Plain + Error + Ready: RS;232;C data overflow. Data byte was not read before another was entered into the UART. Possible causes are:

D Incorrect configuration in communications speed/protocol. D Incorrect communications cable. D Error in host computer. D Faulty electronics module.

Plain + Error + Roll: Processor fault.

D Turn the plotter off, and then on again to see if the problem disappears.

D If the problem remains, consult recent service notes for a possible solution. D If no service note deals with this error, report the problem to your

HP Response Center. Note conditions and actions before error occurred. Include setup sheet and service configuration plot in report.

Load Media + Error + Film: Servo error in the Y;axis (carriage axis). Try one or more of the following:

D Clear any binding due to a media jam.

D Turn the plotter 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. D Replace the carriage.

Load Media + Error + Normal: Error in X;axis calibration.

D Is X;axis 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 drive;roller gear; if alignment is incorrect, the problem may be in the carriage.

Error + Film + Ready: Failure of RS;232;C loopback test.

Ensure the loopback connector is the appropriate one.

If the problem remains, replace the electronics module.
