SNS PC Board
Each sensor consists of an LED and phototransistor. When documents are placed on the ADF tray or are moving, a shutter in the
document sensor closes. The light path from the LED is blocked turning the phototransistor “OFF”, and the output voltage from the
sensor becomes a “High” level. With no document on the ADF tray, the shutter opens the light path, and output from the sensor is
kept at a “Low” level. Operation of the RP Sensor is opposite to the ADF Sensor. When the leading edge of the document reaches
the RP Sensor, the shutter opens and the output voltage becomes a “Low” level. Then, the shutter closes and the output becomes
a “High” level when the lagging edge of the document clears the RP Sensor. The Tx Door Sensor operation is the same as the ADF
Sensor, the output from the sensor is kept at a “Low” level when the door is closed and becomes a “High” level when the Tx Door
is opened.
