I. BASIC CONSTRUCTION
A. Outline of the Electrical Circuitry
The machine's electrical mechanisms are controlled by the DADF controller PCB. A
microprocessor (CPU) is used on the DADF controller PCB, and the microprocessor reads the input
signals from the sensors and the copier and generates signals used to drive DC loads (motors,
solenoids) at such times as programmed in advance.
