Paper loading

Paper-advance calibration

Printhead alignment

●

Use of multiple rolls

ENWW 1

Paper loading

Rolls with 3-inch cores cause fewer ink smears and paper jams, and the finished prints stack better, in the bin
or the HP stacker.

To avoid selecting the wrong paper name when loading, we recommend hiding paper types that you never
use, which can be done from the HP Utility.

Paper-advance calibration

The printer will automatically start paper-advance calibration in the following situations.

●

A new type of plain or coated paper is loaded for the first time. Each type is calibrated separately: for
instance, there is one calibration for plain paper and another for HP Universal Inkjet Paper.

●

A new matte-black printhead is installed.

●

The firmware is updated.

Calibration adjusts the paper advance to reduce banding and line continuity issues for each paper type
(including all different roll sizes). It is important to use a different front-panel name for each paper type. For
example, if a third-party plain paper A is loaded as “plain” in the front panel, and a third-party paper B is also
loaded as “plain”, the printer may not be optimized for paper B. We recommend in this case using a different
name for B, for instance “HP Universal Inkjet Paper”.

Factory paper-advance

Paper-advance settings
specific to each paper category.
This is a baseline for the
printer, to which the other
calibrations add a correction.

Hard-coded in printer Automatically triggered by

Used with paper types, such as
films, with which OMAS cannot
be used.

The paper advance is normally managed by a combination of automatic paper-advance calibration and OMAS
tracking of the paper movement.

Printhead alignment

For printhead alignment to work best with all kinds of plain paper, it is recommended to perform the
alignment using HP Coated or HP Bright White papers. Vertical line straightness with other plain papers (such
as non-HP plain papers and recycled papers) will improve.

OMAS calibration Automatic paper-advance

This is a dynamic correction
applied to every advance

readings. It is applied to the

Mandatory for fiber-based
papers printing with relatively
few passes. Does not work with
natural tracing paper. Optional
for other papers, such as
heavyweight or glossy.

Manual paper-advance

This is an offset applied to the
other paper-advance
calibrations.

Triggered by user only

May be used by customers to
fine-tune the paper advance.
Also useful for natural tracing
paper, with which automatic
calibration does not work.

The printheads must be aligned whenever a new printhead is installed, and should be aligned after any paper
jam that may have moved the printhead slightly.

2 Chapter 1 Printing tips and tricks ENWW

Use of multiple rolls

There are various ways to set up the printer for multi-roll printing, using the roll-switch and paper-mismatch
policies. Here are some examples.

1. Same paper type and different sizes loaded: this is typical when printing line drawings in standard sizes.

For instance, two rolls with A0 size plain paper and one roll with A1 size plain paper. Driver settings:
paper type to Any and roll to Any.

●

Roll switching policy:

◦

Minimize paper waste: Recommended setting for this workflow. With this setting, roll switch
takes precedence over autorotate. This setting minimizes the paper wasted. For instance, if
an A2 portrait is sent, the printer autorotates the A2 to fit it onto the A1 roll in landscape.
But, if a A1 portrait is sent and the active roll is A0, the printer switches to an A1 roll to save
paper.

◦

Minimize roll changes: Not recommended except for very specific situations, when the
customer wants to consume a roll faster. Autorotate takes precedence over roll switch,
which reduces overall printing speed.

◦

Use roll with less paper: Not recommended in this workflow. This setting ensures that the
roll with least paper is used up before changing to another.

●

Paper mismatch policy:

◦

Print anyway: In this case, for instance, if a A0 page is sent and no A0 roll is available, the
printer uses an A1 roll and clips the image. Recommended for a workgroup environment in
which users share one printer.

◦

Put job on hold: The printer saves the A0 page on hold in the queue and prints the next pages
in the queue that can be printed. To reprint the A0 page, the customer needs to access the
queue from the front panel or the Embedded Web Server. This setting is confusing in a
workgroup enviornment because distributed customers may not know how to access the
queue, but it can be useful in a centralized print environment to avoid clipping.

◦

Pause printer to load paper: The printer stops printing completely. This could be useful for a
centralized printing environment where project print order must be maintained—for
instance, when a project is a mix of A0, A1 and A2 in a given order. For a workgroup
environment this would not be recommended. Can be useful in a centralized print
environemnt to will avoid clipping and preserve the printing order.

2. The same setup as example 1. This time, the customer does not want to waste paper, but he does not

want the printer to stop if the document size does not match the paper size.

●

Roll switching policy: Match exact size

●

Paper mismatch policy: Put job on hold

3. Three rolls loaded, two with plain and one with glossy paper: this is typical when printing line drawings

of standard sizes and where some high-density printing is requested. Roll 1 with A0 plain, Roll 2 with A1
plain and Roll 3 with glossy. Driver settings: paper type to Any and roll to Any
set paper type to Glossy paper or roll to Roll 3.

●

Roll switching policy: Minimize paper waste

. To print on glossy paper,

●

Paper mismatch policy: Print anyway for workgroups and Put job on hold or Pause printer to
load paper for centralized printing

●

Protect roll 3, to avoid printing with glossy paper unless the roll or paper type has been explicitly
selected.

ENWW Use of multiple rolls 3

4. The same setup as example 3. This time, the customer does not want to waste paper, but he does not

want the printer to stop if the document size does not match the paper size.

●

Roll switching policy: Match exact size

●

Paper mismatch policy: Put job on hold

5. The same setup as example 3. This time, the customer is not concerned about wasting paper, and he

does not want the printer to stop.

●

Roll switching policy: Minimize paper waste

●

Paper mismatch policy: Print anyway

6. Working with HP IP Pro. This is a solution specifically designed for centralized environments managed

by an operator. With HP IP, the jobs to be printed are selected one by one, previewed and assigned to a
specific roll to print. So no automatic roll selection is used in this case. When a roll is out of paper, the
queue stops, waiting for the operator to load paper, to ensure correct page order.

Printer education and training

Before any attempt is made to troubleshoot the printer, you must have the relevant training on the HP
Designjet T7200 printer series. If you are not trained on this printer, 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.

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

ENWW Printer education and training 7

problems such as incorrect front-panel selection, driver or RIP configuration or mechanical problems. For
more information on solving print-quality problems, see

Troubleshooting system error codes

System error codes on page 37 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.

Print quality on page 137.

●

The current configuration sheet.

●

Which software application the customer is using (name, version, and so on).

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 81.

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

NOTE: Remember that certain Calibrations are required even if an Assembly has been disassembled to gain

access to another Assembly or Component.

Service calibrations on page 113.

The printer does not power on

To resolve printer power up problems, do the following.

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

read the power switch LEDs on page 14 for more information.

8 Chapter 2 Troubleshooting ENWW

How to

The printer hangs during printing and displays ‘processing’

It has been seen under certain circumstances that the printer hangs whilst printing, this may happen
immediately after printing, or only a partial print. In some cases when this occurs if the machine is restarted a
system error 79:04 is displayed, although restarting again appears to clear this error. After this point,
although the printer displays that it is in the “Ready” state, attempting to print anymore plots will once again
hang the printer, including internal demo plots.

79:04

Cause Solution

The reason for this error is that a large spooled file (11 GB for
example) has been sent to the printer and has been placed in the
disk partition which is related to the print queue. The file
completely fills up all the disk space, because of this it will never
successfully print, and so the file remains in the disk partition.
Even after restarting the printer the file remains, subsequent
print requests also fail as there is not sufficient space available in
the partition to process anything else.

Perform the following few steps to clear the error.

1. Check that the firmware is the latest available

2. Turn Off and ON the printer.

3. Set Queue to OFF.

4. Set ‘When Start Printing’ to ‘Immediately’.

Please guide the customer through the front panel of the printer
to set up the “Queue” to “OFF” and “When Start Printing” to
“Immediately”.

Wipe disk solution

If the above procedure does not clear the error, use the wipe the
hard disk procedure (Unsecure mode)

5330.22’M on page 106. This will delete all previous jobs, ICC

profiles and paper presets that were present on the hard disk.
This procedure has an advantage for the customer in that it
solves the issue without the need to wait for an onsite engineer
to come to their premises and remove and replace the HDD
(which would also have the same affect of deleting all the
previous jobs, ICC profiles and paper presets). The whole
procedure should not take more than 30-35 minutes.

Important step is that you need to select the Unsecure mode.

See Disk Wipe DoD

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 79) 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 87..

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 103.

Cover sensors are not working

To resolve cover sensor problems, do the following.

ENWW The printer hangs during printing and displays ‘processing’ 9

1. Check that the cable for the faulty sensor is not damaged and is connected correctly.

2. Replace the faulty sensor.

NOTE: Covers sensors are disabled in sleep mode, don't expect them to work in this situation.

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 Center

Platen.

3. Clean the Encoder Strip

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

calibration on page 120.

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

on page 285.

See Clean the Encoder Strip on page 452.

See Line Sensor

See Line Sensor Assembly

How to remove the Left Hub when the actuator is broken

You need a standard 90º Torx/Allen key(Torx T10 or Allen 2.5).

1. Insert the key about 20 mm between the sheet-metal and plastic parts.

2. Pull the key to the left to release the brake.

10 Chapter 2 Troubleshooting ENWW

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.

Question Answer

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

Did the paper jam occur when loading 30 inch wide media? Media may jam due to excessive friction in the opposite edge of

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

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

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

Troubleshooting shutdowns

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.

due to the paper feed brake providing more tension than needed
to the media. In this case, replace the paper feed brake. If the
problem persists; escalate to HP Support.

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.

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.

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.

ENWW Troubleshooting paper jams and printhead crashes 11

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
Pinchwheels (opening the Rear Door) 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 Pinchwheels (opening the Rear Door) and pull the paper clear.

3. Replace the spindle if broken.

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

●

Ink Smearing on the Paper.

●

Printhead crashes against the Paper.

●

Roll Paper loading problems (low probability).

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, 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:

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

the print become raised, causing the Printhead to crash against the paper. To solve the problem, try the
following.

●

Change the paper margins to 15mm, either in the Front Panel or in the Driver. If the customer is
printing PostScript images, send them a PPD file containing the extended margins of 15mm.

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

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

●

Check in the Front Panel if Ink Limiting is ON or OFF. If Ink Limiting is OFF, turn it ON.

●

Never use HP Coated Paper for High Density prints. As a substitute use HP Heavy Coated Paper.

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 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 the Ink Cartridge while the printer is Printing. Only replace/remove Ink Cartridges in
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 remove the Ink Cartridge).

34" Rice Paper not supported

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

ENWW Banding at variable extreme environmental conditions 13

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.

●

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 129.

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:

14 Chapter 2 Troubleshooting ENWW

●

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 and so on). All the functions of the Electronics Module are fully operational (Embedded Web
Server and so on).

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 15.

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.

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:

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).

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.

Job-related SE 79:04

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

A system error 79:04 caused by a print job always has 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 displays the 79:04 system error again immediately after restart. This is because the printer

tries to reprint the job, which is pending in the queue, after restart.

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

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

These types of 79:04 system errors are normally caused by jobs that have been generated by third-party
applications (RIPs, third-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 under control and has been designed taking into
consideration the characteristics of our printer’s language interpreters.

ENWW How to troubleshoot the 79:04 system error 25

Solution

As an exception to this general rule, there are certain applications that can generate their own PS code, such
as Adobe PhotoShop, Adobe Illustrator, Adobe Acrobat, Corel Draw, Freehand and 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 third-party software). In
order to identify the cause and find out a solution, these issues should always be immediately escalated to
the GBU through the GCC.

However, there are some workarounds and short-term solutions that can be tried in order to get the
customer up and running in the shortest possible time.

1. Send the job using a variety of different settings. The issue is often 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 occurs 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).

Data-related SE 79:04

The printer has a hard disk and non-volatile memory that contain databases and files that can be modified by
the customer. Some examples include:

●

The printer’s queue

●

The hard-disk partitions that contain the customer's jobs

●

The database that stores printer settings

●

The database that stores accounting information

Some of these data are accessed by the printer at start-up time, and some others are accessed as needed.

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

Cause

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

1. When the corrupt data are 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 have been cleared through a service procedure.

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

a. The printer will start up normally.

b. When the data are accessed (for example while printing, while navigating the queue or when

changing some settings), the printer displays a 79:04 system error.

26 Chapter 2 Troubleshooting ENWW

Solution

c. The printer can restart normally.

d. When the data are accessed again (typically, under the same conditions as in step b), the 79:04

system error is displayed again.

Data-related 79:04 errors are often resolved by means of hardware intervention. Since data are stored in
physical components (RAM, EEROM and hard disk), replacing these components with new ones that 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 customer using the standard tools available in the

printer.

a. Delete all jobs from the queue (from the front panel or the Embedded Web Server).

b. Reset to factory defaults to clear the customer’s configurations and calibrations.

c. Delete any non-standard paper presets 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 Embedded Web Server 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 clear all the information on the hard disk and the

different EEROMs, leaving them as they were when the printer was new.

a. Access the Service Utilities Menu.

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

c. Execute the disk wipe. This will clear all partitions on the hard disk that contain customer data,

including the partition in which 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 printer to start up. This backup firmware is a very old version.

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.

Network-related SE 79:04

The printer has built-in networking capabilities. Network settings can be set manually, but in most 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 and so on.

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.

ENWW How to troubleshoot the 79:04 system error 27

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 time or when accessing the Network Configuration section of the front panel.

●

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 in which 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 start 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 configuring the printer manually.

a. Enter the correct subnet mask and an IP address 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 built into the printer, try using an

accessory Jetdirect card instead.

User-interaction-related SE 79:04

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 simply display a 79:04 system error and force a restart. Here
are some examples (not real) that may 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 probably happen only in very specific corner cases that have not been identified during the
development or the qualification of the printer. Therefore they do not normally impact the customer
severely, as they do not affect their usual workflows.

Cause

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.

Solution

First identify the state the printer was in at the time the error was displayed. For example, an action taken
when the printer is drying can produce an error, whereas the same action when the printer is doing
something else (or is idle) may not produce any error.

When you have identified the steps that caused the error, proceed as follows.

28 Chapter 2 Troubleshooting ENWW

1. Escalate the issue to the GBU through the GCC in order to have it corrected in the firmware.

2. Recommend to customers that they try to avoid the same steps to avoid the error.

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.

Random SE 79:04 (memory leaks and concurrence issues)

Some 79:04 errors can happen randomly when the printer is 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 errors 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 labelled (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 incorrect
control of these resources are concurrence issues.

Cause

For example, 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 draw conclusions from it. If the
counter is near 0, it means that the printer is processing correctly, and if it grows too large, 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 card
and the printer try to access the counter at the same time and the code is not prepared to handle this, it may
happen that the Jetdirect cannot increase the counter because the printer is writing to it, and what’s worse, 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.

This type of 79:04 error always occurs in heavy load conditions, so the symptoms will normally follow this
pattern.

●

A printer that is 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 last
occurred 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 dependent on the customer's workflow. The most common user workflows have been
extensively tested both by HP and by our beta sites, so random 79:04 issues are most unlikely to occur

ENWW How to troubleshoot the 79:04 system error 29

Solution

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, third-party drivers, and so on).

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

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. The following information
should be obtained.

●

The front-panel settings

●

The application, and the RIP or driver that are being used

●

The application/RIP/driver settings

●

The type of output files that this application, RIP or driver is generating

●

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

●

The operating system

●

The method of connection to the printer

●

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

With this information, the environment can be replicated in order to try to find workarounds. This is also the
information that will be needed at the GBU to investigate and fix the root cause of this issue once it is
escalated.

Hardware-related SE 79:04

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 turnaround 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. However,
hardware failures in the electronics tend to produce specific system errors that point directly to the
component that is failing.

Some hardware causes that could be behind a 79:04 error are as follows.

●

Defective clusters on the hard disk. If these clusters are used to execute the firmware or to process a
job, they may produce a 79:04 error. However, most 79:04 errors that are solved by a hard disk
replacement are in fact, data-related 79:04 errors that could have been solved more efficiently and
quickly by following the recommendations for such an error.

●

Defective memory segments. If the RAM memory has some defective segments, a 79:04 error 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 PrintMech PCA. This is a highly unlikely cause, since defects in these
components will produce subsystem-specific errors.

30 Chapter 2 Troubleshooting ENWW

Cause

Solution

There’s no single set of symptoms behind hardware-related 79:04 system errors. However, there are two
relatively common causes.

●

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.

In the following procedure, perform each step as it appears in the list and move on to the next step only when
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 check the functionality of

all the electronics components.

2. Check for data-related system errors: see

3. Replace the memory.

4. Replace the hard disk drive.

5. Escalate the issue before replacing any additional parts.

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

1. Restart the printer twice. If the system error has been caused by a job in an incorrect format, restarting

twice clears the error (the first time after restart, the printer tries to print the job again, which causes
the error to re-appear). If restarting the printer twice solves the issue, then it is an issue related to the
job: see

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

Since the printer cannot start normally, you must update the firmware while starting the printer in
Diagnostics Boot Mode.

3. Disconnect the network cable and restart the printer. If this solves the problem, then it is a network-

related 79:04 error and you should follow the guidelines for this type of 79:04 error, see

related SE 79:04 on page 27.

Job-related SE 79:04 on page 25.

Data-related SE 79:04 on page 26.

Network-

4. Remove all cartridges, printheads and the maintenance cartridge. Unload the paper. 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.

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, see

on page 26.

7. 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).

ENWW How to troubleshoot the 79:04 system error 31

Data-related SE 79:04

8. If the issue is new and the issue happens since the first boot, do not replace the Hard Disk Drive.

9. 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 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)

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 of error, see

related SE 79:04 on page 26.

7. Format the Hard Disk. 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, see

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

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

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 third-party application that does not print through the HP driver, try modifying the

printing workflow by:

a. Using an HP driver

b. Changing the settings in the application’s printing dialog

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

available).

7. Escalate the issue, providing 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

●

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 third-party application that does not print through the HP driver, try modifying the

printing workflow by:

a. Using an HP driver

b. Changing the settings in the application’s printing dialog

6. Escalate the issue with the following information:

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

LEDs on page 14 and How to read the Formatter LEDs on page 15.

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 /

Continuable and non-continuable error codes

Some of the Error Codes are continuable, which means you can press OK on the front-panel and continue
working with the printer. Non-Continuable Error Codes do not allow you to continue working with the printer,
in this case power the printer OFF and ON again and see if the System Error disappears. If the Error Code
reappears, then the printer requires an on-site visit in order to resolve the problem.

NOTE: If the solution calls for a replacement part, replace one component at a time and check if the error

has been cleared before replacing another component. Using this procedure you will be able to determine
exactly which component has failed.

What are ink supplies?

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

Ink Cartridges

The color printer's six Ink Cartridges provide matte black, dark gray, gray, magenta, cyan and yellow ink to
the Printheads. The Introductory Ink Cartridges supplied with the printer have 225 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 400 ml, and there is also a
larger Matte Black Ink Cartridge that holds approximately 775 ml.

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 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 table lists the Ink Cartridges for the HP Designjet T7200 printer series.

NOTE: This list is likely to change over the course of time. For the latest information, see HP Designjet Ink

for HP Designjet T7200 Printer Series at:

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.

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

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 138.

ENWW What are ink supplies? 71

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 color printer is the HP 761 Maintenance Cartridge, part number CH649A.

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:

●

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.

72 Chapter 4 Ink supplies ENWW

●

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:

●

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.

1. Ensure that you have the correct HP 761 Maintenance Cartridge.

2. Ensure that the Maintenance Cartridge is in the correct orientation.

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”.

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.

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 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; see

on page 37.

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.
