2. The AR-F15/F16, AR-PN4 should be installed by an authorized/qualified person.

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

4. When selecting the installation site, avoid placing the AR-F15/F16 and copier on different levels or inclined floors.

5. When servicing or maintaining the AR-F15/F16/AR-PN4, be careful about the rotating or operation sections such as gears, pulleys, sprockets, cams, belts, etc.

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

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

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

9. Use suitable measuring instruments and tools.

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

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

12. For the recovery and disposal of used AR-F15/F16/AR-PN4s, consumable parts, packing materials, used batteries, and RAM-ICs including lithium batteries, it is recommended that the relevant local regulations/rules.

13. After completing installation, servicing and maintenance of the AR-F15/F16/AR-PN4, return the AR-F15/F16/AR-PN4 to its original state, and check operation.

14. When you move the finisher, do not move it in the direction of the arrow as shown in the figure below otherwise it might fall down.

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 sion of mechanical drive, and signals marked by the flow of electrical signals.

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

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

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

CHAPTER 2 FINISHER UNIT BASIC OPERATION

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

delivery include simple stacking, job offset

CHAPTER 2 FINISHER UNIT BASIC OPERATION

B. Outline of Electrical Circuitry

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

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

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

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

●

IC1 (CPU) Controls sequence of operations.

●

IC2 (EP-ROM) Backs up adjustment values.

●

IC3 Contains sequence programs.

●

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

●

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

●

IC9 (regulator IC) Generates PWM.

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

CHAPTER 2 FINISHER UNIT BASIC OPERATION

C. Feeding and Delivering

1. Outline

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

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

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

●

Inlet sensor (PI1)

●

Delivery sensor (PI3)

●

Stapling tray sensor (PI4)

●

Buffer path paper sensor (PI14)

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

●

No.1 tray paper sensor (PI11)

●

No.2 tray paper sensor (PI12)

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

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

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

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

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

ment plate to its home position.

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

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

The finisher controller PCB drives the alignment motor (M3) in advance, and keeps the alignment plate in wait at a point 10 mm behind the trailing edge of a sheet. Whenever one sheet is moved to the stapling tray, each sheet is aligned, and when the 3rd or last sheet in a sort job/group is fed to the stapling tray, the escape solenoid (SL6) moves the guide plate away and under the stapling tray. From then on, the alignment motor shifts the sheets to the front by 30 mm.

When the copy has been shifted, the finisher controller PCB rotates the alignment motor counterclockwise to move the alignment plate to a point 10 mm behind the trailing edge of the sheet. This alignment operation is repeated until alignment of the 3rd or last sheet in a sort job is completed. At this time, the swing guide is moved down and is closed, and the delivery motor rotates clockwise to deliver the sheet.

1. Outline

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

is at the home position.

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

CHAPTER 2 FINISHER UNIT BASIC OPERATION

2. First Sheet

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

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

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

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

3. Second and Subsequent Sheets

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

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

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

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

CHAPTER 2 FINISHER UNIT BASIC OPERATION

F. Stapler Unit

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

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

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

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

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

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

5. Shifting the Stapler Unit

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

CHAPTER 2 FINISHER UNIT BASIC OPERATION

G. Tray Operation

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

move up and down independently.

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

(M10).

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

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

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

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

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

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

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

H. Detecting the Height of Stack on the Tray

1. Outline

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

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

CHAPTER 2 FINISHER UNIT BASIC OPERATION

I. Shutter Operation

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

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

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

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

See the following diagrams for how these operations take place.

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

J. Buffer Path Operation

1. Outline

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

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

The following shows operation on the buffer paper path.

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

K. Detecting Jams

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

sheets are moved properly:

●

Inlet sensor (PI1)

●

Delivery sensor (PI3)

●

Stapling tray sensor (PI4)

●

Buffer path paper sensor (PI14)

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

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

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

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

III. POWER SUPPLY SYSTEM

1. Outline

F15/F16

The finisher controller PCB is supplied with 24 VDC power when the host machine is turned on. Power is also supplied from the finisher controller PCB to the saddle stitch controller PCB. In addition, power is also supplied to the punch driver PCB when the optional puncher unit is mounted.

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

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

Power source

Figure 2-301

2. Protection Functions

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

SADDLE STITCH UNIT

BASIC OPERATION

1. This chapter discusses the purpose and role of each of the saddle stitch functions, and the

principles of operation used for the stitch mechanical and electrical systems. It also explains

the timing at which these systems are operated.

The

by together with the signal name indicates the flow of electrical signals.

2. In descriptions of digital circuits on the stitch, “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 stitch. A description of microprocessor operation is omitted in

this chapter as it is practically impossible to check internal operation of the microprocessor.

Descriptions in this chapter also assume that PCBs will not be repaired at user sites. For this

reason, descriptions of circuits on PCBs is limited to block diagrams. Two types of block dia-

grams 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 STITCH UNIT BASIC OPERATION

I. BASIC OPERATION

A. Outline

The unit “stitches” (2 points) a stack of sheets delivered by the finisher unit and folds it in two for delivery. All these operations are controlled by the saddle stitch controller PCB in response to commands from the host machine via the finisher unit.

CHAPTER 3 SADDLE STITCH UNIT BASIC OPERATION

B. Electrical Circuitry

The sequence of operations used for the saddle stitch is controlled by the saddle stitch controller PCB. The saddle stitch 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 stitch 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 stitch 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.
