[4] 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. All these operations are controlled by various commands sent by the host machine in addition to the commands from the finisher controller PCB. The puncher 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

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.

•IC11 (communication IC) Communicates with the host machine.

•IC1 (regulator IC) Generates 5 V. F02-102-01 shows the flow of signals between finisher and options controller:

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)

(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.

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

(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

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 slide 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 slide home position sensor (SHPS) 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.

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 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.

D.Stapler Unit

The staple/fold 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 home position sensor (STHPS). 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 (SPS) 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 (SS) 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 (FFSM) unless the staple safety switch (SSS) 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 slide motor (FSM). Its home position is detected by the slide home position sensor (SHPS). The stapler waits at the back irrespective of the staple mode and paper size. After paper has been stacked on the processing tray, the stapler is moved to the specified stapling position in response to the stapling command from the host machine. The standby position of the stapler and the stapling position depending on the staple mode are shown below.

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 (FES) to detect presence/absence of paper. The delivery tray in the finisher unit is moved up and down using a shift motor (FLM). The finisher has a tray paper sensor (BES) 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 (STHPS). 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 (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 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 (LE). 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 (ULS). When the shift upper limit sensor (ULS) is turned ON, the finisher controller PCB stops the shift motor (FLM) that is ascending. The lower limit of the delivery tray is detected by the shift lower limit sensor (LLLS). When the shift lower limit sensor (LLLS) is turned ON, the finisher controller PCB stops the shift motor (FLM) 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. 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

b.Stitching

When the center of the paper stack (stitching position) reaches the stapler's staple position, the stapler stitches the paper stack. When only one sheet is fed from the host machine, the next step (stack feed) is performed without performing the stitching operation.

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.

Bind delivery rollers

Paper fold rollers

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.

Stack feed roller (upper)

Feed amount

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 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 folding position sensor (FPS), 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 (FFM) is driven to rotate the stack feed roller (lower) so that the leading edge of the paper stack is not bent.

E.Fold/Delivery System

(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/fold motor (FFSM). The drive force is transferred with a combination of gears and cams. Motor operation is monitored by the staple/fold motor lock sensor (FE). 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 (FHPS) 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 (FFSM). A bind tray sensor (FES) 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.

6. Puncher Unit (option)

A. Basic Operations

(1)Outline

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.

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.

B.Punching Operation

(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 (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 (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 (PE). 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 PT4) 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 (FPSM). The home position of the punch slide unit is detected by the horizontal registration home position sensor (PSHPS), and the horizontal registration motor (FPSM) is a stepping motor.

(2)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 (XXXX). 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 Unit-G1, 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).

a.2-Hole, 4-Hole Type

The home position is identified when the punch home position is ON. The punching operation for the first sheet ends when the punch shaft has rotated 180× and the punch home position sensor 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 goes ON. The punching operation takes place as follows when making a hole in two sheets of paper.

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

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:

(punch shaft at rest/

(punch shaft CW rotation by 180˚/

(3)Horizontal Registration Operation

The horizontal registration drive for the punch slide unit is provided by the horizontal registration motor (FPSM). The home position of the punch slide unit is detected by the horizontal registration home position sensor (PSHPS). 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 (FPSM) starts to move the punch slide unit toward the front.

Horizontal registration home position sensor (P12P)

4) When the punching operation ends, the feed motor (FFM) of the fisher unit is driven and, at the same time, the 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 .

2) When the horizontal registration sensor (LED1 through 4, PT1 through) suited to the paper size signal from the host machine detects the rear edge of the sheet, the horizontal registration motor (FPSM) causes a farther move to a specific position, and stops the punch slide unit.

3) When the trailing edge sensor (LED5, PT5) 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.

7. Detecting Jams

A.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).
