Error codes and messages
Service error codes
Service error codes are generally non-recoverable except in an intermittent condition when you can POR the
printer to temporarily recover from the error condition.
Service error codes are indicated by a three-digit error code followed by a period and additional numbers in the
format XXX.YY. In most cases, five digits are shown. Additional sub error codes display if you press and hold
and 2 when an error message is displayed. Not all error conditions have additional sub error information.
Sub error codes for 8xx and 2xx error codes
The sub error codes are helpful when troubleshooting a paper path problem, especially paper jams in the base
printer, envelope feeder, and duplex option.
To display sub error codes (where available)
When an 8xx or 2xx error displays:
1.
Press and hold and 2 to view sub error codes.
The first screen of information displays. Write down the information.
2.
Continue pressing and 2 until each screen of information is obtained.
3.
When the last screen displays, the original message displays.
Printed error codes
Additional codes are available in the Menus and Messages Guide for this option and the Service Manual for the
