What can I do if the Line Sensor has Problems Detecting Media?

1Excessive ink deposits on the drive8roller surface can fool the sensor by reflecting the light. lean the drive8roller ' hapter 9.

2Line sensor incorrectly calibrated: The accuracy calibration includes calibration of the line sensor on the carriage. You must use P Matte film when performing the accuracy calibration ( etails ' hapter ).

Otherwise the line sensor will have problems loading some types of media.

3 The Line Sensor is faulty. Replace the arriage Assembly ' page 8837.

What can I do if the Carriage is Noisy?

1irty arriage bushings. Remove dust particles from the arriage bushings and from the slider rod along which the arriage moves. If necessary, apply lubricant to the slider rod.

2 Make sure that the belt is correctly positioned on the Y8axis motor.

3 Remove dust particles from the Back Beam and, if necessary, apply grease.

4 heck for a faulty arriage. Perform the arriage Axis Test ' page 4810.

What can I do if the Cover Sensor isn't Working?

h n i h n n

1Before troubleshooting, make sure that you are not in Service Mode 1 because the over sensor is disabled and Printer will think that the cover is always closed. Power OFF the Printer and switch it back ON again and check if the over sensor works.

2heck if the cable for the front8panel assembly is connected correctly to the electronics module.

3 Replace the front8panel assembly ' page 8812.

What can I do if the Carriage Assembly has problems parking in the Service Station?

1Mispositioned trailing cable: The trailing cable may be preventing the carriage from reaching the left8hand stop. Make sure that the trailing cable is positioned under the plastic tabs at the back of the carriage cover, and not above them.

2The arriage is not at the correct height. heck and, if necessary, adjust the arriage height ( etails ' chapter ).

Troubleshooting

What can I do if the Printer continuously rejects Cartridges?

If you are in Service Mode 1, the cover sensor is disabled. In order to test a new Cartridge set, the Printer must be powered OF and and ON again.

1Remove tape and align cartridges: One frequent cause of cartridge problems is that the user has forgotten to remove the tape from new cartridges Remove the tape

2Dirty pads: The connection between the carriage PCA and the cartridge flex connector is made by means of a gold bubble on the flex connector that touches a gold pad on the PCA The Carriage Test details ' page 49 2 includes a test of this connection When nozzle failures occur clean the flex contacts on the cartridge and in the Carriage

3Continuity Problem: Remove all the cartridges from the Carriage and try installing just the rejected cartridge If the cartridge is still rejected then replace the cartridge with a new one If the new cartridge is not rejected then check one by one if the other cartridges are rejected or not

4Faulty cartridge: Some black cartridges 5 64 A with USE BEFORE dates of April 96 and earlier may have thin9film damage This means that the material used for channeling ink behind the nozzles can crack with aging When this happens ink seepage may cause many nozzles to fail eight or more Replace the black cartridge with one with USE BEFORE date of ay 96 or later

5If the Cartridges are not inserted correctly into the Carriage the Cartridges will be rejected ake sure that the springs that hold the Cartridges in the Carriage are not broken or misplaced

6 Perform the Carriage Test ' page 49 2

7 Replace the Trailing Cable ' page 898

8 Replace the Carriage Assembly ' page 8937

What can I do if the Media continuously crashes?

1Check if the media loaded is HP approved. If the media is not HP approved, advise the customer to use HP media and check to see if the problem is now solved.

2Anti&static brush: If this brush (located under the entry platen) is damaged or removed, static charge can build up on the media. A charge can cause the media to stick to itself and jam the Printer.

3The Carriage is at the incorrect height in relation to the Drive Roller. Check and if necessary adjust the carriage0to0media distance ' page 505 and try to load the media again.

4The Drive Roller is installed incorrectly. Remove the Drive Roller and install in the correct position ' page 8044 and try to load the media again.

5The overdrive wheels turn free in both directions, creating bubbles in the media. Make sure that the Clutch assembly is installed correctly and is not faulty.

6Missing or damaged starwheels. Make sure that all the starwheels on the bail assembly are correctly installed and turn properly.

7Missing Media Deflectors. Make sure that all the Media deflectors are installed on the Printer, otherwise there could be media crashes.

What can I do if the Printer does not Power ON?

1 Check that the power cord is connected correctly.

2Check that the ROM SIMM (firmware) is installed correctly in the correct slot (the slot furthest from you) at the back of the Printer.

3Try to disconnect all the cables, apart from the Front Panel Cable, from the Electronics Module and then try to power ON the Printer again. If nothing appears on the front0panel display, then replace the Electronics Module ' page 8013. If the Printer does Power On with the cables disconnected, then the problem must be with another component of the Printer. To find the faulty component, power OFF the Printer and connect one of the cables and power ON again. Once the faulty component is connected, it will not allow the Printer to power ON. This component should then be replaced.

Troubleshooting

What can I do if the Printer has problems with Media Loading? 1 Check that the Media Sensor is installed correctly.

2 Check if the cable for the Media Sensor is connected correctly.

3 Check if the Pincharms are down (the Pincharm lever should be up).

4If the media is continuously rejected during the media edge check, then make sure that the Line Sensor is installed correctly. If necessary, perform the Carriage Test ' page 4112.

5Make sure the line sensor is calibrated. Perform the Accuracy Calibration ' page 12.

6 Replace the Media Sensor (part of the overdrive assembly) ' page 81 0.

7Replace the Carriage Assembly ' page 8137.

Only replace one component at a time and check if the problem has been solved before replacing another component Using this procedure you will be able to determine exactly which component failed

What can I do if the Printer has problems with the Cutter? 1 If the Carriage Assembly has problems picking up the Cutter:

DCheck that the cable for the Front1Panel Assembly is is not loose and is routed correctly in the cover clips. A loose cable can be trapped by the Cutter, preventing the Cutter from moving.

DMake sure that the Spittoon Assembly is correctly installed and is aligned with the Overdrive Assembly. If the Spittoon is loose or mispositioned, the cutter will have problems parking in the right cover.

2 If the media crashes when moving the Cutter:

DMake sure that there is no media trapped inside the Cutter mechanism. Remove the Cutter to inspect it correctly.

DRemove the Cutter and make sure that both rotary blades are touching each other by the flat sides and not the sloping sides. If the rotary blades are touching each other by the sloping sides, you must reseat them.

DIf the Printer is placed on a table, it must be placed as close to the edge as possible to make sure that the media that is coming out falls correctly. If the Printer is in the middle of the table, the media that is coming out will be lifted up causing the cutter to crash into it.

What can I do if the Bail Mechanism Fails?

1Obstructions: Check that there are no obstructions in the way of the Bail Assembly.

2Wearing of parts: The cam gear and engaging gear may not make correct contact with the left drive2roller gear even though the carriage is actuating the engaging lever. This can happen due to excessive wearing of parts. Another problem may be that the bail cable has broken.

3Carriage motor control: The carriage may not properly locate the engagement lever, preventing the gears from engaging. Any problems with the carriage2motor control system (for example, the encoder strip) or associated mechanics could cause this problem. Also, if the carriage cannot find the true left stop during initialization (caused by interference), the engaging lever cannot be located.

4Bail cam: The bail may fall from the up position. This can happen if the cam is over or under2rotated. The notch on the cam, used to engage the left bail bracket, is not properly located for the •bail up" condition, and the bail falls abruptly. Perform a bail cycle test.

5Adjust carriage: If the carriage moves over the engaging lever without raising it, you may need to adjust the carriage angle on the slider rod. (Details ' page 525.) However, be careful not to jeopardize the print quality, which is very sensitive to the carriage angle.

EEROM Errors

What is an EEROM error?

An EEROM error means that some of the internal tests that the firmware performs have detected that, when re2reading information from the EEROM, it doesn't correspond to the information that had previously been written there, or that the checksum of all the information is incorrect. This failure has five possible causes:

DFaulty electronics module.

DContact problems with the trailing2cable connections.

DFaulty trailing cable.

DFaulty carriage.

DThe Printer was turned off while a test was writing to the EEROM, thus leaving corrupt information (or a communication cable was disconnected while sending information to the EEROM using software diagnostic tools).

It is generally not easy to discover the cause, due to the intermittent character of the failure modes.

Troubleshooting

If 2ou are sure that the failure occurred just after an electricit2 power4cut, or after turning off the Printer during the bench run or other service tests, then the Printer is not fault2. You just need to reset the EEROM. In other cases, 2ou need to find the cause:

DThere is alwa2s an EEROM error when 2ou switch on the Printer:

DIf it is eas2 to reproduce a Steady EKL error, then tr2 one or all of the following steps for a possible solution:

1 Configure the EEROM with the correct model ID (instructions ' page 4427).

2If 2ou cannot configure the EEROM with the correct model ID after several attempts and 2ou continue getting the same error code, replace the electronics module ' page 8413.

DThere is sometimes an EEROM error when 2ou switch on the Printer (normall2 shows up as a Steady EK error):

1 Switch on the Printer, allow it to initialize until it has completed the power4on LED sequence, and switch off the Printer. (You are now sure that the EEROM has not been corrupted. If a Steady EK error appeared, it also corrects the EEROM contents, and the next time 2ou switch the Printer ON, the error should not occur in good units.)

2Leave the unit off for 15 minutes to detect if the EEROM is losing its information. Then turn it on again and allow it to initialize. If a Steady EK error appears during the initialization sequence, and the carriage does not begin to move, then the EEROM is probabl2 fault2. Replace the electronics module.

System Error Codes

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.

The complete error number.

The Service Print (Utiliti s / S rvi T sts).

The Current configuration sheet.

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

Is the problem reproducible by you?

Additional comments about the usage, the setting, etc..

Import nt Inform tion on Trou leshooting Error o es

Before spending time troubleshooting the problem by doing the various tests or replacing parts (which may not need replacing), check which firmware revision the printer is using or check if a service note deals with this particular problem. Some problems which occurred in earlier firmware releases may have been solved in later revisions. So if there is a new firmware revision then update the ROM SIMM before replacing any parts. Refer to Chapter 7 for the part number of the ROM SIMM.
