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.

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.

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

If the air filters become clogged with dust, or if the message "The projector 
is overheating. Clean or replace the air filter and lower the room 
temperature." appears on the screen, clean the air filters and the air intake 
vent.
If the air filters become clogged with dust, it can cause overheating and 
damage the projector.
Turn the projector upside-down and use a vacuum cleaner to clean the air 
intake vent.

Cleaning the Projector Case

Cleaning the Lens

CAUTION

Be sure to read the separate Safety Instructions/World-Wide Warranty 
Terms before cleaning.

CAUTION

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.

CAUTION

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

TIP

• If the air filters are broken or if the warning message reappears after 

they have been cleaned, they should be replaced. Replace with a new 
air filter. See "Appendices: Optional Accessories".

• Spare lamps are provided with a spare air filter. The air filter should 

also be replaced when the lamp is replaced.
