MX-265N

Service Manual

 

* About a main unit illustration, it may differ from a target model.

Before installing the machine, check that the following installing
(use) conditions are satisfied.

If the installing (use) conditions are not satisfied, the machine may
not display full performances, resulting in troubles. It may also
cause safety problems. Therefore, be sure to arrange the installing
(use) conditions before setting up the machine.

For installation of a large size machine, be sure to check that the
door size is wide enough before bringing in.

The following space must be provided around the machine in order
to assure machine performances and proper operations.

If any option is installed, provide the additional space for installing
it.

Adequate space must be provide behind the machine for proper
ventilation heat and dust. If not, the machine cannot exhibit func-
tions against heat and dust, causing some troubles.

If the power specifications are not satisfied, the machine cannot
exhibit full performances and may cause safety trouble.

Strictly observe the following specifications.

Check that the following power capacity is satisfied. If not, addition-
ally provide a power source.

Japan: 20A or more

EX 100V: 15A or more

EX 200V: 10A or more

NOTE: Check the shape of the power plug of the machine, and

insert it into a power outlet of the acceptable shape.

Measure the voltage during copying to check that the voltage is in
the range of the specified voltage 

If the voltage is outside the specified range, please have a certified
electrician upgrade the outlet.

(An electrical work is required.)

Use of a step-up transformer is also available. In this case, the
capacity must be great enough for the max. power consumption of
the machine.

The frequency must be within the range of the specified frequency

Be sure to properly ground the machine.

Grounding (earth connection) must be performed before inserting
the power plug into the power outlet.

When disconnecting the earth connection, be sure to disconnect
the power plug from the power outlet in advance.

Check the shape of the power plug of the machine, and insert it into
a power outlet of the acceptable shape.
Power plug stated in power capacity.

This machine is considerably heavy and becomes heavier with an
option installed.

The floor must be strong enough to safely support the weight of the
machine as well as any installed options.

If the unit is not horizontally installed, the toner density control is not
performed normally, degrading the copy quality.

If not, color shift or image distortion may occur.
To assure proper Image quality, make sure the machine is setting
level.

This machine is designed to perform properly under the specified
temperature and humidity. If the temperature and humidity exceeds
the specified range, the machine may not operate properly and or
cause equipment failure.

Especially when the humidity is too high, paper absorbs humidity to
cause a paper jam or dirty copy.

Do not install the machine near a heater, a cooler, or a humidifier.

Condensation may form inside the machine causing multiple trou-
bles. Use enough care for ventilation.

Temperature: 10 to 35

Humidity: 20 to 85% RH

Atmospheric pressure: 590 to 1013hPa (altitude: 0 to 2000 m)

If dust enters the machine, it may cause dirty copy and a paper
jam, resulting in a shortened lifetime.

If the machine is installed under the rays of the sun, the exterior of
the machine may be discolored and abnormal copies may be pro-
duced.

Do not install the machine at a place where there are gases and
chemicals. Especially be careful to avoid installation near a diazo-
type copier, which produces ammonium gas.

Copy quality may be adversely affected and a trouble may be
caused.

Avoid installation near a machine which produces vibrations.

If vibrations are applied to the copier machine, copy images may be
deflected and a trouble may be caused.

MX-265N  Transit, Installation (using) environment, Note   - ii

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.

• 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.

• 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.

When handling the OPC drum and developing units, observe the
following items.

• To prevent  damage to the OPC drum, avoid working on the drum

unit in high intensity light areas.

• 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.)

• Be careful not to attach fingerprints, oil, grease, or other foreign

material on the OPC drum surface.

• Be careful not to "leave” fingerprints, oil, grease, or other foreign

material on the developing unit.

• Be careful not to "leave” fingerprints, oil, grease, or other foreign

material on the fusing roller.

If these items are neglected, a trouble may be generated in the
copy and print image quality.

It is recommendable to use a forklift for bringing in the machine for
safety.

If no forklift is available, man-power of two persons is required. The
machine is considerably heavy, and requires safety precautions for
delivery and installation.

Transit of the machine must be made in packed condition to the
installing place.

Use care not to exert vibrations or shocks to the machine when in
transit.

Remove the packing materials prior to installation in the office envi-
ronment.
