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.
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 “Error
messages appearing on the LCD “ below.
To display detailed error information, use maintenance-mode function code 82 described in the “List of
Maintenance-Mode Functions” section of the “Main Chapter” (that is, make the equipment enter the
maintenance mode and then press the “8” and “2” keys). Following the MACHINE ERROR, one of the
error codes listed in “Error codes shown in the "MACHINE ERROR X X" message” will appear on the LCD.
