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 re-
port and the communications list.

Equipment Errors

If an equipment error occurs, the facsimile equipment emits an audible alarm (continuous beep-
ing) 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 XX" includes an
error code which indicates the detailed error causes listed in [ 2 ]. To display an error code for
the other latest error message, make the equipment enter the maintenance mode and press
8 and 2 keys (for details, refer to Chapter V, Section 3.9).
