Error Indication; Machine Errors; 1 ] Error Messages On The Lcd - Brother MFC9700 Service Manual

1. ERROR INDICATION

To help the user or the service personnel promptly locate the cause of a problem (if any), the
machine incorporates the self-diagnostic functions which display error messages for machine errors
and communications errors. (Note that machines w/o fax do not support error messages for
communications errors.)
For the communications errors, the machine also prints out the transmission verification report and
the communications list.
1.1

Machine Errors

If a machine error occurs, the machine emits an audible alarm (continuous beeping) for
approximately 4 seconds and shows the error message on the LCD. For the error messages, see
[ 1 ] below.
To display detailed error information, use the maintenance-mode function code 82 described in
Chapter V, Section 3.12 (that is, make the machine enter the maintenance mode and then press
the 8 and 2 keys). Following the MACHINE ERROR, one of the error codes listed in [ 2 ] will appear
on the LCD.
