Maintaining the Projector 
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 here or in the User’s Guide. Refer all other 
servicing to qualified service personnel.
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 a commercially 
available cloth for cleaning glasses.
Caution: Do not spray liquid or glass cleaner directly on the lens.
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 water and 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 and protect your investment. 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, 
which can 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).
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 
PPower 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 meters), 
turn on High Altitude Mode in the 
Operation menu. Do not use the projector 
above 7,500 feet (2,286 meters).
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.
Flashing

3. If the dirt is difficult to remove or the filter is broken, 
replace the filter as described below. Contact your dealer or 
call Epson at 800-GO-EPSON (800-463-7766) to obtain a 
new filter (part number V13H134A08). 
Replacing the Lamp and Air Filter
The life span of the projection lamp is about 2,500 hours if 
Brightness Control in the Settings menu is set to High 
(default), and 3,000 hours if 
Brightness Control is set to Low.
Note: When you get a replacement lamp for your projector, you 
should replace the filter. Turn off this product when not in use to 
prolong the life of the projector.
It is time to replace the lamp when: 
❏The projected image gets darker or starts to deteriorate.
❏The message 
Replace the lamp appears on the screen when 
the lamp comes on and the lamp warning light   flashes 
orange. To maintain projector brightness and image quality, 
replace the lamp as soon as possible. 
❏The lamp warning light   flashes red (the lamp is burnt 
out).
To obtain a new lamp, contact your dealer or call Epson at 
800-GO-EPSON (800-463-7766). Request part number 
V13H010L40. Follow these steps to replace the lamp and air filter:
1. Turn off the projector and unplug the power cord.
2. Let the projector cool for at least an hour (if it has been on). 
The lamp is extremely hot immediately after use. 
Warning: Let the lamp cool fully before replacing it. In the 
unlikely event that the lamp has broken, small glass fragments 
may be present and should be removed carefully to avoid injury. 
If the lamp is used after the replacement period has passed, the 
possibility that the lamp may break increases. When a lamp 
replacement message appears, replace the lamp with a new one 
as soon as possible, even if it is still working.

the lamp cover to the side and lift it off the projector.
