Cleaning

Maintenance
This section describes maintenance tasks such as cleaning the projector and
replacing consumable parts.
Cleaning
You should clean the projector if it becomes dirty or if the quality of projected
images starts to deteriorate.

Cleaning the Projector

Clean the projector's surface by wiping it gently with a soft cloth.
If the projector is particularly dirty, moisten the cloth with water containing a
small amount of neutral detergent, and then firmly wring the cloth dry before
using it to wipe the projector's surface. Then wipe it again with a soft, dry
cloth.
Do not use volatile substances such as wax, alcohol or thinner to clean
c
the projector's surface. These can cause the projector to warp and make
the coating finish peel off.

Cleaning the Lens

Use a commercially-available air blower, or use a lens cleaning paper to
gently wipe the lens.
c
Do not rub the lens with harsh materials or subject the lens to shocks, as
it can easily become damaged.

Cleaning the Air Filters and Air Intake Vent

If dust collects on the air filter or the air outlet, it can cause the internal
temperature of the projector to rise, and this can lead to problems with
operation and shortening of the optical engine's service life.
It is recommended that you clean these parts at least once every three
months. Clean them more often than this if using the projector in particularly
dusty environments.
If the air filters are broken or if the warning message reappears after
p
they have been cleaned, they should be replaced. Replace with a new air
filter. See "Replacing the Air Filter" on page
