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 3,
Service Tests and Utilities.

Troubleshooting
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 Service
Calibration Guide to Removal and Installation, Page 6-8 and Chapter 4,
Service Calibrations.
Remember that certain Calibrations are required even if an
Assembly has been disassembled to gain access to another
Assembly or Component.
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 6-164.
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 1-72) 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 3-22.
Cover Sensors are not Working
1 Perform the Sensors Test ⇒ Page 3-33.
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
loading white HP media in to the Printer and check if the Line sensor detects
it.
2 Sometimes the line sensor has problems detecting media when sheet media
is loaded without a skew check. If the media type allows, always use the
automatic skew check feature. If the media type does not allow automatic
skew check, manually check that the media is correctly positioned.

General Troubleshooting
3 The Line Sensor is not calibrated correctly. Perform the Line Sensor
Calibration ⇒ Page 4-15.
4 The Line Sensor is damaged or faulty. Replace the Line Sensor ⇒ Page 6128.
Problems with Color Accuracy
1 The Color Sensor ESP (spectrophotometer) 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 (spectrophotometer) calibration. Refer
to Page 4-18.
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.
3 Has media been loaded without skew check?
 Loading media without skew check can cause printhead crashes both
during loading and while printing. Whenever automatic skew check is
available for a media type, it should be used. If automatic skew check is
not allowed for the media type, manually check that the media is
correctly positioned.
 Standard/Normal Cut Sheets, depending on the degree of skew, cause
printhead crashes when the corners are not evenly controlled (they are
not pinched at the same time). This makes it more likely that the paper
will be bent or damaged. Frequently, the paper curls upward when the
paper expands due to ink absorption.
 Commercial FA Arts Sheets have the same problem as the Standard/
Normal Cut Sheets described above. The difference is that the
Commercial FA Arts Sheets have a weak, irregular edge that often makes
the problem worse.
 Hand-cut Rollsheets or Leftovers are not supported by the printers because
errors are frequently made by the operator that cause printhead crashes.

General Troubleshooting
The printer has problems ejecting sheet media
The printer has problems ejecting sheet media, either continuing to eject the
paper long after it has been ejected or stopping the ejecting process before
the paper is completely ejected from the printer. To solve the problem, try the
following:
 Load media using the skew check feature whenever it is possible. When
sheet media is loaded without the skew check feature, the printer
estimates the length of the paper to be 4 times the width. If this estimate is
either too short or too long, the printer will not properly eject the media.
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 conditions present when the calibration was performed. 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
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.
 Make sure you choose the correct loading option on the Front Panel.

General Troubleshooting
Sheet media
 Always load sheet media using the Rear Input Tray. Do NOT load the
media as you would load roll media, unless you are getting marks on the
media with thick cut sheet media.
 It must be loaded with the right-hand edge against the blue line on the
Print Platen.
 Load the sheet media without skew check.
 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 3-61.
 Make sure you choose the correct loading option on the Front Panel.

Software Troubleshooting
Software Troubleshooting
General advice:
Check that you have the latest driver release. Driver releases are available at
www.hp.com/go/graphicarts
Installation
If the driver is available in a share drive, copy the installer or zip file locally
into the hard disk before executing it.
The drivers are published in different formats in the web
 Installer for Windows (.exe file that can be executed to start the
installation)
 Compressed package including all files that are needed to install the
driver through the Add a Printer Wizard in Windows (.exe file that can
be automatically extracted)
 Image file for Mac (.dmg file)
Usually the Windows installer includes other components apart from the
driver, like the HP Standard TCP/IP Port. This is the recommended port type
when you need to install the printer on the network, so make sure that you
have installed the driver with the installer at least once to have this port type
available.
If you want to upgrade the driver in the future, although it is recommended
to continue using the installer, you can use the manual wizard if you are
concerned about file download size. When you install the driver from the
original CD/DVD, you are using the Installer so the necessary components
will be installed also.
Installation logs are located at:
 C:\windows\hpdjxxxx.log (different for each printer name)
 C:\windows\sounder.his
 C:\windows\hpntwksetup.ini
They might be useful in case of escalating an installation error to the Lfp

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 the paper was loaded without the skew check feature, the preview
function may not function correctly because the printer must estimate the
paper length. Whenever possible, load media using the skew check
feature.
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. An image 32,768 pixels long would print at a length of 54.61 in or
1.39 m if you select Best or Quality in the driver, 109.23 in or 2.78 m if you
select Fast, Normal or Speed in the driver.
To print the whole image, try these suggestions:
 When printing into a PS printer, Try using the PostScript printer driver to
print your job, if you have not already tried it
 The Windows PCL3 driver dialog includes an option called Max.
application resolution, which enables you to print successfully in this
situation. For the Z3200 it is set to Auto. For older products, or if you
want to make sure that the resolution is lowered, you might need to
change the setting manually to 300. You can find the option in the
Advanced tab, under Document Options > Printer Features.
 Save the file in another format, such as TIFF or EPS, and open it with
another application.
 Use a RIP to print the file.

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:
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.

Software Troubleshooting
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.
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.
 Select a smaller page size and scale to the desired final page size in the
driver or in the front panel.
 Save the file in another format, such as TIFF or EPS, and open it with
another application.
 Use a RIP to print the file.
 Reduce the resolution of bitmap images in your application software.
 Select a lower print quality in order to reduce the resolution of the printed
image.
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.
If the spool file size is bigger than 1GB, part of the
image will be clipped
Versions affected: Any application in Windows XP
Drivers affected: Drivers that use EMF spooling
Description:
Some drivers generate spool files in EMF format. The OS has a limitation in
the size of this EMF file. Currently the drivers that use EMF are:
 Z2100/Z3100 PCL3GUI driver
 Z2100/Z3100 HP-GL/2 driver if the preview or back to front printing
settings are used
Corrective Action
 Reduce the resolution.


Designjet Z Series — Service Manual

Software Troubleshooting
 Reduce resolution in driver by selecting a lower printmode (Best or normal
instead of Max Detail).
 In the Advanced tab of the driver, select Max application resolution =
300 to reduce the driver resolution while keeping the rest of the
printmode characteristics (number of passes for example).
 Disable the Print Processor module in the PCL3GUI driver, which is
responsible for generating EMF. You can do this by going to the
Advanced tab of the driver and disabling the Advanced Printing
Features. The trade-off is that you cannot use the following features in the
PCL3GUI driver: Preview, rotation, scaling, Office features, Back to front
printing.
 In the HP-GL/2 driver, do not use preview or back to front printing to
avoid generating EMF files.
 Use a RIP or a PS model
Limit for Windows 2000 spool file size is smaller (200MB).
Observation: Customer might report that when choosing preview, the job is
not printed but it is printed when he does not select the preview setting. The
cause of the problem might be related to the fact that the HP-GL/2 driver will
use EMF if you do a preview so this limitation applies in this case.
When the image needs to be rotated, parts of the
image might be clipped or disappear
Versions affected: Any application in Windows
Drivers affected: Drivers that use EMF spooling, like the PCL3Gui driver for
the Z Series
Description:
When the image is rotated, sometimes part of the image is clipped. We
have seen this in several applications like Photoshop or Acrobat. In other
cases, instead of clipping the end of the image, the symptom is that some
objects inside the image disappear, we have seen the effect in Acrobat.
Corrective Action
 If possible, rotate inside the application instead of in the driver
 Reduce resolution in driver by selecting a lower printmode (Best or normal
instead of Max Detail)
Remember that if the image is wider than the paper loaded, the image will
be automatically rotated. If possible rotate the image inside the application
instead of letting the driver rotate it automatically when it does not fit.
Driver version available in Fall‟08 will improve the
performace when printing big files or rotating images.

When creating a custom page size, the image is printed in letter size. The
difference between this limitation and the pixels limitation is that in this case
you have a reduction of size both in length and in width. In the case of the

 Get the latest CS3 patch
 Create custom page sizes with bigger lengths than widths and then select
the landscape option if needed.
Latest drivers do not allow creating page sizes with bigger
widths than lengths.
 Select the page size settings inside the File –Print menu instead of the File

Advanced tab of the driver and disabling the Advanced Printing
Features. The trade-off is that you cannot use the following features in the
PCL3GUI driver: Preview, rotation, scaling, Office features, Back to front
printing.
In the HP-GL/2 driver, do not use preview or back to front printing to
avoid generating EMF files.
 Use a RIP or a PS model

Versions affected: CS and previous
Drivers affected: All
Corrective Action
 Reduce image resolution in Photoshop (Image –> Image Size)
 Use a RIP to print the file
Image will be clipped if it is longer than 32768 pixels
Versions affected: All except CS2. Illustrator or Indesign have similar
limitations.
Drivers affected: PCL3GUI drivers
Description:
If the page size to be printed is bigger than 32768 pixels in any direction
(215 pixels), the image will not be completely printed. The number of pixels
depends on the driver resolution:
 At 1200dpi you can print 27.31‖ (69cm). This is equivalent to Max
Detail in the Z2100/Z3100 driver
 At 600 dpi you can print 54.61‖ (1.39m). This is equivalent to Best in the
Z2100/Z3100 driver
 At 300 dpi you can print 109.23‖ (2.78m). This is equivalent to Fast or
Normal in the Z2100/Z3100 driver
Corrective Action
 Reduce resolution in driver by selecting a lower printmode (Best or normal
instead of Max Detail)
 Convert the image to PDF and print from Acrobat, or use a RIP
 Print from CS2. CS2 allows printing 231pixels, which results in lengths of
kilometers.
 Reduce the image size so that it is inside the limits that can be printed

It is not possible to print longer than 109inches
Versions affected: All
Drivers affected: PCL3GUI drivers
Description:
Files longer than 109inches will be clipped. The reason is:
 Illustrator does not take into account the raster resolution from the
application when printing on raster devices, and it always takes 300dpi,
which is the driver resolution, to create the spool file. Therefore it limits the
maximum printable document size to 109inches (32.700pixels/300dpi)
 InDesign has different settings to handle resolution (full resolution,
optimized resolution or screen resolution). For all cases, the spool file
includes 300dpi data so the maximum length is also 109inches
Corrective Action
 Use a different application
 Use a RIP or a PS printer

Print Quality Troubleshooting
Print Quality Troubleshooting Actions
For some Print Quality problems, a Call Agent can try and
troubleshoot the Printer by requesting the Customer to
perform certain actions. Using this process, most problems
can resolved without the need of an on-site visit.
When faced with a Print Quality problem, perform the following actions in
order to resolve the problem:
1 Printer Configuration:
 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).
If you load a sheet without using the skew check feature,
the printer automatically estimates the paper length to be 4
times the width. If skew check is not used, the View Loaded
Paper option will only reflect the estimation made by the
printer, and not the real length.
 Make sure that the correct Print Quality settings are used for different
types of print content.
 Dry time should be set to ―Optimal‖.
2 Perform Printhead recovery (Main Menu/Image Quality Maintenance/
Clean Printheads).
3 Media:
 Make sure that HP or HP-approved media is being used.
 When loading the media, make sure to use the skew check feature
whenever possible (skew check is not available for some types of media).
4 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).
5 Check if the latest version of the firmware is installed. If not, install the latest
firmware revision.

The Service Image Quality Diagnostic Print
The Service Image Quality Diagnostic Print
What is the Service Image Quality Diagnostic Print?
The Printer contains an internal Image Quality Test which helps you to
diagnose the possible source of any image quality defects. The Service IQ
Diagnostic Print is available in the following options:
1 Image Quality Service Best Plot. This plot helps you to diagnose in more
detail the possible source of any image quality defects. It is accessible
through the Service Utility Menu.
The Image Quality Service Best Plot uses the Best Print Mode and is divided
in to three parts as follows:
 Diagnostic Part 1: Printhead Reliability Test. The purpose of this test is to
identify which Printhead is faulty.
 Diagnostic Part 2: Printhead Alignment Test. This test is designed to check
any color-to-color and bi-directional misalignment the printer may have.
 Diagnostic Part 3: Printheads and Paper Advance test. This test is
designed to check whether the Printheads and the Media Advance
Mechanism are working correctly.
2 Image Quality Service Normal Plot. This plot is the same as the Image
Quality Service Best Plot but uses the Normal Print Mode.
3 Advanced Diagnostic Plot. These tests provide more information of the IQ
defects that we could find in the Image Quality Service plot. For more
information, refer to page 1-29, The Advanced Diagnostic Prints.
Designjet Z Series — Service Manual

The Service Image Quality 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

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.
Designjet Z Series — Service Manual
1-24
Reading the Diagnostic Print Results
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

Alignment Test will show something like this:
2 If the Printer is experiencing vertical misalignment problems, the Alignment
Test will show something like this:
3 If the Printer is experiencing bi-directional misalignment problems, the
Alignment Test will show something like this:
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.



Designjet Z Series — Service Manual
1-27
Reading the Diagnostic Print Results
 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 137

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.

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.
Designjet Z Series — Service Manual
1-33
Reading the Advanced Diagnostic Print Results
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 4-6.
Visual Alignment Diagnostic
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.

 If any of the printheads are misaligned beyond the ±1 dot row range,
perform a Printhead Alignment. see Aligning Printheads, Page 1-66
 If a Printhead Alignment does not correct the problem, replace the bad
printhead.
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. The best alignment calibration is obtained using HP

in them.
b Inspector measuring tool test plot.
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.

Print Quality General Advice
1 To achieve the best performance from the printer, only genuine HP
accessories and supplies should be used.
2 Make sure that the paper type selected in the Front Panel is the same as
the paper type loaded into the printer and selected in your software.
3 Make sure to use the most appropriate print quality settings for your
purposes. A lower print quality is likely to be seen if the print quality slider
has been moved to the Speed end of the scale, or the custom quality level
set to Fast.
4 Check that the environmental conditions (temperature, humidity) are within
the temperature/humidity range as specified for the Printer and customer
substrate (refer to the User’s Guide for more information).
5 Check that the ink cartridges and printheads have not exceeded their
expiration dates.
6 Avoid touching the paper while printing is in progress.

3 Check that the appropriate print quality settings are being used (refer to the
User’s Guide for more information). Select the custom print quality options in
the Print dialog, and try turning on the More passes option. Reprint the
job in case the problem has been solved.
4 If you are using a Z3200 series printer, you can reduce grain by turning off
or reducing the amount of gloss enhancer. You can do this through the
Printer Utility, see the Users Guide for more details.
5 Check the Printhead alignment status. If the status is PENDING, perform the
Printhead Alignment (Main Menu/Image Quality Maintenance/Align
Printheads). After alignment reprint the job.
6 Check the paper advance calibration status. If the status is PENDING,
perform the paper advance calibration (Main Menu/Image Quality
Maintenance/Paper Advance Calibration/Calibrate Paper Advance).
7 After Paper Advance Calibration, reprint the job.
Paper is not Flat
Description of problem
If the paper does not lie flat when it comes out of the Printer, but has shallow
waves in it, you are likely to see visible defects in the printed image, such as
vertical stripes. This can happen when you use thin paper that becomes
saturated with ink.
Designjet Z Series — Service Manual

Troubleshooting Print Quality Problems
Shown below is an example of what you might see if you have problems
with the paper not being flat:
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 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.
3 Check that the environmental conditions (temperature, humidity) are within
the temperature/humidity range as specified for the Printer (refer to the
User’s Guide for further information).
4 Select a paper type that is slightly thinner than the paper you have loaded;
this will persuade the printer to use less ink. Here are some example paper
types in ascending order of thickness:
 Plain Paper





Coated Paper
Heavyweight Coated Paper
Fine Art Paper
Super Heavyweight Plus Matte Paper
Thick Fine Art Paper (>250 g/m²).
If your paper type has different versions in the front panel with more and less
ink, select the one with less ink.

Troubleshooting Print Quality Problems
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 Alternatively, leave a sheet of paper in the basket so that freshly
printed sheets do not make direct contact with the basket.
Marks on the Media
Marks on the paper can come in a variety of forms, including horizontal
smears, pinchwheel marks, starwheel marks, and ink marks on the back of
the paper.
Ink marks on the back of the paper
This can happen after a lot of border less printing, especially with nonstandard paper sizes. Also, loading media without skew check frequently
leads to printing on the platen. 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.
 You can also load and unload a sheet of paper 3 times or until clean.
Horizontal Smears on the Paper
Horizontal smears on the paper occur when the printheads touch the paper
and smear the image. In extreme conditions the customers print can look like
the image below where the printheads have actually come into contact with
the media and scraped off the ink. This problem can happen for different
reasons, and will mostly depend on the following factors:
 The type of paper used
 The printmode selected

Corrective Action
1 Whenever you notice this problem, cancel the printing job immediately.
Press the Cancel key and also cancel the job from your computer
application. Soaked paper can damage the printheads.
2 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).
3 Use a recommended paper type and the correct print settings.
4 If using sheet paper, try rotating the sheet 90 degrees. The orientation of the
paper fibers may affect performance.
5 If you are using sheet media, load the media with skew check enabled if it is
possible (skew check might not be suitable for some papers due to the way
they are manufactured or cut).
6 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 touch the paper and smear the image. Try using a heavier paper type,
like HP Heavyweight Coated Paper, HP Super Heavyweight Coated Paper
or thicker Digital Fine Art papers that can absorb ink without expanding.
7 Select a paper type that is slightly thinner than the paper you have loaded;
this will persuade the printer to use less ink. Here are some example paper
types in ascending order of thickness:
 Plain Paper


Troubleshooting Print Quality Problems
If your paper type has different versions in the front panel with more and less
ink, select the one with less ink.
8 Try to increase the margins by relocating the image to the center of the page
with the software application being used.
9 If horizontal smearing occurs when you are using Photo Gloss or Semi-Gloss
papers, try setting the carriage position to HIGH. To set the carriage
position to HIGH, create a custom paper type according to the following
procedure:
a From the HP Easy Printer Care (Windows) or HP Printer Utility (Mac OS),
create a custom paper type based on the paper type that resulted in
horizontal smears (for Photo Gloss or Semi-Gloss papers ONLY). For
more information on creating custom paper types, see the User´s Guide.
When you name the paper type, it is a good idea to use the
paper‟s commercial name and something indicating the
high carriage setting.
b Go to Change Printing Properties and select the paper that you just
created.
c Change the paper thickness to the highest setting.
d Select the custom paper type from the Front Panel and align the
printheads (see Aligning Printheads, Page 1-66)
e Check that the custom paper type is selected from the Front Panel and
perform a Color Calibration.
f If the customer prints with ICC profiles, create a new ICC profile.
g Try printing the project again using the new custom paper with the
carriage position set to HIGH.
10 If the horizontal smearing occurs when you are using Digital Fine Art paper,
the cause of the problem may be the environmental conditions. Check that
the humidity and temperature are within specifications for both the printer
and the paper.
11 If the humidity and temperature are OK, install the Extra High PRS Wedge.
The Extra High PRS Wedge increases the distance between the printhead
and the paper and can help eliminate horizontal image smearing problems.
The new Extra High PRS Wedge can be ordered using Part
Number Q5669-67055. For the relevant removal and
installation procedures, see page 6-109.

Troubleshooting Print Quality Problems
Pinchwheel Marks
Pinchwheel marks are caused by the pressure of the Pinch Roller on the
paper before printing the image. These are vertical marks that go through
the entire plot and are more or less visible depending on the contents of the
plot.
Corrective Action
1 The cause of the Pinchwheel marks may be the environmental conditions.
Check that the humidity and temperature are within specifications for both
the printer and the paper.
2 If the printer is a Z2100/Z3100/Z3100ps, install the new Rubber
Pinchwheel Kit. The new Pinchwheels are made of rubber material, greatly
improving printer performance and eliminating Pinchwheel marks.
The new Rubber Pinchwheel Kit (for the Z2100/Z3100/
Z3100ps printers) can be ordered using Part Number
Q5669-67060. For the relevant removal and installation
procedures, see page 6-200.
The Z3200 series already uses rubber pinchwheels, so this
solution does not apply to the Z3200 series.
Rear Tray Marks
Rear Tray Marks are vertical marks that appear when using thick sheet
media and loading it with the rear tray path. Although they appear similar
to pinchwheel marks, they are not the same and can be diagnosed:
 Rear tray marks are 3 cm wide. Pinchwheel marks are 1.5 cm wide.
 Rear tray marks are 4-10 cm apart. Pinchwheel marks only 1 cm apart.
 The texture of a rear tray mark is very irregular, whereas pinchwheel
marks are more consistent.
 For a 24 inch plot, you will see 1-5 rear tray marks. For a 44 inch plot,
you will see 1-9 rear tray marks. If you see more marks than that, it is
likely that they are pinchwheel marks.
Corrective Action
1 Load the media using the roll path instead of the rear tray path. Use the
black hub of the spindle to align the sheet. Even if you use the roll path, you
Designjet Z Series — Service Manual
1-48
Troubleshooting Print Quality Problems
should specify that you are loading a sheet to avoid print quality problems.
Starwheel Marks
Starwheel marks are caused by the pressure of the starwheels on the paper
just after the plot is printed. These are vertical, non-continuous marks that are
more visible in dark areas of the plot..
Corrective Action
1 If the printer is a Z2100/Z3100/Z3100ps, install the new Starwheel
Assembly (with Actuator). The new Starwheel Kit tilts the Starwheel Rail,
increasing the distance between the active starwheels and the paper and
reducing Starwheel marks.
The active Starwheels are located over the Starwheel Roller, and the
passive Starwheels are located inside the print path. The new Starwheel
Assembly (with Actuator) reduces active Starwheel marks, but does NOT
reduce passive Starwheel marks.
The new Starwheel Assembly (with Actuator) (for the
Z2100/Z3100/Z3100ps printers) can be ordered using part
numbers Q5669-67061 (24 inch) or Q6659-67016 (44 inch).
For the relevant removal and installation procedures, refer
to page 6-164.
The Z3200 and Z2100 Revision C series have an automatic
starwheel that can be controlled through the printer utility
(Z3200) or the front panel (Z2100 Revision C).
2 If the printer is a Z3200/Z3200ps or Z2100 Revision C, you can raise the
starwheels to the UP position semi-automatically. See the User´s Guide.
Designjet Z Series — Service Manual
1-49
Troubleshooting Print Quality Problems
3 For the Z2100 (revision a or b)/Z3100/Z3100ps printers, activate the UP
position of the new Starwheel Assembly (with Actuator) on the left side. Slide
the left actuator away from the Starwheel Assembly (the UP position).
4 Activate the UP position of the new Starwheel Assembly (with Actuator) on
the right side. Slide the right actuator away from the Starwheel Assembly
(the UP position).
Dark Ink Marks on the Media due to cockle
They appear when the media advance is not properly controlled and so the
carriage interferes with it (cockle). These marks can appear at the edges of
the media (in the beginning of the plot) or at any other position in the plot.
Corrective Action
1 If the starwheel position has been set to HIGH with the printer utility, set the
starwheel position to DOWN again (use the actuators for the Z2100/
Z3100/Z3100ps, the Printer Utility for the Z3200, or the front panel for
Z2100 Revision C). Although starwheel marks will be more visible, it should
fix the ―dark ink marks on the media‖ problem.
2 If using a roll that is close to its end, it could be that there is to much curling
and it is not being well controlled by the Starwheels. A recommendation in
this case would be setting the starwheel position to the DOWN position (use
the actuators for the Z2100/Z3100/Z3100ps, the Printer Utility for the
Z3200, or the front panel for Z2100 Revision C) and trying to remove

Troubleshooting Print Quality Problems
curling by, for example, leaving the media loaded on the machine during
the night to "straighten" it.
3 If the problem continues after you have set the starwheel position to DOWN,
the problem could be the Carriage Assembly, the Starwheel Rail, or the
Starwheel End Support. Check to see if they are damaged or need to be
replaced.
Problems with the Edges of objects
Stepped or not sharp
The edges of objects or lines appear to be poorly defined or lighter in
density than expected.
Corrective Action
 Make sure that the Print Quality slider is set to Quality, and that More
passes and Max detail are set to OFF.
Darker than expected
The edges of objects seem darker than expected.
Corrective Action
 Make sure that the Print Quality slider is set to Quality, and that More
passes and Max detail are set to OFF.
Bronzing
When printing on photo paper with gray and black ink only a gloss
differential problem can be encountered when light is directly reflected from
the print, producing 'bronzed' reflections where ink has been laid.
Corrective Action
If the printer is a Z2100:
 Use the full set of inks option when printing greyscale images.
If the printer is Z3100/Z3200:

Troubleshooting
 If using standard print quality options, ensure that the slider is set to
Quality.
 If using custom print quality options, ensure that the Gloss enhancer
option is set to Whole page. You can also try Economode.
 Make sure that the correct paper type is selected in the front panel and
the driver or software of the customer.
If the printer is a Z3200 only:
 -Increase the amount of gloss enhancer used.
As general advice for all models, and as last resource, display the print
vertically or behind a glass.
Black and white prints do not look neutral
Consider printing in grayscale (color options submenu inside the printing
preference menu). See the User´s Guide for more information.
 For all printers, check that the Advanced color options for grayscale
printing in the driver are not being used to modify the neutrality of the
grayscale prints.
 If the customer is already printing in greyscale, and the printer is a
Z2100, select ―Print with Black and Grey Inks Only.‖
Horizontal lines at the end of a cut sheet print
There is a type of defect that only affects the end of a print, within
approximately 30 mm of the trailing edge of the paper. Some very thin
horizontal lines may be seen across the print.
Corrective Action
1 Print the Service Image Diagnostics Print, and clean any printheads that
need cleaning. Reprint the job in case the problem has been solved.
2 Try printing with roll paper.
3 Try using larger margins around the image.
Vertical lines of different colors
The print has vertical bands of different colors along it.
Corrective Action
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).
3 If you have already set it to Quality, try selecting Custom Options and
then More Passes.

Troubleshooting Print Quality Problems
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.
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. Check
that the paper type you have loaded corresponds to the paper type selected
in the front panel and in your software.
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 If you are using application-managed colors, check that the color profile you
are using corresponds to the selected paper type. If you are working with
non-HP papers, you might need to create an ICC Profile. If you have doubts
about which color settings to use, or you want to create an ICC profile, see
the users guide.
Designjet Z Series — Service Manual
1-53
Troubleshooting Print Quality Problems
6 If you select application-managed colors in your application and printermanaged colors in the printer driver, your results will be wrong. You should
manage colors in the application or in the printer, but not in both.
7 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.

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 Ink Cartridges provide ink to the Printheads. The color Ink
Cartridges supplied with the printer have a capacity of 69ml but optional
130 ml cartridges are also available.
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.

General Precautions When Handling Ink Supplies
Use the following precautions when handling Ink Supplies:
Do not touch, wipe or attempt to clean the printhead
nozzles. This can damage the printhead.
 Handle the ink supplies with care. In particular the Printhead, which is a
high precision device and must be handled carefully.
 Do not touch the Printhead nozzles.
 Do not put the Printhead down on the nozzles.
 Do not be rough when handling the Printheads. Always set them down
gently.
 Do not drop the Printheads.
 Proper handling will assure optimum performance throughout the
Printhead life.
 Do not touch the end of the Ink Cartridge which is inserted into the printer
as there may be a small amount of ink on the connection.
 Avoid storing partially used Ink Cartridges on their ends.
When Should You Replace the Ink Supplies?
When to change the ink supplies is mostly determined by you with guidance
from the front panel. In conjunction with the messages displayed in the front
panel and the message explanations in this chapter, you will be able to
choose for yourself when is the right time to change the ink supplies.
The Printer will also display the ink level and will tell you when the ink supply
is low on ink. This means you have constantly updated information about the
ink supplies.
Ink Cartridge Levels, Information, and Replacement
Ink Cartridge Levels
Trough out this chapter all the example Front Panel screens
are for the Z2100 Photo Printer unless otherwise stated.
The front panel displays Ink Levels shown as level bars. These bars represent
how much ink is remaining in the Ink Cartridges: as ink is used up the bars
get shorter in length.
There are two methods for checking the ink levels of your Ink Cartridges.

The printer will start checking and preparing the printheads. The default
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, and roll or sheet media loaded with skew check is
preferable to loading media without skew check. If
possible, always avoid loading media without skew check.
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.

Ink Supplies Troubleshooting
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
strong light source near the printer during printhead realignment can affect
alignment.

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.


Ink Supplies Troubleshooting
 Printhead health problems, clean printheads.
 The alignment was done with the transparent window open, repeat the
alignment with the window closed.
If the problem persists after using valid paper, cleaning the printheads, and
keeping the window closed, there may be a Failure in the scanning system
needing reparation or the printheads, although clean, may not work and
need to be replaced.

Solving Ink Supplies Problems
Most of the problems that you could encounter when working with the ink
supplies are solved with guidance from the front panel. A full list of front
panel messages are supplied in the User’s Guide.
You Cannot Insert the Ink Cartridge Into the Printer
1 Ensure that you have the correct cartridge number for your printer. Z2100/
Z3100 printers use hp no.70 supplies, while the Z3200 uses hp no70
supplies for all colors except red, which is no.73.
2 Ensure that the Ink Cartridge is the correct color for that slot.
Designjet Z Series — Service Manual

Ink Supplies Troubleshooting
3 Ensure that the Ink Cartridge is the correct orientation, with the color coded
label at the top.
Never clean inside the Ink Cartridge slots as this can cause
damage to the Printer.
You Cannot Insert the Printhead Into the Printer
1 Ensure that you have the correct cartridge number for your printer. Z2100/
Z3100 printers use hp no.70 supplies, while the Z3200 uses hp no70
supplies for all colors except red, which is no.73.
2 Ensure that the printhead is the correct color for that slot.
3 Ensure that the printhead is in the correct orientation.
4 Ensure that the protective cap is removed from the Printhead.
The front panel says to reset or replace a printhead
1 From the front panel, turn the power off then on.
2 Check the front panel display message, if it shows the ready message, the
printer is ready to print. If the problem remains continue with the next step.
3 Remove the printhead.
4 Clean the electrical connections on the backside of the printhead with a lint
free cloth. You can carefully use a mild rubbing alcohol if moisture is needed
to remove residue. Do not use water. You can use the Flex Contacts Cleaning
Tool.
This is a delicate process and may damage the printhead. Do not touch the
nozzles on the bottom side of the printhead, especially not with any alcohol.
5 Reinsert the printhead.
6 Check the front panel display message. If the problem remains, try a new
printhead.
Designjet Z Series — Service Manual

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 Flex Contacts Cleaning Tool
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.
Designjet Z Series — Service Manual
1-72
Ink Supplies Troubleshooting
The flex contacts cleaning tool is available as a service part for the Z2100/
Z3100 Photo Printer. It contains replacement sponges and an instruction
sheet, and 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 Flex Contacts Cleaning Tool.
Do not touch, wipe or attempt to clean the printhead
nozzles. This can damage the printhead and reduce print
quality.

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.
