b. Re-Pick Up Operations (copying on the 2nd side)
The sheets of copy paper stacked in the lower feeding assembly after copying on the first side are
picked up by the re-pick up roller for copying on the second side.
1) When stacking is over, the set-back roller is moved clockwise, and the copy paper is moved until the
re-pick up sensor (PS11) detects the leading edge.
2) The copy paper is continuously moved; since the re-pick up flapper solenoid (SL4) turns ON a specif-
ic period of time after the re-pick-up paper sensor (PS11) turns ON, only the first sheet moves through
the re-pick-up roller and the second and subsequent sheets will be moved to on the flapper plate.
3) When the trailing edge of the first copy paper moves past the set-back roller, the set-back roller rotates
in reverse to move the copy paper to a point where the leading edge of the next copy paper will not
reach the re-pick up sensor (PS11).
