3 Control-panel message types
The control-panel messages and error code entries indicate the current product status or situations that
might require action.
NOTE: The Error Information Report provides more detailed information on the error and does not
appear on the control-panel display.
To print and view the Error Information Report perform the following:
● Enter Service Mode.
● Select Information > Report > Error Information (Error Info.) .
● Select OK.
● Error Information Report will be printed out.
A control-panel message displays temporarily and might require the user to acknowledge the message by
touching the OK button to resume printing or by touching the Stop button to cancel the job. With certain
messages, the job might not finish printing or the print quality might be affected.
For some messages, restarting the product might fix the problem. If a critical error persists, the product
might require service.

Error codes
Error codes and control-panel messages display on the printer control panel to indicate the current printer
status or situations that might require action. Error codes are numerical, or alphanumerical, and have a set
structure with six characters (example: A1-xxxx).
● The first two characters are numeric and represent the system component that is causing the error. For
example, in error code A1-1211, A1 = Motor for these printers.
● The remaining four digits further define the error.
The CPMD is a comprehensive list of error codes, diagnostic and troubleshooting steps to clear or resolve
the error, and other helpful information such as service mode pins and part numbers.
The CPMD is continually updated and republished with the latest information for the following error codes.
