(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, 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 safety switches off and back on.
List of system errors
When an unexpected error is detected for some reason, a system error will be indicated. After a system error is indicated,
the error can be cleared by turning the main power switch off and then on. If the error is detected continuously, however,
perform the operation shown in Table 1-4-1. If a system error occurs frequently, a fault may have occurred. Check the
details of the C call to take proper measures.
Table 1-4-1
In addition, it is a system error if the following error code is displayed. When an error has occurred, clear the error by
turning the main power switch off then on.
CF1XX, CF2XX, CF3XX, CF4XX, CF5XX, CF6XX, CF7XX, CFAXX, CFBXX, 0xFBXX
Partial operation control
If any of the following calls for service is detected, partial operation control will be activated. After taking measures against
the cause of trouble, run maintenance item U906 to reset partial operation control.
