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. Make sure that the trailing cable is positioned under the plastic tabs at the back of the carriage cover, and not above them.
If you are in Service Mode 1, the cover sensor is disabled. If the media is not HP approved, advise the customer to use HP media and check to see if the problem is now solved. A charge can cause the media to stick to itself and jam the Printer. Check and if necessary adjust the carriage0to0media distance ' page and try to load the media again. Remove the Drive Roller and install in the correct position ' page and try to load the media again. Make sure that the Clutch assembly is installed correctly and is not faulty.
Make sure that all the starwheels on the bail assembly are correctly installed and turn properly. Make sure that all the Media deflectors are installed on the Printer, otherwise there could be media crashes. If nothing appears on the front0panel display, then replace the Electronics Module ' page If the Printer does Power On with the cables disconnected, then the problem must be with another component of the Printer.
Once the faulty component is connected, it will not allow the Printer to power ON. This component should then be replaced. What can I do if the Printer has problems with Media Loading? If necessary, perform the Carriage Test ' page Perform the Accuracy Calibration ' page 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? D Check 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. D Make 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.
D Make sure that there is no media trapped inside the Cutter mechanism. Remove the Cutter to inspect it correctly. D Remove 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. D If 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.
This can happen due to excessive wearing of parts. Another problem may be that the bail cable has broken. 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. This can happen if the cam is over or under2rotated. Perform a bail cycle test. Details ' page However, be careful not to jeopardize the print quality, which is very sensitive to the carriage angle. 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:. D Faulty electronics module. D Contact problems with the trailing2cable connections. It is generally not easy to discover the cause, due to the intermittent character of the failure modes. 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. In other cases, 2ou need to find the cause:.
D If it is eas2 to reproduce a Steady EKL error, then tr2 one or all of the following steps for a possible solution:. Then turn it on again and allow it to initialize. Replace the electronics module.
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:.
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.
On Steady. The following pages contain the possible error codes and the instructions necessary to solve the problem. An error which the customer could probably solve, like a paper jam, minor cartridge problem etc. Use the error codes below to find information on the subcode.
This error code indicates a severe problem which will require a Service Engineer to troubleshoot. Not enough memory for the current plot. Check that the quality of the Accuracy Calibration print is good. If the quality is bad, try to clean the black cartridge or replace it. Make sure that you load the Accuracy Calibration print in the correct position and orientation, and make sure that you select the correct media type.
Make sure that the line sensor on the carriage is clean. If the Line sensor is dirty or not functioning correctly, it will have problems reading the accuracy calibration print. The bail1lift system is unable to raise or lower the bail. It is the carriage that tests to see whether the bail is in the correct position by trying to knock against it. D Check the bail1lift system to see if it is working correctly.
D Use the bail cycle test to help troubleshoot. D Is X1axis calibration done? D Did you load media in correct orientation? D Are the marks visible on the plot? If not, check cartridges. D Are cartridges correctly aligned? If so, the problem may be in the electronics module, media motor or drive1roller gear; if alignment is incorrect, the problem may be in the carriage. The Printer is using an old Firmware revision 1 Install the latest firmware revision. Note conditions and actions before error occurred.
Include setup sheet and service configuration plot in report. The drive roller has shifted slightly from the expected position mechanics. Check that the carriage sensor lights just over the white mark on the drive roller when starting.
Problems in the Centronics Communications. Probably due to the bad contacts of the connector. If this error remains, report the problem to your HP Response Center. D a,,iage a--embl2 i- no. D Incorrect routing of the motor cables. D Electrical noise in motors. D Motor received an electrostatic discharge while operating. D Damaged or broken encoder strip. D Faulty or badly connected trailing cable. D Trailing Cable received an electrostatic discharge while the Printer was operating. D Faulty Electronics Module.
They tell you the printer's current status and, if there is an error, the nature of the error. In order to understand the meaning of each combination of lights, you should check the table in this chapter to help you to understand the meaning.
You will therefore find this table useful in troubleshooting. 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. The Printers automatically perform a series of internal self tests and mechanical initialization sequences whenever the user switches the Printer on. You can perform a failure analysis by interpreting the LED error code.
Details ' Chapter 2. The following is a list of all internal service tests available in the Printers.

You can view this information on the service configuration plot. The service monitor is useful to find out why the Printer is not plotting what you expect it to plot. It enables you to read the graphics9language instructions that the Printer is receiving from the computer.
Instead of plotting the drawing that you send, the Printer prints the beginning and end of the code that would otherwise have been used to plot the drawing.
Service Mode 1 contains tests that do not need a complete initialization of the Printer This means if there is a system error in normal mode it is still possible to enter into Service Mode 1 Also the Sensors are disabled in Service Mode 1 which means it will not be possible to load media The only time that the sensors will be functional is during the Sensors Test. The Electronics Test is continuously done in the background during Service Mode 1. If you are viewing information via the serial port, you will see output similar to the following:.
The service tests are continuously repeated until you stop them To exit a test press the Cancel and Media Source keys some tests may take a short while before exiting To exit Service Mode 1 you must power OFF the Printer. Some of the tests in service mode 1 send test information to the printer s serial port. To view the information via the Serial Port:.
To stop communication between the Printer and the Palmtop, highlight Hangup in the Connect menu and press. This tests the operation of the bail system, Service Station and the Y. This Test has been designed to be used during the manufacturing stage and not in the field.
