4.1 SERVICE CALL CONDITIONS

4.1.1 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 service
A
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 caused
B 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 can
D be operated as usual.
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.
4) Some of these SC codes contain more than one level (SC303-1,
SC303-2, SC303-3, etc.); however, some SCs may display a "-1" even if
there is no second or third level (-2, -3).
!
CAUTION
Never turn off the main power switch when the power LED is lit or flashing.
To avoid damaging the hard disk or memory, press the operation power
switch on the operation panel to turn the power off, wait for the power LED
to go off, then turn the main power switch off.
