Guide to Troubleshooting the Printer
Introduction
This chapter will guide you through the relevant steps to take when
troubleshooting the Printer.
Phone Support
In certain circumstances, a Call Agent can try and troubleshoot the
Printer by requesting the Customer to perform a Service Calibration,
Test or Utility via the phone. Using this process, it can be
determined whether the Printer requires any on-site maintenance.
Which Firmware Version Relates to Which Ink System
A.01.XX - This firmware revision allows the Printers to only use
Imaging Inks.
A.02.XX - This firmware revision allows the Printers to use both
the Imaging Inks and the UV Inks.
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.
NOTEWhen reporting the System Error Code, make sure that you
supply the full Error Code (inclu ding the last 8 numb ers where
applicable) and the firmware version as well as the status of the
Printer when the Error occurred (was it printing, calibrating,
processing, etc...). Without this information, HP Support
Personnel cannot help you.
NOTEWhen reporting the Error Code, make sure that you supply the
full Error Code and the firmware ve rsion (d ispl ayed durin g the
initialization process when powering ON the Printer or available
in the User’s Printer Setup ⇒ Utilities ⇒ Statistics menu).

HP DesignJet 5000 Series Printers Service Manual
Troubleshooting
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.
NOTEIf 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.
Performing the Necessary Service Calibrations
Is the Printer calibrated correctly after replacing a component?
Refer to the table on Page 5-2 to determine when a calibration is
required.
NOTERemember that certain Calibrations are required even if an
Assembly has been disassembled to gain access to another
Assembly or Component.
For information on the Service Calibrations and how to use them
see 5, Service Calibrations.
Troubleshooting Calibration Error Codes
Chapter 5 - Service Calibrations - contains a list of Error Codes that
are reported when a Calibration fails.
Calibration error codes consist of a four digit number [XXXX].
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.
HP DesignJet 5000 Series Printers Service Manual

Troubleshooting
Troubleshooting Ink Supplies Error Codes
Chapter 3, HP Ink Supplies Tr oubleshooting, contains a list of Error
Codes that are reported for Ink Supplies i.e. Ink Cartridges,
Printheads and Printhead Cleaners. The error codes are described
and recommended corrective actions are provided. Only try one
recommended action at a time and check if the error code has
disappeared.
Ink Supplies error codes consist of a four digit number [XXXX].
Chapter 4 - Service Tests and Utilities - describes the Printer
initialization sequence and reports errors that may be reported when
Printer initialization is performed.
Self Diagnostic error codes consist of seven alphanumeric
characters [XXXXXXX].
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:
n Which firmware revision the Printer is using.
n The complete error number.
Solving Image Quality Problems
Whenever an Image Quality problem appears, it is advisable to print
the Diagnostic Print. This will help you differentiate between
possible Printhead errors and other problems such as incorrect frontpanel selection, driver or RIP configuration or mechanical
problems. For information on solving Image Quality problems see
Chapter 6, Print Quality.

Troubleshooting
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. Remove the DIMM’s Cover (See
⇒ Page 8-75) and check the green
and red Status LED’s on the Main PCA. If they are both NOT lit,
replace the Power Supply Unit ⇒ Page 8-83.

Troubleshooting
ALL the Front-Panel LEDs are Lit but Nothing Else
Happens
The BootROM DIMM is NOT correctly installed or is th e wrong ty pe.
1. Power OFF the Printer from the back and disconnect the Power
Cord. Reseat the BootROM DIMM (looking from the rear of the
Printer, the first slot from the left - See
that it is installed correctly.
⇒ Page 8-75) making sure
NOTE
2. If the problem persists replace the BootROM DIMM For more information, refer to “Electronics Problems” on page 1-21.
⇒ Page 8-75.
Troubleshooting Media Jams/Printhead Crashes
NOTEIf using HP Coated Media when problem occurred, please also
refer to Page 1-11.
The failure modes “media jam” and “head crash” are grouped
together because in many c ases a me dia ja m cause s the m edia to li ft
up into the carriage path and cause a head crash, thus causing many
media jam failures to be reported as head crashes.
1. Did the media jam occur when loading media?
n 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.
NOTEWhen clearing a media jam, sometimes media is stuck in the
paper path. T o 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.
1-6
2. Is the customer using non-HP media?
n
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. The Carriage is at the incorrect height in relation to the Center
Platen. Adjust the carriage to the correct height ⇒ Page 5-18and try
to load the media again.
4. Check that the Vacuum Fans work correctly - Refer to Page 1-10,
Problems with Vacuum .

Troubleshooting
Troubleshooting Shutdowns - User Message
"Warning: Switch Power Off"
If a shutdown occurs, you will get the message “Warning: Switch
Power Off” followed by:
n Check Printhead Cleaner Path.
n Check Paper Path.
n Check Printhead Path (followed by (1), (2) or (3)).
A shutdown in each path will require different steps to resolve the
problem as explained as follows.
WARNINGIn each case, make sure that you power OFF the Printer be fore
attempting any procedures to resolve the problem.
Check Printhead Cleaner Path
This message appears whenever the Service Station Carriage does
not move, either because of a bad cable connection, a defective
motor or because of some obstacle inside the Service Station.
n
If the Printer is
new
, check that the Service Station cable (which is
the grey flat cable with the grey connector) is plugged into the Main
PCA. Make sure that the clips of the conn ector are closed
completely. Check also that the Service Station cable is not damaged.
n In already used Printers, power OFF the Printer and try to move
the Service Station backwards and forwards to see whether it is
blocked. Possible causes are: Printhead Cleaners incorrectly
positioned, damaged or, even, pieces of paper within the Service
Station. Remove the Printhead Cleaners or the pieces of paper
and check whether the problem persists.
n
If the problem disappears without the Print head Cleaners, reinsert them
into the Service Station and see whether the problem reappears. If the
problem reappears, replace the complete set of Printhead Cleaners.
n
If the problem persists even without the Printhead Cleaners, then
replace the Service Station (⇒ Page
8-67
) and recalibrate the Printer.

Troubleshooting
Check Paper Path
This warning appears whenever the friction on the Paper -A xis is too
high: the electrical current needed by the Paper-Axis Motor to move
the paper is too high, so before burning the motor or the Main PCA,
this warning appears. The commo n reason for this error is a n internal
paper jam or at the end of a roll of media the paper is glued to the
media core. It can also be due to a defective motor or Main PCA.
n Check that there are no pieces of paper left inside the Printer,
especially if it happens after a paper jam.
NOTEOne way to verify this easily is to take a rigid sheet of paper and
move it along the paper path with the media load lever lifted.
n Also, check that the customer has inserted the spindle hubs
completely, otherwise they may rub against the side plate and
increase the friction.
n If the error still persists, check that the Paper-Axis Motor cables
are connected correctly and that they are not damaged.

Check Printhead Path (1)
This warning appears whenever friction on the Scan-Axis is too
high: the electrical current needed by the Scan-Axis Motor to move
the Carriage is too high, so before burning the motor or the Main
PCA, this warning appears. The usual reason for this error is an
internal paper jam, an obstacle in the Printhead path, a broken belt,
badly installed Ink Supply Tubes, etc.
n Apply Oil along the complete axis of the Slider Rods with the
User’s Slider Rods Lubrification Kit ⇒ Page 9-8.
n Also, switch OFF the Printer and move the Carriage from side to
side to verify that it moves smoothly.

If the Printer still fails, check that the Scan-Axis motor is connected
correctly to the Main PCA and that the cable is not damaged.
n If the error remains, replace the Belt (⇒ Page 8-46) or the Scan-
Axis Motor ⇒ Page 8-55.

Also, after re placing the Scan -Axis Motor, perform the Sc an-Axis Test
(⇒ Page
n If the Printer still fails, replace the Main PCA ⇒ Page 8-79.
Check Printhead Path (2)
4-10) and check that the values are within the given limits.
This is a safety shutdown and occurs whenever there is a discontinuity
in the Printhead path, because of an obstacle, oil drops on the Encoder
Strip, the Carriage cover touching the tube guides, etc.
n Switch OFF the Printer and move the Carriage from side to side
to verify that it moves smoothly.
n If it still fails, check the Encoder Strip and, if necessary, clean it.
Check Printhead Path (3)
This is always caused by high friction in the Printhead path. Only in
very special cases, when it happens inside the Left Hand Cover,
incorrect assembly of the tube system causes it.
n Apply Oil along the complete axis of the Slider Rods with the
User’s Slider Rods Lubrification Kit
⇒ Page 9-8.
Replace Message "xx15 Replace" and "xx16 Replace"
In certain circumstances (e.g. Printhead crash without Printer
shutdown), the message "xx15 Replace" or "xx16 Replace" may
appear on the front panel. This is due to a temporal disconnection
between the Printhead and the flex circuit in the Carriage Assembly.
n
Clean the Printheads and the Carriage interconnects (refer to page
Carriage Interconnect Wiper
9-6,
) and reseat the failing Printheads.

Troubleshooting
Problems with Vacuum
If you have problems loading either Roll or Sheet Media, then there
could be a problem with the Vacuum Fan or Booster Fan. To verify
if there really is a problem with Vacuum, try the following:
1. With the Printer ON, open the Window of the Printer and place a
sheet of HP High Gloss Photo Paper (must be D-Size), aligned with
the blue lines on the Center Platen. If the Vacuum holds the sheet in
place, and then loads it correctly , then the Fans function correctly. If
the Vacuum does not hold the sheet in place (no suction), then try
the following:
n Check that the holes in the Center Platen are NOT blocked.
n
Clean the Overdrive using the Platen Cleaning Utility ⇒ Page
n Check that the Vacuum and Booster Fans are installed correctly.
n Replace the Vacuum Fan ⇒ Page 8-98.
n Replace the Booster Fan ⇒ Page 8-103.
2. If the Vacuum held the sheet in place, but couldn’t correctly load it,
then there could be a problem with the Overdrive. In this case,
replace the Center Platen Assembly ⇒ Page 8-112.

At altitudes above 2,000 meters, the vacuum force holding down the
media will be lower, therefore the media will not be held in place
properly causing:
n Ink Smearing on the Media.
n Printhead crashes against the Media.
n Cut Sheet loading problems (high probability).
n Roll Media loading problems (low probability).
To solve the problem, try the following:
n Using the “1.3 Altitude Setup” in the Service Utilities, set the
altitude to “1.3.2 2000 m or more” (see Altitude Setup 4-23).

Printhead Crashes/Smears on High Density Prints
Using Coated Media
High density prints can cause cockle mainly on HP Coated Media.
This causes two main problems:
1. Cockling in the borders - Because the Printer places too much ink
on the Coated Media, the borders of the print become raised,
causing the Printhead to crash against the media. To solve the
problem, try the following:
n Try using Heavy Weight Coated Media instead of Coated Media.
n Change the paper margins to “Extended” in the Printer Setup
menu/Page Format/Margins or in the Driver. If the customer is
printing PostScript images, send them a PPD file containing the
extended margins.
n Use the Deflectors.
n Upgrade the Firmware ⇒ Page 9-11.
2. Cockling within the print - If the Printer places too much ink within
the print, the media starts to ripple, causing the Printhead to smear
against the media. To solve the problem, try the following:
n Never use HP Coated Media for High Density prints. As a
substitute use HP Heavy Weight Coated or Heavy We ight Coated
(Economy) Media.
Color differences in different HP DesignJet Printers
Color differences between one image printed on the HP DesignJet
5000 Series and the rest of the DesignJet platforms are due to the
different chemistry of the 5000 series inks compared with the rest of
the inks for other printers. This color variability among different HP
DesignJet Series Printers has been always present. You can try to
achieve consistent colors with the following:
n Select the same color emulation settings in your Postscript Driver
as the one used by the printer you want to emulate.
n Select the correct Ink Emulation from the Printer Setup Menu/
Internal RIP Settings.

Troubleshooting
Banding at variable extreme environmental conditions
The Accuracy Calibration has been done at normal environmental
conditions, therefore printing in extreme environmental conditions
will cause banding because the advance of the Drive Roller does not
correspond to the same conditions that the calibration was done in.
To solve the problem, try the following:
n Perform the Accuracy Calibration in the new environmental
conditions (Refer to the User’s Guide - Media Solutions).
Banding with unsupported Media
The Accuracy Calibration has not been done for the Media now
loaded. Banding may occur because the advance of the Drive Roller
does not correspond to the same conditions that the calibration was
done in. To solve the problem, try the following:
n Select the Media loaded in the “Media Options” menu and
perform the Accuracy Calibration (Refer to the User’s Guide Media Solutions).
Banding due to Ink Cartridge replacement while
printing
A user has removed the Ink Cartridge while the Printer was printing,
which has caused the Printer to stop. If the user does not replace the
Ink Cartridge immediately, when the Printer starts to print again, a
band will appear in the position where the pri nting resta rted. This is
because the wet ink interacts with the dried ink on the media
causing the band to appear. To solve the problem, try the following:
n Do NOT remove the Ink Cartridge while the Printer is Printing.
Only replace/remove Ink Cartridges in between Prints.
n If the Ink Cartridge was replaced due to the “Empty” status on the
Front Panel, then advise the customer to replace the Ink Cartridge
when the “Very Low” status is showing on the Front Panel.

Hue shift on HP Colorfast Adhesive Vinyl media
Under high humidity conditions (approx. >65%) the colors tend to
fade over time, particularly colors that require Magenta. To solve
the problem, try the following:
n Reduce the level of humidity (<65%) that the Printer is working
in. To find the humidity level, print the Service Configuration
Print (Printer Setup Menu / Utilities / Test prints / Service config).
n Laminate the prints.
Black Smearing on HP Photo Imaging Gloss
Narrow black lines can smear on this type of media, particularly if
the lines are narrow and have white gaps in between them. Try the
following:
n Increase the Dry Time using the Front Panel (Refer to the User’s
Guide).
n Laminate the prints.
Magenta Bleeding on HP Photo Imaging Gloss when
using the Take-Up Reel
Under high humidity conditions (approx. >70%) this media reduces
its capacity to absorb Magenta because of this color’s particular
characteristics. When an area fill with magenta is printed and then
rolled onto the Take-Up Reel the ink that is not completely dry
moves laterally on the media. To solve the problem, try the
following:
n Reduce the level of humidity (<70%) that the Printer is working
in. To find the humidity level, print the Service Configuration
Print (Printer Setup Menu / Utilities / Test prints / Service config).
n Increase the Dry Time using the Front Panel (Refer to the User’s
Guide).
n Do not use the Take-Up Reel or Bin for this media when
humidity levels are high.

Troubleshooting
Loss of Gloss on HP Photo Imaging Gloss when using
the Take-Up Reel
Under high humidity conditions (approx. >70%) the polymer chain
in the coating of this media relaxes and the drying rate decreases. If
the printed media is rolled onto a Take-Up Reel or is covered by
another print, the contact between the two surfaces could cause
blotches in the gloss. Try the following:
n Reduce the level of humidity (<70%) that the Printer is working
in. To find the humidity level, print the Service Configuration
Print (Printer Setup Menu / Utilities / Test prints / Service config).
n Increase the Dry Time using the Front Panel (Refer to the User’s
Guide).
n Do not use the Take-Up Reel or Bin for this media when
humidity levels are high.
Dry Cockle on High Density Prints Using Paper Based
Media
High density prints can cause dry cockle mainly on Paper Based
Media.
To solve the problem do the following:
n Use the Take-Up Reel and Take-Up Reel deflectors.
n Set the Printer to Productivity mode to reduce the ink density.
n Select Coated media modes
If the problem persists, try the following:
n Laminate the prints.
n Use a heavier media that is more suitable to high ink density,
such as HP Paper based Semi-Gloss or HP Poster Paper.

Wrinkles and scratches (cockle) on HP Coated and
Heavyweight Coated Media.
Images may be damaged if prints are not handled with care,
particularly when handling wide plots. This can happen when
images are placed on top of one another and there is movement
between them, causing friction and loss of ink from the surface if it
is not completely attached. Also, if plots are rolled up, wrinkles can
occur. To avoid this problem try the following:
n Always handle plots with care.
n Use of the Take-Up Reel eliminates handling and avoids
wrinkles.
n Use heavier media.
n For Heavyweight Coated media, select faster print modes such as
Heavyweight Coated (Economy) for Media selection, and/or
Productivity Print mode.
n If damage is slight, Lamination will help towhead’ defects.
n Use of Fixative Sprays immediately after printing may protect the
image.
Worm marks (cockle) on part of plots on paper based
media
At high temperatures and under dry conditions, worm marks may
occur on initial parts of plots when printing solid fill areas in
medium tone colors. Try the following:
n Advance the media manually by 15 mm.
n Select Heavy Coated for Media setting.
n Select Productivity mode to reduce ink density.

Drying Time Too Long for HP Studio Canvas
Under conditions of high humidity (> 70%) HP Studio Canvas
retains a high amount of water and takes too long to dry, also
creating problems in using the Take-Up Reel and Bin. To solve the
problem try the following:
n Reduce the level of humidity (<70%) that the Printer is working
in. To find the humidity level, print the Service Configuration
Print (Printer Setup Menu / Utilities / Test prints / Service config).
n Increase the drying time using the Front Panel settings (Refer to
the User’s Guide).
n Do not use the Take-Up Reel or Bin under conditions of high
humidity.
Media Skew when Printing a Banner Plot
When printing banners, media skew occurs. This is particularly
noticeable in the first plot when media is not perfectly aligned. To
solve this problem do the following:
n Use extended margins for banner plots (Refer to the User’s
Guide).
User message "Media loaded incorrectly. Remove
media"
This message appears when the media sensor has detected media,
but the line sensor has not detected the leading edge of the media at
all or has found it in an incorrect position.
There are three possible situations when this message comes up:
1. The paper is in the incorrect position because the Printer was turned
OFF in the middle of a print. It should only happen in printers
without the Take-Up Reel (42" model), because with the Take-Up
Reel installed the Printer will not search for the leading edge after
the Printer has been powered-up or after activating the media load
lever. The Printer simply continues to print wherever it stopped.
n To verify this setting, check in "Printer Setup Menu > Device
setup > TUR installed". It should be set as No for the 42" model
Printers and Yes for the 60" model Printers.

2. The media sensor is defective. T o verify this, remove the media and
re-boot the Printer. If the message comes up during initialization,
the media sensor is defective. To solve this, try the following:
n Check that the media sensor cable is connected correctly
n Check that the media sensor cable is not damaged and that the
media sensor is clipped correctly.
n Replace the Media Sensor ⇒ Page 8-104.
3.
The Line Sensor does not detect the leading edge of the media. To
