These SCs can be cleared by turning

Turn the main power switch off and on.
NOTE:
1) If a problem involves circuit boards: Before deciding to replace a circuit
board, first see if you can solve the problem by disconnecting and then
reconnecting all connectors.
2) If a problem involves a motor lock: Check the mechanical load first,
before deciding whether to replace motors or sensors.
3) If working on a fax-equipped machine, keep in mind that switching
power off and back on may in some cases cause loss of data stored in
SAF memory.
