AR-FN7/PN1 OPERATIONAL DESCRIPTION 4-1
[4] OPERATIONAL DESCRIPTION
1. Basic Operations
A. Specifications
The finisher serves to deliver sheets coming from its host machine. The
mode of delivery may be non-sort stack, job offset*, or staple delivery.
The saddle unit built into the finisher is used to fold a stack of sheets
coming from the finisher unit in half for delivery.
All these operations are controlled by various commands sent by the
host machine in addition to the commands from the finisher controller
PCB.
The puncher unit (option) is designed for installation to the pickup
assembly of the finisher, and is used to punch holes in sheets coming
from the host machine.
The above operations are controlled with various commands from the
finisher controller PCB as well as the commands from the punch
controller PCB.
Fig.F02-101-01
NOTE:The position of delivery is shifted to the front/rear for each stack to
assist sorting.
B. Outline of the Electrical Circuitry
The sequence of finisher operations is controlled by the finisher
controller PCB. The finisher controller PCB is a 16-bit microprocessor
(CPU),and isalso used for communication with the host machine (serial).
The finisher controller PCB drive motors and other loads in response to
the various commands from the host machine. It also communicates
such data as on the states of various sensors and switches to the host
machine by way of the serial communication line.
The ICs mounted to the finisher controller PCB have the following
functions:
•IC13 (CPU)
Controls sequence of operations.
•IC12 (EEP-ROM)
Backs up adjustment settings.
•IC6 (EP-ROM)
Stores sequence programs.
•IC11 (communication IC)
Communicates with the host machine.
•IC1 (regulator IC)
Generates 5 V.

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).
Ifa punch unit(option) is installed, the sheets are punchedanddelivered
to the delivery tray.
Sheets may be delivered in either of five ways (including one for the
puncher unit):
Fig.F02-201-01
(1)Normal Delivery
a.Simple Stacking
The machine pulls in the sheet once to the processing tray and then
delivers it to the delivery tray.
Fig.F02-201-02
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
stack. When the number ofsheetsstacked onthe processing
tray reaches a specified value, the sheets are delivered in a form of a
stack. Even if the specified value is not reached, stacked sheets are
temporarily delivered when 10 sheets of large-size paper (300 mm or
longer) or 30 sheets of small-size paper (299 mm or shorter) have been
stacked. (5- and STMT-sizes: 10 sheets)
Fig.F02-201-03
c.Stapling
The machine stacks sheets coming from its host machine on the
processing tray. When the number of sheets stacked on the processing
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, staples 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.
Fig.F02-201-05
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.
F02-202-01 shows the motors that are associated with moving and
aligning sheets. These motors are controlled (rotated clockwise or
counterclockwise) by the microprocessor (CPU) on the finisher controller
PCB.
The paper path is equipped with the sensors shown in T02-202-02 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.

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 tapson 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.

Fig.F02-203-04
(4)Stack Delivery Operation
Stack delivery takes place when 10 sheets of large-size paper or 30
sheets of small-size paper (A5- and STMT-sizes: 10 sheets) have been
stacked on the processing tray with them offset in either direction.
The paddle motor rotates and the swing guide descends to hold the
paper stack between the upper and lower stack delivery rollers. The
delivery motor rotates in the forward direction 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.

3. Stapling Operation
A.Outline
Staple operation is performed to staple a specified sheets of paper using
a stapler unit.
The stapling position depends on the staple mode and paper size.
When the machine starts immediately after power-on, the finisher
controller PCB drives the slide motor (FSM) to return the stapler unit to
the home position. The stapler unit starts moving toward the front of the
stapler frame. It stops when the slide home position sensor (SHPS) on
the slide PCB located under the stapler unit. Next, the slide motor is
driven a specified number of pulses. The stapler unit moves to rear
standby position at the back of the machine, entering the standby state.
