General Precautions for Installation/Servicing/Maintenance for the Finisher

AR-FN11/FN12, Hole punch unit AR-PN3, Inserter AR-CF1

The installation and service should be done by a qualified service technician.

1. When installing the Finisher AR-FN11/FN12, Hole punch unit AR-PN3, Inserter AR­CF1 to the Plain Paper Copier, be sure to follow the instructions described in the “Un­packing/Set-Up Procedure for the AR-FN11/FN12/AR-PN3/AR-CF1” booklet which
comes with each unit of the AR-FN11/FN12/AR-PN3/AR-CF1.

2. The AR-FN11/FN12, AR-PN3, AR-CF1 should be installed by an authorized/qualified
person.

3. Before starting installation, servicing or maintenance work, be sure to turn off and un­plug the copier first.

4. When selecting the installation site, avoid placing the AR-FN11/FN12/AR-CF1 and
copier on different levels or inclined floors.

5. When servicing or maintaining the AR-FN11/FN12/AR-PN3/AR-CF1, be careful about
the rotating or operation sections such as gears, pulleys, sprockets, cams, belts, etc.

6. When parts are disassembled, reassembly is the reverse of disassembly unless other­wise noted in this manual or other related materials. Be careful not to reassemble small
parts such as screws, washers, pins, E-rings, toothed washers to the wrong places.

7. Basically, the machine should not be operated with any parts removed or disassembled.

8. Delicate parts for preventing safety hazard problems (such as breakers, thermofuses,
fuses, door switches, sensors, etc. if any) should be handled/installed/adjusted cor­rectly.

9. Use suitable measuring instruments and tools.

10. During servicing or maintenance work, be sure to check the serial No. plate and other
cautionary labels (if any) to see if they are clean and firmly fixed. If not, take appropriate
actions.

11. The PC board must be stored in an anti-electrostatic bag and handled carefully using
a wristband, because the ICs on it may be damaged due to static electricity. Before
using the wrist band, pull out the power cord plug of the copier and make sure that
there is no uninsulated charged objects in the vicinity.

12. For the recovery and disposal of used AR-FN11/FN12/AR-PN3/AR-CF1s, consum­able parts, packing materials, used batteries, and RAM-ICs including lithium batteries,
it is recommended that the relevant local regulations/rules.

13. After completing installation, servicing and maintenance of the AR-FN11/FN12/AR­PN3/AR-CF1, return the AR-FN11/FN12/AR-PN3/AR-CF1 to its original state, and
check operation.

CHAPTER 2

FINISHER UNIT BASIC OPERATION

1. This chapter discusses the purpose and role of each of the finisher’s functions, and the principles
of operation used for the finisher mechanical and electrical systems. It also explains the timing at
which these systems are operated. The symbol in drawings indicates transmission of me­chanical drive, and signals marked by together with the signal name indicates the flow of
electrical signals.

2. In descriptions of digital circuits on the finisher, “1” indicates a high signal voltage level, while
“0” indicates a low signal voltage level. Voltage values differ according to circuit.

A microprocessor is used on the finisher. A description of microprocessor operation is omitted in
this chapter as it is practically impossible to check internal operation of the microprocessor.

Descriptions in this chapter also assume that PCBs will not be repaired at user sites. For this
reason, descriptions of circuits on PCBs is limited to block diagrams. Two types of block dia­grams are provided for separate functions: diagrams indicating details from sensors up to input
sections of major PCBs, and diagrams indicating details from the output sections of major PCBs
up the loads.

CHAPTER 2 FINISHER UNIT BASIC OPERATION

The finisher is designed to deliver copies arriving from its host machine, and its modes of deliv-

ery include simple stacking, job offset

(Note)

, and staple.

All operations involved in these modes are controlled by the finisher controller PCB, according

to the appropriate commands from the host machine.

In the case of the Saddle Finisher, copies from the host machine may be routed to the saddle stitch

unit.

CHAPTER 2 FINISHER UNIT BASIC OPERATION

B. Outline of Electrical Circuitry

The finisher’s sequence of operation is controlled by the finisher controller PCB. The finisher
controller PCB is a 16-bit microprocessor (CPU), and is used for communication with the host ma­chine (serial) in addition to controlling the finisher’s sequence of operations.

The finisher controller PCB responds to the various commands coming from the host machine
through a serial communications line to drive solenoids, motors, and other loads. In addition, it com­municates the finisher’s various states (information on sensors and switches) to the host machine
through a serial communications circuit.

In the case of the Saddle Finisher, the finisher controller PCB not only communicates with the
saddle stitch controller PCB but also communicates the saddle stitch unit’s various states (information
on sensors and switches) to the host machine.

The ICs used on the finisher controller PCB are designed for the following:

●

IC1 (CPU)
Controls sequence of operations.

●

IC2 (EP-ROM)
Backs up adjustment values.

●

IC3
Contains sequence programs.

●

IC6/IC7 (RAM)
Backs up initial setting data.

●

IC4 (communications IC)
Communicates with the host machine and the saddle stitch unit.

●

IC9 (regulator IC)
Generates PWM.

Figure 2-102 shows the flow of signals between the finisher and the options controller.

b. Job Offset

The finisher forwards all copies of each sort job to the stapling tray. The first sort job on the
stapling tray is delivered with a shift to the front of about 30 mm, and the second sort job is delivered
without being shifted. Whether the first copy or the last copy of a sort job should be shifted is deter­mined by the host machine.

2. Saddle Stitch Delivery (Saddle Finisher)

A copy arriving in the finisher from the host machine is routed to the saddle stitch by the paper
deflecting plate. The saddle stitch executes stitching and saddling operations on the copy and then
delivers it to the saddle stitch tray.

For discussions of stacks in the saddle stitch, see Chapter 3.

B. Type of Delivery Paths

The finisher has three different paper paths for delivery, each selected to suit paper size and

delivery mode.

1. Straight Path

When stacking copies shown in Table 2-201, the copies pass under the buffer roller.

Copy size Length or width 182 mm or less
Typical copy examples A5-R, ST-R, thick paper

2. Buffer Paper Path 1

When stacking copies shown in Table 2-202, the copies pass over the buffer roller, increasing the

distance between copies.

Copy size Length and width 182 mm or more
Typical copy examples A3, B4, A4, A4-R, B5, B5-R, LD, LG, LT, LT-R, (excluding

transparencies and thick stock)

3. Buffer Paper Path 2

This is the paper path when copy sizes shown in Table 2-203 are stacked. A maximum of three
copies (three originals or more in the staple mode) are wrapped round the buffer roller, during which
job offset and stapling are performed on the stapling tray.

Copy size Length 182 to 232mm, and width 182 to 297mm
Typical copy examples A4, B5, LT, (excluding transparencies and thick stock)

CHAPTER 2 FINISHER UNIT BASIC OPERATION

C. Feeding and Delivering

1. Outline

The finisher moves copies arriving from the host machine to the delivery tray, stapling tray, or the
saddle stitch unit (Saddle Finisher) according to the mode of delivery. On the stapling tray, the copies
are subjected to job offset or stapling as instructed by the host machine.

The first feed motor (M1), second feed motor (M8) and inlet feed motor (M9) are stepping mo­tors, and delivery motor (M2) is a DC motor. These motors are controlled by the microprocessor
(CPU) on the finisher controller PCB, and rotate either clockwise or counterclockwise.

The paper paths are equipped with the following four sensors for detection of paper (arrival,
passage):

●

Inlet sensor (PI1)

●

Delivery sensor (PI3)

●

Stapling tray sensor (PI4)

●

Buffer path paper sensor (PI14)

In addition, each delivery tray is equipped with a sensor designed to detect the presence/absence
of paper on it.

●

No.1 tray paper sensor (PI11)

●

No.2 tray paper sensor (PI12)

If a copy fails to reach or move past each sensor within a specific period of time, the finisher
controller PCB identifies the condition as a jam, and stops the ongoing operation, and at the same
time, informs the host machine of the condition. When all doors are closed after the paper jam is
removed, the buffer path inlet paper sensor (PI17) checks whether or not copies are being detected in
addition to the above four sensors (inlet sensor, delivery sensor, stapling tray sensor and buffer path
paper sensor). If the sensors detect a copy, the finisher unit judges that paper jams have not com­pletely been removed, and sends the paper jam removal signal to the host machine again.

CHAPTER 2 FINISHER UNIT BASIC OPERATION

D. Job Offset

1. Outline

In the job offset mode, sort jobs and entire copy groups are shifted to the front for delivery to the

tray, and other copies are delivered to the tray without a shift.

The copies are shifted by the alignment plate. The alignment plate is checked by the alignment

plate home position sensor (PI6) to find out whether it is at the home position.

The finisher controller PCB drives the alignment motor (M3) at power-on to return the alignment

plate to its home position.

The finisher controller PCB stops the delivery motor (M2) when the trailing edge of the copy has
moved past the feed roller 2. Then, the finisher controller PCB rotates the delivery motor counter­clockwise, and drives the swing motor (M7). As a result, the drive of the delivery motor is transmitted
to the swing guide to move up the guide. When the swing guide open sensor (PI18) detects the swing
guide, the delivery motor stops, and the swing guide is held at the up position.

When the swing guide has moved up, the feed belts attached to the feed roller 2 move the copy to
the stapling tray. The presence of paper on the stapling tray is monitored by the stapling tray sensor
(PI4). (The first sheet is fed to the stapling tray while the swing guide is moving up.)

The finisher controller PCB drives the alignment motor (M3) in advance, and keeps the align­ment plate in wait at a point 10 mm behind the trailing edge of a sheet. Whenever one sheet is moved
to the stapling tray, each sheet is aligned, and when the fifth or last sheet in a sort job/group is fed to
the stapling tray, the escape solenoid (SL6) moves the guide plate away and under the stapling tray.
From then on, the alignment motor shifts the sheets to the front by 30 mm.

When the copy has been shifted, the finisher controller PCB rotates the alignment motor counter­clockwise to move the alignment plate to a point 10 mm behind the trailing edge of the sheet. This
alignment operation is repeated until alignment of the fifth or last sheet in a sort job is completed. At
this time, the swing guide is moved down and is closed, and the delivery motor rotates clockwise to
deliver the sheet.

1. Outline

The stapler unit staples a stack of as many sheets as specified.
The stapling position differs according to the selected staple mode and paper size.
The stapler unit is checked by the stapler shift home position sensor (PI7) to find out whether it is

at the home position.

When starting operation after power-on, the finisher controller PCB drives the stapler shift motor
(M4) to return the stapler unit to the home position. If the stapler is already at the home position, it is
kept as it is in wait.

CHAPTER 2 FINISHER UNIT BASIC OPERATION

2. First Sheet

The finisher controller PCB stops the delivery motor (M2) as soon as the trailing edge of the first
sheet has moved past the feed roller 2. Then, it rotates the delivery motor clockwise to switch the gear
drive to the swing motor (M7), causing the swing guide to move up. When the swing guide open
sensor (PI18) finds the swing guide at the up position, the swing motor stops, maintaining the swing
guide at the up position.

When the swing guide has moved up, the knurled belts of the feed roller 2 move the sheet to the
stapling tray. (The first sheet is fed to the stapling tray while the swing guide is moving up.) The
presence of paper on the stapling tray is detected by the stapling tray sensor (PI4).

The finisher controller PCB drives the alignment motor (M3) when the stapling tray paper sensor
has detected paper to put sheets in order. The alignment plate is kept in wait in advance at a point 10
mm behind the trailing edge of the paper.

The swing guide is kept in wait at the up position until the last sheet is output onto the stapling
tray.

3. Second and Subsequent Sheets

The finisher controller PCB turns on the belt escape solenoid (SL7) before the trailing edge of the
second and subsequent sheets have moved past the feed roller 2 to make the knurled belt escape. This
operation is performed to reduce the time it takes for the trailing edge of the paper to fall on the
stapling tray, and to improve the product duty. The finisher controller PCB turns on the paddle sole­noid (SL5) as soon as the trailing edge of the second and subsequent sheets have moved past the feed
roller 2, causing the drive of the second feed motor (M8) to rotate the paddle. The sheets are pushed
by the paddle and moved to the stapling tray. Almost simultaneously with the trailing edge of the
sheet falling into the stapling tray, the belt escape solenoid turns off to return the knurled belts that
were in the escape position to its original position, and feed the sheet onto the stapling tray. When the
sheet has been output onto the stapling tray, the finisher controller PCB rotates the alignment motor
(M3) to put the sheets in order.

When the last sheet has been put in order, the finisher controller PCB turns on the alignment
motor (M3) to move the alignment plate to the alignment position (to butt the plate against the stack).
Then, the finisher controller PCB rotates the swing motor (M7) counterclockwise to move down the
swing guide.

The finisher controller PCB moves the stapler according to the staple mode for stapling.

From then on, it rotates the delivery motor (M2) clockwise to deliver the stack to the tray.

CHAPTER 2 FINISHER UNIT BASIC OPERATION

F. Stapler Unit

Stapling is executed by the staple motor (M6). A single rotation of the cam by the motor results in
one stapling operation.

The cam is checked by the staple home position sensor (PI22) to find out whether it is at the home
position.

The stapler motor is controlled by the microprocessor (IC1) on the finisher controller so that it is
rotated clockwise or counterclockwise.

When the stapling home position sensor is off, the finisher controller PCB rotates the stapler
motor clockwise until the sensor turns on so as to return the stapling cam to its initial state.

The presence/absence of the staple cartridge is detected by the staple switch (MS8). The pres­ence/absence of staples inside the staple cartridge is detected by the staple detecting switch (MS9).
The staple edge sensor (PI21) is used to find out whether a staple has been edged out to the end of the
cartridge.

The finisher controller PCB does not drive the staple motor (M6) unless the swing guide closed
detecting switch 2 (MS6) is on (i.e., the swing guide is closed). This is to protect against injuries that
could occur when a finger is stuck inside the stapler.

5. Shifting the Stapler Unit

The stapler unit is moved by the stapler shift motor (M4). Its home position is detected by the
stapler shift home position sensor (PI7). When the start signal arrives from the host machine, the
stapler moves to the center of its movement range. This movement occurs regardless of the selected
mode of delivery, as no specific mode is recognized at this point in time. When the command for

paper size.

G. Tray Operation

The finisher has two delivery trays-upper tray 1 and lower tray 2. The upper and lower trays

move up and down independently.

Tray 1 is moved up and down by the tray 1 lift motor (M5), and tray 2 by the tray 2 lift motor

(M10).

The tray 1 position is detected by counting the clock pulses of tray 1 lift motor clock sensors 1
and 2 (PI9 and PI19) in relation to the tray 1 home position sensor (P18). The tray 2 position is
detected by counting the clock pulses of tray 2 lift motor clock sensors 1 and 2 (PI23 and PI24) in
relation to the tray 2 home position sensor (PI25).

When the tray is already at the home position, it is moved away from the home position once,
then returned to that position.

When both tray 1 and tray 2 are at the home position, the above operation is performed for tray 1
and tray 2 in this order.

The finisher controller PCB moves up and down the tray selected by the host machine so that it
is positioned at the delivery slot.

The upper limit of the tray is detected by the tray coming close detecting switch (MS9). The
finisher controller PCB stops the drive (up) of the tray 1 lift motor (M5) as soon as the tray upper limit
detecting switch turns on.

The height of the stack on the tray is identified by the height sensor (PS1), which measures its
distance from the top of the stack. The tray is moved down when the distance between the top of the
stack and the delivery assembly drops to a specific measurement.

The finisher controller PCB cuts off the +24V power of the tray 1 lift motor (M5) as soon as the
safety zone switch (MS3) turns on while the shutter and the swing guide are open, stopping the
operation of the finisher.

H. Detecting the Height of Stack on the Tray

1. Outline

The number of sheets delivered to the tray and the number of sets (number of stapling operations)
are stored in memory by the finisher controller PCB. The height of the stack is checked by the height
sensor (PS1). See Table 2-204 for the maximum loading capacity of each tray.

The finisher controller PCB stops operation when the conditions in Table 2-204 occur, informing
the host machine that the tray is full.

I. Shutter Operation

When the tray 1 passes the delivery slot, the finisher controller PCB closes the shutter mounted
on the delivery slot before moving the tray, preventing the existing stack on the tray by the delivery
slot and intrusion of the hands.

The shutter moves up (to close) when the second feed motor (M8) rotates counterclockwise, and
is held in position when the motor stops. When the second feed motor rotates counterclockwise once
again, it moves down (to open) to enable delivery.

When the shutter is held at the up position, claws slide out of the swing guide to engage the back
of the shutter. This way, the existing slack and the swing guide engage while the tray is moved,
preventing the guide from opening. The claws slide in when the shutter is moved down to release the
engagement.

The upward movement of the shutter is monitored by the shutter closed detecting switch (MS4),
and the downward movement is monitored by the shutter open sensor (PI5).

See the following diagrams for how these operations take place.

1) The second feed motor rotates counterclockwise to move the shutter up.

J. Buffer Path Operation

1. Outline

This machine is provided with a buffer paper path for continuously receiving paper from the host

machine during stapling and job offset operation on the stapling tray. A maximum of three copies
(three originals or more in the staple mode) are wrapped around the buffer roller. During this time, job
offset and stapling are performed on the stapling tray.

The following shows operation on the buffer paper path.

1) When the first sheet arrives, the buffer inlet solenoid (SL2) remains off. The first sheet enters the
buffer path.

CHAPTER 2 FINISHER UNIT BASIC OPERATION

K. Detecting Jams

The following sensors are used to detect the presence/absence of paper and to make sure that

sheets are moved properly:

●

Inlet sensor (PI1)

●

Delivery sensor (PI3)

●

Stapling tray sensor (PI4)

●

Buffer path paper sensor (PI14)

A jam is identified with reference to the presence/absence of paper at each specific sensor at the

times programmed in the memory of the microprocessor (CPU) on the finisher controller PCB.

When the CPU identifies a jam, it suspends the finisher’s delivery operation and informs the host
machine DC controller of the presence of a jam. After the paper jam is removed, the buffer path inlet
paper sensor (PI17) checks whether or not copies are being detected in addition to the above four
sensors (inlet sensor, delivery sensor, stapling tray sensor and buffer path paper sensor). If the sensors
detect a copy when all doors are closed, the finisher unit judges that paper jams have not completely
been removed, and sends the paper jam removal signal to the host machine again.

The tray 1 paper sensor (PI11) and tray 2 paper sensor (PI12) are not used to detect jams.

CHAPTER 2 FINISHER UNIT BASIC OPERATION

III. POWER SUPPLY SYSTEM

1. Outline

The finisher controller PCB is supplied with 24 VDC power (and 5 VDC power) when the host
machine is turned on. 24 VDC one is used to drive the motor solenoids, while 5 VDC is used for
sensors and ICs on PCBs. Both lines are also used to feed power from the finisher controller PCB to
the saddle stitch controller PCB. Power is also supplied to the punch driver PCB when the optional
puncher unit is mounted.

Some of the 24 VDC power used to drive motors is cut off when the door switch (MS1) is open.
The power to the saddle stitch controller PCB, however, will not be cut off.

Figure 2-301 is a block diagram showing the power supply system.

2. Protection Functions

The 24 VDC power line used to drive motors and solenoids is equipped with a circuit breaker
(CB1) for protection against overcurrent. The 24 V line used to drive the first feed motor (M1),
alignment motor (M3), and stapler shift motor (M4) are equipped with a fuse, which is designed to
blow when an overcurrent occurs.
