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 and the problem dis-
played as a code consisting of C followed by a number between 0060 and 9080, indicating the nature of the problem. A
message is also displayed requesting the user to call for service.
After removing the problem, the self-diagnostic function can be reset by turning front cover/feed cover switch off and back
on.

List of system errors
When an unexpected error is detected for some reason, a system error will be indicated. (When 0800 error is detected,
JAM05 is indicated.) After a system error is indicated, the error can be cleared by turning the power switch off and then on.
If the error is detected continuously, however, perform the operation shown in Table 1-5-1. If a system error occurs fre-
quently, a fault may have occurred. Check the details of the C call to take proper measures.
