1. ERROR INDICATION To help the user or the service personnel promptly locate the cause of a problem (if any), the machine incorporates the self-diagnostic functions which display error messages for machine errors and communications errors. (Note that machines w/o fax do not support error messages for communications errors.) For the communications errors, the machine also prints out the transmission verification report and the communications list. 1.1 Machine Errors If an machine error occurs, the machine 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 3.12 (that is, make the machine enter the maintenance mode and then press the 8 and 2 keys). Following the MACHINE ERROR, one of the error codes listed in [ 2 ] will appear on the LCD. [ 1 ] Error messages on the LCD Messages on the LCD CHANGE DRUM SOON (in the 1st row) CHECK CASSETTE CHECK CASSETTE#1 CHECK CASSETTE#2 (in the 2nd row) Reinstall cassette properly. CHECK PAPER CHECK PAPER#1 CHECK PAPER#2 RELOAD PAPER (These messages appear alternately.) Probable Cause The service life of the drum unit will expire soon. This message appears for one minute. (You can turn this message indication on or off by the maintenance-mode function code 10, WSW31, selector 8. Refer to Chapter V, Section 3.5.) The cassette sensor detects that no paper cassette is loaded. (For those models available with a 2nd paper cassette, the "CHECK CASSETTE#1" or "CHECK CASSETTE#2" will appear if the cassette sensor or the 2nd cassette sensor does not detect paper cassette, respectively. If both sensors detect no cassette, the "CHECK CASSETTE" will appear.) Even after paper pick-up operation, the manual insertion sensor does not detect paper. (For those models available with a 2nd paper cassette, the "CHECK PAPER#1" or "CHECK PAPER#2" will appear if the manual insertion sensor or 2nd registration sensor does not detect paper, respectively. If both sensors detect no paper, the "CHECK PAPER" will appear.) (in the 1st row) CHECK SCAN LOCK (in the 2nd row) Release scanner lock lever, then press STOP KEY. The output of the CCD HP sensor does not change because: 1) The CCD lock is placed in the lock (backward) position, 2) The CCD HP sensor is defective, or 3) The CCD motor is defective. *On machines equipped with a single-row LCD, these messages appear alternately.
