-Control-
The sorter has its own CPU which controls all the functions of the sorter. The sorter CPU
communicates with the copier through a parallel interface bus.
The sorter supplies 100 Vac to the transformer. The transformer changes this 100 Vac to 23
Vac and it is then supplied to the dc power supply unit. The copier also supplies +24 V to the
jam sensor through the main board.
Input signals from the sensors and the safety switches are sent to the sorter CPU directly. The
sorter CPU operates the bin solenoids and the sorter drive motor.
This sorter uses a dc motor. The motor speed is fixed by using a frequency generator (FG).
The dc motor operates at high and low paper transport speeds.
