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:
D D D D D D D D
Model and Serial Number of the printer. Which firmware revision the printer is using. The complete error number. The Service Print (Utilities / Service Tests). 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..
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.

Ready + Align Media + Load Media + Cartridges: Memory or Accuracy Calibration Problems. Possible causes: D Not enough memory for the current plot. Add extra memory by installing a bigger RAM SIMM. Refer to Chapter 7 for the correct part numbers of the RAM SIMMs. If this error code appeared while performing the Accuracy Calibration: D 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. D 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. D 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. D Faulty Trailing Cable. D Faulty Carriage Assembly. D Faulty Electronics Module. Ready + Load Media + Cartridges: Mechanical Problem. Possible causes: D Check the Bail Assembly. D Check the Capping Position in the Service Station.

Ready + Align Media + Load Media + Media: Error in bail lift mechanism. The bail lift 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.) Possible causes: D Check the bail lift system to see if it is working correctly. D Use the bail cycle test to help troubleshoot.

Ready + Data + Media: Error in X axis calibration. Possible causes: D Is X axis calibration done? (details ' Chapter 5) 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 drive roller gear; if alignment is incorrect, the problem may be in the carriage. Load Media + Data: Firmware has a problem interacting with some of the characteristics of the print. The Printer is using an old Firmware revision Install the latest firmware revision. D If this error remains, report the problem to your HP Response Center. Note conditions and actions before error occurred. Include setup sheet and service configuration plot in report.

Align Media + Cartridges + Data: Model ID not configured. D After replacing a new electronics module, it must be configured either as a DesignJet 430, 450C or 455CA. If a new module does not show this error, it means that it has been installed previously and was probably calibrated with other parameters. After configuring the module Error code Steady DLM will appear which means the accuracy calibration must be done. After the accuracy calibration is done, all other calibrations must be done. If configuring the module does not remove the error, even after switching the Printer OFF and ON, then the EEROM in the main PCA is probably defective. Before trying to replace the electronics module try clearing the EEROM and perform all the calibrations again and see if that solves the problem. Refer to page 4 27 in order to configure the correct model ID. For more information ' page 1 8.

Align Media + Media: Y axis Shutdown. Possible causes: D Problems with the Cutter Assembly. D Clear any binding due to a media jam. D Turn the Printer off. Manually move the carriage along the carriage axis. Check for any areas where the carriage may be binding. D Ensure that the belt and belt pulley are in correct working order. Remove dirt from the pulley that could cause the belt to slip. D Perform the carriage axis test and the servo/encoder test to check for problems with the carriage motor, encoder strip, and electronics module. D Remove dirt from the slider rod and chassis beam. Apply oil (Anderol 4068, HP part number: 6040 0858) to the carriage bushings. D At high temperatures, and if the fan is not working correctly, the internal resistance of the motor driver may increase, causing a decrease in the voltage between the motor contacts, and a shutdown of the motor. D Ensure that the encoder strip is not inverted, damaged or absent. D Reconnect or replace the trailing cable ' page 8 8. D Replace the carriage assembly ' page 8 37. Ready + Align Media + Media: Y axis Movement Error. Possible causes: D Something is causing excessive friction in the Y axis (carriage axis). D The carriage touches the bail as it moves.
