6.1 SERVICE CALL CONDITIONS
6.1.1 SUMMARY
There are 4 levels of service call conditions.
Level Definition Reset Procedure
A To prevent the machine from being damaged,
the SC can only be reset by a service
representative (see the note below). The
copier cannot be operated at all.
Enter SP mode, then turn the
main power switch off and
on.
B The SC can be reset by turning the main
power switch off and on if the SC was caused
by incorrect sensor detection.
Turn the operation switch or
main power switch off and
on.
A level B’ SC can only be
reset by turning the main
power switch off and on.
C The copier can be operated as usual except
for the unit related to the service call.
Turn the operation switch off
and on.
D The SC history is updated. The machine can
be operated as usual.
The SC will not be displayed.
All that happens is that the
SC history is updated.
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.
