General Precautions for Installation/Servicing/Maintenance for MJ-1103/1104

The installation and service should be done by a qualified service technician.

1. When installing the MJ-1103/1104, be sure to follow the instructions described in the “Unpacking/ Set-Up Procedure for the MJ-1103/1104”.

2. The MJ-1103/1104 should be installed by an authorized/qualified person.

3. The Finisher is quite heavy; MJ-1103 weighs approximately 40 kg (88.19 lb.) and MJ-1104 weighs approximately 70 kg (154.32 lb.), therefore pay full attention when handling it.

4. Before starting installation, servicing or maintenance work, be sure to turn OFF and unplug the equipment first.

5. The equipment shall be installed near the socket outlet and shall be accessible.

6. Be sure to fix and plug in the power cable securely after the installation so that no one trips over it.

7. When selecting the installation site, avoid placing the finisher / hole punch unit and equipment on different levels or inclined floors.

8. The equipment shall be installed near the socket outlet and shall be easily accessible.

9. When the MJ-1103/1104 is removed from the equipment due to malfunction or other reasons but no substitute machine is to be installed, be sure to remove all the installation hardware from the equipment as well.

10.When servicing or maintaining the MJ-1103/1104, be careful about the rotating or operation sections such as gears, pulleys, sprockets, cams, belts, etc.

11.When parts are disassembled, reassembly is basically 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, harnesses to the wrong places.

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

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

14.Use suitable measuring instruments and tools.

15.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.

16.The PC board must be stored in antistatic envelope 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 cable plug of the equipment and make sure that there is no uninsulated charged objects in the vicinity.

17.For the recovery and disposal of used MJ-1103/1104, consumable parts and packing materials, follow the relevant local regulations/rules.

18.After completing installation, servicing and maintenance of the MJ-1103/1104, return the MJ-1103/ 1104 to its original state, and check operation.

19.When the equipment is used after the option is removed, be sure to install the parts or the covers which have been taken off so that the inside of the equipment is not exposed.

20.When you move the finisher, do not move it in the direction of the arrow as shown in the figure below otherwise it might topple over.

21.Unplug the power cable and clean the area around the prongs of the plug and socket outlet once a year or more. A fire may occur when dust lies on this area.

Finisher

Equipment

Converter PC board

The 2 lines; TxD and RxD are used to transmit/receive signals between the equipment and the Finisher. When the Finisher is connected, the equipment detects the power supply signal (MFP-24V-ON) and confirms that the Finisher is connected to it with the status of the connection switch (SW4) and an MFPCONNECT-SEN signal from the connection sensor (S25).

TXD: Sent data (transmitted from the Equipment to the Finisher) RXD: Received data (transmitted from the Finisher to the Equipment) MFP-24-V-ON: Equipment 24V power supply signal (Low level - 24V power supplied) MFP-CONNECT: Equipment connection switch (Connected - 24V power supplied) MFP-CONNECT-SEN: Equipment connection confirmation signal

(Low level - Connected to the equipment)

Data communication (RxD and TxD) between the equipment and the Finisher has adopted the serial communication system which does not allow checking whether the signals are transmitted/ received properly using testing devices in the field.

3. DESCRIPTION OF OPERATIONS

3.1 Basic Operations

3.1.1 GENERAL DESCRIPTION

This machine receives paper transported from the connected device with its junction box, and then transports the paper to the stationary tray or the movable tray of the Finisher section or the saddle tray of the saddle stitch section. Stack modes available in the Finisher section are; the simple stack mode which directly exits paper to the stationary tray or the movable tray, the job offset stack mode which exits stacks of paper by slightly shifting them to the front and rear alternately, and the staple stack mode which staples and exits stacks of paper. In the job offset stack mode and the staple stack mode, stacks of paper are exited to the movable tray. A stack mode available in the saddle stitch section is the center-binding mode which binds a stack of paper at its center by stapling at two positions and then folds in half again to exit it to the saddle tray.

• Simple stack mode When the non-sort mode is set, paper exits in the procedure shown below. A Paper is output to the stationary tray. B Paper is output to the movable tray via the buffer tray.

Paper transported from the connected device is then detected by the feeding sensor (S22) and caught with the feeding roller. Then it is transported to the Finisher section or the saddle stitch section after the transport path switching solenoid (SOL5) switches its transport path with a flapper. When it is transported to the Finisher section, the flapper does not move but the entrance roller transports it to the Finisher section. When it is transported to the saddle stitch section, the transport path switching solenoid (SOL5) is turned ON to switch the transport path with the flapper. The paper is then transported to the saddle stitch section with the junction roller. The junction box paper detection sensor (S26) detects the passing of the paper. The feeding roller and the junction roller are driven by the entrance motor (M1) of the Finisher section.

In this mode the transported paper is exited to the stationary tray or the movable tray directly, without any extra operation. During the exiting process to the movable tray, the shutter is lifted not to bring the paper into the finishing tray side and the movable tray is lifted up and down according to the stack height of paper.

[A] Finisher paper feeding section

Paper transported from the junction box is then caught with the entrance roller driven by the entrance motor (M1). When paper is exited to the stationary tray, the gate solenoid (SOL4) is turned ON to move down the gate flapper. When exited to the movable tray, the gate solenoid (SOL4) is turned OFF to transport the paper to the buffer tray. The paper transport is detected by the entrance sensor (S1).

[D] Operation of Movable Tray

The movable tray is shifted up and down by the drive from the movable tray shift motor (M12) according to the paper exit from the buffer tray or finishing tray, and the amount of the paper stack. Rotation of the movable tray shift motor is detected by the movable tray shift motor sensor (S23). Whether paper is set on the movable tray or not is detected by the movable tray paper sensor (S17).

Detecting the position of the movable tray is performed as follows.

1. Home position of the movable tray when the paper is output from the buffer tray The movable tray is shifted up during initializing until the movable tray paper-full sensor (S16) is turned ON. After that, the tray is moved down for a specified period of time and it is stopped where the movable tray position-A sensor (S13) is turned ON. This will be the home position.

2. Home position of the movable tray when the paper is output from the finishing tray The movable tray is shifted down from the home position when the paper is output from the buffer tray, and the tray is stopped where the movable tray position-C sensor (S15) is turned ON. This will be the home position.

3. Position of the movable tray when the paper loading capacity is 1,500 to 3,000 sheets If the movable tray paper-full sensor (S16) is turned ON when the movable tray is in either the home position when the paper is output from the buffer tray or the home position when the paper is output from the finishing tray, it goes down to the position where the movable tray position-B sensor (S14) is turned ON. This is the position of the movable tray when the paper loading capacity is 1,500 to 3,000 sheets.

4. Position of the movable tray when the paper loading capacity is 3,000 sheets or more When the movable tray is in the position of the paper loading capacity of 1,500 to 3,000 sheets, and the movable tray paper-full sensor (S16) is turned ON, the tray is shifted to the position where the movable tray position-A sensor (S13) is turned OFF. This is the position of the movable tray when the paper loading capacity is 3,000 or more.

3.1.4 Job offset stack mode / Staple stack mode

The job offset stack mode exits stacks of paper by slightly shifting them to the front and rear alternately, and the staple stack mode staples and exits stacks of paper. In both modes, paper transported from the feeding section is stacked on the buffer tray in the unit of 1 to 3 sheets. The stacked paper is then moved to the finishing tray by the active drop mechanism. On the finishing tray the alignment of the stacks of paper and the job offsetting are performed. In case a stack mode shifts to the staple stack mode after this, the stack of paper is stapled and exited to the movable tray.

[A] Paper transport section

At this stage, the buffer roller lift solenoid (SOL2) is turned ON to raise the buffer rollers and the buffer tray is moved by the buffer tray guide motor (M2) to the position where it matches with the paper width. The home position of the buffer tray is detected by the buffer tray home position sensor (S5).

The paper transported to the buffer tray is then moved to the finishing tray by the mulch-active drop mechanism to be aligned or stapled.

(1) The paper on the buffer tray is pulled into the finishing tray side by the reverse rotation of the

buffer roller drive motor (M4). In this step the paper pushing arm motor (M10) holds the trailing edge of the paper with the paper pushing plate. Then the catching solenoid (SOL1) is turned ON to rotate the catching pad, and the catching pad thus catches the paper with the paddle guides.

the buffer tray guide motor (M2) opens the buffer tray. The paper on the buffer tray is thus dropped onto the finishing tray. At this stage, the patting solenoid (SOL3) is turned ON to drop the paper tapping arm so that the paper will certainly be dropped onto the finishing tray.

(3) The paper dropped onto the finishing tray is then pulled into the finishing position by the paddles

driven by the paddle motor (M8) and the stack transport rollers-1 and -2 driven by the transport motor (M7). The finishing tray paper detection sensor (S12) detects whether paper is on the finishing tray or not. The home position of the paddles is detected by the paddle home position sensor (S3).

The bundle job offset operation is to sort bundles of paper by placing the first bundle a little forward and placing the next bundle a little backward, and repeating this set of movement. The paper transported to the finishing tray is bundled and each bundle is placed by the alignment plates driven by the front alignment motor (M5) and the rear alignment motor (M6). The home position of each alignment plate is detected by the front alignment plate home position sensor (S7) and the rear alignment plate home position sensor (S8).

[D] Stapling Operation

The stapling operation is to staple a specified number of paper with the stapler unit. The stapler unit is moved to the stapling position (the position differs depending on the paper size) by the stapler unit shift motor (M9). The home position of the stapler unit is detected by the stapler unit home position sensor (S10). The stapler interference switch (SW3) detects the no-operation area for the stapling operation and cuts off the power supply to the stapler while it is switched ON. The stapling operation is also stopped in the area where while the stapler interference sensor (S11) is turned ON to prevent the stapler from interfering with other mechanical sections in the equipment.

[E] Paper exiting operation

Bundles of the paper aligned or stapled on the finishing tray are then pulled up by the paper exit guide driven by the stack transport motor (M8) with the turning ON of the paper exit guide clutch (CLT2). Then the paper is exited by the paper exit belt driven by the stack transport motor (M8) and the stack transport rollers-1 and -2 driven by the transport motor (M2) onto the movable tray. The home position of the paper exit belt is detected by the stack exit belt home position sensor (S9).

The center-binding mode binds a stack of paper at its center by stapling at two positions and then folds in half again to exit it to the saddle tray. In this mode paper transported from the feeding section is stacked on the stacker. The stacks of paper are aligned on the stacker and moved to the stapling position together with the stacker. Then the moved stacks are fixed and stapled, and then moved to the folding position. Then they are folded with the folding blade and the folding roller. After this, the folded stacks are again folded and exited to the saddle tray.

[A] Saddle stitch feeding section

Paper transported from the junction box is then transported to the stacker with the transport roller, ejecting roller and assisting roller driven by the saddle transport motor (M16). The junction box paper detection sensor (S26), transport path-2 sensor (S27), transport path-3 sensor (S28) and ejecting roller sensor (S29) detect the passing of the paper. When the ejecting roller sensor (S29) detects that paper has passed, the assisting roller solenoid (SOL6) is turned ON to contact the assisting roller with the paper to transport it to the stacker.

The folding blade is pressed onto the center of the stack of paper stapled and moved to the folding position, and then the folding roller lets the stack of paper sandwich the blade so that the stack will be folded again. The folding blade clutch (CLT3) is turned ON to press the folding blade to the stack of paper by rotating the blade cam driven by the folding motor (M17). The rotation of the folding motor (M17) is detected by the folding motor encoder sensor (S34).
