Chapter 1 Troubleshooting

Guide to Troubleshooting the Printer

Introduction

This chapter will guide you through the relevant steps to take when
troubleshooting the printer.

Troubleshooting System Error Codes

Chapter 2, System Error Codes contains a list of system error codes and
their respective descriptions and recommended corrective actions. Only try
one recommended action at a time and check if the error code has
disappeared.

If you have an error code which is not documented in this Service Manual or
you have an error which you cannot resolve, then report the error to the HP
Response Center or the nearest HP Support Office. When reporting the
error, have the following information ready:

 Model and Serial Number of the printer.
 Which firmware revision the printer is using (See Note below). Check

firmware in Utilities / Statistics / Code rev.

 The complete error number (See Note below).
 The Service Configuration Print.

The Current configuration sheet.

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

When reporting the System Error Code, make sure that you
supply the full Error Code and the firmware version.
Without this information, HP Support Personnel cannot help
you.

Performing a Service Test on a failed Assembly

If possible, always perform a Service Test on the component/assembly that
you are about to replace, just to make sure that is the component/assembly
that has failed.

If the test on that component/assembly passes, you should
NOT replace it.

For information on the Service Tests and how to use them see Chapter 4,
Service Tests and Utilities.

Guide to Troubleshooting the Printer - Performing the Necessary Service Calibrations

Performing the Necessary Service Calibrations

Is the printer calibrated correctly after replacing a component? For
information on the Service Calibrations and how to use them see Chapter 5,
Service Calibrations.

Remember that certain Calibrations are required even if an
Assembly has been disassembled to gain access to another
Assembly or Component.

Solving Print Quality Problems

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 information on solving Print Quality problems see Chapter 6,
Print Quality.

The Printer does not Power ON

1 Check that the power cord is connected correctly to the Printer and to the

Power Socket.

2 Check that the Power Switch on the BACK of the Printer is in the ON

position.

3 Check to see the LED on the Front Panel Power Switch are On.

4 Check that the Front-Panel Cable is correctly connected to the Electronics

Module. Also make sure that the Front-Panel cable is not damaged.

5 Replace the Power Supply Unit

⇒ Page 8-144.

The Printer Continuously Rejects Printheads

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

the Carriage Interconnect Wiper (Refer to Page 3-20) and try again.

2 If ALL the Printheads are rejected (the status message on the Front Panel does

NOT show "OK" for ALL the Printheads) then perform the Electronic Module
Test

⇒ Page 4-21.

Cover Sensors are not Working

1 Perform the Sensors Test ⇒ Page 4-31.

2 Check if the cable for the faulty sensor is not damaged and is connected

correctly.

3 Replace the faulty Sensor.

The Line Sensor has Problems Detecting Media

1 Check the type of media that is being used since the Line sensor may have

problems detecting transparent media or some types of Non-HP media. Try

HP Designjet T1100/T1100ps/T610 Printer Series — Service Manual 1-3

Chapter 1 Troubleshooting

loading white HP media in to the Printer and check if the Line sensor detects
it.

2 The Line Sensor is not calibrated correctly. Perform the Line Sensor

Calibration ⇒ Page 5-15.

3 The Line Sensor is damaged or faulty. Replace the Line Sensor ⇒ Page 8-

115.

Troubleshooting Media Jams/Printhead Crashes

The failure modes "media jam" and "head crash" are grouped together
because in many cases a media jam causes the media to lift up into the
Carriage path and cause a Printhead crash, thus causing many media jam
failures to be reported as head crashes.

1 Did the media jam occur when loading media?

 If the client has had media jams, it is common for pieces of media to get

When clearing a media jam, sometimes media is stuck in
the paper path. To clear this, you must lift the Media Lever
and insert thicker media into the paper path to push out the
media that is still stuck there.

stuck in the media path. Clear the media path.

2 Is the customer using non-HP media?

 The use of non-HP media can easily be the cause of media jams and

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

Banding at variable extreme environmental conditions

Since the Accuracy Calibration has been done at normal environmental
conditions, printing in extreme environmental conditions will cause banding
because the advance of the Media Advance Roller does not correspond to
the same conditions that the calibration was done in. To solve the problem,
try the following:

Perform the Accuracy Calibration in the new environmental conditions (Refer
to the User’s Guide).

Worm marks on HP Coated media with light area fills

Light bands (S-shaped) in Paper axis direction where light area fills are
printed, causing unacceptable Image Quality defect.

 Print the Service Configuration Print and check if the level of Humidity is

very low (below 30%). Increasing humidity may help in reducing the

1-4 HP Designjet T1100/T1100ps/T610 Printer Series — Service Manual

Guide to Troubleshooting the Printer - Solving Media-Handling Problems

severity of the problem.

The media is causing the problem and NOT the Printer. Do
not attempt to try and replace Printer parts to solve this
problem.

Solving Media-Handling Problems

The Front Panel indicates that media is misaligned or incorrectly positioned

Roll media

Sheet media

 The roll may be loaded the wrong way. The paper should load over the

roll toward you.

 Check that the paper is correctly loaded onto the spindle.
 The paper may be loaded at an angle. The right-hand edge must be

aligned with the blue line on the Print Platen.

With 24 inch printers, ensure that the paper is wrapped
tightly on the roll. This is a very important step to remember
because if this is not done, the media may be loaded at an
angle, causing the media to be rejected.

 Check that the Right Spindle Holder (rewinder included) is properly

attached and screwed to the printer.

For 44 inch printers, the Rewinder, located on the Right Spindle Holder
(rewinder included), should maintain proper back tension. If the Right
Spindle Holder (rewinder included) is misaligned or not properly
attached to the printer, the Rewinder will not function properly.

A graphic of a properly installed Rewinder can be found on page 8-74,
Right Spindle Holder (rewinder included). To further diagnose problems
with the Rewinder, Refer to Page 4-34.

 Always load sheet media using the Rear Input Tray. Do NOT load the

media as you would load roll media.

 It must be loaded with the right-hand edge against the blue line on the

Print Platen.

 The media may be crumpled or warped or may have irregular edges.
 If hand-cut media is used, the edges may not form a right-angle or they

may be rough. If possible, hand-cut media should not be used. Only
purchased sheet media should be used in the Printer.

 If you have problems with paper jams, check that the Overdrive is not

obstructed by bits of paper or using the Turn Drive Roller Service Utility
Page 4-58.

Check that the Right Spindle Holder (rewinder included) is properly attached
and screwed to the printer.

⇒

For 44 inch printers, the Rewinder, located on the Right Spindle Holder

Chapter 1 System Error Codes

Introduction

System error codes are hexa-decimal based numbers generally caused by
internal system errors. The following pages contain a list of system error
codes and their respective descriptions and recommended corrective
actions. Only try one recommended action at a time and check if the error
code has disappeared.

If you have an error code which is not documented in this Service Manual or
you have an error which you cannot resolve, then report the error to the HP
Response Center or the nearest HP Support Office. When reporting the
error, have the following information ready:

 Model and Serial Number of the printer.
 Which firmware revision the printer is using (See Note below). Check

firmware in Setup Menu / Information Menu / Show Printer Information.

 The complete error number (See Note below).
 The Service Configuration Print.

The Current configuration sheet.

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

When reporting the System Error Code, make sure that you
supply the full Internal Error Code and the firmware
version. Without this information, HP Support Personnel
cannot help you. To view the Internal Error Code, hold the
UP key and press the CANCEL key at the same when the
System Error.

Code is displayed on the Front Panel.

This is the code definition required
when escalating a problem

Continuable and Non-Continuable Error Codes

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

Even though the customer can continue working with a
Continuable Error Code, an on-site visit should still be
planned to troubleshoot the problem.

Introduction to Ink Supplies

What are Ink Supplies?

For each of the ink colors used in the printer, there are two components, the
Printhead and Ink Cartridge. These components are called Ink Supplies.

Introduction to Ink Supplies - What are Ink Supplies?

Ink Cartridges

Printheads

Ink Cartridges

The printer's six Ink Cartridges provide matte black, magenta, yeloow, cyan,
gray and photo black ink to the Printheads. The color Ink Cartridges
supplied with the printer have a capacity of 69ml but optional 130 ml are

also available

.l

All these Ink cartridges are physically the same size. Only
the internal capacity varies.

The Ink Cartridges for the T1100/T1100ps/T610 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.

routine process, when all printheads are changed, takes 25 minutes. If the
printer finds problems in preparing the printheads, it will take longer, up to
55 minutes. For a single printhead insertion, the times vary between 15 and
35 minutes. After all printheads are checked and prepared, for the
printhead realignment.

Aligning Printheads

Precise alignment between printheads is essential for accurate colors,
smooth color transitions, and sharp edges in graphical elements. Your
printer has an automatic printhead alignment process which runs whenever
a printhead has been accessed or replaced.

In cases where the paper has jammed, you have used a custom paper, or
are experiencing problems with color accuracy you may need to align the
printheads. If the paper has jammed, it is recommended that you reinsert the
printheads and initiate the realignment procedure with the Image Quality

Maintenance menu.

Do not use transparent and semi-transparent paper to align
the printheads. Photo paper is recommended for the best
quality.

Reinsert Printheads Procedure

1 If the realignment process is running and the wrong paper is loaded, press

the cancel key on the front panel. Do not print if the realignment process has
been canceled. You can restart the alignment with the Image Quality
Maintenance menu procedure.

2 Load the paper you wish to use,. You can use a roll or cut sheet, however, it

must be A3 landscape or larger.

3 Remove and re-insert all the printheads, see Remove a printhead and Insert

a printhead. This will start the printhead alignment procedure.

4 Ensure the transparent window closed, as a strong light source near the

printer during printhead realignment can affect alignment.

5 The process will take about six minutes. Wait until the front panel display

shows the process complete before using the printer.

Image Quality Maintenance Procedure

1 Load the paper you wish to use. You can use a roll or cut sheet, however, it

must be A3 landscape or larger (420 by 297 mm). Do not use transparent
and semi-transparent paper to align the printheads. Photo paper is
recommended for the best results; plain, bond and thin coated papers
provide acceptable but marginal results.

2 Press the Menu key to return to the main menu and select the Image Quality

Maintenance menu icon.

3 Select Align printheads. The printer will check to see if it has enough paper

to run the realignment.

4 If the loaded paper is satisfactory, the printer will run the realignment and

print a realignment pattern. Ensure the transparent window is closed, as a

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

T1100/T1100ps/T610 Plot:

5 The process will take about five minutes. Wait until the front panel display

shows the process complete before using the printer.

Scanning errors during alignment

If the alignment process FAILs, a Scanning problems message appears on
the front panel. This means that the alignment has not completed
successfully. Therefore the printer is not aligned and the alignment should be
repeated before printing with good image quality. The problem may be due
to:

 The paper used was not valid, repeat the alignment with valid paper.
 Printhead health problems, clean printheads.
 The alignment was done with the transparent window open, repeat the

alignment with the window closed.

If the problem persists after using valid paper, cleaning the printheads, and
keeping the window closed, there may be a Failure in the scanning system
needing reparation or the printheads, although clean, may not work and
need to be replaced.

Ink Cartridge and Printhead Status Messages

Ink Cartridge Status Messages

OK The Ink Cartridge is operating correctly and no action is required.

Missing There is no Ink Cartridge present, or it is not properly connected to the

printer

Low The Low message is an early warning sign and it is advisable that new

supplies should be obtained of that particular color. The amount of ink
remaining in the Ink Cartridge depends on it’s capacity, but there is
approximately 14% of ink available for the user.

Very Low When the Very Low message is displayed, overnight printing should not

be attempted. Changing the Ink Cartridge is strongly recommended to
prevent the printer from stopping halfway through a print. There is
approximately 8% of ink available for the user.

Empty The printer will stop and will not be able to continue printing until a new Ink

Cartridge has been installed. If this occurs halfway through printing an
image, you should check the quality of this image, as stopping mid-plot can
affect the print. It would be recommended to reprint the image once a new
Ink Cartridge has been installed.

Reseat You are recommended to remove the Ink Cartridge and then reinsert it.

Replace You are recommended to replace the Ink Cartridge with a new Ink

Cartridge.

Altered There is something unexpected about the Ink Cartridge's status.

Chapter 3 Ink Supplies Troubleshooting

Maintaining and Cleaning the Printheads

Clean the printheads

As long as the printer is kept turned on, an automatic cleaning is performed
periodically. This ensures there is fresh ink in the nozzles and prevents
nozzle clogs, which ensures color accuracy.

If you have not already done so, please refer to Horizontal lines across the
image (banding) and The Image Diagnostics Print before proceeding.

To clean the printheads, press the Menu key to return to the main menu and
select the Image Quality Maintenance menu icon, then Clean printheads. If
you have gone through the Image Quality Diagnostic print process, you
know which colors are failing. Select to the pair of printheads which contain
the failing colors. If you are not sure which colors to clean, you can also
select to clean all printheads.

Cleaning all printheads takes about nine minutes. Cleaning a single pair of
printheads takes about six minutes. Cleaning all printheads uses more ink
than cleaning a single pair.

If you have cleaned the printheads using the Clean printheads procedure
from the front panel and are still experiencing image quality problems, you
can try cleaning the printhead nozzles manually using the following

procedure.

This is a delicate process and may damage the printhead.
Do not touch the electrical connections on the backside of
the printhead.

You must remove the printhead (see Remove a printhead) and using a cotton
swab and a little de-ionized, distilled water, or Carriage Interconnect Wiper
clean the bottom of the printhead until the residue is removed.

Flex Contacts Cleaning Tool

The Flex Contacts Cleaning Tool is part of the Maintenance
Tool Kit which can be ordered using Part Number Q5669-

60690. All the instructions needed to use the Flex Contacts
Cleaning Tool will be packaged with the kit.

Whenever you replace the Printhead, check the empty slots to see if they
need cleaning. In extreme circumstances, when a Printhead is inserted, it is
possible that the Printer will not recognize it due to the build-up of ink on the
electrical connection between the Printhead and the Carriage Assembly.

3-20 HP Designjet T1100/T1100ps/T610 Printer Series — Service Manual

Maintaining and Cleaning the Printheads - Flex Contacts Cleaning Tool

Included with the T1100/T1100ps/T610 Printer is a Flex Contacts
Cleaning Tool. This tool is provided in a separate package. It 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 using the Carriage Interconnect Wiper.

Do not touch, wipe or attempt to clean the printhead
nozzles. This can damage the printhead and reduce print
quality.

The Service Tests work in a special Mode which does NOT
require the full Initialization of the Printer. Therefore it is
important that once you have finished with the Service
Tests, you MUST power OFF the Printer and Power ON
again before trying to print or before executing another
Service Test.

In some cases a quick press of a button may not be
recognized by the Printer. When pressing a button, be sure
to press it deliberately and all the way to the bottom of its
travel.

If the Printer hangs up during a test, switch the Printer OFF
and restart from step 1.
