6.12.5. Exit Sensor
This sensor detects whether a recording paper exits or not.
When there is a recording paper at the position of the sensor, the input signal of IC300-AF23pin becomes low level.
When there is no recording paper at the position of the sensor, the input signal of IC300-AF23pin becomes high level.
6.12.6. Document Sensor
This sensor detects whether a document is set in ADF or not.
When a document is 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 not 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.
This sensor LED is controlled by IC300-M26pin.
