6.2 ROLLER DRIVE CIRCUIT
To turn on the roller drive motor, the interface board sends a drive signal to
the drive IC on the sorter main board. After receiving the drive signal, the
drive IC drops CN102-7 from +24 to 0 volt to turn on the roller drive motor.
When the paper sensor is actuated, CN102-13 drops to LOW. The interface
board outputs three scan signals to the data select IC. The status of the
sensor changes the resulting scan output signal. Using the scan output
signal, the copier main board determines the status of the sensor. For safety
reasons, the CPU limits the operation time of the roller drive motor to 5
seconds.
