Main PCB block diagram
The main PCB (MPCB) consists mainly of the CPU IC5 and motor drive circuit.
The CPU IC5 detects the condition of the switches and sensors and controls the motors and solenoids by serially
communicating with the copier. The feedshift solenoid (FSSOL) operates with the control signals from the copier.
