Error Indication - Brother MFC9100C Service Manual

1. ERROR INDICATION

To help the user or the service personnel promptly locate the cause of a problem (if any), the
facsimile equipment incorporates the self-diagnostic functions which display error messages for
equipment errors and communications errors.
For the communications errors, the equipment also prints out the transmission verification report
and the communications list.
1.1 Equipment Errors
If an equipment error occurs, the facsimile equipment 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 3.14 (that is, make the equipment enter the maintenance mode and then press
the 8 and 2 keys). Following the MACHINE ERR, one of the error codes listed in [ 2 ] will appear
on the LCD.
