CHAPTER 1 GENERAL DESCRIPTION
I. FEATURES
1. Accommodates large quantities of sheets.
• Normally, the finisher holds a stack of sheets 147 mm in height in its two bins (small-size
paper: equivalent to 1000 sheets)/74 mm in height (large-size paper: equivalent to 500 sheets)
2. Has high paper transportation performance.
• The finisher is capable of handling paper between 60 and 200 g/m2.
3. Offers a job offset function.
• The finisher has a job offset function for sorting non-stapled stacks of copies.
4. Offers four types of auto stapling.
• The finisher offers a choice of four stapling modes (1-point stapling at rear, diagonal stapling
at front, diagonal stapling at rear, 2-point stapling).
5. Uses a buffer roller.
• The use of a buffer roller enables the finisher to accept copies without interruption from the
host machine even during stapling or offset operation.
6. Has a saddle stitch function (Saddle Finisher).
• The finisher can staple along the center of paper and fold it in two (up to 15 sheets).
7. Offers a punch function (option).
• The use of the puncher unit enables the finisher to punch sheets for binders before they are

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

I. BASIC OPERATION
A. Outline
CHAPTER 2 FINISHER UNIT BASIC OPERATION
The finisher is designed to deliver copies arriving from its host machine, and its modes of
delivery include simple stacking, job offset
(Note)
, and stapling.
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
stitcher unit.

Page 38
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 stitcher controller PCB but also imparts the saddle stitcher 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:
●
Q1 (CPU)
Controls sequence of operations.
●
Q2 (EEP-ROM)
Backs up adjustment values.
●
Q7
Contains sequence programs.
●
Q8/Q89 (RAM)
Backs up initial setting data.
●
Q4 (communications IC)
Communicates with the host machine and the saddle stitcher unit.
●
Q14 (regulator IC)
Generates 5V.
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.
Tray
Each sort job is stacked
alternately.

2. Saddle Stitch Delivery (Saddle Finisher)
A copy arriving in the finisher from the host machine is routed to the saddle stitcher by the
paper deflecting plate. The saddle stitcher executes stitching and saddling operations on the copy
and then delivers it to the saddle stitcher tray.
For discussions of stacks in the saddle stitcher, see Chapter 3.

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 stapling 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 stitcher 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, anddelivery motor (M2) is a C 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)
●
elivery 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.

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 guide. The alignment guide is checked by the align-
ment 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 align-
ment guide to its home position.
The finisher controller PCB stops the delivery motor (M2) when the trailing edge of the copy
has moved past 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 knurled belts attached to 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 guide 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 guide to a point 7 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.

E. Stapling Operation
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 waiting as it is.

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 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 feed belts of 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 sensor has
detected paper to put sheets in order. The alignment plate is kept waiting in advance at a point 10
mm behind the trailing edge of the paper.
The swing guide is kept waiting at the up position until the last sheet is output onto the stapling
tray.

3. 2nd 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 feed roller 2 to make the feed 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
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 is turned off to return the feed
belts that were in the escape position to their 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.

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

CHAPTER 2 FINISHER UNIT BASIC OPERATION
F. Stapler Unit
Stapling is executed by the stapler motor (M6). A single rotation of the cam by the motor
results in one stapling operation.
The cam is checked by the stapling home position sensor (PI22) to find out whether it is at the
home position.
The stapler motor is controlled by the microprocessor (Q1) on the finisher controller to enable
it to be rotated clockwise or counterclockwise.
When the stapling home position sensor is off, the finisher controller PCB rotates the stapler
motor clockwise until the sensor is turned on so as to return the stapling cam to its initial state.
The presence/absence of staples inside the staple cartridge is detected by the staple switch
(MS8).
The finisher controller PCB does not drive the stapler motor (M6) unless the swing guide
closed detecting switch 2 (MS6) is on (i.e., the swing guide is closed). This is to guard 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
stapling arrives from the host machine after the first sheet has reached the host machine pre-registration sensor, the stapler moves to the staple wait position to suit the appropriate stapling position
and paper size.
See Figures 2-235 and later for an idea of the waiting position according to the stapling mode.

CHAPTER 2 FINISHER UNIT BASIC OPERATION
G. Tray Operation
The finisher has two delivery trays for normal delivery, each accepting sheets.
Each tray is moved up and down by the tray lift motor (M5).
The position of tray is identified with reference to the number of clock pulses of the tray lift
motor clock sensor 1/2 (PI9/PI19) coming from the tray home position sensor (PI8). The finisher
controller PCB finds out in which direction (up or down) the tray is moving based on combinations
of pulses from the two clock sensors.
The finisher controller PCB drives the tray lift motor (M5) to return the tray to the home
position at power-on. If the tray is already at the home position, it is kept waiting as it is.
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 upper limit detecting switch (MS5). The
finisher controller PCB stops the drive (up) of the tray lift motor (M5) as soon as the tray upper
limit detecting switch is turned 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 lift motor (M5) as soon as the
safety zone switch (MS3) is turned on while the shutter and the swing guide are open, stopping the
operation of the finisher.

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 2-201 for the maximum loading capacity of each tray.
The finisher controller PCB stops its operation when the conditions in Table 2-201 occur,
informing the host machine that the tray is full.

I. Shutter Operation
Before the tray on which sheets are output is shifted by the tray lift motor (M5) to another tray,
the finisher controller PCB closes the shutter mounted on the delivery slot before moving the tray,
protecting the existing stack on the tray from the delivery slot and intrusion of 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 stapling mode) are wrapped around the buffer roller. uring
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.

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)
●
elivery 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 C controller of the presence of the jam.
The tray 1 paper sensor (PI11) and tray 2 paper sensor (PI12) are not used to detect jams.

III. POWER SUPPLY SYSTEM
1. Outline
The finisher controller PCB is supplied with 24V C and 5V C power when the host machine
is turned on, 24V C is used to drive the motor solenoids. 5V C is used for sensors and ICs.
24V C and 5V C are also used to feed power from the finisher controller PCB to the saddle
stitcher controller PCB. Power is also supplied to the punch driver PCB when the optional puncher
unit is mounted.
Some of the 24 V C power used to drive the motors is cut off when the door switch (MS1) is
open. The power to the saddle stitcher 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 V C 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.

2. In descriptions of digital circuits on the stitcher, “1” indicates a high signal voltage level, while
“0” indicates a low signal voltage level. Voltage values differ according to the circuit.
A microprocessor is used on the stitcher. A description of microprocessor operation is omitted
in this chapter as it is practically impossible to check the 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 are 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 3 SADDLE STITCHER UNIT BASIC OPERATION
B. Electrical Circuitry
The sequence of operations used for the saddle stitcher is controlled by the saddle stitcher
controller PCB. The saddle stitcher controller PCB has a microprocessor. This microprocessor is
used to control the sequence of operations and to handle serial communications with the finisher
controller PCB, driving solenoids and motors in response to the various commands from the finisher controller PCB.
The saddle stitcher controller PCB is also used to communicate the state of various sensors and
switches to the finisher controller PCB in serial.
The functions of the major ICs mounted on the saddle stitcher controller PCB are as follows:
●
Q1
Controls the sequence of operations.
●
Q2
Contains the sequence program.
●
Q3
Controls the sequence of operations.
●
Q4
Handles IPC communications.
