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 all-in-one is receiving fax data, 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.
