CHAPTER 7 PICK-UP/FEEDING SYSTEM
f. Pick-Up Retry
If the pick-up sensor detects a delay because of wear on the pick-up roller or the like, the
machine initiates a pick-up retry. If a delay is detected once again despite the retry, the machine
will indicate the Jam message on the control panel, starting feeding control using the pull-out
roller.
