1. [Read Position Sensor (PS302)]
When a document is brought to the read position, the shelter plate is lifted, the photo transistor becomes ON, and the input
signal of IC301-20 pin (Operation) becomes a low level. When there is no document at the read position, the shelter plate
closes the sensor light, the photo transistor becomes OFF, and the input signal of IC301-20 pin (Operation) becomes a high
level. (When checking this sensor, the IC301-9 pin becomes a low level.)

2. [Document Sensor (PS301)]
When a document is set, the shelter plate closes the sensor light, the photo transistor becomes OFF, and the input signal of
IC301-20 pin (Operation) becomes a high level. When there is no document, the shelter plate is lifted, the photo transistor
becomes ON, and the input signal of IC301-20 pin (Operation) becomes a low level. (When checking this sensor, the IC301-4
pin becomes a low level.)
