Precautions; Disassembly And Reassembly - Muratec F-110 Field Engineering Manual

1. Precautions

Please read the following carefully to prevent any accidents and not to damage the unit during service.
1-1 Safety Precautions
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.
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 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.
1-2 Precautions on Disassembly and Reassembly
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.
