7-1-4 Cleaning the Optical Parts
Carry out cleaning of the main unit and interior when replacing
the lamp or making inspections.
The glass cleaner used with the following parts is as follows.
a) Cleaning the Projection Lens:
*When dust and fingerprints, etc. are on the lens surface, use
the designated glass cleaner to remove as shown in the figure
at the right. For fingerprints and other soiling that are difficult
to remove with a dry cloth, use a designated glass cleaner
which has been moistened in water and then use a dry cloth
to dry it off.
*The projection lens surface has a special coating. Do not use
detergents or solvents on the surface.
b) Cleaning the DMD:
*The DMD surface is glass and can be cleaned. However, avoid
scratches as these can have a direct influence on the image.
*In case of dust on the DMD surface use an air cleaner ( with a
device to prevent static, if possible) to clean off the surface.
*In case of fingerprints, etc., add a small amount of water to the
designated glass cleaner and wipe off in one direction. Then
use the designated dry glass cleaner to wipe off in the same
direction.
*Do not use absolute alcohol or other substances that could
leave streaks after drying.
c) Cleaning the Reflecting Mirror:
*Be careful not to touch the reflecting mirror. The surface is
composed of vapor deposition silver and touching it directly
with the hands can lead to burnishing.
*Do not clean other than with air.
d) Cleaning the Main Unit:
*Clean with a soft fuzz-free cloth. In case of severe soiling, use
a well-wrung cloth dipped in a neutral agent to remove soiling
and then finish with a dry cloth.
*Do not clean with thinner, benzene or similar agents as this
could lead to deterioration or peeling of paint.
*In case of dust in suction or exhaust holes or the interior,
disassemble the main unit and use air to remove the dust from
the inside.
