[1] INTRODUCTION
1. Product outline
This unit is installed to the following machines to perform the after-process of output paper from a printer, a copier, or a fax machine.
A. Features
1) Employment of the through-type stapler
Employment of the through-type stapler allows to make saddle stitch by one stapler.
2) 3 kinds of auto staple functions
There are 3 staple positions available. (One position in the front, one position at the back, 2 positions at the center)
3) Saddle stitch function
Up to 10 sheets of paper can be stapled at the center and folded into two and discharged.
4) Punch function (Option)
By installation of a puncher unit, paper can be punched to make holes for a binder. (Applicable for 64 - 128g/m². OHP films cannot be used.)
Applicable models AR-P350 / P450, AR-M350 / M450
DM-3500 / 3501 / 4500 / 4501, DM-3551 / 4551
2. Configuration
1. Before installation of this unit, the large-capacity tray (AR-DU3 or AR-DU4) must be installed in advance.

CHAPTER 2 OUTLINE OF OPERATION
1 Basic Operations
1.1 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 fin-
isher unit in half for delivery.
All these operations are controlled by various commands sent by the host machine in ad-
dition to the commands from the finisher controller PCB.
The puncher unit (option) is designed for installation to the pickup assembly of the fin-
isher, 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.

The position of delivery is shifted to the front/rear for each stack to assist

CHAPTER 2 OUTLINE OF OPERATION
1.2 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 is also used for combination
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.

CHAPTER 2 OUTLINE OF OPERATION
2 Feed/Drive System
2.1 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 puncher unit):

CHAPTER 2 OUTLINE OF OPERATION
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. 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)

d. Saddle Deliver y
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.

CHAPTER 2 OUTLINE OF OPERATION
2.2 Feed/Delivery
2.2.1 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.

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 stapling.
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 positions.
