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 specifications.
2. Be careful not to leave a switch, a cover or a safety device
out when reinstalling or assembling the product after
repair.
3. Replacing Precautions
Do not change or add parts as you like. You cannot benefit 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 specifications for the parts inflammable and where the current 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 components.
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. If you 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 static electricity.
1. Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a known
earth ground. Alternatively, employ a commercially available wrist strap device, which should be removed for your
personal safety reasons prior to applying power to the unit
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 prevent electrostatic charge buildup in the vicinity of the
assembly .
3. Use only a grounded tip soldering iron to solder or desolder ESDs.
4. Use only an “anti-static” solder removal device. Some solder 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 damage 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 comparable 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 completely plugged or soldered into the circuit.
9. Minimize bodily motions when handling unpackaged
replacement ESDs. Normal motions, such as the brushing together of clothing fabric and lifting one’s foot from a
carpeted floor, can generate static electricity sufficient to
damage an ESD.

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