6.12.7. Read Position Sensor
This sensor detects the front edge of the document.
When the front edge of the document is detected, the shelter plate closes the sensor light.
So the photo-transistor turns off and the input signal of IC300-AB24pin becomes high level.
When the front edge of the document is not detected, the shelter plate lets the sensor light pass.
So the photo-transistor turns on and the input signal of IC300-AB24pin becomes low level.
This sensor LED is controlled by IC300-M26pin.
