Motor and fan functions
NOTE: The DC controller monitors the feed motor, drum motor, and fuser motor to determine motor
failure. The DC controller does not determine if the intermediate switchback motor, the switchback
motor, the delivery motor, or the duplex re-pickup motor has failed, therefore a jam occurs when one of
these motors fails.
NOTE: The DC controller determines a fan failure and notifies the formatter when the fan locks for a
specified period from when the fan starts up.
