1.3 SENSORS AND FRICTION PAD
Only one actuator is used for detecting paper end and remaining paper.
The front side of the actuator is for the paper end sensor (S2) [A], and the rear side of the actuator is for
the remaining paper sensor (S3) [B].
The paper transport sensor (S1) [E] acts as a paper feed sensor.
This machine uses the friction pad method (same as the mainframe).
