Document Sensor
This sensor detects whether a document is set in ADF or not.
When a document is set in ADF, the shelter plate closes the sensor light.
So, the photo-transistor turns off, and input signal of IC300-AC26pin becomes high level.
When a document is not set in ADF, the shelter plate lets the sensor light pass.
So, the photo-transistor turns on, and input signal of IC300-AC26pin becomes low level.
When a document is set in ADF, the shelter plate closes the sensor light.
So, the photo-transistor turns off, and input signal of IC300-AC26pin becomes high level.
When a document is not set in ADF, the shelter plate lets the sensor light pass.
So, the photo-transistor turns on, and input signal of IC300-AC26pin becomes low level.

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 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 input signal of IC300-AB24pin becomes low level.
When the front edge of the document is detected, the shelter plate closes the sensor light.
So, the photo-transistor turns off, and 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.
