C600 10 SM

2.4 OVERALL ELECTRICAL CIRCUIT

The C235 directly controls the DF pick-up solenoid, stamp solenoid, and DF feed
clutch through the DF drive board. The sensor signals are directly sent to the
copier through the DF drive board. The DF drive board has a driver for the DF
transport motor and the drive signals are sent from the C235.
When the DF connector is connected to the main processing unit, the DF
connection signal to the C235 goes to 5 V. Then the C235 detects that the DF is
connected.
