2 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
