Printer education and training

Before any attempt is made to troubleshoot the printer, you must have the relevant training on the HP
Designjet Z6200/Z6600/Z6800 printer series. If you are not trained on these printers, please contact HP
Education or HP Training to enquire about becoming ‘HP Service Qualified’ for this printer.

Firmware update

The first step to take when trying to clear an error with the printer is to check that the firmware installed in
the printer is the latest available. Firmware updates often include fixes for common problems, and simply
updating the firmware can often resolve the problem. New firmware can be downloaded here:

http://www.hp.com/go/designjet/downloads

USB firmware update

If it is not possible to perform a firmware update using the Embedded Web Server (for instance, if the printer
has a System Error and the Embedded Web Server is inaccessible), it is still possible to do it using a USB flash
drive.

1. Turn off the printer.

2. Ensure that your USB flash drive contains a valid FMW firmware file and no other files.

3. Connect the USB flash drive to the USB host port on the Formatter.

4. Turn on the printer and follow the instructions on the front panel.

Forced firmware update

When the printer is started for the first time, it may automatically request a firmware update in order to fix
some known issues. You can respond in one of the following ways.

●

Use the USB flash drive provided in the box with the printer.

When a firmware update is requested, you should find a USB flash drive in the box, containing the new
FMW firmware file. Follow the instructions in the flier accompanying the USB flash drive.

NOTE: The USB flash drive is provided only to update the printer's firmware. No other uses of the USB

flash drive are supported.

NOTE: If the USB flash drive is not in the printer box, or fails to work properly, then download the

firmware instead.

●

Download the FWM firmware file from the HP Web site.

Store the file in a standard USB flash drive with no other files. Connect the flash drive to the formatter's
USB host port to perform the firmware update, following the instructions on the front panel.

●

Skip the firmware update.

If you cannot find the USB flash drive and you have no Internet connection, you can skip the forced
firmware update temporarily by pressing the OK key on the front panel three times, and the printer will
continue with the initialization sequence. Make sure that the firmware update is performed later. The
printer will request the firmware update every time that it starts, until the update is performed.

ENWW Printer education and training 3

Print-quality troubleshooting

Whenever a print-quality problem appears, it is advisable to print the Diagnostic Print to help diagnose the
problem. The Diagnostic Print will help you differentiate between possible printhead errors and other
problems such as incorrect front-panel selection, driver or RIP configuration or mechanical problems. For
more information on solving print-quality problems, see Print quality on page 155.

Troubleshooting system error codes

System error codes on page 43 contains a list of system error codes and their respective descriptions and

recommended corrective actions. Try only one recommended action at a time and check whether 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.

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.

●

The service configuration print.

●

The current configuration sheet.

●

Which software application the customer is using (name, version, etc.).

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 Service tests and utilities on page 91.

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 calibrations on page 131.

NOTE: Remember that certain calibrations are required even if an assembly has been disassembled only to

gain access to another assembly or component.

The printer does not power on

To resolve printer power-up problems, do the following:

4 Chapter 1 Troubleshooting ENWW

1. Check that the power cord is connected correctly to the printer and to the power socket.

2. Check that the power switch at the rear of the printer is in the on position.

3. Check that the front-panel cable is correctly connected to the Electronics Module. Also make sure that

the front-panel cable is not damaged.

4. Check to see if any of the LEDs on the power switch are on. If any of the LEDs are on, then see How to

read the power switch LEDs on page 18 for more information.

ENWW The printer does not power on 5

Incorrect Ink Cartridge troubleshooting

When the customer inserts an Ink Cartridge that is not compatible with the region for the printer the
following message is displayed:

If this is the first time that an incorrect ink cartridge of that color is inserted in the printer, the customer can
press OK to continue using that cartridge and the printer will use and finish the ink cartridge.

After the first time, the printer will reject all ink cartridges of the same color that do not match the selected
region of the customer (please refer to the Ink Cartridge family compatibility chart below).

In case of ink cartridge incompatibility do the following:

6 Chapter 1 Troubleshooting ENWW

1. Check the product family of the ink cartridge used. Make sure that product family matches the region

defined for the customer’s country (see the country list below).

2. Check the printer region set in the printer, and/or supplies, match the customer country

If the country is not properly set, correct the country as described in xxxx

With both the product family and printer region correctly set (see the compatibility chart above),
supplies will work.

As rejected ink cartridges will still work on printers that are compatible, ink cartridges are not replaced
by HP under warranty because of this type of mismatch.

Check the region and supplies compatibility

View compatible ink cartridge information by selecting the icon.

View the region setting in the Printer Information menu by clicking on the icon:

This information is also available in the Current Printer Configuration tab in the Embedded Web Server:

Change the printer region

The procedure to change the printer region is described in the User’s Guide. To change the printer region:

1.

Select the icon.

ENWW Incorrect Ink Cartridge troubleshooting 7

2. Open the Ink menu.

3. Scroll to Replace Ink Cartridges.

4. Press the Cancel key and the Down key at the same time, and hold them down for at least two seconds.

The Printer will display the following message:

5. After selecting the Front Panel language, select the region for the ink cartridges.

6. The printer will show the selected region.

7. Press the Down key to view the countries in the region selected.

The complete list of countries can be found in the Appendix: Country lists on page 459 at the end of this
Service Manual.

8 Chapter 1 Troubleshooting ENWW

8. On confirmation, the Printer will display the the supplies that are compatible with the region selected.

Press the Back key to select a different region.

9. At the end of the process the printer will reboot.

After the region has been reset once, the Printer region cannot be changed again by the user. If the user
tries to change the region again, the Printer will display the following message with a Code.

Call agents need to raise a case with GBU through the GCC with the following information:

●

Code ID for Region Change of the printer

●

Printer Serial Number

●

Region to be set for this particular printer

●

Customer Name

●

Customer Address

10. GBU will provide an Ink Regional Code.

With the Ink Regional Code customers can proceed with region change.

The printer will show a screen to enter Ink Regional Code then:

Customers can select the character by pressing Upwith and Downarrows and selecting Ok. When the
Code is entered correctly, the customer selects the Return symbol and pressesOk

This will set the printer Region as requested by the Customer to the GBU.

If the code is not correct, the printer will display the following message:

The printer continuously rejects printheads

To resolve printhead rejection problems, do the following:

1. Clean the flex contacts on the Printhead and in the Carriage Assembly using the Carriage Interconnect

Wiper (see Carriage Interconnect Wiper on page 89) and try again.

2. If all the Printheads are rejected (for each Printhead, the status message on the Front Panel does not

show 'OK') then perform the Carriage Assembly Test Carriage Assembly test on page 98.

ENWW The printer continuously rejects printheads 9

A new maintenance cartridge is incorrectly detected as ‘used’

This can occur if the printer has detected the previous Maintenance Cartridge was nearly full, and when a new
Maintenance Cartridge is installed the front panel displays an error that the cartridge is ‘used’. To resolve the
problem, manually reset the counter of the Maintenance Cartridge Reset Life Counters on page 116.

Cover sensors are not working

To resolve cover sensor problems, do the following:

1. Check whether the sensor cable is damaged or not connected correctly.

2. Replace the faulty sensor.

The Line Sensor has problems detecting paper

To resolve Line Sensor paper detection problems, do the following:

1. Check the type of paper that is being used: the Line sensor may have problems detecting transparent

paper or some types of Non-HP paper. Try loading white HP paper into the printer and check whether
the Line Sensor detects it.

2. Excessive ink deposits on the Platen surface can fool the sensor by reflecting the light. Clean the Print

Platen.

3. Clean the Encoder Strip See Clean the Encoder Strip on page 450.

4. The Line Sensor is not calibrated correctly. Perform the Line Sensor Calibration See Line Sensor

calibration on page 139.

5. The Line Sensor is damaged or faulty. Replace the Line Sensor See Line Sensor Assembly

on page 379.

Troubleshooting paper jams and printhead crashes

NOTE: If you were using HP Coated Paper when the problem occurred, see also Printhead crashes/smears

on high-density prints using coated paper on page 13.

Paper jams and printhead crashes are grouped together because in many cases a paper jam causes the paper
to lift up into the Carriage path and cause a printhead crash, which means that many paper jams are reported
as printhead crashes.

10 Chapter 1 Troubleshooting ENWW

Question Answer

Did the paper jam occur when loading paper? If paper jams have occurred previously, some pieces of paper may

still be stuck in the paper path. Clear the paper path.

NOTE: Customers often store used rolls without protecting

them from office environmental conditions; when exposed to
high humidity, the paper edges tend to curl. This curling can
cause paper jams when paper is loaded by feeding paper in
without lifting the Media Lever. In these conditions, to avoid
paper jams, the recommendation is to load paper by lifting the
Media Lever and aligning the paper manually, following the
instructions on the front panel.

Is the customer using non-HP paper? The use of non-HP paper can easily be the cause of paper jams

and printhead crashes—especially printhead crashes, because HP
paper is specially formulated to avoid cockle, one of the primary
causes of head crashes. If the paper is not HP-approved, advise
the customer to use HP paper and check to see if the problem is
now solved.

TIP: When clearing a paper jam, sometimes paper is stuck in the paper path. To clear this, you must lift the

Media Lever and insert thicker paper into the paper path to push out the paper that is still stuck there.

Troubleshooting paper, scan axis and Rewinder Motor shutdown

If a shutdown occurs, you will get the message “Switch Power Off” followed by one of these messages:

●

Check Maintenance Cartridge Path

●

Check Paper Path

●

Check Printhead Path

NOTE: A shutdown in each path will require different steps to resolve the problem as explained below. In

each case, make sure that you power off the printer before trying to resolve the problem.

Also check that the Rewinder Motor moves easily (without friction) with the printer turned off.

Maintenance cartridge path

Open the right door of the printer and check for any visible obstacles restricting the movement of the Service
Station. Manually move the Service Station, checking for smooth and free movement.

Paper path

To resolve paper path problems, do the following:

1. Open the Window and check for any visible obstacles restricting the movement of the Drive Roller. Make

sure that the mylar is not damaged. If there is a wrinkled mass of paper inside the paper path, lift the
Pinch wheels (using the Paper Load Handles) and clear the obstruction.

2. If this shutdown happens at the end of a Roll of Paper, it could be because the paper is stuck firmly to

the Roll. Lift the Pinch wheels (using the Paper Load Handles) and pull the paper clear.

ENWW Troubleshooting paper, scan axis and Rewinder Motor shutdown 11

3. Replace the spindle if broken.

4. Perform the Paper Drive Test to obtain further information on the problem Paper Drive test

on page 94.

Printhead path

When a shutdown occurs in the Printhead path, you will get the message “Switch Power Off / Check Printhead
Path (*). The (*) will be a number, which will give an indication on where the failure occurred.

PWM shutdown

To resolve a PWM shutdown, do the following:

1. Clean Slider Rods and Apply Oil along the complete axis of the Slider Rods. After applying the Oil,

perform the Scan-Axis Test See Scan Axis test on page 94 and check that the values are within the
given limits.

2. Clean the Encoder Strip See Clean the Encoder Strip on page 450.

3. Perform the Scan-Axis Test to obtain further information on the problem Scan Axis test

on page 94.

Velocity shutdown

To resolve a velocity shutdown, do the following:

1. Open the Window and check for any visible obstacles restricting the movement of the Carriage

Assembly. Try and move the Carriage Assembly manually, checking for smooth and free movement.

2. Check that the Encoder Strip is clean. If necessary, clean Encoder Strip using a damp cloth.

Energy shutdown

To resolve an energy shutdown, do the following:

1. Clean Slider Rods and Apply Oil along the complete axis of the Slide Rods. After applying the Oil,

perform the Scan-Axis Test See Scan Axis test on page 94 and check that the values are within the
given limits.

2. Clean the Encoder Strip See Clean the Encoder Strip on page 450.

3. Perform the Scan-Axis Test to obtain further information on the problem Scan Axis test

on page 94.

Vacuum suction much lower at high altitudes

At altitudes above 3,000 meters, the vacuum force holding down the paper will be lower, therefore the paper
will not be held in place properly causing:

●

Ink Smearing on the Paper.

●

Printhead crashes against the Paper.

●

Roll Paper loading problems (low probability).

12 Chapter 1 Troubleshooting ENWW

Banding at variable extreme environmental conditions

NOTE: This problem is only applicable if the OMAS is disabled.

Since the Accuracy Calibration has been done at normal environmental conditions, 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:

Perform the Accuracy Calibration in the new environmental conditions (see

Using your printer).

Printhead crashes/smears on high-density prints using coated paper

High-density prints can cause cockle mainly on HP Coated Paper. This causes two main problems:

. Cockling in the borders - Because the printer places too much ink on the Coated Paper, the borders of

1

the print become raised, causing the Printhead to crash against the paper. To solve the problem, add a
15 mm white margin to the edges of the images.

. Cockling within the print - If the printer places too much ink within the print, the paper starts to ripple,

2

causing the Printhead to smear against the paper. To solve the problem, try the following:

●

Check in the Front Panel if

●

Avoid using HP Coated Paper for high-density prints. As a substitute, use HP Heavyweight Coated
Paper.

Ink Limiting is ON or OFF. If Ink Limiting is OFF, turn it ON.

Banding due to ink cartridge replacement while printing

Someone has removed an 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 printing restarted. This is because the wet ink interacts with the dried ink on
the paper causing the band to appear. To solve the problem, try the following:

●

Do not remove an Ink Cartridge while the printer is printing. Only replace/remove Ink Cartridges
between prints.

●

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.

●

Reprint the file (without removing the Ink Cartridge).

34-inch Rice Paper not supported

The roll width is 34 inches (non-standard), and the pinch wheels can't control the edge of the paper, causing
ink smears and printhead crashes.

Worm marks on HP Coated Paper with light area fills

Light bands (S-shaped) in the direction of the media axis when light area fills are printed, causing an
unacceptable print-quality defect.

ENWW Banding at variable extreme environmental conditions 13

●

Print the Service Configuration Print and check whether the ambient humidity is very low (below 30%).
Increasing humidity may help to reduce the severity of the problem.

NOTE: The paper is causing the problem and not the printer. Do not attempt to replace printer parts to

solve this problem.

Solving paper-handling problems

The front panel keeps indicating that paper Is misaligned or incorrectly positioned.

●

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.

NOTE: 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 paper may be loaded at an angle, causing the paper to be rejected.

●

The Line Sensor may be malfunctioning. See The Line Sensor has problems detecting paper on page 10.

Difficult to load paper: “Too much skew”

If you encounter a high failure rate when loading paper and the Front Panel reports “Too Much Skew” it is
likely that:

●

The encoder strip must be cleaned (this can be carried out by the customer using the User Maintenance
Kit).

●

The Line Sensor must be cleaned.

●

The Blue Line calibration must be performed. See Platen blue line calibration on page 148.

4. Check that the Take-Up Reel motor assembly is correctly connected to the rear of the printer.

How the Take-Up Reel works

When selecting the front panel's Paper menu, if there is no line Take-Up Reel installed, this indicates that
the Take-Up Reel has not been enabled at the front panel. This does not mean that the Take-Up Reel will not
work; it just means that, if there is a paper jam detected by the Take-Up Reel, there will be no warning
system error displayed on the front panel. The printer will not stop.

How to install the Take-Up Reel

From the Paper menu > Take-Up Reel > Enable Take-Up Reel. After this is done, you will notice the following
differences:

●

In case of Take-Up Reel Paper jam system error, a warning is reported on the front panel, and the
printer pauses.

●

The cutter is disabled between jobs.

●

When unloading the paper, the front panel will ask you to cut the paper manually.

How it works

When the bottom of the 'loop shaper' is low enough and it cuts the signal between the two sensors, the Take­Up Reel starts to move the motor until the signal between the two sensors is passing through again.

If, after a few seconds of turning the Take-Up Reel, the signal between two sensors is still cut, the Take-Up
Reel reports a 'Take-Up Reel paper jam' error:

How to read the power switch LEDs

In certain circumstances, the LEDs located on top of the power switch (located at the rear of the printer)
indicate the status of power supply to the printer.

1. When only the Amber LED is On:

●

The printer has been switched Off from the Front Panel (after having pressed the On/Off button).

●

The Power Supply Unit only delivers a 5 V “Standby”; power that is needed to restart the printer
after the Front Panel On/Off button is pressed (the Formatter will start the printer).

2. When the Blue LED is On: Deliver standard “ATX” power for the Electronics Module PCAs (+12V, +5V,

-5V, -12V, etc...). All the functions of the Electronics Module are fully operational (EWS, etc...).

3. When the Green LED is On: Deliver “analog” 24V and 36V to enable printing.

If you turn on the printer at the front panel, and the Blue LED does not come on, there is a problem. Turn off
the printer using the switch at the rear, then turn it on again using the same switch. If the Blue LED still does
not come on, replace the Power Supply Unit.

If the Blue LED comes on this time, you will probably see an error reported on the front panel as the printer
starts up. If no error is reported, but you continue to have problems when turning on the printer from the
front panel, see How to read the Formatter LEDs on page 19.

18 Chapter 1 Troubleshooting ENWW

How to read the Formatter LEDs

The LEDs located on the Formatter can help to troubleshoot the printer. The LEDs can either be on or off;
different combinations can indicate different problems.

The following image shows the three Formatter LEDs, which are numbered from the top down: number I at
the top, number II in the middle, number III at the bottom.

Use the following table to interpret the LEDs and find the source of the problem. Remember that you should
read these LEDs when you push the

Power button.

Some combinations may require you to replace two or more components. In this case, always replace one
component at a time. Test the printer to see if the problem has disappeared (check the LEDs again). If the
same LED sequence continues, replace the next component indicated in the table.

If the front panel turns on and then stops

If the power-up process stops while the front panel is displaying a number, respond as follows.

1. If the printer's Power-Up process stops when the front panel is displaying the number 17, this indicates

that there is a problem with the file system on the printer's Hard Disk Drive, so the printer is checking
the whole file system and making any necessary corrections. This problem can arise when there has
been a power cut while the printer was switched On, or if there is a physical problem with the Hard Disk
Drive.

Checking the whole file system normally takes about half an hour (but could take much longer). There is
nothing that can be done to speed up the file checking process. If you turn Off the printer during the
checking process, the file system check will restart whenever you turn it On again

If you experience this problem repeatedly when there has been no power cut, then this could mean that
the Hard Disk Drive is faulty. In this case, replace the Hard Disk Drive See Hard Disk Drive (HDD)

on page 364.

2. If the printer's start-up process stops when the front panel is displaying any other number between 1

and 30, then try the following:

●

Turn the power off at the rear of the printer and disconnect the power cord. Reconnect the power
cord and turn on the printer.

●

If the printer continues to stop during the power-up process, replace the Hard Disk Drive See

Hard Disk Drive (HDD) on page 364.

When the main window is open and the printer is printing (safety compliance)

We describe the details of the behavior of the printer when the window is opened while the carriage is
moving.

If the main window is opened while the printer is doing something, be it a swath of a print job or a system
task, the printer will:

ENWW When the main window is open and the printer is printing (safety compliance) 29

1. Before the carriage stops, it will finish whatever it was doing when the window was opened. It will not

finish an image it was printing, but it will finish the current swath, so as to avoid any impact on image
quality. If it was performing a system task it will finish it before stopping.

2. If the carriage finishes on the left side of the printer, the carriage will always slowly move to the right

side of the printer.

3. The printheads will be placed in their 'capping' positions.

Here are some different scenarios of what happens when the window is opened:

●

If the printer is printing an image when the window is opened: The carriage will not stop immediately,
the printer will finish the swath and then stop. If the cover is then closed, the printer will start to print
from the position it was stopped.

●

If the printer is cutting the media: The carriage finishes the cutting procedure.

●

If the printer is checking the SKEW while loading the media: During the skew check, the printer does
small movements of the carriage on the right side of the printer, and also moves the media when
needed. This procedure checks that the edge of the media is moving laterally or not. If the window is
opened while the printer is checking the media SKEW, the printer will complete the skew procedure (and
it will continue well after the window has been opened). This is the only case when the printer will not
stop the carriage at the end of a lateral movement (as a swath).

The safety system in place is designed to detect an object in the path of the carriage as it moves across the
printer, any object encountered will cause the system to shut down the driver motor in the carriage. This
method of ensuring safety is considered sufficient by the regulatory agencies that inspect and assess the
product prior to its placement in the market. The window and its switch are considered a ‘supplementary’
safety feature, and as such the behavior of the switch has been adjusted as a trade off between the level of
safety provided and the printer’s functionality.

How to troubleshoot the 79:04 system error

●

Introduction

●

Possible causes

●

Troubleshooting based on symptoms

Introduction

The System error 79:04 is a generic firmware error (equivalent to a blue screen in Windows). It’s the System
Error that the printer will display when an unknown exception occurs that cannot be pointed to by any
specific subsystem of the printer.

Since this is a generic error, there can be multiple causes behind it. This document will cover the most
probable causes behind a system error 79:04 and will recommend the most efficient troubleshooting steps
to resolve customer issues.

One important point to mention is that, although 79:04 system errors can be caused by a hardware
malfunction, the vast majority of 79:04 system errors are pure software or firmware issues. In these cases
the issue can only be solved by determining the root cause and implementing a solution. The solution can
usually be applied by either correctly configuring a selection, updating the printer’s firmware/software that is
being used or by fixing an error in the code).

30 Chapter 1 Troubleshooting ENWW

Possible causes

Since the 79:04 system error is a generic error, the number of possible causes behind it is large. The majority
can be grouped, however, into the following groups:

Table 1-2 Job related SE79:04

Job related SE79:04

A specific print job that is not correctly formatted for the printer or that is not correctly processed by it can trigger a 79:04
system error.

The incorrect format or processing can come from two sources:

• Incorrect commands in the job itself. For example, a PS job with some commands that do not have the correct PS format.

• Issues applying to the settings in the job

Cause Solution

79:04 caused by a print job always have the same symptoms:

●

1. The job is received by the printer and starts to
process.

2. In the middle of the processing, the printer stops
and displays 79:04.

3. The printer will display the 79:04 system error again
immediately after restart. This is due to the fact
that the printer will try to reprint the job, which is
pending in the queue, after restart.

4. After the second restart, the printer will start up
normally

5. If the same job is sent again, it will always produce a
79:04 system error

These types of 79:04 system errors are normally caused by jobs
that have been generated by 3rd party applications (RIPs, 3rd party
drivers, files exported by an application to PS, PDF, HP-GL/2, RTL,
… or any other format supported by the printer). Jobs generated
by HP drivers will not normally generate 79:04 system errors,
since the output that our drivers generate is very controlled and
has been designed taking into consideration the characteristics of
our printer’s language interpreters.

There is an exception to this general rule: there are certain
applications that can generate their own PS code (Adobe
PhotoShop, Adobe Illustrator, Adobe Acrobat, Corel Draw,
Freehand, QuarkXpress, …). When used with a PS driver, these
applications generate the output PS themselves, instead of using
the driver’s rendering capabilities. This is known as PostScript
pass-through. So, when using an HP PostScript driver together
with an application that has PS passthrough capabilities, the PS
code that comes into the printer has not been rendered by the HP
driver, and, should the source file contain any PS commands that
are not correctly processed by the printer, a 79:04 system error
could occur even though an HP driver is being used.

When a job consistently generates a 79:04 system error, it is
either because of a issue in the printer’s firmware or because of a
defect in the job itself (when it has been generated by 3rd party
SW). In order to identify the cause and find out a solution, these
issues should always be immediately escalated to the GBU
through the GCC.

Also, there are a set of workarounds and short term solutions
that can be tested in order to get the customer up and running in
the shortest possible time:

1. Send the job using a variety of different settings. Many

times, the issue is caused by a combination of the job
contents combined with some specific setting(s).

2. If the customer is sending the file directly to the printer, try

using the HP driver instead.

3. If the issue is occurring when printing through the HP

PostScript driver from an application with PS passthrough,
try changing the options in the application so that it prints
PS as raster (the option is typically located in the 'Advanced'
options of the application’s printing dialog).

ENWW How to troubleshoot the 79:04 system error 31

Table 1-3 Data related SE79:04

Data related SE79:04

HP Designjet printers have Hard Disks and non-volatile memories that contain data bases and files that can be modified with user
data. Some examples include:

• The printer’s queue

• The hard drive partitions that contain user jobs

• The data base that stores the printer settings

• The data base that stores accounting information

Some of this data is accessed by the printer at start up, and some others are accessed as needed.

If any of this fields contains corrupt data or data with characters or values that cannot be correctly processed by the printer, a
79:04 system error may occur.

Cause Solution

There are two different types of symptoms for data related 79:04
system errors:

●

1. When the corrupt data is accessed during start up:

a. The printer will display a 79:04 during the start

up process

b. Switching the printer off and on again will not

solve the issue. The printer will continue
displaying the 79:04 system error until the
corrupt data has been cleared through a
service procedure.

2. When the corrupt data is accessed during normal
printer operation:

a. The printer will start up normally

b. When the data is accessed (for example while

printing, while navigating the queue or when
changing some settings), the printer displays a
79:04 system error

c. The printer can restart normally

d. When the data is accessed again (typically,

under the same conditions as in step “b”), the
79:04 system error is displayed again.

Many times, data related 79:04 errors are resolved by means of
hardware intervention. Since data is stored in physical
components (RAM, EEROM and Hard Disk), replacing these
components with new ones which are empty usually solves the
problem. However, there are quicker and more effective solutions
to these types of errors:

1. Clear all information that has been introduced by the user

using the standard tools available in the printer:

a. Delete all jobs from the queue (from the Front Panel or

the EWS)

b. Reset to factory defaults to clear the user’s

configurations and calibrations

c. Delete any non-standard paper preset in the printer

(both the ones that have been created by the user and
the ones that have been installed as OMES profiles
through the EWS or the HP Utility)

2. If step 1 did not resolve the issue, you can use Service Tools

to clear additional information that could be causing the
issue:

a. Start the printer in Diagnostics Boot Mode

b. Perform an EEROM reset

3. If step 2 did not resolve the issue, it is possible to

completely clear the information on the Hard Disk and the
different EEROMs, leaving them in an equivalent state to a
new part:

a. Access the Service Utilities Menu

b. In the Secure Disk Wipe menu, set the Sanitize level to

“Unsecure mode”

c. Execute the Disk Wipe. This takes 45-75 minutes and it

will completely clear all partitions in the Hard Disk
which contain user data, including the partition where
the Operating System is installed. After the disk wipe
has completed, a backup firmware version will

automatically be installed from a backup partition to
allow the unit to start up. This firmware version is very
old.

d. The firmware in the printer should be updated to the

latest official version as soon as the printer has
restarted.

After step “c”, any 79:04 which is caused by corrupt data in
the printer will be solved.

NOTE: It is possible that the corrupt data came to be in the

printer as a consequence of some activity in the customer’s
workflow. In this case, it is possible that the issue will
happen again. In these cases, it is very important to
understand the sequence of events in the customer’s
workflow that led to the error occurring. Once the error can
be traced in the customer’s workflow, escalate the issue to
the GBU (through the GCC). This is done to implement any
changes in the printer’s firmware that can prevent these
issues occurring again.

ENWW How to troubleshoot the 79:04 system error 33

Table 1-4 Network related SE79:04

Network related SE79:04

Most HP Designjet printers have built-in networking capabilities. Network settings can be set manually, but in the majority of
cases, they are obtained automatically from the printer. These settings include many different fields, such as IP address and
subnet mask, available gateways, host and domain names, etc.

In some cases, there can be issues in the firmware that can cause a certain value in one of these fields to be interpreted
incorrectly, and this can lead to a 79:04 system error.

Cause Solution

There is no single set of symptoms that can absolutely pinpoint a
network related 79:04 system error. However, the following
guidelines can be applied:

●

It can happen at start up or when accessing the Network
Configuration section of the FP

●

In both cases, repeating the action with the LAN cable
disconnected does not cause the 79:04 to occur

In the majority of cases, these issues will be due to an issue in the
printer’s firmware. As soon as the conditions where the issue
happens can be understood, it should be escalated to the GBU
through the GCC.

At the same time, the following short term solutions and
workarounds can help the customer to get up and running in the
shortest possible time:

1. Disconnect the network cable to be able to boot the printer

and change network settings

2. In the Network configuration menu in the Front Panel,

disable any protocols that you are not using, including IPv6,
SNMP and WebServices.

3. If step “2” does not work, try setting a manual configuration

of the device:

a. Enter the correct subnet mask and an IP in the valid

range

b. In the GateWay field, set the same value as in the IP

address field

c. Do not set a host name or a domain name

4. If step “3” does not work and the customer is using the

network card which is part of the printer, try using an
accessory Jetdirect card instead.

34 Chapter 1 Troubleshooting ENWW

Table 1-5 User Interaction related SE79:04

User Interaction related SE79:04

In some cases the printer may not react as expected when a certain set of conditions coincide. In these cases, if the printer
doesn’t know how to react, it may simple display a 79:04 system error and force a restart. Some examples (not real) that can help
to illustrate this:

• An error occurs when a job is cancelled when it is at the “Finishing print” state and when the queue is disabled

• An error occurs if the Window is opened while the printer is checking the printheads

These errors will most likely only happen in very specific corner cases that have not been identified during the development or
the qualification of the printer, so normally, they do not severely impact the customer, as they do not affect their regular
working flows.

Cause Solution

The symptoms here are as numerous as the number of possible
interactions between the user and the printer. In any case, it’s
possible to identify the steps that caused the error to occur and
avoid them as the steps will always be the same with no variance.

Important: An major element in determining the error is what the
state the printer was in at the time the error was displayed.
Actions the user has made when the printer is drying for example
can produce an error, whereas the same action when the printer
is doing something else (or is idle) may not produce any errors.

The recommended action plan in these cases is to identify the
previous steps that caused the error and:

1. Escalate the issue to the GBU through the GCC in order to

have it corrected in the firmware.

2. Recommend to the customer that they try to avoid the same

steps to prevent the issue

3. If the conditions that cause the error are in the customer’s

regular workflow, try to identify a different way of achieving
the same result out of the printer.

ENWW How to troubleshoot the 79:04 system error 35

Table 1-6 Random SE79:04

Random SE79:04: Concurrence issues and memory leaks

Some 79:04 errors can happen randomly when the printer is being heavily used. However, it’s impossible to find a single set of
conditions that reproduce the problem. It just happens from time to time, without a defined pattern.

These random 79:04 can have two different types of root causes:

• Memory leaks: Before a program is executed, it allocates the memory it will need. After the execution is complete, the allocated
memory is freed to be used by other programs. If the allocation or the release of the memory are not properly programmed,
every time the program is executed some memory will be incorrectly labeled (either as used or as free). This is known as a
memory leak. When a program with a memory leak is executed a lot, the memory becomes progressively full (since it is not
properly freed). When the leak becomes too big, the printer is left ‘out of memory’ to execute new processes and a 79:04 is
triggered.

• Concurrence issues: There are certain resources that can be accessed by multiple programs or by multiple executions of the
same program (what is known as multiple threads). Access to these resources must be correctly controlled to prevent
unexpected behavior. Issues caused by an incorrect control of these resources are concurrence issues.

In the following you have a simple example: let’s imagine that there is a counter that controls the communication between the
Jetdirect card and the printer’s firmware. Whenever a new packet of information is sent by the Jetdirect card to the printer, the
counter increases. When the printer receives the packet and processes it correctly, the counter decreases. Another process
checks the counter from time to time to see its value and take conclusions from it. If the counter is near 0, it means that the
printer is processing correctly, and if it grows too big, it may mean that there is a bottleneck somewhere and maybe the Jetdirect
card throughput is decreased to control its speed to the printer. However, if the access to this counter is not properly controlled,
undesirable effects may happen: in a real environment, a Jetdirect card processes thousands of information packets per second,
so this counter is updated frequently, both by the Jetdirect and the printer. If at a certain point the Jetdirect and the printer try
to access the counter at the same time and the code is not prepare to handle this, it may happen that the Jetdirect cannot
increase the counter because the printer is writing to it, and what’s worse, that it does not realize this fact. If this happens a few
times each second, it may happen that the counter is decreasing faster than it’s increasing and that at a certain point it has a
negative value. And then, what will the process that is checking this counter do? Most likely, the process will not be prepared to
react to a negative value and will launch an exception that will trigger a 79:04 system error.

Cause Solution

This type of 79:04 always occurs in heavy load conditions, so the
symptoms will always be similar to this pattern:

●

A printer that is being heavily used (printing a project or in a
reprographics environment) produces 79:04 errors
randomly, forcing the user to restart.

●

After restarting, the printer can be used without any issues
for an extended period of time, but if the workload is
consistently high, a random error will occur again.

●

The error can never be associated with a specific file. The
file that was being printed when the error occurred the last
time can be printed without issues after restart. And a file
that has been printed without issues several times can
trigger the error in the future.

●

This error is very dependant of the workflow the customer
has. The most common user workflows have been
extensively tested both by HP and by our beta sites, so it is
highly unlikely to see random 79:04 issues in these cases.
These random issues tend to occur in very specific corner
cases, and cannot be reproduced unless the exact
conditions of the workflow are replicated. They normally
happen when sending files generated by external
applications (RIPs, 3rd party drivers, etc.).

Random 79:04 errors are, by far, the most complex ones to
diagnose and to fix. The only solutions available in these cases
are:

1. Identify the root cause (either in the files or in the firmware)

and fix it in the code, which requires the intervention of the
GBU

2. Test any options available to modify the customer’s

workflow and see if any combination of them solves the
issue

In both cases, a profound understanding of the customer’s
workflow is necessary. In particular, the information that is
needed is:

●

Printer front panel settings

●

Application that is being used; RIP or driver that is being
used

●

Application/RIP/Driver settings

●

Type of output files this application, RIP or driver is
generating

●

Some sample files that are representative of what the
customer is using

●

Operating System

●

Method of connection to the printer

A description of the normal flow when the issue occurs and
the typical frequency of occurrence (i.e. once every hour
when sending several files non-stop, each of them with
multiple copies)

Table 1-7 Hardware related SE79:04

Hardware related SE79:04

Hardware is, by far, the least likely cause of a 79:04 system error. Replacing hardware components does not normally fix the
issue and increases the total turn around time in finding a workable solution.

In some cases, a failure in a component in the printer’s electronics may cause a 79:04 system error, since the printer’s electronics
are involved in the execution of the firmware and the processing of jobs. It needs to be noted, however, that hardware failures in
the electronics tend to produce specific system errors that point directly to the component that is failing.

Some HW causes that could be behind a 79:04 error are:

• Defective clusters in the Hard Disk drive. If these clusters are used to execute the firmware or to process a job, they may
produce a 79:04. It needs to be noted however, that most 79:04 errors that are resolved by an HDD replacement are in fact, data
related 79:04 that could have been solved more efficiently and quickly following the steps in Section 3.

• Defective memory segments. If the RAM memory has some defective segments, a 79:04 may occur when these segments are
used.

• Intermittent defects in the electronic components that are involved in the processing of a job: Carriage PCA, Trailing cable,
Formatter and Print Mech. This is a highly unlikely cause, since defects in these components will produce subsystem specific
errors.

Cause Solution

There’s no single set of symptoms behind hardware related 79:04
system errors. The most usual ones, however are:

●

79:04 during start up. Restarting the printer may or may not
solve the problem

●

79:04 while processing or printing a job. Restarting the
printer and printing the same job does not always produce
the error.

Troubleshooting based on symptoms

This section will describe which troubleshooting steps to perform for a 79:04 system error based on the
symptoms of the issue. Perform each step as it appears in the list and only move on to the next step once you
are sure the 79:04 error has not been cleared.

Front panel displays 79:04 at start-up

●

Restart the printer twice. If the system error has been caused by a job in an incorrect format, restarting
twice will clear the error (the first time after restart, the printer will attempt to print the job again, and

In the following procedure perform each step as it appears in the
list and only move on to the next step once you are sure the
79:04 error has not been cleared:

1. Restart the printer in Diagnostics Boot mode and execute

the service tests to validate the functionality of all the
electronics components

●

Execute the troubleshooting for “data related” system
errors, refer to page 3, Data related SE79:04

2. Replace the memory

3. Replace the HDD

4. Escalate the issue before replacing any additional parts.

ENWW How to troubleshoot the 79:04 system error 37

this will cause the error to re-appear). If restarting the printer twice solves the issue, then it is an issue
related to the job and you should refer to Possible causes on page 31

●

Update the printer’s firmware. Even if the currently installed firmware version is the latest one, reinstall
it. Since the printer cannot start normally, you will need to update the firmware while booting the
printer in Diagnostics Boot Mode. For this, a special file and a special update process will be needed. You
can find the specific information for the printer model you are troubleshooting on page 13, Appendix A .

●

Disconnect the network cable and restart the printer. If this solves the problem, then it is a network
related 79:04 and you should follow the guidelines for this type of 79:04, refer to Possible causes

on page 31.

1. Remove all cartridges, printheads and printhead cleaners (if available). Unload the media. Restart the

printer. If the printer can start normally, insert the consumables one by one until you isolate the one
that is causing the error. Do NOT insert any of the replaced consumables in another printer.

2. Restart the printer in Diagnostics Boot Mode and perform the “Electronics test”. If an electronic

component is identified as faulty, replace it.

●

Restart the printer in Diagnostics Boot Mode and Reset the EEROM. If the issue is solved by this,
this is a data related 79:04 system error and you should follow the guidelines, refer to Possible

causes on page 31.

3. If the unit has been used for some time and suddenly has started to show this behavior, replace the

Hard Disk Drive (it may be included with the Formatter in some models).

4. If the issue is new and the issue happens since the first boot, do NOT replace the HDD.

5. If none of the previous steps solved the issue, escalate the issue with the following information:

●

Unit information: S/N, P/N, accessories

●

Conditions where the problem occurs and conditions prior to the first occurrence of the problem

●

The results of the previous 8 steps

●

The System Error detailed information (this can be obtained by pressing CANCEL + Down)

●

The printer logs.

1. Restart the printer.

2. Update the printer’s firmware. Even if the currently installed firmware version is the latest one, reinstall

it.

3. Reset the printer to factory defaults.

4. In order to narrow the scope of the issue, try the following:

a. Disable the queue

b. Disable any unused network protocols

c. Disable SNMP and WebServices (if they are available in the printer)

38 Chapter 1 Troubleshooting ENWW

d. Disable “Sleep mode” from the Service Utilities menu

e. Delete any Paper Presets that you may have uploaded or created using the printer

Spectrophotometer.

5. Restart the printer in Diagnostics Boot Mode and perform the “Electronics test”. If an electronic

component is identified as faulty, replace it.

6. Restart the printer in Diagnostics Boot Mode and Reset the EEROM. If the issue is solved by this, this is a

data related 79:04 system error and you should follow the guidelines for this type error, refer to

Possible causes on page 31.

7. Format the Hard Disk drive. To do so, you will need to start the printer normally, enter the Service

Utilities menu and then the Secure Disk Erase option. Set the Erase method to “Fast Erase” and then
perform the disk erase process. This will take 45-75 minutes and will erase all user information from
the disk, resolving any issue caused by corrupt data. After the erase process, a firmware update will be
required. If this solves the issue, this is a data related 79:04 system error and you should follow the
guidelines for this type of 79:04, refer to Possible causes on page 31.

8. Try to identify the combination of settings or actions that led to the system error and try to reach the

same result with a different combination. Escalate the issue to fix the original problem.

9. If none of the previous steps could solve the issue, escalate it with the following information:

●

Unit information: S/N, P/N, accessories

●

Conditions where the problem occurs and conditions prior to the first occurrence of the problem

●

The result of the previous 8 steps

●

The printer information pages (either printed and faxed or obtained through the Embedded Web
Server)

●

A. While printing a single job

●

B. Random 79:04 during continuous printing

A. While printing a single job

The error happens after a single job is sent. It’s easy to identify which job that has produced the error, since
every time that this same job is sent, the error is replicated.

1. Restart the printer twice (after the first restart, the printer will show the 79:04 system error again, since

the printer will attempt to reprint the last job in the queue, which is the one that caused the issue)

2. If you are using an HP driver, update the driver to the latest version

3. Update the printer’s firmware. Even if the currently installed firmware version is the latest one, reinstall

it. Send the job using different print settings. The following ones can be helpful:

a. Try sending the job without selecting a paper preset in the driver

b. Try changing the Image Quality settings

ENWW How to troubleshoot the 79:04 system error 39

c. If you are using the HP-GL/2 driver, try the option “Send job as bitmap”

d. If you are using the PS driver, try using the HP-GL/2 driver instead

e. If you are using the PS driver from an Adobe application (or any other application that can handle

PS), try changing the application’s print settings so that the PS is generated as Raster.

4. Try the following Front Panel settings:

a. Change the Print Language option in the Front Panel from “Automatic” (which is the default

setting) to the language that is being printed (PS, HP-GL/2, …)

b. Queue = OFF

c. Start Printing = After processing

d. For PS SKUs, try changing the encoding setting (“Automatic” by default) to Binary or ASCII

5.

If you are using a 3rd party application that does not print through the HP driver, try modifying the
printing workflow by:

. Using an HP driver

a

. Changing the settings in the application’s printing dialog

b

. If you are using an accessory Jetdirect card, try using the internal network connector or USB (if

B. Random 79:04 during continuous printing

The error does not happen with a single job. It happens randomly during continuous printing, normally while
the printer is managing a heavy load (printing a project or in a reprographics environment).

This type of error is caused either by memory leaks or by concurrence issues in the printer’s firmware. They
normally happen in unusual environments where these memory leaks or concurrence issues that have not
been detected during qualification have occurred. These issues cause the printer to crash at a completely
random moment during printing, and are not associated to a specific job.

Because of this, troubleshooting these issues is normally quite complex.

1. Restart the printer twice (after the first restart, the printer will show the 79:04 system error again, since

the printer will attempt to reprint the last job in the queue. If the issue continues occurring randomly,
continue troubleshooting

2. If you are using an HP driver, update the driver to the latest version

3. Update the printer’s firmware. Even if the currently installed firmware version is the latest one, reinstall

it.

4. Try the following changes in the workflow:

a. Change the Print Language option in the Front Panel from “Automatic” (which is the default

setting) to the language that is being printed (PS, HP-GL/2, …)

b. Queue = OFF

c. Start Printing = After processing

d. For PS SKUs, try changing the encoding setting (“Automatic” by default) to Binary or ASCII

e. If you are using the HP-GL/2 driver, try sending the job as a bitmap

5.

If you are using a 3rd party application that does not print through the HP driver, try modifying the
printing workflow by:

. Using an HP driver

What to do if the front panel is blank

No system error message can be displayed when the front panel is blank. In these cases the front panel has
not necessarily failed—any other electronic component can be the root cause. The Power Switch and
Formatter LEDs can help you to troubleshoot a problem in this situation; see How to read the power switch

LEDs on page 18 and How to read the Formatter LEDs on page 19.

System error codes

System error codes are hexadecimal 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. Try one recommended action at a time and check whether 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 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 Internal Error Code and

the firmware version. Without this information, HP Support Personnel cannot help you. To view the Internal
Error Code, hold the DOWN key and press the CANCEL key at the same when the System Error Code is

What are ink supplies?

Three different components are classed as ink supplies: the Ink Cartridges, the Printheads and the
Maintenance Cartridge.

Ink Cartridges

The HP Designjet Z6200 and Z6800 printer's eight Ink Cartridges provide matte black, photo black, light gray,
red, magenta, light magenta, yellow and light cyan ink to the Printheads. The HP Designjet Z6600 printers six
Ink Cartridges provide matte black, photo black, light gray, red, magenta, light magenta, yellow and light
cyan.

The Introductory Ink Cartridges supplied with the printer have 160 ml of ink, which is an average lifespan of
one month beyond the ink used to set up and install the printer. The ‘Host’ Ink Cartridges which are
purchased to replace the Introductory Ink Cartridges hold approximately 775 ml.

The Ink Cartridges for the HP Designjet Z6200/Z6600/Z6800 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.

The front panel displays the status of the Ink Cartridge. Using the front panel, detailed information can be
checked on the Ink Cartridges.

The following tables list the Ink Cartridges for the HP Designjet Z6200/Z6600/Z6800 printer series.

Printheads

The printheads are connected to the ink cartridges. They use jet action to put ink on the paper. Each
printhead has two ink cartridge connection points and two jet nozzles, which means that each printhead
accommodates two ink cartridges. For example, the following printhead image indicates a printhead that
draws and jets ink from the magenta and yellow cartridges.

80 Chapter 3 Ink supplies ENWW

The Printheads are extremely durable and do not need to be replaced every time an Ink Cartridge is replaced.
They are independent of the Ink Cartridges and will continue giving excellent image quality results even if the
Ink Cartridges are low on ink.

If you notice a decline in print quality such as lines or dots missing from text/graphics, go to Initial print-

quality troubleshooting actions on page 156.

The following table lists the Printheads for the HP Designjet Z6200/Z6600/Z6800 printer series.

Maintenance Cartridge

Use the Maintenance Cartridge to clean and maintain the Printheads, ensure the best possible print quality,
and seal the Printheads when they are not in use to prevent them from drying out.

The Maintenance Cartridge for the HP Designjet Z6200/Z6600/Z6800 printer series is the HP 771
Maintenance Cartridge, part number CH644A.

General information about the ink supplies

For optimum results from the printer and modular ink delivery system always follow these guidelines when
handling the ink supplies:

ENWW General information about the ink supplies 81

●

Allow the printer and the Maintenance Cartridge to automatically clean the Printheads.

●

Follow the instructions on the front panel of the printer during installation.

●

Avoid unnecessary removal of the Ink Cartridges and Printheads.

●

When turning off the printer always use the power Off button on the front panel. The Printheads are
then stored correctly which prevents them from drying out.

●

The Ink Cartridges should never be removed while the printer is printing. They should only be removed
when the printer is ready for you to replace them. The front panel will guide you through the removal
and installation procedure.

NOTE: The expiration date for the Ink Cartridges, Printheads and Maintenance Cartridge is printed on the

packaging.

NOTE: When reporting a 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.

General precautions when handling ink supplies

CAUTION: 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.

●

The Maintenance Cartridge should always be handled and stored upright to avoid a potential spillage of
ink.

●

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.

Priming the ink system

When the customer first receives the printer, it is supplied with a set of four Setup Printheads pre-installed in
the Carriage Assembly. These Setup Printheads are used for the priming of the tubes in the modular ink
delivery system. The customer must not remove the Setup Printheads from the Carriage without following
the procedures in the Assembly Instructions.

When the printer is powered on for the first time, the printer will automatically perform the priming process.
Without the priming process, the customer will not be able to use the printer.

Why does the printer require priming:

82 Chapter 3 Ink supplies ENWW

●

The Tubes System is empty when the customer receives the printer.

●

The Tubes System has to be pressurized and filled with ink, ejecting any air bubbles.

CAUTION: If the Printing Printheads are installed in the carriage during the priming process, they will

be rejected and the front panel will show a warning message.

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.

Printhead life is anticipated to be 1200 ml or twelve months in the printer, whichever occurs first, provided
that the printhead is used under normal operating conditions (using HP Ink Cartridges only) and its “install
before date” has not lapsed. However results vary depending on the print-quality setting being used.

Summary of 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.

Problems reseating the printhead

If you have inserted the printhead into the printhead carriage assembly and the printer does not “BEEP” try
the following steps.

CAUTION: Check that during the priming process, the Setup Printheads are installed in the Carriage. If the

printing Printheads are installed in the carriage during the priming process, they will be rejected and the front
panel will show a warning message.

●

Check that the protective tape has been removed from the printhead.

●

Insert the Printhead into the Carriage Assembly but this time correctly close the cover using the latch.

●

Clean the electrical contacts on both the printheads and the printhead Carriage Assembly using the
carriage interconnect wiper ⇒ Carriage Interconnect Wiper on page 89.

●

Replace the Printhead with a new one.

You cannot insert the Ink Cartridge into the printer

1. Ensure that you have the correct HP no. 771/773 Ink Cartridge.

2. Ensure that the Ink Cartridge is the correct color for that slot.

3. Ensure that the Ink Cartridge is the correct orientation, with the color coded label at the top.

CAUTION: Never clean inside the Ink Cartridge slots as this can cause damage to the printer.

Troubleshooting Printhead error codes

The Printhead Error Codes can be found on the Service Information Print (Setup Menu/Information Menu/
Internal Prints/Print Service Information/Current Information). The actual error code is a decimal number and
it has to be converted to a binary number before it can be used.

In order to convert the decimal error code to a binary error code, you can use a calculator. For example, if you
had the error code 4099, you would enter 4099 as a decimal number and then select the binary option which
would give you a binary number of 1000000000011.

The following table explains the meaning of the different bits (0 or 1). When the value of the error code is
reported as 0, it means that the Printhead is working correctly:

The binary number needs to be read from right to left so that the 1st bit corresponds to the right one of the
binary number. For example, the error code 4099 is converted to binary number 10000000000011. So using
the table above, the error code means “FAILS_LOGICAL_V”, “FAILS_CONTINUITY” and “MISMATCH”.

88 Chapter 3 Ink supplies ENWW

Carriage Interconnect Wiper

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.

The Carriage Interconnect Wiper is available as an accessory in a separate package. The package also
contains replacement sponges and an instruction sheet. This tool should be used for cleaning the electrical
interconnects of both the Carriage Assembly and the Printhead.

If the front panel displays the message Reseat or Replace next to the offending printhead, try cleaning the
flex circuits of the Carriage and the Printheads.

CAUTION: Do not touch, wipe or attempt to clean the printhead nozzles. This can damage the printhead and

reduce print quality.

Introduction

This chapter explains how to use the built-in Service Tests and Service Utilities and what to do if any of the
Service Tests fail.

NOTE: If possible, always perform a Service Test on the component that you are about to replace, just to

make sure that it is the component that has failed. If the test on that component passes, there is no need to
replace it.

Diagnostics—self test

Whenever the printer is switched ON, it automatically performs a series of internal self tests and mechanical
initialization sequences. If any of the parts fail, a system error will appear and you should consult “System
Error Codes” on page 43.

Phone support

In certain circumstances, a Call Agent can try and troubleshoot the printer by requesting the Customer to
perform a Service Test via the phone. Using this process, it can be determined whether the printer requires
any on-site maintenance.

Remember that the key combination for the customer to enter the Service Tests and Utilities is different from
the one that the engineer will use.
