Maintaining the Projector 
Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface.
❏ Use a canister of compressed air to remove dust.
❏ To remove dirt or smears on the lens, use lens-cleaning 
paper. If necessary, moisten a soft cloth with lens cleaner and 
gently wipe the lens.
Warning: Before you clean any part of the projector, turn it off and 
unplug the cord. Never open any cover on the projector, except the 
lamp cover. Dangerous electrical voltages in the projector can injure 
you severely. Do not try to service this product yourself, except as 
specifically explained in this manual or the User’s Guide. Refer all 
other servicing to qualified service personnel.
Cleaning the Projector Case
Before you clean the case, turn off the projector and unplug the 
power cord.
❏ To remove dirt or dust, wipe the case with a soft, dry, 
lint-free cloth.
❏ To remove stubborn dirt or stains, wipe the case with a soft 
cloth moistened with a mild detergent.
Caution: Do not use wax, alcohol, benzene, paint thinner, or other 
chemical detergents. These can damage the case.
Cleaning the Air Filter and Vent
Your projector includes an air filter to ensure the best 
performance. If dust collects on the air filter (on the bottom of 
the projector) or vent (on the front of the projector), clean them 
as described below. Dust clogs prevent proper ventilation and 
can cause overheating and damage the projector. Follow these 
steps:
1. Turn off the projector and unplug the power cord.
2. To clean the intake vent and filter, use a small vacuum 
cleaner designed for computers and other office equipment. 
If you don’t have one, gently clean the vent with a soft brush 
(such as an artist’s paintbrush).
You can remove the air filter to clean both sides.
3. If the dirt is difficult to remove or the filter is broken, replace 
the filter.
Red The projector is overheating, which turns 
the lamp off automatically. Wait until the 
cooling fan stops, then unplug the power 
cord. Plug the cord back in and press the 
P Power button. Make sure the room 
temperature is not above 95 °F (35 °C), 
and there is plenty of space around and 
under the projector for ventilation.
If you’re using the projector above an 
altitude of 5,000 feet (1,500 m), 
turn on 
High Altitude Mode in the 
Operation menu.
The air filter or vents may be clogged. 
Clean them or replace the air filter. If the 
projector continues to overheat after you 
clean the air filter, the problem may be 
caused by damage to the cooling fan or 
temperature sensor. Contact Epson for 
help.
