What can I do if the Bail Mechanism Fails

1 Obstructions Check that there are no obstructions in the way of the Bail Assembly. 2 Wearing of parts The cam gear and engaging gear may not make correct contact with the left drive-roller 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. 3 Carriage motor control The carriage may not properly locate the engagement lever, preventing the gears from engaging. Any problems with...

Important Information on Troubleshooting Error Codes

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. GO paper HO...

Only replace one component at a time and perform the test again before replacing another component Using this procedure

The bench run is a routine that each Printer performs before it leaves the manufacturing site. It attempts to filter out Printers that could have an early breakdown due to a fault in manufacturing. The bench run tests the operation of the electronics, carriage-axis system, media-axis system, bail-lift mechanism, and service station. The bench run is performed at the manufacturing site by sending special commands to the Printer and then pressing the indicated front-panel keys. If the Printer is...

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

1 Excessive ink deposits on the drive-roller surface can fool the sensor by reflecting the light. Clean the drive-roller t Chapter 9. 2 Line sensor incorrectly calibrated The accuracy calibration includes calibration of the line sensor on the carriage. You must use HP Matte film when performing the accuracy calibration Details t Chapter 5 . Otherwise the line sensor will have problems loading some types of media. 3 The Line Sensor is faulty. Replace the Carriage Assembly t page 8-37.

What is an EEROM error

An EEROM error means that some of the internal tests that the firmware performs have detected that, when re-reading 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 Contact problems with the trailing-cable connections. The Printer was turned off while a test was writing to the EEROM, thus leaving corrupt information or a communication cable...
