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):
2
By installation of a puncher unit, paper can be punched to make holes for a binder. (Applicable for 64 – 128g/m
. OHP films cannot be
used.)
Applicable models MX-2300N/2700N/2300G/2700G
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.

[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 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.

B. Outline of the Electrical Circuitry
Service Manual
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: Stores sequence programs.
• IC11 (expansion port): I/O port
The flow of signals between finisher and options controller is shown
as below.

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):

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.

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.
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 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 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 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 motor
(front) (FFJM) and the aligning motor (rear) (FRJM) to return the
two aligning plates to their home positions.

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 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 staple shift 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 staple shift home
position sensor (FSTHPD) on the slide PCB located under the stapler 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 specified 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 (FOBHPD) 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.

The staple motor (FFSM) is rotated in the forward or reverse direction 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 forward 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 cartridge.
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.

4. Delivery Tray Operation
5. Saddle Unit
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 overstacking of large-size or mixed paper according to the stack height.
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.

Staple
Stapler (lower)

c. Stack feed
The stack feed rollers feed the paper stack to the stack folding/
delivery position where the center of the stack (stitched position) is
level with the paper pushing plate and paper folding roller's nip part.
C. Paper Feed System
(1) Outline
The paper feed system feeds a stack of sheets (coming from the
finisher) to the position where the center of the paper stack (stitching position) is aligned to the stapler's staple, allowing the next step
(stitching and folding) to be performed.
When sheets of paper have been stacked and aligned on the processing tray, the paddle motor (FPM) rotates in the reverse direction, causing the swing guide to descend. As the swing guide
descends, the paper stack is sandwiched between the upper and
lower stack delivery rollers. The stack delivery motor (FAM) rotates
in the reverse direction, feeding the paper stack toward the saddle
unit. When the leading edge of the paper stack reaches the binding
position sensor (FFPD), the finisher controller PCB drives the stack
delivery motor (FAM) a specified number of motor pulses to stop
the center of the paper stack (stitching position) at the stapler's staple position. Before the paper stack passes through the stack feed
rollers, the feed motor (FFM) is driven to rotate the stack feed roller
(lower) so that the leading edge of the paper stack is not bent.

d. Folding/delivery
The paper pushing plate pushes in the center of the paper stack to
feed it toward the paper fold rollers. Then, the paper fold rollers and
bind delivery rollers deliver the paper stack to the bind tray.
D. Stack Feed System
(1) Outline
The stack feed system feeds the stitched paper stack to the folding
position.
When stitching is complete, the feed motor (FFM) rotates, causing
the stack feed roller (upper) to descend. The paper stack is sandwiched between the stack feed rollers. Then, the bind clutch (FFC)
is turned ON to rotate the feed motor (FFM) in the forward direction, thus feeding the paper stack to the folding position. The feed
amount is equivalent to the number of pulses used to drive the feed
motor (FFM) until the paper stack reaches the folding position.

(1) Outline
The paper fold mechanism consists of a guide plate, paper fold rollers, and a paper pushing plate.
The guide plate, paper fold rollers, and paper pushing plate are
driven by the staple motor (FFSM). The drive force is transferred
with a combination of gears and cams. Motor operation is monitored by the binding lock sensor (FFE).
Until the paper stack reaches the folding position, the guide plate
covers the paper fold rollers to act as a paper path through which a
paper stack is fed to the saddle unit and to prevent a paper stack
from touching the rollers.
A binding home position sensor (FFHPD) is provided to detect the
positions of the paper fold rollers and paper pushing plate.
The paper stack folded in two by the paper fold rollers is delivered
by bind delivery rollers. The bind delivery rollers are also driven by
the staple motor (FFSM).
A bind tray sensor (FFED) is provided on the bind tray to detect
presence/absence of a paper stack; however, it is not used to
detect a jam.
(2) Paper Folding
Paper is folded using paper fold rollers and a paper pushing plate.
Almost concurrently with the start of roller rotation, the paper pushing plate starts operating to push the paper stack into the gap
between the paper fold rollers. When the paper stack is fed about
10 mm with the rotation of the paper fold rollers, the paper pushing
plate returns to the home position. Then, the paper stack is delivered to the bind tray using the paper fold rollers and bind delivery
rollers.
Half the entire surface of each paper fold roller is uncovered
excluding the central area and the area at the left and right ends.
The uncovered surface of the upper paper fold roller comes in
touch with the uncovered surface of the lower paper fold roller only
at the center and left and right ends, allowing a paper stack to be
fed without causing creases. The other half of the upper paper fold
roller that is covered comes in touch with the other half of the lower
paper fold roller that is also covered, allowing a paper stack to be
folded while being fed.

(1) Basic Operations
a. Outline
The punch unit is an option, and is designed for installation to the
pickup assembly of the finisher.
The punch unit is not equipped with a paper feeding mechanism,
and the sheets from the host machine move through the punch unit
and then the feed system of the finisher. When the trailing edge of a
sheet from the host machine reaches the punch unit, the sheet is
stopped once, and the punch shaft is rotated to punch a hole along
the trailing edge. These operations are controlled with various commands from the finisher controller PCB as well as the commands
from the punch controller PCB.
Punch drive system
Horizontal registration
drive system
Punch controller PCB
Finisher unit control system
The punch motor (FPNM), punch unit, and sensors make up the
punch slide unit, which moves to the front/rear to suit the selected
paper size. The movement to the front/rear is driven by the punch
horizontal registration motor (FPSM). The home position of the
punch slide unit is detected by the punch horizontal registration
home position sensor (FPSHPD), and the punch horizontal registration motor (FPSM) is a stepping motor.
The punch motor (FPNM) and punch horizontal registration motor
(FPSM) are controlled with various commands from the finisher
controller PCB as well as the commands from the punch controller
PCB. The waste paper occurring as the result of punching is collected in the waste paper case. The case is monitored by the
LED121 on the waste full LED PCB and PT131 on the waste full
photosensor PCB (FPDD).
(2) Punching Operation
a. Outline
The punch unit is located in the pickup assembly of the finisher,
and is used to punch holes in sheets that have been sent from the
host machine and stopped inside it. When the trailing edge of a
sheet reaches the punch unit, the inlet roller of the finisher assembly stops the sheet to punch a hole along the trailing edge of the
sheet.
The punch unit consists of a die and hole puncher (punch blade).
The hole puncher is driven by the punch motor (FPNM). It is
attached to the eccentric cam of the punch shaft, and the rotation of
the punch shaft is converted into reciprocating motion for punching
operation.
The punch motor (FPNM) is a DC motor. The home position of the
punch shaft is detected by the punch home position sensor
(FPHPD). To make sure that the punch motor (FPNM), which is a
DC motor, stops exactly at its home position, the punch motor
(FPNM) is stopped in relation to the count of the clock pulses kept
by the punch motor lock sensor (FPMCK). A single punching operation is executed by rotating the punch shaft 180° from its home
position.
As many as five light-receiving transistors (photosensor PCB) are
mounted over the inlet paper path of the punch unit; on the other
hand, as many as five LEDs (LED PCB) are mounted under the
path, together serving as five sensors. The frontmost sensor
(LED5, PT5) is used as a trailing edge sensor (FPTD) to detect the
training edge of sheets, and the remaining four (LED1 through
LED4, PT1 through PT4) are used as horizontal registration sensors (FPSD1 through FPSD4) to detect the rear position of sheets
when punching holes.

(punch shaft CCW rotation by 180°/
end of punching operation)
The hole puncher is driven by the punch motor (FPNM). The home
position for the hole puncher is detected by the punch home position sensor (FPHPD).
The punch unit comes in four types, selected to suit the country of
installation: 2-hole (Punch Unit-J1), 2- and 3-hole (Punch Unit-K1),
or two types of 4-hole (Punch Unit-G1, Punch Unit-H1).
The 2-hole and 4-hole types punch a hole when the punch shaft is
rotated 180° from the home position, causing the punch to make a
single round trip. The 2-/3-hole type punches a hole, but the circumference of the punch shaft is divided into two (half for 2-hole
and the other half for 3-hole).
1) 2-Hole, 4-Hole Type
The home position is identified when the punch home position
sensor (FPHPD) is ON. The punching operation for the first
sheet ends when the punch shaft has rotated 180° and the
punch home position sensor (FPHPD) goes ON; the punching
operation for the second sheet ends when the punch shaft has
rotated 180° in reverse and the punch home position sensor
(FPHPD) goes ON.

2) 2-/3-Hole Type
The home position is identified when the punch home position
sensor (FPHPD) is ON. To make two holes, the punching operation for the first sheet ends when the punch shaft rotates 180°
(half circumference) and the punch home position sensor
(FPHPD) goes ON. At this time, the 3-hole puncher makes a
single round trip in escape direction (moving up the hole
puncher) on a half circumference of the punch shaft. The
punching operation for the second sheet ends when the punch
shaft has rotated 180° counterclockwise and the punch home
position sensor (FPHPD) goes ON (half circumference).
At this time, the 3-hole puncher makes a single round trip in
escape direction (moving up the hole puncher) on the other
half circumference of the punch shaft.
The punching operation takes place as follows when making
two holes in two sheets of paper:

(3) Horizontal Registration Operation
Punch
The horizontal registration drive for the punch slide unit is provided
by the punch horizontal registration motor (FPSM). The home position of the punch slide unit is detected by the punch horizontal registration home position sensor (FPSHPD). The punch slide unit
detects the trailing edge of sheets using the trailing edge sensor
(FPTD) and the horizontal registration sensors (FPSD1 through 4),
and causes a move to a specific position matching the trailing edge
of each sheet (in relation to the size of the sheet).
The horizontal registration operation takes place as follows:
1) When the leading edge of a sheet from the host machine is
detected by the trailing edge sensor (FPTD), the punch horizontal registration motor (FPSM) starts to move the punch
slide unit toward the front.

the rear edge of the sheet, the punch horizontal registration
motor (FPSM) causes a farther move to a specific position,
and stops the punch slide unit.
Horizontal registration sensor 1 (FPSD1);
used to detect the edge of sheets of A3, A4,
8.5" x 11", 11" x 17".
Horizontal registration sensor 2 (FPSD2);
used to detect the edge of sheets of B4, B5,
8.5" x 11"R, 8.5" x 14".
Horizontal registration sensor 3 (FPSD3);
used to detect the edge of sheets of A4R.
Horizontal registration sensor 4 (FPSD4);
used to detect the edge of sheets of B5R.
3) When the trailing edge sensor (FPTD) detects the trailing edge
of the sheet, the drive of the feed motor (FFM) is stopped,
thereby stopping the sheet. Then, the punch motor (FPNM) is
driven to punch holes in the sheet.
4) When the punching operation ends, the feed motor (FFM) of
the fisher unit is driven and, at the same time, the punch horizontal registration motor (FPSM) is rotated in reverse to return
the punch slide unit to its home position.
5) For each sheet that arrives in succession, the punch slide unit
is returned to its home position, and is caused to repeat steps
1 through 4.

G. Detecting Jams
(1) Outline
The microprocessor (CPU) on the finisher controller PCB is programmed to check for jams in the finisher/saddle/puncher (option)
at such times as set in advance. It identifies a jam in reference to
the presence/absence of paper at a specific sensor. If a jam is
found, the finisher controller PCB communicates the nature of the
jam to the host machine in the form of a code(which may be
checked in service mode of the host machine).
