7.11.2. DOCUMENT SENSOR
The Sensor detects whether or not a document is in place.
When a document is detected, the shelter plate shuts off the sensor light, the photo-transistor turns OFF, and the input signal
of IC101-19pin becomes a high level. When there is no document, the shelter plate let the sensor light pass through, the photo-
transistor turns ON, and the input signal of IC101-19pin becomes a low level.
Photo-transistor Signal (IC101-19pin)
Document Set OFF High level
No Document ON Low level
7.11.3. PAPER FEED SENSOR
The Sensor detects the front edge of the document.
When a document is detected, the switch turns ON, and the input signal of IC605-74pin becomes a low level. When there is no
document, the switch turns OFF, and the input signal of IC605-74pin becomes a high level.
Switch Signal (IC605-74pin)
Read Position ON Low level
Non Read Position OFF High level
