MX-FNX2/AR-PN1/MX-RBX1 OPERATIONAL DESCRIPTION 5 – 6
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 pro-
cessing 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 posi-
tion during stack feeding, stack delivery, or stapling.
At power-on, the finisher controller PCB drives the aligning motor
(front) (FFJM) and the aligning motor (rear) (FRJM) to return the
two aligning plates to their home positions.

cessing tray. Then, the paddle taps on the sheet surface 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.

Offsetting in the forward direction
Offsetting in the backward direction
(4) Stack Delivery Operation
Stack delivery takes place when 1 sheet of large-size paper or 25
sheets of small-size paper have been stacked on the processing
tray with them offset in either direction.
The paddle motor (FPM) rotates and the swing guide descends to
hold the paper stack between the upper and lower stack delivery
rollers. The stack delivery motor (FAM) rotates in the forward direc-
tion to rotate the delivery rollers, feeding the paper stack in the
delivery direction. The delivery belt home position sensor is turned
OFF. The delivery motor is driven a specified number of pulses,
causing the swing guide to ascend. Next, the paper delivery motor
is driven. Next, the delivery motor is driven to deliver the paper
stack with the nails of the delivery belt that rotates in sync with the
stack delivery rollers.
