NOTE FOR SERVICING
1. Precautions for servicing
1) When servicing, disconnect the power plug, the printer cable,
the network cable, and the telephone line from the machine,
except when performing the communication test, etc.
It may cause an injury or an electric shock.
2) There is a high temperature area inside the machine. Use
extreme care when servicing.
It may cause a burn.
3) There is a high voltage section inside the machine which may
cause an electric shock. Be careful when servicing.
4) Do not disassemble the laser unit. Do not insert a reflective
material such as a screwdriver in the laser beam path.
It may damage eyes by reflection of laser beams.
5) When servicing with the machine operating, be careful not to
place your hands by belts, gears, chains, and other drive com-
ponents.
6) Do not leave the machine with the cabinet disassembled.
Do not allow any person other than a serviceman to touch
inside the machine. It may cause an electric shock, a burn, or
an injury.
7) When servicing, do not breathe toner, developer, and ink
excessively. Do not get them in the eyes.
If toner, developer, or ink enters you eyes, wash it away with
water immediately, and consult a doctor if necessary.
8) The machine has got sharp edges inside. Be careful not to
damage fingers when servicing.
9) Do not throw toner or a toner cartridge in a fire. Otherwise,
toner may explode and burn you.
10) When replacing the lithium battery on the PWB, use only the
specified battery.
If a battery of different specification is used, the battery may
cause malfunction or breakdown of the machine.
11) When transporting a PWB, be sure to place the PWB in an
anti-static bag.
It may cause a breakdown or malfunctions.
2. Warning for servicing
1) Be sure to connect the power cord only to a power outlet that
meets the specified voltage and current requirements.
Avoid complex wiring, which may lead to a fire or an electric
shock.
2) If there is any abnormality such as a smoke or an abnormal
smell, interrupt the job and disconnect the power plug.
It may cause a fire or an electric shock.
3) Be sure to connect the grounding wire. If an electric leakage
occurs without grounding, a fire or an electric shock may
result.
For proper machine functionality, the machine must be
grounded.
4) When connecting the grounding wire, never connect it to the
following points.
It may cause an explosion, a fire or an electric shock.
- Gas tube
- Lightning conductor
- A water pipe or a water faucet, which is not recognized as a
grounding object by the authorities.
- Grounding wire for telephone line
5) Do not damage, break, or twist the power cord.
Do not put heavy objects on the power cable. Do not forcefully
bend or pull the power cable.
It may cause a fire or an electric shock.
6) Keep the power cable away from a heat source.
Do not insert the power plug with dust on it into a power outlet.
It may cause a fire or an electric shock.
7) Do not put a metallic object or a container with water in it inside
the machine.
It may cause a fire or an electric shock.
8) With wet or oily hands, do not touch the power plug, do not
perform servicing, touch the power plug, insert a telephone
jack, or operate the machine with wet or oily hands.
It may cause an electric shock.
3. Note for installing site
Do not install the machine at the following sites.
1) Place of high temperature, high humidity, low tempera-
ture, low humidity, place under an extreme change in tem-
perature and humidity.
Paper may get damp and form moisture inside the machine,
causing paper jam or copy dirt.
For operating condition, refer to the specifications described
later.
2) Place of much vibration
It may cause a breakdown.
3) Poorly ventilated place
An electro-static type copier will produce ozone inside it.
The quantity of ozone produced is designed to a low level so
as not to affect human bodies. However, continuous use of
such a machine may produce an odor of ozone. Install the
machine in a well ventilated place.
CAUTION
DOUBLE POLE/NEUTRAL FUSING
(200V series only)

MX-C250 NOTE FOR SERVICING - ii
4) Place of direct sunlight.
Plastic parts and toner may be deformed, discolored, or may
undergo qualitative change.
It may cause a breakdown or copy quality issues.
5) Place which is full of organic gases such as ammonium
The organic photoconductor (OPC) drum used in the machine
may undergo qualitative change due to organic gases such as
ammonium.
Installation of this machine near a diazo-type copier may result
in copy quality issues.
6) Place of much dust
When dusts enter the machine, it may cause a breakdown or
copy quality issues.
7) Place near a wall
Some machines require intake and exhaust of air.
If intake and exhaust of air are not properly performed, copy
dirt or a breakdown may be a result.
8) Unstable or slant surface
If the machine drops or falls down, it may cause an injury or a
breakdown.
If there are optional paper desks and the copier desks speci-
fied, it is recommendable to use them.
When using the optional desk, be sure to fix the adjuster and
lock the casters.
4. Note for handling PWB and electronic
parts
When handling the PWB and the electronic parts, be sure to
observe the following precautions in order to prevent against dam-
age by static electricity.
1) When in transit or storing, put the parts in an anti-static bag or
an anti-static case and do not touch them with bare hands.
2) When and after removing the parts from an anti-static bag
(case), use an earth band as shown below:
- Put an earth band to your arm, and connect it to the
machine.
- When repairing or replacing an electronic part, perform the
procedure on an anti-static mat.

5. Note for replacing the LSU
When replacing, be sure to observe the following items.
1) When replacing the LSU, be sure to disconnect the power plug
from the power outlet.
2) When replacing the LSU, follow the procedures described in
this Service Manual.
3) When checking the operations after repairing the LSU, keep all
the parts including the cover installed and perform the opera-
tion check.
4) Do not modify the LSU.
5) When visually checking the inside of the machine for the oper-
ation check, be careful not to allow laser beams to enter the
eyes.
If the above precaution is neglected or an undesignated work is
performed, safety may not be assured.
6. Note for handling the OPC drum unit, the
transfer unit, and the developer unit
When handling the OPC drum unit, the transfer unit, and the devel-
oper unit, strictly observe the following items.
If these items are neglected, a trouble may be generated in the
copy and print image quality.
(OPC drum)
1) Avoid working at a place with strong lights.
2) Do not expose the OPC drum to lights including interior lights
for a long time.
3) When the OPC drum is removed from the machine, cover it
with light blocking material. (When using paper, use about 10
sheets of paper to cover it.)
4) Be careful not to attach fingerprints, oil, grease, or other for-
eign material on the OPC drum surface.
(Transfer unit)
1) Be careful not to attach fingerprints, oil, grease, or other for-
eign material on the transfer belt and the transfer roller.
(Developer unit)
1) Be careful not to attach fingerprints, oil, grease, or other for-
eign material on the developer unit.

*1: Life of each color A4 5% coverage30% color ratio conversion value
(The ratio is a rough reference since it differs depending on print contents, paper seizes, kinds of paper, use environment, the number of
continuous prints.)
3. Definition of developer/drum life end
When the developer/drum counter reaches the specified count.
When the developer/drum rpm reaches the specified count.
When either of the above reach the specified count, it is judged as life end.
In an actual case, the ratio of monochrome output and color output may differ greatly.
When data of mixed documents (monochrome and color) are output, monochrome document data may be output in the color mode in order to
prevent against fall in the job efficiency. (ACS auto color selection).
In addition, when correction or warm-up operation is performed as well as output operation, the developer and the drum rotates.
Therefore, the developer/drum consuming level cannot be determined only by the copy/print quantity. When, therefore, the rpm reaches the
specified amount, it is judged as life end.
To check the developer/drum life, use SIM22-01.
