âºíuÇ´ Service Manual
[1] PRODUCT OUTLINE
1. Product outline
This unit is installed to the following machines to perform the after-process of output paper from a copier, or a fax machine. The output paper
is passed to the saddle finisher by the interface unit (MX-RBX1). Each sheet is discharged one by one by the offset function.
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.)
The finisher requires staple cartridge as a consumable part. (Staple cartridge (About 5000 staples x 3) AR-SC2)
2. Configuration
1) When installing this unit, the paper feed desk (MX-DEX1/DEX2) and the interface unit (MX-RBX1) must be installed together.
2) This unit cannot be installed with the finisher (MX-FNX1) simultaneously.

MX-FNX2/AR-PN1/MX-RBX1 OPERATIONAL DESCRIPTION 5 – 1
âºíuÇ´ Service Manual
[5] 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.
The punch unit (option) is designed for installation to the pickup
assembly of the finisher, and is used to punch holes in sheets com-
ing 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 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 microproces-
sor (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: Stores sequence programs.
• IC11 (expansion port): I/O port
The flow of signals between finisher and options controller is shown
as below.

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):
(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.
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.

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.
(2) Processing Tray Paper Stacking Operation
A sheet coming between the delivery rollers is fed onto the pro-
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.

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 staple shift motor (FSM) to return the sta-
pler unit to the home position. The stapler unit starts moving toward
the front of the stapler frame. It stops when the staple shift home
position sensor (FSTHPD) on the slide PCB located under the sta-
pler unit. Next, the staple shift motor (FSM) 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.
B. Stapling Operation
When stacking and alignment of paper on the processing tray are
complete, the finisher controller PCB drives the paddle motor
(FPM) in the reverse direction and lowers the swing guide. When
the swing guide descends, the paper stack is sandwiched between
the upper and lower stack delivery rollers.
The finisher control PCB shifts the stapler according to the speci-
fied staple position to perform stapling. (Only for B5-R, 1-position
bottom stapling is made at the rear side of 2-posiiton stapling.)
When the stapler shifts toward you, the process tray stopper is put
down to the lower side.

C. Delivery Operation after Stapling
When stapling is complete, the finisher controller PCB drives the
stack delivery motor (FAM) in the forward direction to feed the
paper stack (sandwiched between the stack delivery rollers) in the
delivery direction. The delivery belt home position sensor (FOB-
HPD) is turned OFF. The stack delivery motor (FAM) is driven a
specified number of pulses, causing the swing guide to ascend. At
the same time, the staple shift motor (FSM) is driven to return the
stapler back to the standby position, followed by driving of the stack
delivery motor (FAM). Then, the paper stack is delivered with the
nails of the delivery belt that rotates in sync with the stack delivery
rollers.
D. Stapler Unit
The staple motor (FFSM) is used to perform stapling operation.
This motor rotates the cam one turn for stapling. The home position
of this cam is detected by the staple drive home position sensor
(FSHPD).
The staple motor (FFSM) is rotated in the forward or reverse direc-
tion under the control of the macro computer (IC13) on the finisher
controller PCB.
When the staple drive home position sensor (FSHPD) is OFF, the
finisher controller PCB rotates the staple motor (FFSM) in the for-
ward direction until the sensor turns ON, allowing the staple cam to
the original position.
The staple empty sensor (FSD) is used to detect presence/
absence of a staple cartridge in the machine. The self prime sensor
(FSPD) is used to detect presence/absence of staples in the car-
tridge.
The finisher controller circuit does not drive the staple motor
(FFSM) unless the staple safety switch (FSSSW) is ON (the swing
guide is close). This assures safety in case where you happen to
put your finger in the stapler.

(1) Stapler Movement Controller
The stapler unit is moved by the staple shift motor (FSM). Its home
position is detected by the staple shift home position sensor
(FSTHPD). The stapler waits at the back irrespective of the staple
mode and paper size. After paper has been stacked on the pro-
cessing tray, the stapler is moved to the specified stapling position
in response to the stapling command from the host machine.
The figure below shows the standby position of the stapler and the
stapling position depending on the staple mode.
1) Front 1-point stapling
The stapler waits at the back. The stapler moves to and
returns from the stapling position for each stapling operation.
2) Rear 1-point stapling
The stapler waits at the back. The stapling position is the same
as the standby position. (Except B5R)
3) Middle 2-point stapling
The stapler waits at the back. The stapler moves to and
returns from the stapling position for each stapling operation.
The stapler first staples a paper stack at the rear stapling posi-
tion and then staples it at the front stapling position.
4) Middle 2-point stapling (bind mode)
The stapler waits at the back. The stapler moves to and
returns from the stapling position for each stapling operation.
The stapler first staples a paper stack at the rear stapling posi-
tion and then staples it at the front stapling position.

4. Delivery Tray Operation
A. Outline
The machine has a delivery tray in the finisher unit and a bind tray
in the saddle unit.
The bind tray in the saddle unit is of the fixed type and all the folded
paper stacks are delivered to this tray. This tray has a bind tray
sensor (FFED) to detect presence/absence of paper.
The delivery tray in the finisher unit is moved up and down using a
lift motor (FLM).
The finisher has a tray paper sensor (FBED) to detect presence/
absence of paper on the stack tray.
The home position sensor of the delivery tray is detected by the
paper surface sensor (FSLD). When paper has already been
stacked on the delivery tray, the home position is on the top surface
of the stacked paper. When paper has not yet been stacked on the
delivery tray, the home position is at the position where the edge of
the delivery tray is detected. At power-on, the finisher controller
PCB drives the lift motor (FLM) to return the delivery tray to the
home position.
When the paper coming from the processing tray is stacked on the
delivery tray, the lift motor (FLM) is driven a specified number of
pulses, causing the delivery tray to descend. Clock pulses are
detected by the lift lock sensor (FLE). Then, the delivery tray
returns to the home position for the next stacking operation.
The upper limit of the delivery tray is detected by the lift upper limit
sensor (FULD). When the lift upper limit sensor (FULD) is turned
ON, the finisher controller PCB stops the lift motor (FLM) that is
ascending.
The lower limit of the delivery tray is detected by the lift lower limit
sensor (FLLD). When the lift lower limit sensor (FLLD) is turned
ON, the finisher controller PCB stops the lift motor (FLM) that is
descending.
The finisher unit has a tray middle sensor (FMLD) to detect over-
stacking of large-size or mixed paper according to the stack height.
5. Saddle Unit
A. Basic Operations
(1) Outline
The machine stitches a stack of sheets (middle 2-point), then folds
the stack in two in the finisher. These operations are controlled by
the finisher controller PCB.
The finisher controller PCB is controlled by the commands from the
host machine.
B. Feed/Drive System
(1) Outline
This machine stitches the paper stack coming from the finisher,
folds it, and delivers it to the bind tray in the saddle unit in response
to the commands from the host machine.
That is, the machine performs the following operations:
a. Paper feed-in
b. Stitching
c. Stack feed
d. Folding/delivery
a. Paper feed-in
After being aligned on the processing tray, a stack of sheets is
sandwiched between the stack delivery rollers. As the stack deliv-
ery rollers rotate, the stack is fed toward the saddle unit.
