Error Log

Viewing the Error Log

The error log provides a history of printer errors. The error log
contains the 12 most recent errors that have occurred on the printer.
The most recent error displays in position 1 and the oldest error
displays in position 12 (if 12 errors have occurred). If an error occurs
after the log is full, the oldest error is discarded. Identical errors in
consecutive positions in the log are entered. All 2xx and 9xx error
messages are stored in the error log.
