Control-panel messages
The majority of the control-panel messages are intended to guide the user through typical operation.
The control-panel messages indicate the status of the current operation, and include a page count on
the second line of the display, if appropriate. When the product is receiving print data or scanning
commands, control-panel messages indicate this status. In addition, alert messages, warning
messages, and critical error messages indicate situations that might require some action.
Solve control-panel display problems
CAUTION: Static electricity can cause unexpected black lines or dots to appear on the product control-
panel display. Do not touch the product control-panel display if there is a chance that you have collected
a static electric charge (for example, by walking on carpet in a low-humidity environment).
Unexpected lines or dots might appear on the product control-panel display, or the display might become
blank if the product is exposed to an electric or magnetic field. To resolve this problem, perform the
following procedure:
1. Turn the product off.
2. Remove the product from the electric or magnetic field.
3. Turn the product on again.
Alert and warning messages
Alert and warning messages appear temporarily and might require the user to acknowledge the
message by pressing OK to resume or by pressing Cancel 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.
