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.

2.6 Description of Interface Signals

TxD

RxD

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.

• Bundle job offset mode/ stapling stack mode When the sort copying and the stapling function are set, paper exits in the procedure shown below. 1 Paper is transported to the buffer tray. 2 Paper is dropped from the buffer tray onto the finishing tray. 3 Paper stucked on the finishing tray is aligned and stapled, and then the bundled paper is output

to the movable tray.

DESCRIPTION OF OPERATIONS

• Center-binding mode Paper is exited following the procedure below when the Saddle Stitch Finisher is installed. 1 The stacker is moved to the stapling position according to the detected paper size. 2 Paper is transported to the stacker and then side alignment operation is performed. 3 The stack of paper is stapled after the alignment for the last page is finished. 4 The stacker is moved to the paper folding position to fold the paper. 5 The paper is transported to the additional folding position to be folded again. 6 The paper is exited to the saddle tray.
