Backup memory read/write problem
(main PCB)
• Read and write data does not match.
Backup memory data problem (main
PCB)
• Data in the specified area of the
backup memory does not match the
specified values.
Backup memory read/write problem
(engine PCB)
• Read and write data does not match.
Backup memory data problem (en-
gine PCB)
• Data in the specified area of the
backup memory does not match the
specified values.
Accounting count problem
• When the power is turned on, the to-
tal count and the scan count are ab-
normal both on the main PCB and the
engine PCB.
Machine number mismatch
• When the power is turned on, the ma-
chine number does not match be-
tween the main PCB and the engine
PCB.
Communication problem between
the main PCB and engine board PCB
• When the power is turned on, the ma-
chine does not detect the low level of
SBSY and the high level of SDIR for
three seconds.
Optional DP communication problem
• Communication fails five times suc-
cessively.

EEPROM.
Poor contact in
the connector ter-
minals.
Defective main
PCB or engine
PCB.
DP installed incor-
rectly.
Defective main
PCB or DP driver
PCB.
Replace the main PCB and check for cor-
rect operation.
Turn safety switch off and back on and run
maintenance item U020 to set the contents
of the backup memory data again.
If the C011 is displayed after re-setting the
backup memory contents, replace the
backup RAM or main PCB.
Replace the engine PCB and check for
correct operation.
Turn safety switch off and back on and run
maintenance item U020 to set the contents
of the backup memory data again.
If the C016 is displayed after re-setting the
backup memory contents, replace the
backup RAM or engine PCB.
Replace the main PCB or engine PCB and
check for correct operation.
Install the correct EEPROM. If it does not
solve the problem, contact the Service Ad-
ministrative Division.
Contact the Service Administrative Divi-
sion.
Check the connection of connectors YC6
on the main PCB and YC1 on the engine
PCB, and the continuity across the connec-
tor terminals. Repair or replace if neces-
sary.
Replace the main PCB or engine PCB and
check for correct operation.
Check the installation state of the DP and
adjust it if it is not properly installed.
Replace the main PCB or DP driver PCB
and check for correct operation.
1-5-2 Self-diagnosis
(1) Self-diagnostic function
This unit is equipped with a self-diagnostic function. When a problem is detected, copying is disabled. "C" and a number
between 0100 and 7810 altenates, indicating the nature of the problem.
After removing the problem, the self-diagnostic function can be reset by opening and closing the front cover to turn safety
switch off and on or power switch turns off and on.
“A” is displayed on the operation panel.
