CHAPTER 5 PICK-UP/FEEDING SYSTEM

2. Set-Back Operation

1) After copying on the first side, the first copy paper is sent from the delivery assembly
to the lower feeding assembly. At that time, the leading edge of the copy paper is
made to arch by the set-back roller 1.

2) The lower feeder flapper lowers and, at the same time, the set-back rollers 1 and 2
rotate to move the copy paper forward so that the paper leaves the lower feeder inlet
paper sensor (PS12)

Reference:
If a large number of copies are made, its leading edge would reach the lower
feeding assembly outlet roller assembly when its trailing edge is moved away from
PS12; this problem is solved by changing the path of the paper by lowering the
lower feeder flapper.
