Check procedures/corrective measures
Check the connection of connectors CN3
on the copier main PCB and CN5 on the
desk main PCB, and the continuity across
the connector terminals. Remedy or
replace if necessary.
Replace the copier main PCB and check
for correct operation.
Replace the desk main PCB and check for
correct operation.
Replace the desk upper lift motor.
Check for continuity across the coil. If
none, replace the desk upper lift motor.
Reinsert the connector. Also check for
continuity within the connector cable. If
none, repair or replace the cable.
Check if CN1-5 on the desk main PCB
goes low when the desk upper lift limit
switch is turned off. If not, replace the desk
upper lift limit switch.
Reinsert the connector. Also check for
continuity within the connector cable. If
none, repair or replace the cable.

Communication problem
An error code from the paper feed desk
is detected eight times in succession.
No communication: there is no reply
after 3 retries.
Abnormal communication: a
communication error (parity or
checksum error) is detected five times
in succession.
Desk upper lift motor problem
When the upper drawer of the paper
feed desk is inserted, the desk upper lift
limit switch does not turn on within 6 s
of the desk upper lift motor turning on
and the desk upper lift limit switch does
not turn on by turning off the desk
upper lift motor for 200 ms and retrying
twice.
During copying, the desk upper lift limit
switch does not turn on within 200 ms
of the desk upper lift motor turning on.
Remarks
1-3-2 Self-diagnosis
(1) Self-diagnostic function
When a problem is detected in the paper feed desk, copying is disabled and the problem displayed on the operation unit of
the copier as a code consisting of “C” followed by a number between 0420 and 2600, indicating the nature of the problem.
After removing the problem, the self-diagnostic function can be reset by turning the desk safety switch off and back on.
