4. OVERALL MACHINE CONTROL
The main DC power supply board provides +24 volts (VA) and +5 volts (VC)
to the sorter main board. +24 volts powers the roller drive motor, and +5 volts
powers all sensors and switches. Also, +24 volts is changed to +12 volts by
the regulator IC, which powers the bin drive motor.
The copier main board controls the drive and checks the status of the sorter
via the sorter main board and the interface board. The interface board sends
the scan signals to the data selected IC on the main board according to the
signal from the copier main board. After receiving the scan signals, the data
select IC outputs the status of the sensor and switches as the scan output
signal.
The interface board also sends the sorter drive signal to the drive IC on the
sorter main board according to the signal from the copier main board. After
receiving the drive signal, the drive IC turns on the appropriate motors.
