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 (rewinder included), should maintain proper back tension. If the Right

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.

 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.
