CHAPTER 2 OUTLINE OF OPERATION
2.3  Job Offset
2.3.1  Outline
"Job offset" refers to the operation by which the machine delivers a set of sheets with
them pulled forward or backward for sorting.
Switching between the forward and backward directions is made using an aligning plate
(front) and an aligning plate (rear).
The sheet coming between the delivery rollers is fed onto the processing tray and then fed
toward the stopper by the paddle.
A swing guide is at the up position while a sheet is being pulled onto the processing tray
or during alignment.  It is at the down position during stack feeding, stack delivery, or sta-
pling.
At power-on, the finisher controller PCB drives the aligning plate (front) motor (M4) and
the aligning plate (rear) motor (M5) to return the two aligning plates to their home posi-
tions.
