2.7 OVERALL ELECTRICAL CIRCUIT
Copier IOCSS
Board
The DF pick-up solenoid, junction gate solenoid, stamper solenoid, and DF
feed clutch are directly controlled by the copier through the DF drive board.
The sensor signals are sent directly to the copier through the DF drive board.
The DF drive board has a driver for the DF feed and transport motors and
their drive signals are sent from the copier.
When the DF connector is connected to the copier IOCSS board, the DF
connection signal to the copier will go to 5 V. Then, the copier will detect that
the ARDF is connected.
