7.1.1 SUMMARY
There are 4 levels of service call conditions.
Level
To prevent the machine from being
damaged, the SC can only be reset by a
A
service representative (see the note below).
The copier cannot be operated at all.
The SC can be reset by turning the main
power switch off and on if the SC was
B caused by incorrect sensor detection.
The copier can be operated as usual except
C
for the unit related to the service call.
The SC history is updated. The machine

NOTE: 1) If the problem concerns electrical circuit boards, first disconnect then
reconnect the connectors before replacing the PCBs.
2) If the problem concerns a motor lock, first check the mechanical load
before replacing motors or sensors.
3) When a Level A or B SC occurs while in an SP mode, the display does
not indicate the SC number. If this occurs, check the SC number after
leaving the SP mode. This does not apply to Level B' codes.
