2. Feed/Drive System
A. Outline
The machine performs the following in response to the commands
coming from its host machine on the sheets arriving from the host
machine for delivery: simple stacking, job offset, and stapling or
folding (in two).
If a punch unit (option) is installed, the sheets are pouched and
delivered to the delivery tray.
Sheets may be delivered in either of five ways (including one for
the punch unit):

then delivers it to the delivery tray.
The machine pulls in the sheet once to the processing tray and
then delivers it to the delivery tray.
b. Job Offset
The machine pulls the sheet once to the processing tray. It then
moves the sheet to the front or the rear using the aligning plate.
When it has deposited a specific number of sheets, it delivers them
in the form of a aligning plane. When the number of sheets stacked
on the processing tray reaches a specified value, the sheets are
delivered in a form of a stack.

c. Stapling
The machine stacks sheets coming from its host machine on the
processing tray. When the number of sheets stacked on the pro-
cessing tray reaches a specified value, the finisher staples them
delivers the stapled stack to the delivery tray.

d. Saddle Delivery
The machine deposits a stack of sheets on the processing tray, sta-
ples it (middle 2-point), and then moves it to the saddle unit. The
saddle unit folds the stack in two, and delivers it to the bind tray.

B. Feed/Delivery
(1) Outline
The machine forwards the sheets coming from its host machine to
the delivery tray, processing tray, or saddle unit according to the
type of delivery used. The sheets forwarded to the processing tray
or the saddle unit are offset, stapled, or folded.
The following table shows the motors that are associated with mov-
ing and aligning sheets. These motors are controlled (rotated clock-
wise or counterclockwise) by the microprocessor (CPU) on the
finisher controller PCB.
The paper path is equipped with the sensors shown in the following
figure used to monitor the arrival or passage of sheets.
If a sheet fails to arrive at or move past a specific sensor within a
specific period of time, the finisher controller will assume a jam, and
stops the ongoing operation and, at the same time, communicates
the presence of a jam to the host machine.

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.

The offset operation is performed each time a sheet is pulled onto
the processing tray.

(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.
