1.7 OVERALL ELECTRICAL CIRCUIT
The DF CPU controls the DF feed motor, DF feed clutch, DF pick-up solenoid, and
stamp solenoid. The DF CPU also monitors all sensors and provides updated
status when prompted at regular intervals by the mainframe, which may then take
action based on this information. The DF/mainframe connection is checked
automatically immediately after the mainframe is powered on.
