15. SERVICE CALL CONDITIONS
15.1 SUMMARY
There are 3 levels of service call conditions.
Level
To prevent the machine from being damaged, the SC can only be
A reset by a service representative (see the note below).
The copier cannot be operated at all.
The SC can be reset by turning the main switch off and on if the SC
B
was caused by a sensor error.
The copier can be operated as usual except for the unit related to
C
the service call.
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) To reset a Level A SC, enter SP 5-810 (SC code reset) and select
"1". Then hold down the Photo mode key and the
same time for at least 3 seconds (this does not require the main
switch to be turned off and on).
4) When a Level A or B SC occurs while in an SP mode, the display
will not indicate the SC number. If this occurs, check the SC
number after leaving the SP mode.
