1. Precautions

Please read the following carefully to prevent any accidents and not to damage the unit during service.

1-1 Safety Precautions

1-2 Precautions on Disassembly and Reassembly

1. Safety Precautions

There are some electric or machinery parts with safety

related property. If the parts replaced are different from

the original, the safety may not function. Even if the part

could allow higher voltage than that of the part used, do

not replace it and use a regular product clarified in spec-

ifications.

out when reinstalling or assembling the product after

repair.

3. Replacing Precautions

Do not change or add parts as you like. You cannot ben-

efit from such a remodeled product at your will during the

term of guarantee.

4. You must replace overheated or damaged parts or cords

with regular products. Please solve the problem causing

any damage or overheating and troubles beforehand.

Especially mind the safety on the part with this

mark.

You must use regular parts described in specifica-

tions for the parts inflammable and where the cur-

rent can be flown. Otherwise any hazard such as

an electric shock or a fire could occur.

Very careful precautions should be taken when replacing

parts. Before replacing, please check cables because you

cannot put the cables that you removed for replacing parts

into the proper place if you would not make sure of where

they were connected and in which condition.

Please do the following before disassembling

for a repair or replacement of parts.

1. Pull out paper cassette, printer cartridge installed.

Especially careful not to be scratched by the surface of

developer or not to expose them to light.

2. Turn the power switch off.

3. Take out the power plug, printer cable from the printer.

4. Use only the same type of part as original when replacing

parts.

5. Do not force to open or fasten plastic material compo-

nents.

6. Be careful that small parts such as screws should not get

in the printer.

7. When disassembling, assembling, also observe small

components are located in place.

8. Ifyou uncover and turn the machine over to replace some

parts, toner or paper particles may contaminate the LSU

window. Protect the LSU window with clean paper.

Releasing Plastic Latches

Many of parts are held in

place with plastic latches.

The latches break easily :

release them carefully.

To remove such parts, press

the hook end of the latch

away from the part to which

it is latched.

Certain semiconductor devices can be easily damaged by

static electricity. Such components are commonly called

“Electrostatically Sensitive (ES) Devices”, or ESDs.

Examples of typical ESDs are: integrated circuits, some field

effect transistors, and semiconductor “chip” components.

The techniques outlined below should be followed to help

reduce the incidence of component damage caused by sta-

tic electricity.

1. Immediately before handling a semiconductor compo-

nent or semiconductor-equipped assembly, drain off any

electrostatic charge on your body by touching a known

earth ground. Alternatively, employ a commercially avail-

able wrist strap device, which should be removed for your

personalsafetyreasonspriortoapplyingpowertotheunit

under test.

2. After removing an electrical assembly equipped with

ESDs, place the assembly on a conductive surface, such

as aluminum or copper foil, or conductive foam, to pre-

vent electrostatic charge buildup in the vicinity of the

assembly.

3. Use only a grounded tip soldering iron to solder or desol-

der ESDs.

4. Use only an “anti-static” solder removal device. Some sol-

der removal devices not classified as “anti-static” can

generate electrical charges sufficient to damage ESDs.

5. Do not use Freon-propelled chemicals. When sprayed,

these can generate electrical charges sufficient to dam-

age ESDs.

6. Do not remove a replacement ESD from its protective

packaging until immediately before installing it. Most

replacement ESDs are packaged with all leads shorted

together by conductive foam, aluminum foil, or a compa-

rable conductive material.

7. Immediately before removing the protective shorting

material from the leads of a replacement ESD, touch the

protective material to the chassis or circuit assembly into

which the device will be installed.

8. Maintain continuous electrical contact between the ESD

and the assembly into which it will be installed, until com-

pletely plugged or soldered into the circuit.

9. Minimize bodily motions when handling unpackaged

replacement ESDs. Normal motions, such as the brush-

ing together of clothing fabric and lifting one’s foot from a

carpeted floor, can generate static electricity sufficient to

damage an ESD.

3. Disassembly and Reassembly

3-1 General Precautions on Disassembly

When you disassemble and reassemble components, you

must use extreme caution.

The close proximity of cables to moving parts makes proper

routing a must. If components are removed or replaced, any

cables disturbed by the procedure must be replaced as close

as possible to their original positions.

Before removing any component from the machine, note the

cable routing that will be affected.

Whenever servicing the machine, you must perform as fol-

lows:

1. Check to verify that documents are not stored in memory.

2. Unplug the power cord.

3. Use a flat and clean surface.

4. Replace only with authorized components.

5. Do not force to remove or planten plastic-material compo-

nents.

6. Make sure all components are in their proper position.

3-2 Scanner Ass'y

1. Remove two screws securing the rear cover.

2. Open the front door from the main cover.

3. Remove two screws securing the main cover.

4. Pull the scanner ass'y upward then, unplug the two

connectors and CCD cable.

Note :

You should connect or remove the CCD cable verti-

cally to avoid the CCD cable pin damage.
