General Precautions for Installation/Servicing/Maintenance
for the MR-3018/3020/3021/3022
The installation and service shall be done by a qualified service technician.
1) When installing the MR-3018/3020/3021/3022 to the Equipment, be sure to follow the instructions
described in the “Unpacking/Set-Up Procedure for the MR-3018/3020/3021/3022” booklet which
comes with each unit of the MR-3018/3020/3021/3022.
2) The MR-3018/3020/3021/3022 should be installed by an authorized/qualified person.
3) The equipment must be grounded for safety.
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 easily accessible.
6) Be sure to fix and plug in the power cable securely after the installation so that no one trips over it.
7) 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.
8) The MR-3018/3020/3021/3022 should be grounded to the specified positions on the machine frame.
9) When servicing or maintaining the MR-3018/3020/3021/3022, be careful about the rotating or operation sections such as gears, pulleys, sprockets, cams, belts, etc.
10)Reassembly of disassembled parts is the reverse of the disassembly unless otherwise noted in this
manual or other related documents.
Care should be taken that small parts, such as screws, washers, pins, E-rings, star washers, harnesses are not installed in the wrong places.
11)Basically, the machine should not be operated with any parts removed or disassembled.
12)Delicate parts for preventing safety hazard problems (such as switches, sensors, etc. if any) should
be handled/installed/adjusted correctly.
13)Use suitable measuring instruments and tools.
14)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.
15)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 equipment and make sure that there is no uninsulated charged objects in
the vicinity.
16)For the recovery and disposal of used MR-3018/3020/3021/3022, consumable parts and packing
materials, follow the relevant local regulations/rules should be followed.
17)After completing installation, servicing and maintenance of the MR-3018/3020/3021/3022, return the
MR-3018/3020/3021/3022 to its original state, and check operation.

Fig. 3-1
3.1.1 Outline
Originals are transported by the original feed motor, read motor and original exit/reverse motor. Each
motor has a drive section for the following operations:
Original feed motor drive section: picks up originals and drives the registration roller.
Read motor drive section: transports originals and drives parts such as the pre-reading
roller.
Original exit/reverse motor drive section: exits and reverses originals, and drives the exit/reverse roller.
The Original feed motor rotates reversely when the originals are being transported at the registration
roller, compared to its rotational direction when they are being picked up.
The original exit/reverse motor also rotates reversely when the originals are being reversed and transported, compared to its rotational direction when they are being exited.
The read motor always rotates in a constant direction.

Fig. 3-2
When an original is placed on the original tray and the RADF receives a feed request signal from the
equipment, the feeding of the original is started.
The original empty sensor detects the presence of the original, and then the pickup roller is lowered by
the drive from the original pickup solenoid.
The Original feed motor rotates, and the pickup roller and the feed roller then rotate in a normal direction (shown in a solid line in the figure) to guide the original into the transport path. Then the original is
transported to the registration roller to be aligned.
The original aligned with the registration roller is then transported by the reverse rotation of the Original
feed motor (shown in a dotted line in the figure).
A one-way clutch is installed inside of each gear of the feed roller and the registration roller, so these
gears will not be driven in a reverse rotation.
When the original empty sensor detects that there is no original on the original tray, the original pickup
solenoid is turned OFF and the pickup roller is raised.
The original pickup solenoid is the one can operate both suction and recovery.

Then the original is transported to a scanning start position by the intermediate transfer roller and prereading roller.
The original transported to the scanning start position is then scanned in the scanner function of the
equipment.
When the data of the original have been scanned, the original is then transported to the original exit tray
side by the post-reading roller.

When the data of the original have been scanned, the original is exited to the original exit tray by the
exit/reverse roller driven by the exit motor (shown in a solid line in the figure).
In the duplex scanning mode, the gate solenoid is turned ON and the reverse flap is lowered to switch
the transport path to the reverse tray side when the scanning of one side of the original is completed.
When the reverse flap is lowered, the original is temporarily transported to the reverse tray, and then
the exit motor rotates reversely to return the original to the transport path switched for reverse operation
(shown in a dotted line in the figure).
The reversed original is aligned with the reverse registration roller, and then the other side of the original is scanned. When the scanning is completed, the original is exited to the original exit tray.

3.2 Original Size Detection
The original tray width sensor, original length detection sensor, and original width detection sensors-1
and -2 work in combination to detect the size of originals.

Fig. 3-5
3.2.1 Outline
When an original is placed on the original tray, the width of the original is detected by the positions of
the original width guides. Then the original width sensors -1 and -2 and the original length detection
sensor detect the size of the original being transported. Based on the detection result of these sensors,
the size of the original is finally determined.
3.2.2 Original tray width sensor
The original tray width sensor detects the width of an original placed on the original tray.
It is detected by the brush attached to the rack moving on the original tray width sensor, which is a
board with the different length of the patterns written.
This brush is moved as the original width guide is moved. Signals (TWID0S, TWID1S, TWID2S) are
opened and shorted to SG by this movement.
The combination of these short (= low level) and open (= high level) can determine the width of the original.
Sizes detectable in combination of these open and short of the signals are as follows:

DESCRIPTION OF OPERATIONS
3.4 DESCRIPTION OF CIRCUIT
3.4.1 Drive Circuit for Feed Motor
Fig. 3-6
This circuit controls the rotation/stoppage and the direction of rotation, excitation mode and motor current of the feed motor.
A drive clock signal (FMOT-CLK) and rotation direction signal (FMOT-CW/CCW
) are input to control the
speed and direction of the motor rotation.
When the level of the enabling signal (FMOT-Enable) is set to "L", motor current is turned OFF regardless of the state of other signals.
For the excitation mode, either of 2 phase excitation, 1-2 phase excitation, W1-2 phase excitation,
2W1-2 phase excitation or the 4W1-2 phase excitation can be selected using the excitation switching
signal (FMOT-Mode1/FMOT-Mode2).
The edge switching signal (FMOT-Mode3) is used to specify the switching timing for excitation phase
either from when both the rise and decay edge of the CLK input are detected or when only the rising
edge is detected.
Motor current value can be set discretionary by changing the level of the reference setting signal
(FMOT-REF).
