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

If the air filter becomes blocked with dust and the message 
"The projector is overheating. Clean or replace the air filter 
and lower the room temperature" is displayed, clean the air 
filter.
Turn the projector upside-down and use a vacuum cleaner to 
clean the air filter.

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 the air filter becomes clogged with dust, it can result in 
overheating which may cause operating problems or 
reduce the operating life of the optical parts. It is 
recommended that you clean the air filter about once 
every three months. If using the projector in a dusty 
location, the air filter should be cleaned more often.

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.
