Cleaning
Cleaning with air spray
Remove the cabinet top following to “ Mechanical Disassembly”. Clean up the LCD panel and polarizing plate by
using the air spray from the cabinet top opening.
Caution:
Use a commercial (inert gas) air spray designed for cleaning camera and computer equipment. Use a resin-based
nozzle only. Be very careful not to damage optical parts with the nozzle tip. Never use any kind of cleanser on the
unit. Also, never use abrasive materials on the unit as this may cause irreparable damage.
Disassembly Cleaning
Disassembly cleaning method should only be performed when the unit is considerable dirty and cannot be
sufficiently cleaned by air spraying alone.
Be sure to readjust the optical system after performing disassembly cleaning.
1. Remove the cabinet top and main units following to “ Mechanical Disassembly”.
2. Remove the optical base top following to “Optical Unit Disassembly”. If the LCD panel needs cleaning, remove
the LCD panel unit following to “ LCD panel replacement”.
3. Clean the optical parts with a soft cloth. Clean extremely dirty areas using a cloth moistened with alcohol.
Caution:
The surface of the optical components consists of multiple dielectric layers with varying degrees of refraction.
Never use organic solvents (thinner, etc.) or any kind of cleanser on these components.
Since the LCD panel is equipped with an electronic circuit, never use any liquids (water, etc.) to clean the unit. Use
of liquid may cause the unit to malfunction.
After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized
glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit.
Remove dust and other particles using air spray. If dirt cannot be removed by air spray, disassemble and clean
the optical unit.
Cleaning the Projector Cabinet
Cleaning the Projection Lens
Unplug the AC power cord before cleaning.
Gently wipe the projection lens with a cleaning cloth that
contains a small amount of non-abrasive camera lens
cleaner or use a lens cleaning paper or commercially
available air blower to clean the lens.
Avoid using an excessive amount of cleaner. Abrasive
cleaners, solvents or other harsh chemicals might scratch
the surface of the lens.
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning
cloth. When the cabinet is heavily soiled, use a small
amount of mild detergent and finish with a soft dry cleaning
cloth. Avoid using an excessive amount of cleaner. Abrasive
cleaners, solvents or other harsh chemicals might scratch
the surface of the cabinet.
When the projector is not in use, put the projector in
an appropriate carrying case to protect it from dust and
scratches.
