the provided wire loops, lance points, or wire-harness guides.
Removal and replacement strategy
WARNING! Turn the product off, wait 5 seconds, and then remove the power cord before attempting
to service the product. If this warning is not followed, severe injury can result, in addition to damage to
the product. The power must be on for certain functional checks during problem solving. However, the
power supply should be disconnected during parts removal.
Never operate or service the product with the protective cover removed from the laser/scanner
assembly. The reflected beam, although invisible, can damage your eyes.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do
not straighten pre-folds in the FFCs. You must Make sure that all FFCs are fully seated in their
connectors. Failure to fully seat an FFC into a connector can cause a short circuit in a PCA.
NOTE: To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread
pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw-hole
becomes stripped, repair the screw-hole or replace the affected assembly.
Electrostatic discharge
CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD reminder
when removing product parts. Always perform service work at an ESD-protected workstation or mat. If
an ESD workstation or mat is not available, ground yourself by touching the sheet-metal chassis
before touching an ESD-sensitive part.
Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the product.

Solve general problems
If the product is not responding correctly, complete the steps in the following checklist, in order. If the
product does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolves
the problem, you can stop without performing the other steps on the checklist.
Troubleshooting checklist
1. Make sure the product Ready light is on. If no lights are on, complete these steps:
a. Check the power-cable connections.
b. Check that the power switch is on.
c. Make sure that the line voltage is correct for the product power configuration. (See the label
that is on the back of the product for voltage requirements.) If you are using a power strip and
its voltage is not within specifications, plug the product directly into the wall. If it is already
plugged into the wall, try a different outlet.
d. Verify that connectors J2 and J7 on the formatter PCA are seated. See Figure 7-3
Components on the left side of the product on page 196.
e. Perform an engine test. If the test is successful, replace the control panel and then the
formatter PCA. See Top-cover assembly on page 124, Formatter PCA; HP LaserJet P2030
Series on page 130, or Formatter PCA; HP LaserJet P2050 Series on page 132.
2. Check the cables.
a. Check the cable connection between the product and the computer or network port. Make
sure that the connection is secure.
b. Make sure that the cable itself is not faulty by using a different cable, if possible.
c. Check the network connection. See Solve network problems on page 249.
3. Check to see if any messages appear on the control-panel display. If any error messages appear,
see Interpret control-panel messages (HP LaserJet P2050 Series Printers only) on page 219.
4. Check to see if any control-panel lights are lit. See Status-light patterns (HP LaserJet P2030 Series
Printers only) on page 209.
5. Make sure that the print media that you are using meets specifications.
6. Print a configuration page. See Print the information pages on page 48.
a. If the pages do not print, check that at least one tray contains print media.
b. If the page jams in the product, see Clear jams on page 230.
7. If the configuration page prints, check the following items.
If the page prints correctly, then the product hardware is working. The problem is with the
computer that you are using, with the printer driver, or with the program.
8. Select one of the following options:
Windows: Click Start, click Settings, and then click Printers, or Printers and Faxes. Double-
click the name of the product.
186 Chapter 7 Solve problems ENWW
-or-
Mac OS X: Open Print Center or Printer Setup Utility, and double-click the line for the product.
9. Verify that you have installed the printer driver for this product. Check the program to make sure
that you are using the printer driver for this product.
10. Print a short document from a different program that has worked in the past. If this solution works,
then the problem is with the program that you are using. If this solution does not work (the document
does not print), complete these steps:
a. Try printing the job from another computer that has the product software installed.
b. If you connected the product to the network, connect the product directly to a computer with
a USB cable. Redirect the product to the correct port, or reinstall the software, selecting the
new connection type that you are using.
Factors that affect product performance
Several factors affect the time it takes to print a job:
●Maximum product speed, measured in pages per minute (ppm)
●The use of special paper (such as transparencies, heavy paper, and custom-size paper)
●Product processing and download time
●The complexity and size of graphics
●The speed of the computer you are using
●The USB connection
●The product I/O configuration
●The amount of memory installed in the product
●The network operating system and configuration (if applicable)
NOTE: Although additional memory can improve how the product handles complex graphics and
improve download times, it will not increase maximum product speed (ppm).

192 Chapter 7 Solve problems ENWW
Tools for troubleshooting
The section describes the tools that can help you solve problems with your device.
Continuous self-test (HP LaserJet P2050 Series only)
The continuous self-test puts the device into a continuous printing mode without having to send jobs to
it.
1. Confirm that the product is in a Ready state. Press OK to enter the main menu.
2. Simultaneously press and hold the down arrow and Cancel button .
3. Press OK to re-enter the main menu.
4. Navigate to the secondary service menu.
5. Select Service Reports and then Cont. Self-Test.
To terminate the continuous self-test, press the Cancel button .
Half self-test functional check
The half self-test check determines which printing process is malfunctioning.
1. Print a Configuration page.
2. Press the print-cartridge-door button after the paper advances halfway through the product (about
five seconds after the motor begins rotating). The leading edge of the paper should have advanced
past the print cartridge.
3. Remove the print cartridge.
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 two functions of the electrophotographic process
are functioning (image formation and development). Troubleshoot the failure as a transfer or fusing
problem.
If there is no image on the photosensitive drum, perform these checks:
1. Make sure 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 to make sure that the drum is rotating.
3. Perform a high-voltage contacts check.
Drum rotation functional check
The photosensitive drum, located in the print cartridge, must rotate 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.
ENWW Tools for troubleshooting 193
3. Mark the drive gear on the cartridge with a felt-tipped marker. Note the position of the mark.
4. Replace 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. See Print cartridge on page 102.
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.
2. Verify that the thermistor connector is seated into both the product chassis and the ECU.
3. Remove the heating element connector from the ECU. 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. See Fuser on page 158.
4. Remove the thermistor connector, and then measure the resistance between J206 pins one and
two and between J206 pins three and four.
NOTE: Normal resistance between both pairs of pins is 370K ohms +/- 50K ohms at 20° C (68° F).
5. If no resistance is measured, replace the fuser. See Fuser on page 158,
High-voltage contacts check
The high-voltage contacts in the product must have a good connection with the contacts on the print
cartridge to provide the necessary voltages for the electrophotographic processes.
Checking the print cartridge contacts
When the product is turned on, high voltage is placed on the developer roller of the print cartridge. If the
antenna does not detect this voltage, the product displays an Install Black Cartridge message. Remove
the print cartridge and visually inspect the three connection points on the ends of the print cartridge:
primary charging contact (callout 1), developer roller contact (callout 2), and antenna contact (callout 3).
194 Chapter 7 Solve problems ENWW
If one is dirty or corroded, clean the connection with isopropyl alcohol. If one is damaged, replace the
print cartridge. See Print cartridge on page 102.

Repetitive image defect ruler
Defects on product rollers can cause image defects to appear at regular intervals on the page,
corresponding to the circumference of the roller that is causing the defect. Measure the distance between
defects that recur on a page. Use the following table or the repetitive-defect ruler to determine which
roller is causing the defect. To resolve the problem, try cleaning the roller first. If the roller remains dirty
after cleaning or if it is damaged, replace the part that is indicated in Table 7-9 Repetitive defects
on page 202.
CAUTION: Do not use solvents or oils to clean rollers. Instead, rub the roller with lint-free paper. If dirt
is difficult to remove, rub the roller with lint-free paper that has been dampened with water.
NOTE: The following table replaces the graphical repetitive defect ruler. You can make your own ruler
by using these measurements. For the most accurate results, use a metric ruler.

Paper-handling problems
Jams
Common causes of jams
Many jams are caused by using paper that does not meet HP specifications. For complete paper
specifications for all HP LaserJet products, see the HP LaserJet Printer Family Print Media Guide. This
guide is available at www.hp.com/support/ljpaperguide.
The product is jammed.
1
Cause Solution
The paper does not meet specifications. Use only paper that meets HP specifications. See Supported
paper and print media on page 32.
A component is installed incorrectly. Verify that the print cartridge is correctly installed.
You are using paper that has already passed through a product
or copier.
Do not use paper that has been previously printed on or copied.
A tray is loaded incorrectly. Remove any excess paper from the tray. Make sure that the
stack is below the maximum stack height mark in the tray. See
Load trays on page 38.
The paper is skewed. The tray guides are not adjusted correctly. Adjust them so they
hold the stack firmly in place without bending it.
The paper is binding or sticking together. Remove the paper, flex it, rotate it 180°, or flip it over. Reload
the paper into the tray.
NOTE: Do not fan paper. Fanning can create static
electricity, which can cause paper to stick together.
The paper is removed before it settles into the output bin. Reset the product. Wait until the page completely settles in the
output bin before removing it.
During two-sided printing, you removed the paper before the
second side of the document was printed.
Reset the product and print the document again. Wait until the
page completely settles in the output bin before removing it.
The paper is in poor condition. Replace the paper.
The internal rollers from the tray are not picking up the paper. Remove the top sheet of paper. If the paper is too heavy, it
might not be picked from the tray.
The paper has rough or jagged edges. Replace the paper.
The paper is perforated or embossed. Perforated or embossed paper does not separate easily. Feed
single sheets from Tray 1.
Product supply items have reached the end of their useful life. Check the product control panel for messages prompting you
to replace supplies, or print a supplies status page to verify the
remaining life of the supplies. See Print the information pages
on page 48.
Paper was not stored correctly. Replace the paper in the trays. Paper should be stored in the
original packaging in a controlled environment.

driver, make sure the appropriate media type is selected.
●Clean the inside of the printer.
●Check the media type and quality.
●In your printer driver, make sure the appropriate media
type is selected.
●Plug the printer directly into an AC outlet instead of into a
power strip.
Vertical repetitive defects
●The print cartridge might be damaged. If a repetitive mark
occurs at the same spot on the page, install a new
HP print cartridge.
●The internal parts might have toner on them. If the defects
occur on the back of the page, the problem will probably
correct itself after a few more printed pages.
●In your printer driver, make sure the appropriate media
type is selected.
Misformed characters
●If characters are improperly formed, producing hollow
images, the media stock might be too slick. Try a different
media.
●If characters are improperly formed, producing a wavy
effect, the printer might need service. Print a configuration
page. If the characters are improperly formed, contact an
HP-authorized dealer or service representative.
244 Chapter 7 Solve problems ENWW
Page skew
●Make sure that the media is loaded correctly and the
media guides are not too tight or too loose against the
media stack.
●The input bin might be too full.
●Check the media type and quality.
Curl or wave
●Check the media type and quality. Both high temperature
and high humidity cause media to curl.
●The media might have been in the input tray too long.
Turn over the stack of media in the tray. Also, try rotating
the media 180° in the input tray.
●Open the straight-through output door and try printing
straight through.
●The fuser temperature might be too high. In your printer
driver, make sure the appropriate media type is selected.
If the problem persists, select a media type that uses a
lower fuser temperature, such as transparencies or light
media.
Wrinkles or creases
●Make sure that media is loaded properly.
●Check the media type and quality.
●Open the straight-through output door and try printing
straight through.
●Turn over the stack of media in the tray. Also, try rotating
the media 180° in the input tray.
●For envelopes, this can be caused by air pockets inside
the envelope. Remove the envelope, flatten the
envelope, and try printing again.
ENWW Solve image-quality problems 245
Toner scatter outline
●If large amounts of toner have scattered around the
characters, the media might be resisting the toner. (A
small amount of toner scatter is normal for laser printing.)
Try a different media type.
●Turn over the stack of media in the tray.
●Use media that is designed for laser printers.
246 Chapter 7 Solve problems ENWW
Solve print-quality problems
You can prevent most print-quality problems by following these guidelines.
●Configure the trays for the correct paper-type setting. See Configure trays (HP LaserJet P2050
Series Printers only) on page 43.
●Use paper that meets HP specifications. See Supported paper and print media on page 32.
●Clean the product as necessary. See Clean the paper path (HP LaserJet P2050 Series Printers
only) on page 70.
Print-quality problems associated with paper
Some print-quality problems arise from using paper that does not meet HP specifications.
●The surface of the paper is too smooth.
●The moisture content of the paper is uneven, too high, or too low. Use paper from a different source
or from an unopened ream.
●Some areas of the paper reject toner. Use paper from a different source or from an unopened ream.
●The letterhead you are using is printed on rough paper. Use a smoother, xerographic paper. If this
solves your problem, ask the supplier of your letterhead to use paper that meets HP specifications.
●The paper is excessively rough. Use a smoother, xerographic paper.
●The paper is too heavy for the paper-type setting that you selected, so the toner is not fusing to
the paper.
For complete paper specifications for all HP LaserJet products, see the HP LaserJet Printer Family Print
Media Guide. This guide is available at www.hp.com/support/ljpaperguide.
Print-quality problems associated with the environment
If the product is operating in excessively humid or dry conditions, verify that the printing environment is
within specifications. See Operating environment on page 293.
Print-quality problems associated with jams
Make sure that all sheets are cleared from the paper path.
●If the product recently jammed, print two to three pages to clean the paper path.
●If the sheets do not pass through the fuser and cause image defects on subsequent documents,
print two to three pages to clean the paper path. If the problem persists, print and process a cleaning
page. See Clean the paper path (HP LaserJet P2050 Series Printers only) on page 70.
ENWW Solve print-quality problems 247
Solve performance problems
Problem Cause Solution
Pages print but are totally blank. The sealing tape might still be in the print
cartridges.
Verify that the sealing tape has been
completely removed from the print
cartridges.
The document might contain blank
pages.
Check the document that you are printing
to see if content appears on all of the
pages.
The product might be malfunctioning. To check the product, print a
Configuration page.
Pages print very slowly. Heavier paper types can slow the print
job.
Print on a different type of paper.
Complex pages can print slowly. Proper fusing may require a slower print
speed to ensure the best print quality.
Pages did not print. The product might not be pulling paper
correctly.
Make sure paper is loaded in the tray
correctly.
The paper is jamming in the product. Clear the jam. See Jams on page 229.
The USB cable might be defective or
incorrectly connected.
●Disconnect the USB cable at both
ends and reconnect it.
●Try printing a job that has printed in
the past.
●Try using a different USB cable.
Other devices are running on your
computer.
The product might not share a USB port.
If you have an external hard drive or
network switchbox that is connected to
the same port as the product, the other
device might be interfering. To connect
and use the product, you must
disconnect the other device or you must
use two USB ports on the computer.
248 Chapter 7 Solve problems ENWW
Solve connectivity problems
Solve direct-connect problems
If you have connected the product directly to a computer, check the cable.

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.

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 (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.

Agreement (“EULA”) is a contract between (a) you (either an individual or the entity you represent) and
(b) Hewlett-Packard Company (“HP”) that governs your use of the software product (“Software”). This
EULA does not apply if there is a separate license agreement between you and HP or its suppliers for
the Software, including a license agreement in online documentation. The term “Software” may include
(i) associated media, (ii) a user guide and other printed materials, and (iii) “online” or electronic
documentation (collectively “User Documentation”).

2. LICENSE RIGHTS. You will have the following rights provided you comply with all terms and
conditions of this EULA:
a. Use. HP grants you a license to Use one copy of the HP Software. “Use” means installing, copying,
storing, loading, executing, displaying, or otherwise using the HP Software. You may not modify the
HP Software or disable any licensing or control feature of the HP Software. If this Software is provided
by HP for Use with an imaging or printing product (for example, if the Software is a printer driver,
firmware, or add-on), the HP Software may only be used with such product (“HP Product”). Additional
restrictions on Use may appear in the User Documentation. You may not separate component parts of
the HP Software for Use. You do not have the right to distribute the HP Software.
b. Copying. Your right to copy means you may make archival or back-up copies of the HP Software,
provided each copy contains all the original HP Software’s proprietary notices and is used only for back-
up purposes.
3. UPGRADES. To Use HP Software provided by HP as an upgrade, update, or supplement (collectively
“Upgrade”), you must first be licensed for the original HP Software identified by HP as eligible for the
Upgrade. To the extent the Upgrade supersedes the original HP Software, you may no longer use such
HP Software. This EULA applies to each Upgrade unless HP provides other terms with the Upgrade. In
case of a conflict between this EULA and such other terms, the other terms will prevail.
4. TRANSFER.
a. Third Party Transfer. The initial end user of the HP Software may make a one-time transfer of the
HP Software to another end user. Any transfer will include all component parts, media, User
Documentation, this EULA, and if applicable, the Certificate of Authenticity. The transfer may not be an
indirect transfer, such as a consignment. Prior to the transfer, the end user receiving the transferred
284 Appendix A Service and support ENWW
Software will agree to this EULA. Upon transfer of the HP Software, your license is automatically
terminated.
b. Restrictions. You may not rent, lease or lend the HP Software or Use the HP Software for commercial
timesharing or bureau use. You may not sublicense, assign or otherwise transfer the HP Software except
as expressly provided in this EULA.

patent, and trademark laws. You will not remove any product identification, copyright notice, or
proprietary restriction from the Software.

disassemble the HP Software, except and only to the extent that the right to do so is allowed under
applicable law.
7. CONSENT TO USE OF DATA. HP and its affiliates may collect and use technical information you
provide in relation to (i) your Use of the Software or the HP Product, or (ii) the provision of support
services related to the Software or the HP Product. All such information will be subject to HP’s privacy
policy. HP will not use such information in a form that personally identifies you except to the extent
necessary to enhance your Use or provide support services.
8. LIMITATION OF LIABILITY. Notwithstanding any damages that you might incur, the entire liability of
HP and its suppliers under this EULA and your exclusive remedy under this EULA will be limited to the
greater of the amount actually paid by you for the Product or U.S. $5.00. TO THE MAXIMUM EXTENT
PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL HP OR ITS SUPPLIERS BE LIABLE FOR
ANY SPECIAL, INCIDENTAL, INDIRECT, OR CONSEQUENTIAL DAMAGES (INCLUDING
DAMAGES FOR LOST PROFITS, LOST DATA, BUSINESS INTERRUPTION, PERSONAL INJURY,
OR LOSS OF PRIVACY) RELATED IN ANY WAY TO THE USE OF OR INABILITY TO USE THE
SOFTWARE, EVEN IF HP OR ANY SUPPLIER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES AND EVEN IF THE ABOVE REMEDY FAILS OF ITS ESSENTIAL PURPOSE. Some states
or other jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so
the above limitation or exclusion may not apply 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.

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 might 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 on-
site 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.
Repack the product
If HP Customer Care determines that your product needs to be returned to HP for repair, follow these
steps to repack the product before shipping it.
CAUTION: Shipping damage as a result of inadequate packing is the customer’s responsibility.
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 (HP LaserJet P2050 Series Printers
only) on page 64.
2. Remove and retain the print cartridge.
CAUTION: It is extremely important to remove the print cartridge before shipping the product. A
print cartridge that remains in the product during shipping can leak and cover the product 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.
3. Remove and retain the power cable, interface cable, and optional accessories.
4. If possible, include print samples and 50 to 100 sheets of paper or other print media that did not
print correctly.
5. In the U.S., call HP Customer Care to request new packing material. In other areas, use the original
packing material, if possible. Hewlett-Packard recommends insuring the equipment for shipment.
288 Appendix A Service and support ENWW

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.
