MX-7500N  NOTE FOR SERVICING - ii
-  Place of direct sunlight.
Plastic parts and ink may be deformed, discolored, or may
undergo qualitative change.
It may cause a breakdown or output quality problems.
-  Place which is full of organic gases such as ammonium
The organic photo-conductor (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 and blue
print machine may result in poor quality output.
* There was a trouble in a place where silicon-series gas or vol-
atile components are generated. Use great care for avoiding
this.
-  Place of much dust
When dust or contaminants enters the machine, it may cause a
breakdown or poor quality output.
-  Place near a wall
The machine will require ventilation.
If ventilation is not proper, poor output or machine failure may
result.
-  Unstable or irregular surface
If the machine is dropped or tips over, it may cause injury or
machine malfunction.

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.
-  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 pro-
cedure on an anti-static mat.

Note for repairing/replacing the LSU
When repairing or replacing, be sure to observe the following
items.
-  When repairing or replacing the LSU, be sure to disconnect the
power plug from the power outlet.
-  When repairing or replacing the LSU, follow the procedures
described in this Service Manual.
-  When checking the operations after repairing the LSU, keep all
the parts including the cover installed and perform the operation
check.
-  Do not modify the LSU.
-  When visually checking the inside of the machine for the opera-
tion check, be careful not to allow laser beams to enter the eyes.
If the above precaution is neglected or the LSU is modified, ones
safety may be at risk.
6.
Note for handling the drum unit, the 
transfer unit, the developing unit
When handling the OPC drum unit, the transfer unit, and the devel-
oping unit, strictly observe the following items.
If these items are neglected, a problem may be generated in the
copy and print image quality.
Drum unit
-  Avoid working at a place with strong lights.
-  Do not expose the OPC drum to lights including interior lights for
a long time.
-  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.
Transfer unit
-  Be careful not to leave fingerprints, oil, grease, or other foreign
material on the transfer roller, primary transfer belt, and the sec-
ondary transfer belt.
Developing unit
-  Be careful not to leave fingerprints, oil, grease, or other foreign
material on the developing unit.
Fusing unit
-  Be careful not to attach finger prints or foreign materials on the
fusing belt and the pressure roller.

Screw tightening torque
The screws used in this machine are largely classified into three
types.
These types are classified according to the shape of the screw
grooves and use positions.
The table below shows the types of the screws and the tightening
torques depending on the use position.
When tightening the screws for repair or maintenance, refer to the
table.
However, for the other conditions of tightening screws than speci-
fied on this table, or under special circumstances, the details are
described on the separate page. Refer to the descriptions on such
an exception.
Especially for the screw fixing positions where there is an electrode
or a current flows, use enough care to tighten securely to avoid
loosening.
