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 air filter and air intake vent

If the air filter or air intake vent becomes blocked with dust, the
message "The projector is overheating. Clean or replace the air
filter and lower the room temperature" will be displayed and you
must clean the filter or vent.
To do so turn the projector upside-down and use a vacuum cleaner.

Cleaning the projector case

Clean the projector case 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 case. Then
wipe the case again with a soft, dry cloth.

Cleaning the lens

Use a commercially-available air blower, or use a lens cleaning
paper to gently wipe the lens.

Be sure to read the separate Safety Instructions/World-Wide Warranty Terms booklet for
details on safe handling of the projector during cleaning.
If dust collects on the air filter or the air intake vent,
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.
Do not use volatile substances such as wax,
alcohol or thinner to clean the projector case.
These can cause the case to warp and make the
coating finish peel off.
Do not rub the lens with harsh materials or subject
the lens to shocks, as it can easily become
damaged.
