General Precautions for Installation/Servicing/Maintenance for the MR-2018/2019 and MY-1034

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

1. When installing the MR-2018/2019 and MY-1034 to the Equipment, be sure to follow the instructions described in the "Unpacking/Set-Up Procedure for the MR-2018/2019 and MY-1034" booklet which comes with each unit of the MR-2018/2019 and MY-1034.

2. The MR-2016/3017 should be installed by an authorized/qualified person.

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

4. When servicing or maintaining the MR-2018/2019 and MY-1034, be careful about the rotating or operation sections such as gears, pulleys, sprockets, cams, belts, etc.

5. 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 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 switches, sensors, etc. if any) should be handled/installed/adjusted correctly.

8. Use suitable measuring instruments and tools.

9. 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.

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 equipment and make sure that there is no uninsulated charged objects in the vicinity.

11.For the recovery and disposal of used MR-2018/2019 and MY-1034, consumable parts and packing materials, follow the relevant local regulations or rules.

12.After completing installation, servicing and maintenance of the MR-2018/2019 and MY-1034, return the MR-2018/2019 and MY-1034 to its original state, and check operation.

2. RADF/ADF open/close detection

(book document detection)

RADF/ADF open/close detection (book document) detection is performed by detecting the interval between the reference lines on the white Mylar attached to the paper exit guide (document scanning section) by the scanner (CCD) and detecting the varied quantity.

Reference line Reference line

Note: When replacing the carriage unit, be sure to execute SIM41-

06. If SIM41-06 is not executed, the carriage unit may not read

the reference line on the white Mylar, preventing the document from being fed.

* When installing, fit the cut surface A.

F. 2nd paper feed roller

1) Remove the E-ring and the parts.

2) Remove the 2nd paper feed roller.

* When installing, hang the 2nd connection arm on the 2nd con-

nection arm Spring B. Be sure to install so that the earth spring C is in contact under the bearing D.

G. Paper width sensor

1) Insert the connector into the tray detect switch, and attach the tray detect switch to the paper feeding frame.

2) Attach the 2nd actuator spring to the actuator lever, and fix it together with the washer and the screw.

3) Check to confirm that the hook section of the 2nd actuator spring is inserted into section A of the paper feeding frame.

After completion of assembly, check to confirm that the actuator lever rotes in the arrow direction.

[6] ADJUSTMENTS

1. ADF/RADF scan position automatic

adjustment

Place a A4 paper (white chart) so that it covers the ADF scan glass and the OC glass together, and close the ADF/RADF.

When simulation 53-08 is executed, the current adjustment value is displayed as the initial display.

* Default is 1. Adjustment range is 1 – 99. Adjustment unit 1 =

about 0.127mm

* If the values are kept as the default values, ADF/RADF scan is

not performed properly. The front area of the proper scan position may be scanned.

In case of AUTO, press [START] key, and the mirror unit scans from the home position to the ADF/RADF scan position with the adjustment value displayed. The ADF glass cover edge position is calculated from the difference between the ADF glass cover edge and the OC side document glass CCD output level. If the adjustment is normal, the adjusted value is displayed. If abnormal, the error LED lights up with the current set value displayed.

During the error LED is lighted, when [ST AR T] k e y is pressed again, execution is performed again.

2. ADF/RADF mode sub scanning direction magnification ratio adjustment

Note : Before performing this adjustment, be sure to check that the

OC mode adjustment in copying has been completed.

1) Put a scale on the original table as shown below, and make a

normal copy (100%) on the front and the back surfaces to make a test chart.

Note : Since the printed copy is used as a test char t, put the scale

in paralled with the edge lines.

2) Set the test chart on the ADF and make a copy in the normal

ratio (100%). (ADF model only) Set the test chart on the RADF and make a duplex copy (D-D or

D-S) in the normal ratio (100%). (RADF model only)

3) Compare the scale image and the actual image.

If necessary, perform the following adjustment procedures.

4) Execute SIM 48-05.

5) The current sub scanning direction magnification ratio correc-

tion value is displayed in two digits on the display section.

6) Enter the set value and press the [START] key.

When adjusting the RADF, use [2-SIDED COPY] key to select single/duplex after entering the one page print mode, performing 2-page single copy.

LEAD-FREE SOLDER

The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder. The alphabet following the LF mark shows the kind of lead-free solder.

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD

When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a breakdown or an accident. Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use

soldering iron is recommendable.

Solder composition code

(2) NOTE FOR SOLDERING WORK

Since the melting point of lead-free solder is about 2 20°C, which is about 40°C higher than that of conventional lead solder, and its soldering capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when completion of soldering is confirmed.

Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently. If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip after

completion of soldering work. If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
