Guide to Troubleshooting the Printer
Introduction
This chapter will guide you through the relevant steps to take when
troubleshooting the printer.
Troubleshooting System Error Codes
Chapter 2, System Error Codes contains a list of system error codes and
their respective descriptions and recommended corrective actions. Only try
one recommended action at a time and check if the error code has
disappeared.
If you have an error code which is not documented in this Service Manual or
you have an error which you cannot resolve, then report the error to the HP
Response Center or the nearest HP Support Office. When reporting the
error, have the following information ready:
„ Model and Serial Number of the printer.
„ Which firmware revision the printer is using (See Note below). Check
„
„
„
„
firmware in Utilities / Statistics / Code rev.
The complete error number (See Note below).
The Service Configuration Print.
The Current configuration sheet.
Which software application the customer is using (name, version, etc.).
When reporting the System Error Code, make sure that you
supply the full Error Code and the firmware version.
Without this information, HP Support Personnel cannot help
you.
Performing a Service Test on a failed Assembly
If possible, always perform a Service Test on the component/assembly that
you are about to replace, just to make sure that is the component/assembly
that has failed.
If the test on that component/assembly passes, you should
NOT replace it.
For information on the Service Tests and how to use them see Chapter 4,
Service Tests and Utilities.

Guide to Troubleshooting the Printer - Performing the Necessary Service Calibrations
Performing the Necessary Service Calibrations
Is the printer calibrated correctly after replacing a component? For
information on the Service Calibrations and how to use them see Chapter 5,
Service Calibrations.
Remember that certain Calibrations are required even if an
Assembly has been disassembled to gain access to another
Assembly or Component.
Solving Print Quality Problems
Whenever a Print Quality problem appears, it is advisable to print the
Diagnostic Print to help diagnose the problem. The Diagnostic Print will help
you differentiate between possible printhead errors and other problems such
as incorrect front-panel selection, driver or RIP configuration or mechanical
problems. For information on solving Print Quality problems see Chapter 6,
Print Quality.
The Printer does not Power ON
1 Check that the power cord is connected correctly to the Printer and to the
Power Socket.
2 Check that the Power Switch on the BACK of the Printer is in the ON
position.
3 Check to see the LED on the Front Panel Power Switch are On.
4 Check that the Front-Panel Cable is correctly connected to the Electronics
Module. Also make sure that the Front-Panel cable is not damaged.
5 Replace the Power Supply Unit ⇒ Page 8-153.
The Printer Continuously Rejects Printheads
1 Clean the flex contacts on the Printhead and in the Carriage Assembly using
the Carriage Interconnect Wiper (Refer to Page 3-22) and try again.
2 If ALL the Printheads are rejected (the status message on the Front Panel does
NOT show "OK" for ALL the Printheads) then perform the Electronic Module
Test ⇒ Page 4-20.
Cover Sensors are not Working
1 Perform the Sensors Test ⇒ Page 4-31.
2 Check if the cable for the faulty sensor is not damaged and is connected
correctly.
3 Replace the faulty Sensor.
The Line Sensor has Problems Detecting Media
1 Check the type of media that is being used since the Line sensor may have
problems detecting transparent media or some types of Non-HP media. Try
HP Designjet Printer Series — Service Manual
1-3
Chapter 1 Troubleshooting
loading white HP media in to the Printer and check if the Line sensor detects
it.
2 The Line Sensor is not calibrated correctly. Perform the Line Sensor
Calibration ⇒ Page 5-13.
3 The Line Sensor is damaged or faulty. Replace the Line Sensor ⇒ Page 8118.
Problems with Color Accuracy
1 The Color Sensor (ESP) is a powerful tool unique to the Z series printers to
maintain color accuracy. If you notice any problems with colors, perform the
Color Sensor (ESP) calibration. Refer to Page 5-16.
Troubleshooting Media Jams/Printhead Crashes
The failure modes "media jam" and "head crash" are grouped together
because in many cases a media jam causes the media to lift up into the
Carriage path and cause a Printhead crash, thus causing many media jam
failures to be reported as head crashes.
1 Did the media jam occur when loading media?
„ If the client has had media jams, it is common for pieces of media to get
stuck in the media path. Clear the media path.
When clearing a media jam, sometimes media is stuck in
the paper path. To clear this, you must lift the Media Lever
and insert thicker media into the paper path to push out the
media that is still stuck there.
2 Is the customer using non-HP media?
„ The use of non-HP media can easily be the cause of media jams and
head crashes (especially head crashes because HP media is specially
formulated to avoid cockle, one of the primary causes of head crashes). If
the media is not HP approved, advise the customer to use HP media and
check to see if the problem is now solved.
Banding at variable extreme environmental
conditions
Since the Accuracy Calibration has been done at normal environmental
conditions, printing in extreme environmental conditions will cause banding
because the advance of the Media Advance Roller does not correspond to
the same conditions that the calibration was done in. To solve the problem,
try the following:
Perform the Accuracy Calibration in the new environmental conditions (Refer
to the User’s Guide).
Worm marks on HP Coated media with light area
1-4
HP Designjet Printer Series — Service Manual
Guide to Troubleshooting the Printer - Solving Media-Handling Problems
fills
Light bands (S-shaped) in Paper axis direction where light area fills are
printed, causing unacceptable Image Quality defect.
„ Print the Service Configuration Print and check if the level of Humidity is
very low (below 30%). Increasing humidity may help in reducing the
severity of the problem.
The media is causing the problem and NOT the Printer. Do
not attempt to try and replace Printer parts to solve this
problem.
Solving Media-Handling Problems
The Front Panel indicates that media is misaligned or incorrectly positioned
Roll media
„ The roll may be loaded the wrong way. The paper should load over the
roll toward you.
„ Check that the paper is correctly loaded onto the spindle.
„ The paper may be loaded at an angle. The right-hand edge must be
aligned with the blue line on the Print Platen.
Ensure that the paper is wrapped tightly on the roll. This is
a very important step to remember because if this is not
done, the media may be loaded at an angle, causing the
media to be rejected.
Sheet media
„ Always load sheet media using the Rear Input Tray. Do NOT load the
„
„
„
„
media as you would load roll media.
It must be loaded with the right-hand edge against the blue line on the
Print Platen.
The media may be crumpled or warped or may have irregular edges.
If hand-cut media is used, the edges may not form a right-angle or they
may be rough. If possible, hand-cut media should not be used. Only
purchased sheet media should be used in the Printer.
If you have problems with paper jams, check that the Overdrive is not
obstructed by bits of paper or using the Turn Drive Roller Service Utility ⇒
Page 4-56.

Chapter 1 System Error Codes
Introduction
System error codes are hexa-decimal based numbers generally caused by
internal system errors. The following pages contain a list of system error
codes and their respective descriptions and recommended corrective
actions. Only try one recommended action at a time and check if the error
code has disappeared.
If you have an error code which is not documented in this Service Manual or
you have an error which you cannot resolve, then report the error to the HP
Response Center or the nearest HP Support Office. When reporting the
error, have the following information ready:
„ Model and Serial Number of the printer.
„ Which firmware revision the printer is using (See Note below). Check
„
„
„
„
firmware in Setup Menu / Information Menu / Show Printer Information.
The complete error number (See Note below).
The Service Configuration Print.
The Current configuration sheet.
Which software application the customer is using (name, version, etc.).
When reporting the System Error Code, make sure that you
supply the full Internal Error Code and the firmware
version. Without this information, HP Support Personnel
cannot help you. To view the Internal Error Code, hold the
UP key and press the CANCEL key at the same when the
System Error.
Code is displayed on the Front Panel.
This is the code definition required
when escalating a problem
Continuable and Non-Continuable Error Codes
Some of the Error Codes are continuable, which means you can press OK
on the front-panel and continue working with the Printer. Non-Continuable
Error Codes do not allow you to continue working with the Printer, in this
case power the Printer OFF and ON again and see if the System Error
disappears. If the Error Code reappears, then the Printer requires an on-site
visit in order to resolve the problem.
Even though the customer can continue working with a
Continuable Error Code, an on-site visit should still be
planned to troubleshoot the problem.

Introduction to Ink Supplies - What are Ink Supplies?
Introduction to Ink Supplies
What are Ink Supplies?
For each of the ink colors used in the printer, there are two components, the
Printhead and Ink Cartridge. These components are called Ink Supplies.
Printheads
Ink Cartridges
Ink Cartridges
The printer's eight Ink Cartridges provide matte black, photo black, light
gray, cyan, magenta, yellow, light magenta, and light cyan ink to the
Printheads. The color Ink Cartridges supplied with the printer have a
capacity of 69ml but optional 130 ml are also available.l
All these Ink cartridges are physically the same size. Only
the internal capacity varies.
The Ink Cartridges for the Z2100/Z3100 Photo Printer series require no
maintenance or cleaning. As long as each Ink Cartridge is inserted correctly
into its slot, the ink will flow to the Printheads. Because the Printheads control
the amount of ink transferred to the page, you will continue to see highquality printing results even when the ink levels are getting low.

Printheads
The Printheads are extremely durable and do not need to be replaced every
time an Ink Cartridge is replaced. They are independent of the Ink
Cartridges and will continue giving excellent image quality results even if the
Ink Cartridges are low on ink.
If you notice a decline in print quality such as lines or dots missing from text/
graphics, go to Page 6-21, Troubleshooting Print Quality Problems .

routine process, when all printheads are changed, takes 25 minutes. If the
printer finds problems in preparing the printheads, it will take longer, up to
55 minutes. For a single printhead insertion, the times vary between 15 and
35 minutes. After all printheads are checked and prepared, for the
printhead realignment.
Aligning Printheads
Precise alignment between printheads is essential for accurate colors,
smooth color transitions, and sharp edges in graphical elements. Your
printer has an automatic printhead alignment process which runs whenever
a printhead has been accessed or replaced.
In cases where the paper has jammed, you have used a custom paper, or
are experiencing problems with color accuracy you may need to align the
printheads. If the paper has jammed, it is recommended that you reinsert the
printheads and initiate the realignment procedure with the Image Quality
Maintenance menu.
Do not use transparent and semi-transparent paper to align
the printheads. Photo paper is recommended for the best
quality.
Reinsert Printheads Procedure
1 If the realignment process is running and the wrong paper is loaded, press
the cancel key on the front panel. Do not print if the realignment process has
been canceled. You can restart the alignment with the Image Quality
Maintenance menu procedure.
2 Load the paper you wish to use,. You can use a roll or cut sheet, however, it
must be A3 landscape or larger.
3 Remove and re-insert all the printheads, see Remove a printhead and Insert
a printhead. This will start the printhead alignment procedure.
4 Ensure the transparent window closed, as a strong light source near the
printer during printhead realignment can affect alignment.
5 The process will take about six minutes. Wait until the front panel display
shows the process complete before using the printer.
Image Quality Maintenance Procedure
1 Load the paper you wish to use. You can use a roll or cut sheet, however, it
must be A3 landscape or larger (420 by 297 mm). Do not use transparent
and semi-transparent paper to align the printheads. Photo paper is
recommended for the best results; plain, bond and thin coated papers
provide acceptable but marginal results.
2 Press the Menu key to return to the main menu and select the Image Quality
Maintenance menu icon.
3 Select Align printheads. The printer will check to see if it has enough paper
to run the realignment.
4 If the loaded paper is satisfactory, the printer will run the realignment and
print a realignment pattern. Ensure the transparent window is closed, as a

5 The process will take about five minutes. Wait until the front panel display
shows the process complete before using the printer.
Scanning errors during alignment
If the alignment process FAILs, a Scanning problems message appears on
the front panel. This means that the alignment has not completed
successfully. Therefore the printer is not aligned and the alignment should be
repeated before printing with good image quality. The problem may be due
to:
„ The paper used was not valid, repeat the alignment with valid paper.
„ Printhead health problems, clean printheads.
„ The alignment was done with the transparent window open, repeat the

Chapter 3 Ink Supplies Troubleshooting
Maintaining and Cleaning the Printheads
Clean the printheads
As long as the printer is kept turned on, an automatic cleaning is performed
periodically. This ensures there is fresh ink in the nozzles and prevents
nozzle clogs, which ensures color accuracy.
If you have not already done so, please refer to Horizontal lines across the
image (banding) and The Image Diagnostics Print before proceeding.
To clean the printheads, press the Menu key to return to the main menu and
select the Image Quality Maintenance menu icon, then Clean printheads. If
you have gone through the Image Quality Diagnostic print process, you
know which colors are failing. Select to the pair of printheads which contain
the failing colors. If you are not sure which colors to clean, you can also
select to clean all printheads.
Cleaning all printheads takes about nine minutes. Cleaning a single pair of
printheads takes about six minutes. Cleaning all printheads uses more ink
than cleaning a single pair.
If you have cleaned the printheads using the Clean printheads procedure
from the front panel and are still experiencing image quality problems, you
can try cleaning the printhead nozzles manually using the following
procedure.
This is a delicate process and may damage the printhead.
Do not touch the electrical connections on the backside of
the printhead.
You must remove the printhead (see Remove a printhead) and using a cotton
swab and a little de-ionized, distilled water, or Carriage Interconnect Wiper
clean the bottom of the printhead until the residue is removed.
Flex Contacts Cleaning Tool
The Flex Contacts Cleaning Tool is part of the Maintenance
Tool Kit which can be ordered using Part Number Q566960690. All the instructions needed to use the Flex Contacts
Cleaning Tool will be packaged with the kit.
Whenever you replace the Printhead, check the empty slots to see if they
need cleaning. In extreme circumstances, when a Printhead is inserted, it is
possible that the Printer will not recognize it due to the build-up of ink on the
electrical connection between the Printhead and the Carriage Assembly.
3-22
HP Designjet Printer Series — Service Manual
Maintaining and Cleaning the Printheads - Flex Contacts Cleaning Tool
Included with the Z2100/Z3100 Photo Printer is a Flex Contacts Cleaning
Tool. This tool is provided in a separate package. It also contains
replacement sponges and an instruction sheet. This tool should be used for
cleaning the electrical interconnects of both the Carriage Assembly and the
Printhead.
If the front panel displays the message “Reseat” or “Replace” next to the
offending printhead, try cleaning the flex circuits of the Carriage and the
Printheads using the Carriage Interconnect Wiper.
Do not touch, wipe or attempt to clean the printhead
nozzles. This can damage the printhead and reduce print
quality.

Chapter 4 Service Tests and Utilities
Introduction
This chapter explains how to use the built-in Service Tests and Service
Utilities and what to do if any of the Service Tests FAIL.
If possible, always perform a Service Test on the component
that you are about to replace, just to make sure that is the
component that has FAILed. If the test on that component
passes, there is no need to replace it.
Diagnostics - Self Test
Initialization Sequences
Whenever the Printer is switched ON, it automatically performs a series of
internal self tests and mechanical initialization sequences. If any of the parts
FAIL, a system error will appear and you should consult 2, System Error
Codes.
Phone Support
In certain circumstances, a Call Agent can try and
troubleshoot the Printer by requesting the Customer to
perform a Service Test via the phone. Using this process, it
can be determined whether the Printer requires any on-site
maintenance.

The Service Tests work in a special Mode which does NOT
require the full Initialization of the Printer. Therefore it is
important that once you have finished with the Service
Tests, you MUST power OFF the Printer and Power ON
again before trying to print or before executing another
Service Test.
In some cases a quick press of a button may not be
recognized by the Printer. When pressing a button, be sure
to press it deliberately and all the way to the bottom of its
travel.
If the Printer hangs up during a test, switch the Printer OFF
and restart from step 1.

The Service Image Quality Diagnostic Print - Printing the Diagnostic Print
Considerations for Printing the Diagnostic Print
1 The IQ Diagnostic Print prints in A3 and B sizes so you must have media
loaded (roll or sheet) that is this size or larger.
2 Use the same type of media that the customer was using when they found
the image quality problem.
3 If the customer is using non-HP media and after the Image Quality Test you
still have the same image quality problems, change to genuine HP media
and repeat the Image Quality Test.
4 If you do not see any problems with the Image Quality Test, the problem
may not be with the printer itself. The problem may be with the RIP or the
driver.
If you do see problems with the Image Quality Test, continue with the
Advanced Diagnostic procedures which will help you diagnose the problem.
Printing the Diagnostic Print
1 In the Service Utilities submenu, scroll to “Diagnostic Print” and press OK.
2 You will be given three options. Use the Arrow keys to make the selection
and press the OK key to start printing the required Diagnostic Print or to
enter the Advanced Diagnostics menu.
3 If you selected the Advanced Diagnostics Prints in the previous step, use the
Arrow keys to make the required selection Paper Advance, Visual

Reading the Diagnostic Print Results
Diagnostic Part 1: Printhead Reliability
The Nozzle Print Test test is designed to check if the Printhead nozzles print
correctly.
The nozzles check (bottom of the plot) is printed in a one-pass full swath
mode. The diagnostics test prints out every single nozzle of each Printhead
without applying an error hiding or alignment algorithm.
For each Printhead, you can see both the adjacent and the consecutive
nozzles.
If any nozzles are not printing correctly they will be shown on the right of
each Printhead Nozzle test.There is a series of numbered stepped diagonal
lines. If one or more of the nozzles are clogged, malfunctioning or mispositioned, you will see that the stepped lines are broken or misdirected in
one or more places.
Below, the stepped lines highlighted in yellow are broken. When the line is
completely broken, this means the nozzle is out.
HP Designjet Z3100/Z2100/Z3100ps GP Photo Printer Series — Service Manual

Chapter 6 Print Quality
Below, the stepped lines highlighted in yellow are misdirected. When the
line is misdirected, this means the nozzle is malfunctioning or out of
position.
On the left of each Printhead Nozzle test, there is a series of horizontal
straight lines. If one or more nozzles are misdirected there will be unequal
spaces between the corresponding lines.
Corrective Action
If the printer has nozzle defects, you can still get perfect print quality results.
The printer can automatically compensate for nozzle defects, so there is no
need to replace the Printhead.
The method of improving Nozzle Defects is to:
1 Recover the Printheads, using the Front Panel Main Menu/Image Quality
Maintenance/Clean Printheads option.
2 Reprint the Printhead Nozzles Test Plot to verify that the defective nozzles
have been corrected.
3 If the problem continues, replace the defective Printhead.
Diagnostic Part 2: Printhead Alignment
This test is designed to check any color-to-color and bi-directional
misalignment the printer may have.
1 If the Printer is experiencing horizontal misalignment problems, the

Corrective Action
Perform the Printhead Alignment (Main Menu/Image Quality Maintenance/
Align Printheads), using the same paper type with which you were
experiencing unacceptable image quality, if feasible (some paper types are
not suitable for Printhead Alignment).
Diagnostic Part 3: Printheads & Paper Advance
This test is designed to check whether the Printheads and the Paper Advance
Mechanism are working correctly. This part of the Image Quality Test should
NOT be used to check for color consistency or accuracy.

Banding
If the Printer is experiencing a banding problem, you will see repetitive
horizontal bands within the printed image.
„ Darker horizontal bands or lines repeated along the vertical band (from
top to bottom at the same distance).
„ Whiter horizontal bands or lines along the vertical band (from top to
bottom at the same distance).
The plot is printed in Best or Normal mode (according to the menu option
selected) with Error Hiding ON. The top band has 100% ink density patches
while the bottom band has 50% ink density patches.
Troubleshooting Banding Problems
If banding does NOT occur in ALL the colors, then it is more than likely a
Printhead problem. In this case, try the following:
1 Check that the appropriate print quality settings are being used (refer to the
User’s Guide for more information).
2 Recover the printheads using the option through the Front Panel (Main
Menu/Image Quality Maintenance/Clean Printheads). Reprint the
Diagnostic Print or the print file and if the problem persists, replace the faulty
Printhead.
If banding does occur in ALL the colors, then it is more than likely a Paper
Advance problem:
„ If the bands are light, it means that the paper has advanced too much.

HP Designjet Z3100/Z2100/Z3100ps GP Photo Printer Series — Service Manual
Reading the Diagnostic Print Results - No Printing Defects Found in the Diagnostic Print
„ If the bands are dark, it means that the paper hasn’t advanced enough.
„ In high quality modes, graininess in ALL colors can indicate problems
either with alignment or Paper Advance.
Corrective Action
In order to solve problems that result in banding, try the following:
1 Check that the appropriate print quality settings are being used (refer to the
User’s Guide for more information).
2 Check that the loaded media is the same type as selected in the printer. You
can verify the media type selected through the Front Panel (Main Menu/
Paper menu/View loaded paper).
3 If the customer is using low quality paper, try recommending better quality
paper (preferably HP paper). Printer performance can only be guaranteed
by using recommended papers.
4 Perform the Paper Advance Calibration using the same type of paper that
will be used for the final print (Main Menu/Image Quality Maintenance/
Paper Advance Calibration/Calibrate Paper Advance).
If there is white point banding in only one color band and the problem
cannot be fixed using the Printhead recoveries, in some cases using the force
a drop detection option can fix this issue. See Force Drop Detection, Page
6-20.

Paper Advance
This plot helps you to visually check any alignment problems of the printer.
You use it to precisely measure the media advance error with a one dot row
accuracy, and to verify the stability of the media advance.
The whitest vertical line should be positioned in the 0 offset column with
minor variations between +2 and -2 columns. If the offset is not positioned
on the 0 column or between +2 and -2 columns and the whitest vertical
varies greatly, the printer requires Paper Advance Calibration (Main Menu/
Image Quality Maintenance/Paper Advance Calibration/Calibrate Paper
Advance).
It is very important to verify that the loaded media is the
same media type as selected in the front panel. You can
verify the media type selected through the Front Panel (Main
Menu/Paper menu/View loaded paper). The wrong type of
paper selected will produce an offset error in the Paper
Advance.

The following plot shows a bad media advance, there is a straight white line
positioned close to the -6 column, instead of the 0 column for the majority of
the points.
Corrective Action
To fix Paper Advance problems, try the following:
1 Check the Paper Advance Calibration Status. This can be done by going to
Main Menu/Paper/View Loaded Paper. At the bottom, the Front Panel
displays the Paper Advance Calibration status. There are three status
messages:
„ DEFAULT. The paper loaded is recognized as HP paper, which is
already optimized and calibrated for the printer. Do Not calibrate the
Paper Advance for this paper.
„ RECOMMENDED. The paper loaded is NOT recognized as HP paper,
and Paper Advance values have NOT been customized for this paper
type. In this case, calibrate the Paper Advance from the user menu.
„ OK. This indicates that the paper loaded has been calibrated before. If
the printer continues to have banding and graininess problems, calibrate
the Paper Advance from the user menu.
Whenever the printer's firmware is upgraded, the paper
advance calibration values will be reset to factory default.

Reading the Advanced diagnostic Print Results - Printhead Alignment
2 To calibrate the Paper Advance from the user menu, go to Main Menu/
Image Quality Maintenance/Paper Advance Calibration/Calibrate
Paper Advance.
It is very important to verify that the loaded media is the
same media type as selected in the front panel. You can
verify the media type selected through the Front Panel (Main
Menu/Paper menu/View loaded paper). The wrong type of
paper selected will produce an offset error in the Paper
Advance.
Some paper types are not suitable for Paper Advance
Calibration. Do NOT use colored papers or transparent
materials such as translucent bond, clear film, matte film,
tracing paper, or vellum.
Paper Advance calibration from the user menu will only calibrate the Paper
Advance for the paper type loaded in the printer at that moment.
3 If Calibrate Paper Advance has mostly solved the problem, try Adjust Paper
Advance to fine tune the Paper Advance (Main Menu/Image Quality
Maintenance/Paper Advance Calibration/Adjust Paper Advance).
Select the percentage of change from -100% to 100%. To correct light
banding, decrease the percentage. To correct dark banding, increase the
percentage.
4 The Paper Advance calibration from the service menu will calibrate the
Paper Advance for ALL paper types. This action is recommended when:
„ The Paper Advance calibration from the user menu does NOT solve the
problem.
„ The Paper Advance problems affect ALL paper types.
The procedure for Paper Advance Calibration from the service menu is
documented in Chapter 5, Service Calibrations. See Paper Advance
Calibration, Page 5-7.
Printhead Alignment
This plot helps you to visually check any alignment problems of the printer.
You use it to precisely measure the alignment error with a one dot row
accuracy. For the printer to be considered correctly aligned, the results must
be within ±1 dot row.

Test b should NOT be used by Service Engineers.
c Nozzle Print Test which is also part of the Image Quality Service Plot.
This test is designed to check that the Printhead nozzles print correctly.
The test prints out every single nozzle of each Printhead. No error hiding
or Printhead Alignment algorithm is applied. For each Printhead, you can
see both the adjacent and the consecutive nozzles.
This is what you would see in the Nozzle Print Test part if there are
nozzles not printing correctly:
1 On the right of each Printhead Nozzle test, there is a series of numbered
stepped diagonal lines. If one or more of the nozzles are malfunctioning or
mis-positioned, you will see that the stepped lines are broken or misdirected
in one or more places.
2 On the left of each Printhead Nozzle test, there is a series of horizontal
straight lines. If one or more nozzles are misdirected there will be unequal
spaces between the corresponding lines.
Corrective Action for Nozzle Defects
If the printer has nozzle defects, it does not mean that you will not get
perfect print quality results. The printer has automatic procedures to hide
many nozzle defects.
1 Recover the Printheads using the option through the Front Panel (Main
menu/Image quality maintenance/clean printheads).
2 Reprint the Nozzle Print test to check that the defective nozzles have been
corrected.
3 If the problem continues, replace the defective Printhead.
Force Drop Detection
If the Nozzle Print Test plot has persistent white point banding in only
one color that cannot be fixed with a printhead recovery, you can use this
option to resolve the problem by resetting the nozzle health data base so
that all nozzles are assumed to be correct.
Once the nozzle health data base has been reset drop detection is forced.
The normal cause of this white point banding in a single color is the
incorrect detection of failed nozzles by the drop detector.

Troubleshooting Print Quality Problems - Ink marks on the paper
Print Scuffing or Scratching when Touched
Description of problem
The black ink pigment can smudge when touched by a finger, a pen, or
some other object. This is particularly noticeable on coated paper, matte
proofing paper, and fine art material.
Glossy paper may be extremely sensitive to damage from the basket or to
anything else that it contacts soon after printing, depending on the amount
of ink used and the environmental conditions at the time of printing.
Corrective Action
1 Handle prints carefully.
2 Avoid stacking prints on top of each other.
3 Disable the automatic cutter before printing, so that the print will not fall into
the basket.
Ink marks on the paper
This problem may occur for several different reasons.
Horizontal smears on the front of coated paper
If a lot of ink is used on plain or coated paper, the paper absorbs the ink
quickly and expands. As the printheads move over the paper, the printheads
may come into contact with the paper and smear the printed image. This
problem is normally seen only on cut sheets of paper (not on roll paper).
Corrective Action
1 Check that the paper type loaded corresponds to the paper type selected in
the front panel and in the software. You can verify the paper type selected
through the Front Panel (Main Menu/Paper menu/View loaded paper).
2 Use a recommended paper type and the correct print settings.
3 If using sheet paper, try rotating the sheet 90 degrees. The orientation of the
paper fibers may affect performance.

5 Try to increase the margins by relocating the image to the center of the page
with the software application being used.
Ink marks on the back of the paper
This can happen after a lot of border less printing, especially with nonstandard paper sizes. Ink residues on the platen are likely to mark the back
of the paper.
Corrective Action
„ Clean the platen with a soft cloth. Clean each rib separately without
touching the foam between the ribs.

1 Try using a heavier paper type. When printing dense colors, it is
recommended to use HP Heavyweight Coated Paper HP Super,
Heavyweight Coated Paper or thicker Digital Fine Art papers.
2 Use higher print quality settings (refer to the User’s Guide for more
information).
White spots on the print
White spots are seen on the print. This is probably due to paper fibers, dust,
or loose coating material.
Corrective Action
1 Clean the paper manually with a brush before printing, to remove any loose
fibers or particles.
2 Always keep the cover of the printer closed.
3 Protect paper rolls and sheets by storing them in bags or boxes.

Chapter 6 Print Quality
Problems with Color Accuracy
Corrective Action
1 Ensure that the paper type being used has been color calibrated, which will
give color consistency from print to print, and from Printer to Printer.
2 Check that printing is on the correct side of the paper.
3 Check that the appropriate print quality settings are being used (refer to the
User’s Guide for more information). Reprint the job in case the problem has
been solved.
4 If the problem consists of color differences between your print and your
monitor, please follow the instructions in the "How to calibrate your monitor"
section of the HP Color Center. At this point, you may wish to reprint your
job in case the problem has been solved.
5 Select suitable options in the application (refer to the User’s Guide for more
information).
6 Print the Service Image Diagnostics Print, and clean any printheads that
need cleaning. Reprint the job in case the problem has been solved.
Color accuracy using EPS or PDF images in page layout
applications
Page layout applications such as Adobe InDesign and QuarkXPress do not
support color management of EPS, PDF, or grayscale files.
If these types of files have to be used, try to ensure that the EPS, PDF, or
grayscale images are already in the same color space that is intended to be
used later on in Adobe InDesign or QuarkXPress. For instance, if the final
objective is to print the job in a press that follows the SWOP standard, at the
time of creating the EPS, PDF or grayscale the image should be converted
into SWOP.
Output Only Contains a Partial Print
If the output that was expected only contains a partial image, then try the
following to resolve the problem:

Troubleshooting Print Quality Problems - Problems with Image Clipping
1 Was the Cancel key pressed before all the data was received by the Printer?
If so, send the file again and make sure that the Cancel key is not pressed.
2 The I/O Timeout setting may be too short. Increase the I/O timeout setting
(Setup Menu/I/O Setup/IO Timeout) and then send the file again.
3 There might be a communications problem between the Printer and
Computer. Check the USB or network cable between the computer and the
Printer to make sure it is not damaged and is connected correctly.
4 Make sure that the software settings are correct for the current page size
(e.g. long-axis prints).
5 If network software is being used, make sure it has not timed out.
Problems with Image Clipping
This normally indicates a discrepancy between the actual printable area on
the loaded paper and the printable area as understood by the software. This
kind of problem can often be identified before printing by previewing the
print.
„ Check the actual printable area for the paper size that is loaded.
printable area = paper size – margins
„ Check what the software understands to be the printable area (which it
„
„
„
„
„
„
may call “printing area” or “imageable area”). For example, some
software applications assume standard printable areas that are larger
than those used in this Printer.
If a custom page size with very narrow margins has been defined, the
printer may impose its own minimal margins, clipping the image slightly.
Consider using a larger paper size, or border less printing.
If the image contains its own margins, it may be possible to print it
successfully by using the Clip Contents by Margins option.
If a very long image needs to be printed on a roll, check that the software
is capable of printing an image of that size.
The page may have been rotated from portrait to landscape on a paper
size that is not wide enough.
If necessary, change the printable area in the software.
If necessary, reduce the size of the image or document in your software
application, so it fits between the margins
Another Possible Explanation
Some applications, such as Adobe Photoshop, Adobe Illustrator, and
CorelDRAW, use an internal 16–bit coordinate system which means that
they cannot handle an image of more than 32,768 pixels. If you try to print
an image larger than this from these applications, the bottom of the image
will be clipped. In this case, the only way to print the whole image is to
reduce the resolution so that the whole image requires fewer than 32,768
pixels. The HP-GL/2 printer driver contains an option called Compatibility
with 16–bit applications, which can be used to reduce the resolution of
such images automatically. This option can be found option in the Advanced
tab, under Document Options > Printer Features.

Chapter 6 Print Quality
Some objects are missing from the printed image
Large quantities of data may be necessary to print a high-quality largeformat print job, and in some specific workflow there may be issues that can
lead to some objects missing from the output.
Corrective Action
„ In the Advanced tab, select Document options, Printer features, and set
Send job as bitmap to Enabled (HP-GL/2 driver only).
„ In the Advanced tab, select Document options, Printer features, and set
16-bit App. Compatibility to Enabled.
„ In the Advanced tab, select Document options, Printer features, and set
Max. Application resolution to 300.
The above settings are mentioned for troubleshooting purposes and may
adversely affect the final output quality or the time necessary to generate the
print job. Therefore, they should be restored to their default values if they do
not help to solve the problem.
When working under Mac OS, the above settings are not available. Instead,
try reducing the resolution of bitmap images in the application software
being used.
A PDF file is clipped or objects are missing
In older versions of Adobe Acrobat or Adobe Reader, large PDF files could
be clipped or lose some objects when printing with the HP-GL/2 driver at
high resolution. Upgrade the Adobe Acrobat or Adobe Reader software to
the latest version. From version 7 onwards, these problems should be solved.

Removal and Installation
Introduction
This chapter is a step-by-step guide to the removal and installation of the key components of the
printer. You may find it useful to check off the steps as they are performed. Use the illustrations
for each procedure to identify the parts referred to in the text.
The procedures appear in order of removal. The whole machine can be stripped down by
starting at the beginning of this chapter and working through the subsequent procedures.
Before using this chapter to remove and install a new component, always
make sure that you have performed the relevant service test from Chapter 4.
If the test passes you will not need to replace the component.
Safety Precautions
Review the instructions identified by WARNING and CAUTION symbols before you service the
printer. Follow these warnings and cautions for your protection and to avoid damaging the
printer.
Serious shock hazard leading to death or injury may result if you do not take
the following precautions:
•Ensure that the ac power outlet (mains) has a protective earth (ground)
terminal.
•Switch the plotter off, and disconnect it from the power source prior to
performing any maintenance.
•Prevent water or other liquids from running onto electrical components or
circuits, or through openings in the module.
Electrostatic Discharge (ESD) Precautions
To prevent damage to the Printer circuits from high-voltage electrostatic discharge (ESD):
1.Do not wear clothing that is subject to static build-up.
2. Do not handle integrated circuits (ICs) in carpeted areas.
3. Do not remove an IC or a printed circuit assembly (PCA) from its conductive foam pad or
conductive packaging until you are ready to install it.
4. Ground (earth) your body while disassembling and working on the Printer.
5. After removing a cover from the Printer, attach an earthing (ground) lead between the PCA
common and earth ground. Touch all tools to earth ground to remove static charges before
using them on the Printer.
6. After removing any PCA from the Printer, place it on a conductive foam pad or into its
conductive packaging to prevent ESD damage to any ICs on the PCA.

Service Calibration Guide to Removal and Installation
Using the Service Calibration Guide
When you remove most Z2100/Z3100/Z3100ps printer components, you will need to perform a
particular set of Service Calibrations and Diagnostic tests to ensure proper printer performance.
The Service Calibration Matrix explains which service calibrations and diagnostic tests (top row)
need to be performed whenever you remove and install particular printer components (left most
column).
A number in the body of the table indicates that the service calibration of the same column must be
performed whenever you remove the corresponding component. The calibrations must be
performed in the order they are numbered.
Start by locating the component you have removed and installed in the left most column.
Even if you do not replace the removed component with a new component,
you still need to perform the calibrations indicated by the matrix.

Preventive Maintenance
Moisture on the Printer
Users should use the Printer in an environment between 20% and 80%
relative humidity. To recover from moisture condensation, turn the Printer Off,
and, using the main roller as a reference, wait until the Printer is completely
dry before using it again.
Noisy Carriage Bushing
To prevent noisy movement of the carriage, remove aluminum or dust
particles from the bushing at the back of the carriage, and from the slider
path along which the bushing moves. Lubricate the slider path using the
Lubrification Kit (Q5669-60692).
Belt Swelling
To prevent new belts from swelling incorrectly, keep them in their bags with
desiccant until you need to install them.
Cleaning the Printer
To maintain the Printer in good operating condition, keep it free of dust
accumulation, ink, and other contamination. Cleaning intervals are
determined by the Printer environment and by the types of Printer supplies
used.
Carriage Assembly Lubrication
To ensure correct operation of the printer you must lubricate the Carriage
Assembly whenever any of the following are encountered if:
„
„
„
„
The Front Panel displays "Maintenance #1 required".
There is excessive noise when moving the Carriage Assembly.
A shut down of the carriage PWM error message appears.
There are IQ (vertical banding problems).
You should also lubricate the Carriage Assembly whenever you change any
of the following service parts:
„ The Carriage Rear Bushing.
„ The Carriage Assembly.
„ The Carriage Rail Oiler.
To lubricate the Carriage Assembly you will require the Lubrification Kit
(Q5669-60692). Use the following procedure to lubricate the Carriage
Assembly:
1 Use the IPA alcohol (Q6675-60070) and the cleaning cloth to clean the
Carriage Rail and the Carriage Slider Rod.
9-2
HP Designjet Z3100Z2100Z3100ps GP Photo Printer Series — Service Manual
Preventive Maintenance - General Cleaning
2 Use an Oil Dispenser (Q6675-60062) to lubricate the Carriage Rail and the
Carriage Slider Rod.
3 Replace the Carriage Rail Oiler (refer to page 8-110) with the new one
contained in the kit and add 2-3 drops of oil to the foam of the Carriage Rail
Oiler.
4 Use an Oil Dispenser (Q6675-60062) to lubricate the Carriage Rear
Bushing.
General Cleaning
Proper general cleaning should include the following:
To prevent an electric shock, make sure that the Printer is
switched OFF and unplugged before any cleaning is
performed. Do NOT let any water get inside the Printer.
1 Blow away dust accumulation with compressed air if available.
2 Clean the outer surface of the Printer with a damp sponge or cloth. Use a
mild soap and water solution if necessary. Do not use abrasive cleaners.
3 Wipe the Printer dry with a soft lint-free cloth.
Cleaning the Drive Roller and Overdrive
If ink is spilled on the Overdrive, remove the ink
immediately. Due to the ink's reflectance, ink on the
Overdrive can disrupt the Printer's edge-sensing function.
To remove any ink from the Overdrive, perform the
following procedure:
Prevent water or other liquids from running onto electrical
components or circuits, or through openings in the
Electronics Module.
1 Perform the Turn Drive Roller Utility (Refer to Page 4-56).
2 Open the window and apply any common household cleaning solution
(water based only) to a soft, lint-free rag and apply it to the Drive Roller and
Overdrive surface while it is rotating. Make sure that you thoroughly clean
the Drive Roller and Overdrive surface.
3 Press Enter when you have completed the cleaning procedure.
4 Allow the Drive Roller to dry before loading media in to the Printer.
Level of Printer Usage
Normal printer use means 6,000,000 Carriage Cycles (which corresponds
to approximately 100,000 A0 prints on average). Under normal usage
conditions, it will be approximately 5 years before the printer needs
maintenance. If the printer is used more than the normal usage conditions,
then it will need maintenance service much more frequently.
