5. 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 operation
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 develop-
ing unit, strictly observe the following items.
If these items are neglected, a trouble 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 second-
ary transfer roller.
Developing unit
• Be careful not to leave fingerprints, oil, grease, or other foreign
material on the developing unit.
7. 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 specified
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 loosen-
ing.
