6.13.24. Optional OPF Cover Switch
This switch detects whether the OPF cover is open or closed.
When the cover is closed, the input signal of IC300-H34pin becomes low level.
When the cover is open, the input signal of IC300-H34pin becomes high level.
6.13.25. Optional ADU Jam Sensor
This sensor detects whether the paper is at the ADU sensor position.
When the recording paper is detected, the shelter plate lets the sensor light pass.
So the photo-transistor turns on and the input signal of IC300-K34pin becomes low level.
When the recording paper is not detected, the shelter plate closes the sensor light.
So the photo-transistor turns off and the input signal of IC300-K34pin becomes high level.
6.13.26. Optional ADU Cover Switch
This switch is turned ON and OFF by opening and closing ADU cover to provide power supply to ADU driving motor IC.
