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 oper-

ation 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, har-

nesses 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.

3. DESCRIPTION OF OPERATIONS

3.1 DRIVE SYSTEM

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 trans-

ported, compared to its rotational direction when they are being exited.

The read motor always rotates in a constant direction.

DESCRIPTION OF OPERATIONS

3 - 2

3.1.2 Original feed motor drive section

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 direc-

tion (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.

The transported original is driven by the read motor.

Then the original is transported to a scanning start position by the intermediate transfer roller and pre-

reading 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.

Fig. 3-4

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 origi-

nal 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 orig-

inal.

Sizes detectable in combination of these open and short of the signals are as follows:

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 cur-

rent 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 regard-

less 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).

DESCRIPTION OF OPERATIONS

3 - 17

3.4.2 Drive Circuit for Read Motor

Fig. 3-7

This circuit controls the rotation/stoppage and the direction of rotation, excitation mode and motor cur-

rent of the read motor.

A drive clock signal (RMOT-CLK) and rotation direction signal (RMOT-CW/CCW) are input to control

the speed and direction of the motor rotation.

When the level of the enabling signal (RMOT-Enable) is set to "L", motor current is turned to 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 (RMOT-Mode1/RMOT-Mode2).

The edge switching signal (RMOT-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

(RMOT-REF).

DESCRIPTION OF OPERATIONS

3 - 18

3.4.3 Drive Circuit for Exit Motor

Fig. 3-8

This circuit controls the rotation/stoppage and the direction of rotation, excitation mode and motor cur-

rent of the exit motor.

A drive clock signal (EMOT-CLK) and rotation direction signal (EMOT-CW/CCW) are input to control

the speed and direction of the motor rotation.

When the level of the enabling signal (EMOT-Enable) is set to "L", motor current is turned OFF regard-

less of the state of other signals.

As IC3-10pin (MODE1) is connected to +5V, excitation mode is applied at 1-2 phase excitation.

The edge switching signal (EMOT-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 switching the level of the reference switching signal

(EMOT-REFS0,EMOT-REFS1).

3.4.4 Drive Circuit for FAN Motor

Fig. 3-9

This circuit controls the rotation/stoppage of the fan motor. The FAN starts to rotate when the FAN

motor drive signal level is set to “H”, and stops when the level is set to “L”.

DESCRIPTION OF OPERATIONS

3 - 19

3.4.5 Reset Circuit

Fig. 3-10

This circuit generates a reset signal when the power is turned ON and the power voltage is blocked or

cut off/lowered temporarily.

At the power-ON, the circuit shifts the level of the reset signal from “L” to “H” to put the CPU in a opera-

tive state after the reset pulse duration (Tpd) determined by the capacitance of C58 has passed from

when the power voltage has reached the supervisory voltage (Vs) divided by R116 and R117.

When a power voltage drop (cutoff, temporary cutoff, temporary low voltage) occurs and the power volt-

age becomes lower than the set value for the supervisory voltage for the power, the circuit sets the level

of the reset signal (RESET) to “L” to put the CPU in a halt state.

3.4.6 Drive Circuit for Pickup Solenoid

Fig. 3-11

Pick up solenoid is a two-way solenoid that can be operated both in suction and recovery, and driven by

two transistors (Q4 and Q2) for each operation respectively.

When the PSOL-ON-Signal level is set to “L”, Q4 is turned ON, the power of 24V is applied to the coil

for suction operation, the solenoid is turned ON, and then the pickup roller goes down.

When the PSOL-ON-Signal level is set to “L”, Q2 is turned ON, the power of 24V is applied to the coil

for recovery operation, the solenoid is turned OFF, and then the pickup roller goes up.

DESCRIPTION OF OPERATIONS

3 - 20

3.4.7 Drive Circuit for Gate Solenoid

Fig. 3-12

Gate solenoid driven by the driver transistor (Q1) is a solenoid which is used to switch an original into

the reverse tray when in the duplex scanning mode.

When the GSOL-ON-Signal level is set to “L”, the reverse flap goes down and the original is trans-

ported to the reverse tray.

MAINTENANCE AND REWRITING ROM

7 - 2

7.2 Rewriting ROM (Firmware Updating)

It is feasible to update the firmware automatically by connecting the download jig to the PC board and

turning the power of the equipment ON. The download jig K-PWA-DLM-320 is used.

< Procedure >

(1) Turning OFF the power of the equipment and take off the RADF rear cover.

(2) Connect the download jig with the connector (CN81) on the PC board.

(3) While pressing [0] and [8] simultaneously, turn ON the power. (rewriting data starts)

(4) During the data is rewritten, the LED on the download jig lights. When the data rewriting is com-

pleted, the LED blinks slowly (at an interval of 0.8 sec.). If the LED blinks fast (at an interval of

0.1 sec.), the rewriting has been failed.

(5) Turn OFF the power of the equipment and remove the download jig.

(6) Install the RADF rear cover.

* If rewriting data is failed, turn OFF the power and repeat the procedure.
