Ready + Align Media + Load Media + Cartridges:
Memory or Accuracy Calibration Problems.
Possible causes:
• 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:
• 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.
• Faulty Trailing Cable.
• Faulty Carriage Assembly.
• Faulty Electronics Module.

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:
• Check the bail-lift system to see if it is working correctly.
• Use the bail cycle test to help troubleshoot.

Ready + Data + Media: Error in X-axis calibration. Possible causes:
• Is X-axis calibration done? (details t Chapter 5)
• Did you load media in correct orientation?
• Are the marks visible on the plot? If not, check cartridges.
• 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.

Ready + Align Media + Data: Communication problem with RS-232 (Serial Port).
Possible causes:
• Incorrect configuration in communications speed/protocol.
• Incorrect communications cable.
• Error in host computer.
Ready + Load Media + Data: There is a communication problem between the Main PCA and the internal microprocessors.
The Main PCA is faulty - Replace the Electronics Module.

Ready + Cartridges + Data: Mark Encoder not detected. Possible causes:
• The line on the mark encoder is dirty or missing.
• Faulty or badly connected trailing cable.
• Faulty or badly connected carriage sensor.
• Faulty or badly connected X-axis Encoder Cable.
• 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.
• Faulty carriage PCA.
• Faulty electronics module. 
Align Media + Load Media + Data: Error reading Centronics I/O
Problems in the Centronics Communications. Probably due to the bad contacts of the connector.

Align Media + Cartridges + Data: Model ID not configured.
• 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 t page 1-8.

Align Media + Media: Y-axis Shutdown.
Possible causes:
• Problems with the Cutter Assembly.
• Clear any binding due to a media jam.
• Turn the Printer off. Manually move the carriage along the carriage axis. Check for any areas where the carriage may be binding.
• Ensure that the belt and belt pulley are in correct working order. Remove dirt from the pulley that could cause the belt to slip.
• Perform the carriage-axis test and the servo/encoder test to check for problems with the carriage motor, encoder strip, and electronics module.
• Remove dirt from the slider rod and chassis beam. Apply oil (Anderol 4068, HP part number: 6040-0858) to the carriage bushings.
• 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.
• Ensure that the encoder strip is not inverted, damaged or absent.
• Reconnect or replace the trailing cable t page 8-8.
• Replace the carriage assembly t page 8-37.
