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 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 3.12).
