CHAPTER 7 PICK-UP/FEEDING SYSTEM
7-18
3.
Registration sensor stationary jam (for cassette pick-up)
A registration sensor (PS302) stationary jam is only detected when continuous multi-
ple sheet pick-up takes place.
At the time of the following sheet pick-up, the jam detection starts within approx. 3.0
seconds after the pick-up sensor (PS303) has turned ON (the following sheet leading
edge is in a position of approx. 10mm in front of the vertical path roller).
If approx. 2.5 seconds has passed, but the trailing edge of the preceding sheet has
not left the registration sensor (PS302), the registration sensor judges a delay jam has
occurred.
