CHAPTER 10 CASSETTE FEEDER

B. Jam Sensing
1. Pick-up delay Jam
During the cassette feeding sequence, once the pick-up solenoid (SL301) is ON, if
the paper does not arrive at the pick-up sensor (PS303) within 3 seconds, the feeding
operation is retried. Once again, if the pick-up sensor does not come ON in the 3 sec-
onds following the activation of the pick-up solenoid, the unit determines that a delay
jam has occurred.
