MJ-1021 Service Manaul Ver1

General Precautions for Installation/Servicing/Maintenance for the Finisher MJ-1021

The installation and service should be done by a qualified service technician.1. When installing the Finisher MJ-1021 to the Plain Paper Copier, be sure to follow the

instructions described in the “Unpacking/Set-Up Procedure for the MJ-1021” bookletwhich comes with unit of the MJ-1021.

2. The MJ-1021 should be installed by an authorized/qualified person.3. Before starting installation, servicing or maintenance work, be sure to turn off and un-

plug the copier first.4. When selecting the installation site, avoid placing the Finisher/Inserter and copier on

different levels or inclined floors.5. When servicing or maintaining the MJ-1021, be careful about the rotating or operation

sections such as gears, pulleys, sprockets, cams, belts, etc.6. When parts are disassembled, reassembly is basically the reverse of disassembly

unless otherwise noted in this manual or other related materials. Be careful not toreassemble small parts such as screws, washers, pins, E-rings, toothed washers tothe 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 cor-rectly.

9. When servicing the machines with the main switch turned on, be sure not to touch livesections and rotating/operating sections. Avoid exposure to laser radiation.

10. Be sure not to touch high-voltage sections such as the high-voltage transformer andpower supply unit. Especially, the board of these components should not be touchedsince the electirc charge may remain in the condensers, etc. on them even after thepower is turned OFF.

11. Use suitable measuring instruments and tools.12. 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 appropri-ate actions.

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

14. For the recovery and disposal of used MJ-1021, consumable parts and packing mate-rials, it is recommended that the relevant local regulations/rules.

15. After completing installation, servicing and maintenance of the MJ-1021, return theMJ-1021 to its original state, and check operation.

It also explains thetiming at which these systems are operated.The symbol in drawings indicates transmissionof mechanical drive, and signals marked by together with the signal name indicates theflow 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 omittedin 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 thisreason, descriptions of circuits on PCBs is limited to block diagrams. Two types of block dia-grams are provided for separate functions: diagrams indicating details from sensors up to inputsections of major PCBs, and diagrams indicating details from the output sections of majorPCBs up the loads.

CHAPTER 2

FINISHER UNIT BASIC OPERATION

2-1


I. BASIC OPERATION

A. Outline

The finisher is designed to deliver copies arriving from its host machine, and its modes ofdelivery include simple stacking, job offset (Note), and staple.

All operations involved in these modes are controlled by the finisher controller PCB, accordingto the appropriate commands from the host machine.

In the case of the saddle stitch mode, copies from the host machine may be routed to the saddlestitcher unit.

B. Outline of Electrical Circuitry

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

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

The finisher controller PCB not only communicates with the saddle stitcher controller PCB butalso communicates the saddle stitcher unit’s various states (information on sensors and switches) tothe 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 stitcher unit.● IC9 (regulator IC)

Generates PWM.

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

b. Job OffsetThe 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 deliv-ered without being shifted. Whether the first copy or the last copy of a sort job should be shifted isdetermined by the host machine.

B. Type of Delivery Paths

The finisher has three different paper paths for delivery, each selected to suit paper size anddelivery mode.

1. Straight PathWhen 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 1When 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, (excludingtransparencies and thick paper)

3. Buffer Paper Path 2This 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, duringwhich 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 paper)

2-20


C. Feeding and Delivering

1. OutlineThe finisher moves copies arriving from the host machine to the delivery tray, stapling tray, or the

saddle stitcher unit according to the mode of delivery. On the stapling tray, the copies are subjected tojob 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 mo-tors, 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/ab-sence 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 finishercontroller PCB identifies the condition as a jam, and stops the ongoing operation, and at the sametime, informs the host machine of the condition. When all doors are closed after the paper jam isremoved, the buffer path inlet paper sensor (PI17) checks whether or not copies are being detectedin addition to the above four sensors (inlet sensor, delivery sensor, stapling tray sensor and bufferpath paper sensor). If the sensors detect a copy, the finisher unit judges that paper jams have notcompletely been removed, and sends the paper jam removal signal to the host machine again.

D. Job Offset

1. OutlineIn the job offset mode, sort jobs and entire copy groups are shifted to the front or rear for delivery

to the tray, and other copies are delivered to the tray without a shift.The copies are shifted by the front and rear alignment plates. The alignment plate is checked by

the alignment plate home position sensor (PI6, PI29) to find out whether it is at the home position.The finisher controller PCB drives the front and rear alignment motors (M3, M11) 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 coun-terclockwise, and drives the swing motor (M7). As a result, the drive of the delivery motor is trans-mitted to the swing guide to move up the guide. When the swing guide open sensor (PI18) detectsthe 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 copyto the stapling tray. The presence of paper on the stapling tray is monitored by the stapling traysensor (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, M11) in advance, and keeps thealignment plate in wait at a waiting position of the trailing edge of a sheet. Whenever one sheet ismoved to the stapling tray, each sheet is aligned, and the fifth or last sheet in a sort job/group is fed tothe stapling tray. Then the alignment motor shifts the sheets front or rear by 15 mm.

When the copy has been shifted, the finisher controller PCB rotates the alignment motor counter-clockwise to move the alignment plate to a waiting position of the trailing edge of the sheet. Thisalignment operation is repeated until alignment of the fifth or last sheet in a sort job is completed. Atthis time, the swing guide is moved down and is closed, and the delivery motor rotates clockwise todeliver the sheet.

E. Staple Operation

1. OutlineThe 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 homeposition, it is kept as it is in wait.

detected with the delivery sensor (PI3) to escapes the drop lever arm upward. When the sheet passedthrough the delivery sensor, the finisher controller PCB turns off the drop solenoid to lower the droplever arm and drop the trailing edge of the sheet on the stapling tray.

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

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

The finisher controller PCB drives the alignment motors (M3, M11) when the stapling tray papersensor has detected paper to put sheets in order. The alignment plate is kept in wait in advance at apoint 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 staplingtray.

3. Second and Subsequent SheetsThen the finisher controller PCB turns on the paddle motor (M14) as soon as the trailing edge of

the second and subsequent sheets passses the feed roller 2, causing the paddle to rotate once, the sheetis pushed by the paddle and sent to the stapling tray. When the sheet outputs onto the stapling tray, thefinisher controller PCB rotates the alignment motors (M3, M11) to put the sheets in order. When the11th, 21st, 31st or 41st sheet of paper is fed on the stapling tray, the finisher controller PCB turns on theknurled belt motor (M13) to transfer the knurled belts for proper feeding of the sheet.

4. Last SheetWhen the last sheet has been put in order, the finisher controller PCB turns on the alignment

motors (M3, M11) to move the alignment plate to the alignment position (to butt the plate against thestack). Then, the finisher controller PCB rotates the swing motor (M7) counterclockwise to movedown 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.

F. Stapler Unit

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

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

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

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

The staple cartridge is judged as ‘Absence’ when both staple edging sensor (PI21) and staplesensor (PI31) indicate “1”. The presence/absence of staples inside the staple cartridge is detected bythe staple sensor (PI31). The staple edge sensor (PI21) is used to find out whether a staple has beenedged out to the end of the cartridge.

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

Also, this finisher detects the type of staple cartridge when turning on the power. After the car-tridge for stapling 100 sheets is switched to that for stapling 50 sheets or vice versa, be sure turn offthe power then turn it on.

Note:When displaying “Set stapler cartridge” even though the staple cartridge is installed, it may notbe installed correctly. If you move the gear of stapler unit manually, the cartridge cannot bedetected due to the dislocation of gear because it is not correctly installed. In this case, move thegear to the position as shown below and reinstall the cartridge.

5. Shifting the Stapler UnitThe 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, thestapler moves to the center of its movement range. This movement occurs regardless of the selectedmode of delivery, as no specific mode is recognized at this point in time. When the command forstapling arrives from the host machine after the first sheet has reached the host machine pre-registra-tion sensor, the stapler moves to the staple wait position to suit the appropriate stapling position andpaper size.

See Figures 2-235 and later for an idea of the wait position according to the stapling mode.

G. Tray Operation

The finisher has two delivery trays - upper tray 1 and lower tray 2. The upper and lower traysmove 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 1and 2 (PI9 and PI19) in relation to the tray 1 home position sensor (P18). The tray 2 position isdetected by counting the clock pulses of tray 2 lift motor clock sensors 1 and 2 (PI23 and PI24) inrelation 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 tray1 and tray 2 in this order.

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

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

The height of the stack on the tray is identified by the height sensor (PS1), which measures itsdistance from the top of the stack. The tray is moved down when the distance between the top of thestack 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 thesafety zone switch (MS3) turns on while the shutter and the swing guide are open, stopping theoperation of the finisher.

H. Detecting the Height of Stack on the Tray

1. OutlineThe number of sheets delivered to the tray and the number of sets (number of stapling opera-

tions) are stored in memory by the finisher controller PCB. The height of the stack is checked by theheight 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, inform-ing the host machine that the tray is full.

Notes: 1. The capacity for the non-staple sort mode is approximate and computed based on 80 g/m2 paper.2. Alignment for stacks containing 750 sheets or more is not guaranteed.3. Stacking height precision is ±7 mm.4. “Mode mixing” means stacking non-stapled papers and stapled papers.5. The term “Small-size (1)” stands for A4, B5 and LT, the term “Small-size (2)” stands for A5-R and ST-R,

while the term “Large-size (1)” stands for A3, B4, A4-R, LD, LG, LT-R, FOLIO and COMPUTER, “Large-size (2)” stands for B5-R.

I. Shutter Operation

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

The shutter moves up (to close) when the second feed motor (M8) rotates counterclockwise, andis held in position when the motor stops. When the second feed motor rotates counterclockwise onceagain, 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 theback 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 releasethe 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.

M8Second feed motor

2) The tray 1,2 lift motor rotates, and the new tray moves to the stacking lower limit. The distanceof movement is detected by1 the tray 1 lift motor clock sensor 1/2 (PI9/19) or tray 2 lift motorclock sensor 1/2 (PI22/PI24).

J. Buffer Path Operation

1. OutlineThis 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 threecopies (three originals or more in the staple mode) are wrapped around the buffer roller. During thistime, 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 entersthe buffer path.

K. Detecting Jams

The following sensors are used to detect the presence/absence of paper and to make sure thatsheets 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 thetimes 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 thehost machine DC controller of the presence of a jam. After the paper jam is removed, the buffer pathinlet paper sensor (PI17) checks whether or not copies are being detected in addition to the abovefour sensors (inlet sensor, delivery sensor, stapling tray sensor and buffer path paper sensor). If thesensors detect a copy when all doors are closed, the finisher unit judges that paper jams have notcompletely 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.

III. POWER SUPPLY SYSTEM

1. OutlineWhen the host machine is turned on, 5VDC power is supplied to the finisher controller PCB

from the host machine. Then the finisher controller PCB sends the power-on signal (REMOTE) tothe power supply unit. The power is turned on due to this operation, and 24VDC power is suppliedto the finisher controller PCB. 24VDC power is used to drive the motors and the solenoids, while5VDC power is used for sensors and ICs on PCB. Both lines are also used to feed power from thefinisher controller PCB to the saddle stitcher controller PCB. Power is also supplied to the punchdriver 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.However, the power to the saddle stitcher controller PCB and the punch driver PCB will not be cutoff.

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

1. This chapter discusses the purpose and role of each of the stitcher’s functions, and the principlesof operation used for the stitcher mechanical and electrical systems. It also explains the timing atwhich 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 stitcher, “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 stitcher. A description of microprocessor operation is omitted inthis 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 thisreason, descriptions of circuits on PCBs is limited to block diagrams. Two types of block dia-grams are provided for separate functions: diagrams indicating details from sensors up to inputsections of major PCBs, and diagrams indicating details from the output sections of major PCBsup the loads.

II. FEEDING/DRIVE SYSTEM

A. Outline

The stitcher unit aligns the sheets coming from the finisher unit and stitches the resulting stackfor delivery to the delivery tray according to the commands coming from the finisher controllerPCB.

The machine’s operation consists of the following:1. Receive sheets.2. Aligns the sheets3. Stitches the stack.4. Feeds the stack.5. Folds and delivers the stack.

1) Receive sheets

4) Feeds the stack

3) Stitches the stack

5) Folds and delivers the stack

2) Aligns the sheets

Figure 3-201

3-9


1. Receiving SheetsThe stitcher unit receives sheets from the finisher unit and outputs them inside the vertical path

in vertical orientation.The vertical path, while sheets are being output, is configured by two paper deflecting plates.The position of the sheets being output is set by the paper positioning plate so that the center of

the stack matches the stapling/folding position.Sheets coming later are output closer to the delivery slot, and the volume of paper that may be

output is as follows:● 15 sheets (maximum of 14 sheets of 80 g/m2 + 1 sheet of 256 g/m2)

Paper positioning plate


Direction of delivery

Figure 3-202

3-10


2. Aligning the SheetsThe alignment plates operate to put the sheets in order each time a sheet of paper is output to

the vertical path assembly. The alignment plates are mounted at the edge of the vertical path assem-bly.

The alignment plates also operate after stapling to prepare the stack for delivery.

Sheets


Alignment plateAlignment plate

Figure 3-203

3-11


3. StitchingWhen all sheets have been output, the two stitchers stitch the stack. The stitchers are positioned

so that they face the center of a stack.The two stitchers are not operated simultaneously so as to prevent the paper from wrinkling

between two staples and to limit the load on the power supply.If only one sheet of paper arrives from the host machine, stitching does not take place and the

sequence goes to the next operation (stack feeding).

Figure 3-204

3-12


4. Feeding the StackThe unit folds the stitched stack of sheets, and then feeds it to the point of delivery. This point

is where the center of the stack, i.e., stapling position, matches the height of the paper pushing plateand the paper folding roller nip.

The stack is moved forward by operating the paper positioning plate. When the plate is oper-ated, the guide plate which has been covering the paper folding rollers, also moves down so that thepaper folding rollers directly face the stack.

5. Folding/Delivering the StackThe paper pushing plate pushes against the center of the stack to move it in the direction of the

paper folding rollers. In response, the paper folding rollers pick the stack along its center and foldit in two. The paper folding rollers together with the delivery roller then move the stack along tooutput it on the delivery tray.

III. PAPER OUTPUT MECHANISM

A. Outline

The paper output mechanism serves to keep a stack of sheets coming from the finisher in placefor the next steps (stapling, folding).

The paper inlet is equipped with the No.1 flapper and the No.2 flapper, which operate to con-figure the paper path to suit the size of paper. The paper positioning plate is kept in wait at apredetermined location to suit the size of paper. The paper positioning plate is driven by the paperpositioning plate motor (M4S), and the position of the plate is identified in reference to the numberof motor pulses coming from the paper positioning plate home position sensor (PI7S). A sheetmoved by the inlet roller is handled by the feed rollers and the crescent roller and held in a predeter-mined position. The feed plate serve to move sheets by coming into contact with or moving awayfrom sheets as needed.

The alignment plates put the stack into order each time a sheet is output. The alignment platesare driven by the alignment motor (M5S), whose position is identified in reference to the number ofmotor pulses coming from the alignment plate home position sensor (PI5S).

To prevent interference between paper and the paper folding rollers when the paper is beingoutput, the folding rollers are designed to be covered by a guide plate. The guide plate moves downbefore paper is folded so as to expose the paper folding rollers.

The inlet is equipped with the No.1, No.2 and No.3 paper sensors (PI18S, PI19S, PI20S) eachsuited to a specific paper size, and the paper positioning plate is equipped with a paper positioningplate paper sensor (PI8S).

B. Controlling the Inlet Flappers

1. OutlineThe two flappers mounted at the paper inlet are operated to configure the feed path according to

the size of paper. The flappers are used to enable the following:1. To detect the passage of the trailing edge of the paper being moved by an appropriate sensor.2. To prevent the following sheet from butting against the top of the existing stack,

Table 3-301 shows the relationship between sensors and paper sizes.

C. Controlling the Movement of Sheets

When the leading edge of a sheet has moved past the inlet flapper, the intermediate feed rollerand the crescent roller start to move the sheet forward.

The intermediate feed roller is normally not in contact with the path bed. When the leadingedge of a sheet reaches the intermediate feed roller contact section, the feed plate contact solenoid(SL4S) causes the roller to come into contact with the path bed so as to move the sheet. The contactis broken as soon as the leading edge of the sheet reaches the paper positioning plate. This series ofoperations is executed each time a sheet arrives.

When the leading edge of the first sheet reaches the paper positioning plate, the paper position-ing plate paper sensor (PI8S) turns ON. The arrival of the second and subsequent sheets will not bechecked since the first sheet will still be over the sensor.

The crescent roller keeps rotating while sheets are being output, butting the leading edge ofeach sheet against the paper positioning plate, and ultimately, keeping the leading edge of the stackin order.

The alignment plate motor (M5S) drives the alignment plates for each sheet so as to put bothleft and right edges of the sheet in order.

1) The solenoid turns ON while paper is being moved so that the feed plate comes into contact.

D. Aligning the Sheets

The alignment motor (M5S) drives the alignment plates each time a sheet is output, puttingboth left and right edges of the sheet in order. The alignment plate motor is a 4-phase steppingmotor. The position of the alignment plate is identified in reference to the number of motor pulsesfrom the alignment plate home position sensor (PI5S).

The following briefly describes what takes place when the saddle stitching mechanism oper-ates on two sheets.

1) When the first sheet has been output, the alignment plates butt against the left and right edgesof the stack (first alignment). The alignment plates leave the home position in advance andremain in wait at points 10 mm from the edges of the stack.

3) The alignment plates escape to points 10 mm from the edge of the stack.

4) When the following stack arrives, steps 1 through 3 above are repeated.5) The alignment plates butt against the stack once again, during which stitching takes place.

E. Controlling the Phase of the Crescent Roller

1. OutlineIf alignment was executed with the crescent roller in contact with the stack of sheets, the result-

ing friction against the roller causes the stack to move inappropriately (Figure 3-317). To preventthis problem, the phase of the roller is identified and used to determine the timing of alignment.

The phase of the crescent roller is identified by the crescent roller phase sensor (PI12S). Theflag for the crescent roller phase sensor is mounted to the crescent roller shaft. The flag will leavethe sensor while the roller shaft rotates, turning the sensor ON or OFF, enabling the assumption thatthe crescent roller is positioned at the opposite side of the stack (Figure 3-319). The alignmentplates are operated to correspond with this change in the state of the sensor.

IV. STITCHING SYSTEM

1. OutlineThe stitching system “stitches” the center of an output stack with staples.To enable stitching at two locations on a stack, two stitcher units (front, rear) are used. Each

stitcher unit is equipped with a stitcher motor (M7S, M6S) for drive, a stitcher home positionsensor (MS7S, MS5S) for detection of position and a staple sensor (MS6S, MS4S) for detection ofthe presence/absence of staples.

The stitcher base is designed so that it may be drawn out to the front from the saddle stitcher forreplacement of the staple cartridge or removal of a staple jam. The stitcher unit in sensor (PI16S) isused to make sure that the stitcher base is properly fitted to the saddle stitcher.

Safety switches are not mounted for the stitcher unit (front, rear), as the location does not allowaccess by the user.

2. Stitcher Unit OperationThe stitcher base unit consists of two stitchers and stitcher bases. The stitchers are fixed in

position, and are not designed to slide or swing.Stitching is executed by driving the rotary cam by the stitcher motor (M7S, M6S). The front

and rear stitcher units are operated with a time delay so as to prevent wrinkling of paper and to limitthe load applied to the power supply. (A time delay for initiating the stitcher motor startup currenthelps decrease the load on the power supply.)

The stitcher home position sensor (MS7S, MS5S) is used to monitor the movement of therotary cam, enabling identification of individual stitcher operations. The presence/absence of staplesinside the staple cartridge fitted to the stitcher is detected by the staple sensor (MS6S, MS4S).

The alignment plates keep both edges of the stack in place while stitching takes place.

V. FOLDING/DELIVERY SYSTEM

1. OutlineThe paper folding mechanism consists of a guide plate, paper folding rollers, paper pushing

plate, and paper positioning plate.The guide plate is used to cover the folding rollers while sheets are output so as to prevent

sheets from coming into contact with the folding rollers during output. Before the stack is folded,the guide plate moves down to enable the folding rollers to operate.

The folding rollers are driven by the paper folding motor (M2S), and the drive of the motor ismonitored by the paper folding motor clock sensor (PI4S). The mechanism is also equipped with apaper folding home position sensor (PI21S) for detecting the position of the paper folding rollers.

The paper pushing plate is driven by the paper pushing plate motor (M8S), and the drive of thepaper pushing plate motor is monitored by the paper pushing plate motor clock sensor (PI1S). Thepaper pushing plate home position sensor (PI14S) and the paper pushing plate top position sensor(PI15S) are used to detect the position of the paper pushing plate.

After being folded into two by the paper folding rollers, a stack is moved ahead by the deliveryroller for delivery. The delivery roller is driven by the paper folding motor. The delivery sensor(PI11S) is mounted to the delivery assembly to detect delivery of paper. The tray paper sensor(PI6S) is used to detect the presence/absence of paper on the tray, but does not detect jams. Thevertical path paper sensor (PI17S) serves to detect the presence of paper after jam removal.

3-32


2. Controlling the Movement of StacksWhen a stack has been stitched (2 points), the paper positioning plate lowers so that the stack

will move to where the paper folding rollers come into contact with the stack and where the paperpushing plate is located. The position of the paper positioning plate is controlled in reference to thenumber of motor pulses coming from the paper positioning home position sensor (PI7S).

At the same time as the paper positioning plate operates, the guide plate lowers so that foldingmay take place.

3. Folding a StackA stack is folded by the action of the paper folding rollers and the paper pushing plate.The paper pushing plate pushes against the center of a stack toward the roller contact section.

The paper pushing plate starts at its home position and waits at the leading edge position until thestack has been drawn to the paper folding roller and is gripped for a length of 10 mm. When thepaper folding roller has gripped the stack for a length of about 10 mm, the paper pushing platemotor starts to rotate once again, and the paper pushing plate returns to its home position. The stackgripped in this way by the paper folding roller is drawn further by the paper folding roller and thenis moved by the delivery roller to the paper tray.

Half of the peripheral area of the paper folding rollers excluding the center part is punched out.This punched out area only feeds the paper as the paper feeding roller (lower) contacts the paperfeeding roller (upper) only at the center of the roller to prevent the paper from wrinkling. As thepaper feeding roller (lower) contacts the paper feeding roller (upper) at their entire surfaces on theremaining half of the peripheral area, paper folding starts from this half of the peripheral area, andpaper is fed while it is being folded. The stop position of the paper folding rollers is in this half ofthe peripheral area.

The paper folding start and stop positions on the paper folding rollers is controlled according tothe motor clock signals from the paper folding home position sensor (PI21S).

4. Double Folding a StackTo fold a stack consisting of 10 or more A4-R or LT-R sheets, folding is executed twice for the

same sheet.The paper folding rollers rotate in reverse for an equivalent of 20 mm after gripping the stack

for a length of 20 mm, enabling the paper folding rollers to apply an increased degree of pressurealong the crease on the stack. Then, the paper folding rollers rotate normally, and the paper pushingplate returns to its home position while the stack is being delivered.

This way, a stack requiring a large force may properly be folded with less pressure.

1) The paper pushing plate pushes the stack in the direction of the paper folding rollers.

Vertical path paper sensor (PI17S) or delivery sensor (PI11S) on the paper sensor PCB detectspaper at power-ON.

7. Door Open JamThe front door open/closed sensor (PI2S), outlet cover sensor (PI3S), or inlet cover sensor

(PI9S) finds that the respective cover is open during operation.

8. Stitcher Staple JamWhen the stitcher motor (M7S/M6S) is rotating clockwise, the stitcher home position sensor

(MS7S/MS5S) does not turn ON within 0.5 secs after it has turned OFF. In addition, the sensorturns ON within 0.5 secs after the motor has been rotated counterclockwise.

9. Saddle Feeding Delay Jam (by the paper sensor for the paper positioning plate)The paper sensor for the paper positioning plate is not turned ON at the start of the push (fold-

ing) operation.

Reference:When all doors are closed after the user has removed the jam, the saddle stitcher unit checks whetherthe vertical path paper sensor (PI17S) has detected the presence of paper. If the sensor has detectedpaper, the unit will identify the condition as being faulty jam removal and send the jam signal to thehost machine once again.

VII. POWER SUPPLY

1. OutlineWhen the host machine power switch is turned ON, 24V and 5V power lines are supplied by

the finisher controller PCB.The 24V power is used to drive solenoids. The 24V power from the finisher controller PCB to

solenoids does not pass through any protective mechanisms (microswitches, or the like).The 24V power to motors, on the other hand, will not be supplied if any of the three door

switches is open.The 5V power is used to drive sensors and ICs.

B. Electrical System (saddlestitcher unit)

1. Adjusting the Folding PositionThe folding position is adjusted by chang-

ing the settings of bits 6 through 8 of DIPSW1on the saddle stitcher controller PCB to matchthe stitching position (i.e., adjusting the distanceover which the paper positioning plate is movedto the folding position from the stitching posi-tion.)

If you have replaced the saddle stitcher con-troller PCB, be sure to set the new DIPSW1 sothat the settings will be the same as those on theold DIPSW1. If, for any reason, you mustchange the following position, perform the fol-lowing steps:1) Remove the PCB cover, and set bits 1

through 4 of DIPSW1 on the saddle stitchercontroller PCB as indicated.

9) Change the settings of bits 6 through 8 onDIPSW1 referring to Table 6-102 below.

• If the width adjustment is “0”,The stitching position and the folding posi-tion match, requiring no change.

• If for “positive width adjustment,”Set DIPSW1 so that the difference result-ing from subtraction of the interval from theappropriate setting in Table 6-102 is pro-vided.For instance, if the DIPSW1 is currently setto +2 and the interval is +1 mm, setDIPSW1 to reflect -2.

• If for “negative width adjustment”Set DIPSW1 so that the sum resulting fromaddition of the interval from the appropri-ate setting is provided.For instance, if the DIPSW1 is currently setto -1 and the interval is +0.5 mm, setDIPSW1 to reflect +1.
