6.13.6. 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 IC604-111pin 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 IC604-111pin becomes low level.
6.13.7. REGISTRATION & MANUAL PAPER SENSOR
This sensor detects whether the recording paper is at the sensor position.
When the recording paper is detected, the shelter plate lets the sensor light pass.
So the photo-transistor turns on, and input signal of IC604-112pin becomes low level.
When the recording paper is not detected, the shelter plate closes the sensor light.
So the photo-transistor turns off, and input signal of IC604-112pin becomes high level.
Photo-transistor Signal (IC604-111pin)
A document exits OFF High level
No document ON Low level
Photo-transistor Signal (IC604-112pin)
Paper exits ON Low level
No paper OFF High level
