This section describes maintenance tasks such as cleaning the projector and replacing consumable parts.
Cleaning the air filter
When dust builds up on the air filter, or the message 
“The projector is overheating. Make sure nothing is 
blocking the air vents, and clean or replace the air filter” 
is displayed, remove any dust from the air filter using a 
vaccum cleaner.
Cleaning the main unit
Cleaning the projection lens
Maintenance
If dust collects on the air filter, 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.
Clean the 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 the projectors surface. These can cause the projector 
to warp and make the coating finish peel off.
Use a commercially available air blower, or use a lens 
cleaning paper to gently wipe the lens.
Do not rub the lens with harsh materials or subject the lens to 
shocks, as it can easily become damaged.

Replace it with the optional air filter. s “Optional Accessories and Consumables” p. 60 
Lamp replacement period
•The message “Replace the lamp” appears on the screen when projection starts.
•The projected image gets darker or starts to deteriorate.
•In order to maintain the initial brightness and image quality, the lamp replacement message is displayed after about 1900 
hours of use has passed. The time at which this message is displayed will vary depending on the color mode settings and 
the conditions under which this unit has been used.
•If you continue to use the lamp after this period, the possibility of the lamp breaking becomes greater. When the lamp 
replacement message appears, replace the lamp with a new one as soon as possible, even if it is still working.
•Depending on the characteristics of the lamp and on the way it has been used, the lamp may become darker or stop 
working before the lamp warning message appears. You should always have a spare lamp ready in case it is needed.
•Contact your dealer for a spare lamp.
