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.

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.

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)

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.

2.3.4 Stack Delivery Operation

Stack delivery takes place when 10 sheets of large-size paper or 30 sheets of small-size
paper (A5- and STMT-sizes: 10 sheets) have been stacked on the processing tray with them
offset in either direction.

The paddle motor rotates and the swing guide descends to hold the paper stack between
the upper and lower stack delivery rollers. The delivery motor 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

3.1 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 slide motor (M8) 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 slide home position sensor
(PI18) on the slide PCB located under the stapler unit. Next, the slide motor 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.

controller PCB drives the paddle motor (M2) 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 controller PCB moves the stapler for stapling according to the specified sta­pling position (when rear 1-point stapling is specified, the stapler does not move but it
staples at the standby position). As the stapler moves forward, the processing tray stopper is
folded forward.

3.3 Delivery Operation after Stapling

When stapling is complete, the finisher controller PCB drives the deliver motor 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 is turned OFF. The delivery mo­tor is driven a specified number of pulses, causing the swing guide to ascend. At the same
time, the slide motor is driven to return the stapler back to the standby position, followed by
driving of the delivery motor. Then, the paper stack is delivered with the nails of the deliv­ery belt that rotates in sync with the stack delivery rollers.

CHAPTER 2 OUTLINE OF OPERATION

3.4 Stapler Unit

The staple/fold motor (M7) 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 home po­sition sensor (PI19).

The staple/fold motor is rotated in the forward or reverse direction under the control of
the macro computer (IC13) on the finisher controller PCB.

When the staple home position sensor is OFF, the finisher controller PCB rotates the
staple/fold motor in the forward direction until the sensor turns ON, allowing the staple cam
to the original position.

The staple empty sensor (PI20) is used to detect presence/absence of a staple cartridge in
the machine and presence/absence of staples in the cartridge.

The stale top position sensor (PI21) is used to determine whether staples are pushed up to
the top of the staple cartridge.

The finisher controller circuit does not drive the staple/fold motor (M7) unless the staple
safety switch (MS3) is ON (the swing guide is close). This assures safety in case where you
happen to put your finger in the stapler.

CHAPTER 2 OUTLINE OF OPERATION

4 Delivery Tray Operation

4.1 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 (PI13) to detect presence/absence of pa­per.

The delivery tray in the finisher unit is moved up and down using a shift motor (M6).

The finisher has a tray paper sensor (PI8) 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
(PI19). 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 shift motor (M6) to return the delivery tray
to the home position.

When the paper coming from the processing tray is stacked on the delivery tray, the shift
motor is driven a specified number of pulses, causing the delivery tray to descend. Clock
pulses are detected by the shift motor clock sensor (PI17). 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 shift upper limit sensor (PI15).
When the shift upper limit sensor (PI15) is turned ON, the finisher controller PCB stops the
shift motor (M6) that is ascending.

The lower limit of the delivery tray is detected by the shift lower limit sensor (PI16).
When the shift lower limit sensor (PI16) is turned ON, the finisher controller PCB stops the
shift motor (M6) that is descending.

The finisher unit has a full stack sensor (PI24) to detect overstacking of large-size or
mixed paper according to the stack height.

5.3 Paper Feed System

5.3.1 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 (M2) 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 delivery motor (M3) rotates in the reverse direction, feeding the paper
stack toward the saddle unit. When the leading edge of the paper stack reaches the folding
position sensor (PI10), the finisher controller PCB drives the delivery motor 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 (M1) is driven to rotate the stack feed roller (lower) so that the leading edge of
the paper stack is not bent.

CHAPTER 2 OUTLINE OF OPERATION

5.5 Fold/Delivery System

5.5.1 Outline

The paper fold mechanism consists of a guide plate, paper fold rollers, and a paper push-

ing plate.

The guide plate, paper fold rollers, and paper pushing plate are driven by the staple/fold
motor (M7). The drive force is transferred with a combination of gears and cams. Motor
operation is monitored by the staple/fold motor lock sensor (PI14).

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 folding home position sensor (PI11) 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/fold motor (M7).

A bind tray sensor (PI13) is provided on the bind tray to detect presence/absence of a pa­per stack; however, it is not used to detect a jam.

CHAPTER 2 OUTLINE OF OPERATION

5.5.2 Paper F olding

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.

The puncher unit is an option, and is designed for installation to the pickup assembly of
the finisher. The puncher unit is not equipped with a paper feeding mechanism, and the
sheets from the host machine move through the puncher unit and then the feed system of the
finisher.

When the trailing edge of a sheet from the host machine reaches the puncher 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.

CHAPTER 2 OUTLINE OF OPERATION

6.2 Punching Operation

6.2.1 Outline

The puncher 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 puncher 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 (M1P). 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 (M1P) is a DC motor. The home position of the punch shaft is detected
by the punch home position sensor (PI1P). To make sure that the punch motor, which is a
DC motor, stops exactly at its home position, the punch motor is stopped in relation to the
count of the clock pulses kept by the punch motor clock sensor (PI3P).

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 puncher 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 to detect the training edge of sheets, and the remaining four (LED1 through LED4,
PT1 through PTR4) are used as horizontal registration sensors to detect the rear position of
sheets when punching holes.

The punch motor, 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
horizontal registration motor (M2P). The home position of the punch slide unit is detected
by the horizontal registration home position sensor (PI2P), and the horizontal registration
motor (M2P) is a stepping motor.

The punch motor and horizontal registration motor 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.

The hole puncher is driven by the punch motor (M1P). The home position for the hole
puncher is detected by the punch home position sensor (PI1P).

The punch unit comes in four types, selected to suit the country of installation: 2-hole
(Puncher Unit-J1), 2- and 3-hole (Puncher Unit-K1), or two types of 4-hole (Puncher Unit­G1, Puncher 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).

CHAPTER 2 OUTLINE OF OPERATION

b. 2- /3-Hole Type

The home position is identified when the punch home position sensor 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 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 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:

1) A hole is made along the trailing edge of the 1st sheet.

CHAPTER 2 OUTLINE OF OPERATION

6.2.3 Horizontal Registration Operation

The horizontal registration drive for the punch slide unit is provided by the horizontal reg­istration motor (M2P). The home position of the punch slide unit is detected by the horizon­tal registration home position sensor (PI2P). The punch slide unit detects the trailing edge of
sheets using the trailing edge sensor (LED5, PT5) and the horizontal registration sensors
(LED1 through 4, SREG1 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 (LED5, PT5), the horizontal registration motor (M2P) starts to move the punch
slide unit toward the front.

7 Detecting Jams

7.1 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).

CHAPTER 2 OUTLINE OF OPERATION

8 Power Supply System

8.1 Finisher/Saddle Assembly

8.1.1 Outline

When the host machine is turned on, it supplies the finisher controller PCB with two
channels of 24 VDC; one is for the motors and clutches, and the other is turned into 5 VDC
by the regulator IC (IC1) of the finisher controller PCB for use by the sensors and ICs on
PCBs.

If a punch unit (option) is installed, power is also supplied to the punch controller PCB.

Some of 24 VDC used to drive motors is cut off when the joint switch (MS2), front door
switch (MS1), or stapler safety switch (MS3) is open.
