C.Job Offset
(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 stapling.
At power-on, the finisher controller PCB drives the aligning plate (front)
motor (FFJM) and the aligning plate (rear) motor (FRJM) to return the
two aligning plates to their home positions.

(2)Processing Tray Paper Stacking Operation
A sheet coming between the delivery rollers is fed onto the processing
tray. Then the paddle taps on the sheet surface twice (once for the
second and subsequent sheets) to locate the sheet against the
processing tray stopper.

(3)Offset Operation
Each sheet is pulled forward or backward using the aligning plate (front)
and the aligning plate (rear).
The offset operation is performed each time a sheet is pulled onto the
processing tray.
