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.

Messages on the LCD
Probable Cause
CHANGE DRUM SOON
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.)
CHECK CASSETTE
CHECK CASSETTE#1
CHECK CASSETTE#2
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.)
CHECK PAPER
CHECK PAPER#1
CHECK PAPER#2
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.)
CHECK SCAN LOCK
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.
