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. As one of the error messages, “MACHINE ERROR _ _” includes an error code
which indicates the detailed error causes listed in [ 2 ].
To display an error code for the other latest error message or detailed message, make the
equipment enter the maintenance mode and press 8 and 2 keys (for details, refer to Chapter V ,
Section 3.12).

message will not appear on the LCD but some 4-digit error code listed on page VI-6 will appear instead.
