Interpret control panel messages
Control panel message types
The control panel messages indicate the current product status or situations that might require action.
Alert and warning messages appear temporarily and might require you to acknowledge the message
by pressing the
OK button to resume or by pressing the Cancel button to cancel the job. With
certain warnings, the job might not complete or the print quality might be affected. If the alert or
warning message is related to printing and the auto-continue feature is on, the product will attempt to
resume the printing job after the warning has appeared for 10 seconds without acknowledgement.
Critical error messages can indicate some kind of failure. Turning off and then turning on the power
might fix the problem. If a critical error persists, the product might require service.
