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, if
appropriate. When the product 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.

Find and remove the jam by using the instructions on the following pages. If the location of the jam is
not obvious, first look inside the product.
