NOTE:
1) If the problem is related to electrical circuit boards, first disconnect
then reconnect the connectors before replacing the PCBs.
2) If the problem is related to motor lock, first check the mechanical
load before replacing motors or sensors.
3) To reset a Level A SC, enter SP mode then turn the main switch
off and on.
4) When a Level A or B SC condition occurs while in SP mode, the
display does not indicate the SC number. You can recognize that
there is an SC condition because no key input is possible. If this
occurs, check the SC number by turning the main switch off and
on and make some test copies.
