The DF CPU controls the transport motor, DF feed motor, DF feed clutch, junction
gate solenoid, stamp solenoid, and pick-up solenoid. The DF CPU also monitors all
DF sensors and provides updated status information when prompted at regular
intervals by the mainframe, which may then take action based on this information.
The DF–mainframe connection is checked automatically just after power is
supplied to the mainframe.
