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 on page 46 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.).
●
NOTE: 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.
NOTE: 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 Diagnostic Menu on page 73 & Service
Menu on page 124.
Performing the Necessary Service Calibrations
Is the printer calibrated correctly after replacing a component? For information on the Service
Calibrations and how to use them see Chapter 5, Service Calibrations.
NOTE: Remember that certain Calibrations are required even if an Assembly has been
disassembled to gain access to another Assembly or Component.

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
2. If ALL the Printheads are rejected (the status message on th e F ron t Pa ne l do es NOT show "OK"
for ALL the Printheads) then perform the Electronic Module Test
on page 90.
Flex Contacts Cleaning Tool on page 22) and try again.
Refer 3. Electronics Module

What to do if the Front Panel is blank
The LEDs of the formatter (visible through the cover) and the power supply can help you troubleshoot
a problem when the Front Panel is blank.
1. The following image shows the Power Supply LED, looking through the cover.
2. The following image shows the Formatter LEDs, which are marked I, II and III.
Use the following table to interpret the LEDs and find the so urce of the problem. Remember that
▲
you should read these LEDs when you push the Power button. Some combinations may require
the replacement of two or more components. In th is case, always replace one component at a time.
Test the printer to see if the problem has disappeared (ch eck the LEDs again). If the same LED
sequence continues, replace the next component indicated in the table.

Cover Sensors are not Working
1. Perform the Sensors Test Refer 5. Sensors on page 101.
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. The Line Sensor is not calibrated correctly. Perform the Line Sensor Calibration
Sensor Calibration on page 146.
Electronics Module (Main

Refer Line
3. The Line Sensor is damaged or faulty. Replace the Line Sensor
Line Sensor on page 267.
Problems with Color Accuracy
The Color Sensor (ESP) is a powerful tool unique to the Z series printers to maintain color accuracy. If
you notice any problems with colors, perform the Color Sensor (ESP) calibration. Refer to
(ESP) Calibration on page 149.
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 causin g 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.
NOTE: 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 p ap er pa th t o push ou t th e media
that is still stuck there.
2. Is the customer using non-HP media?
Color Sensor
The use of non-HP media can easily be the cause of media jams and head crashes (espec ially
●
head crashes because HP media is specially formulated to avoid cockle, one of the primary
causes of head crashes). If the media is not HP approved, advise the customer to use HP
media and check to see if the problem is now solved.

Banding at variable extreme environmental conditions
Since the Accuracy Calibration has been done at normal environmental conditio ns, printing in extreme
environmental conditions will cause banding because the advan ce of th e Media Advance Roller does
not correspond to the same conditions that the calibra tio n was done in. To solve the problem, try the
following:

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.
Always load sheet media using the Rear Input Tray. Do NOT load the media as you would load
roll media.
It must be loaded with the right-hand edge against the blu e line on th e Prin t Platen.
The media may be crumpled or warped or may have irregular edges.
If hand-cut media is used, the edges may not form a right-angle or they may be rough. If possible,
hand-cut media should not be used. Only purchased sheet media should be used in the Printer.
If you have problems with paper jams, check that the Overdrive is not obstructed by bits of paper

What are Ink Supplies?
For each of the ink colors used in the printer, there are two components, th e Printhead and Ink Cartridge.
These components are called Ink Supplies.
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 and 30 0 ml are also ava ilab l e.
The Ink Cartridges 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 high quality printing results that 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 high quality printing results even when the ink levels are getting low.
The front panel displays the status of the Ink Cartridge. Using the front panel, detailed information can
be checked on the Ink Cartridges.

Printheads
The Printheads are extremely durable an d d o n ot need to be replaced every time an Ink Cartridge is
replaced. They are independent of the Ink Cartridges and will continue giving excellent image quality
results even if the Ink Cartridges are low on ink.
If you notice a decline in print quality such as lines or dots missing from text/graphics, go to
Troubleshooting Print Quality Problems on page 36.
