General Precautions for Installation/Servicing/Maintenance for the MJ-5002
The installation and service should be done by a qualified service technician.
1. When installing the MJ-5002 to the Plain Paper Copier , be sure to f ollow the instructions described in
the “Unpacking/Set-Up Procedure for the MJ-5002” booklet which comes with each unit of the
MJ-5002.
2. The MJ-5002 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 servcing or maintaining the MJ-5002, be careful about the rotating or operation sections such
as gear, pulleys, sprockets, cams, belts , etc.
5. When parts are disassembled, reassembly is basically the rev erse 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 .
6. Basically, the machine should not be operated with any parts removed or disassembled.
7. Delicate parts for preventing safety hazard problems (such as breakers, thermofuses, fuses, door
switches, sensors, etc. if any) should be handled/installed/adjusted correctly.
8. Use suitable measuring instruments and tools.
9. During servicing or maintenance wor k, 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.
10. 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.
11. For the recovery and disposal of used MJ-5002, consumable parts and packing materials, it is recommended that the relev ant local regulations/rules should be follo wed.
12. After completing installation, servicing and maintenance of the MJ-5002, retur n the MJ-5002 to its
original state, and check operation.

3. OPARATIONAL DESCRIPTION
3.1 General Operation
The OCT has a function to stack printed sheets of paper by putting them in the right and left stackers.
When fed to the OCT, printed paper can be stacked by putting it in the right or left stac k er . The offsetting
section is moved to the right or left by the motor.

OCT 03-02-01
Four detection switches , one solenoid, and one motor are connected to the OCT PWA. The motor drive
signals only go through the driver IC (IC1) and the other signals connect to the RELAY PWA as they are.
Those signals go through the RELAY PWA and connect to the MAIN PWA for control.
• At power-on time
At power-on time, the OCT checks the home position of the separ ate roller assemb ly through control
from the copier. If the sensor has not detected the home position at this time, the OCT motor is driven
to move the separate roller assembly to the home position.
• During offset operation
For offset stacking, the combination of the OFFSET1 and OFFSET2 signals allo ws the OCT motor to
operate and move the separate roller assemb ly to the right or left. If specified f or a size of paper which
cannot be offset, offset stacking will be ignored on the copier side.

Page 9
3.3 Detection of Abnormal Status
3.3.1 Cover open/Close detection
When the OCT cover open s witch detects the open state of the cov er , the copier detects it and stops the
transport of paper.
3.3.2 Paper jam detection
If the paper fed from the copier is jammed in the transport path, the OCT paper feed sensor detects
paper jamming. The signal is at “High” le v el while the paper is passing. If the “High” level time is too long,
the copier will judge it to be paper jamming.
3.3.3 Stacker full detection
When the stacker is full of paper , a stac ker full state is detected b y the OCT stack sensor . The stac ker full
state can be cleared by removing the paper from the stacker. This detection is effective only when the
OCT is operating so that no stacker full state occurs when the sensor is turned on while taking out the
paper from the stacker.

4.2 Paper Transport
For the transport path for paper, the paper coming out from the exit roller of the copier enters the OCT
and runs over the sensor , flap and separate roller assembly to the stac ker in this order as indicated b y the
arrow as shown in the figure above (solid line).
4.3 Flap Function
The flap is driven by the OCT solenoid. In duplex printing, the flap is lowered when one-side-printed
paper is fed. This allows the paper to be loaded into the copier again without catching on the roller (dotted
line).
The OCT exit sensor is located at the exit, which detects the limit number of sheets stacked. It detects
the stacker full state (approx. 39 mm, min. 250 sheets) when the number of sheets stacked increases to
raise the sensor arm.

To transport paper, driving force is delivered from

Flow of paper
OCT 04-04-01
OCT motor
copier is transmitted through the four gears to turn
the roller shaft and transport the paper.
The separator roller assembly is slid about 30 mm
right-to-left by the OCT motor . When using the offset stacking function, the separator roller is mov e d
right-to-left for every sheet or every set of sheets.
The OCT motor contains a brush motor and drives
the OCT motor arm right-to-left through the combination of gears, etc. The OCT motor arm is mov ed
right-to-left by the operation of the motor. The internal mechanism cuts the driving of the motor when
the arm moves 30 mm so that the arm will not move
beyond there or the motor will not be overloaded.
The flap is controlled by moving the arm connected
to the OCT solenoid. When the OCT solenoid turns
ON, the arm lowers to push down the flap.

The OCT PWA has the motor driver IC only and the other signals pass through the PWA.
IC1 is the motor driver IC and supplies 24V to the output side when the input signal turns ON. It outputs
24V at OFFSET-1 when OFFSET1 turns ON, and at OFFSET-2 when OFFSET2 turns ON. This changes
the rotational direction of the OCT motor to move the offset unit right-to-left.
JCONECT, F-SERECT, and JOB-SW each connect to GND. The JSP can be connected to the copier in
addition to the OCT. Those signals are used to identify the option connected. A combination of the signals
indicates the type of an option connected to the copier.

The OCT cover open switch detects the open or close state of the cover. A push switch is used for the
switch. The signal goes LOW when the cover is closed, and HIGH when it is open.
The OCT stack sensor detects the limit number of sheets stac ked. A photo sensor is used f or the sensor .
When the stacked number of sheets increases, the detection arm rises to turn on the sensor.
The OCT separate sensor detects the home position of the offsetting section. A photo sensor is used f or
the sensor. A certain position is detected when the offsetting section is moved b y driving the OCT motor .
The position becomes the home position (inner side).
The OCT paper feed sensor detects the presence or absence of paper in the transport path. A photo
sensor is used for the sensor. The signal goes HIGH while paper is passing over the sensor (paper
present), and LOW when no paper is present. If the paper present time (“High” level) does not change
even after a fixed time, paper jamming will be assumed.
The OCT motor moves the offsetting section right-to-left. A brush motor is used f or the motor . The motor
is driven according to the signals input to IC1. When either OFFSET1 or 2 input to IC1 turns ON, the
rotational direction of the motor changes to move the separate roller assembly to the right or left.
The OCT solenoid switches the transfer path to control the flap. The solenoid is usually OFF where the
paper passes the separate roller assembly bef ore being stac ked. In duplex printing, the flat lowers when
the OCT solenoid turns ON to prevent the one-side-printed paper from entering the separate roller
assembly so that the paper once stops at the upper transport path and is reversed and fed to the ADU.
After duplex printing, the paper is stacked as usual.
