Control-panel message types

Four types of control-panel messages can indicate the status of or problems with the product.

Message type


Status messages

Status messages reflect the current state of the product. They inform you of normal product operation
and require no interaction to clear them. They change as the state of the product changes. Whenever
the product is ready, not busy, and has no pending warning messages, the Ready status message
appears if the product is online.

Warning messages

Warning messages inform you of data and print errors. These messages typically alternate with the
Ready or status messages and remain until you press the


button. Some warning messages are

clearable. If the Clearable Warnings menu in the Display Settings menu is set to the Job
option, the next print job clears these messages.

Error messages

Error messages communicate that some action must be performed, such as adding paper or clearing
a jam.

Some error messages are auto-continuable. If the Continuable Events menu in the Display
menu is set to the Auto continue (10 seconds) option, the product continues normal
operation after an auto-continuable error message appears for 10 seconds.


Pressing any button during the 10-second auto-continuable error message overrides the

auto-continue feature, and the button function takes precedence. For example, pressing the Stop
button pauses printing and offers the option to cancel the print job.

Critical-error messages

Critical error messages inform you of a product failure. You can clear some of these messages by
turning the product off and then on. These messages are not affected by the Auto continue (10
setting. If a critical error persists, service is required.
