Outline of Electric Circuits

Electric circuits of this machine are controlled by the main controller PCB2. The main 
controller PCB2 detect the input signals from sensors to output the signals that
drive DC loads such as motors, solenoids, clutches, and fans at the predetermined timings. 
The ADF driver PCB does not have a memory area; data such as the data used in the service 
mode is stored in main controller PCB2.
