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 surface.
Caution: Do not use glass cleaner to clean the lens.
Cleaning the Projector 
Before you clean the case, first 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, moisten a soft cloth with 
water and a mild detergent. Then wipe the case. 
❏ Do not use wax, alcohol, benzene, paint thinner, or other 
chemical detergents. These can damage the case.
Cleaning the Air Filters and Vents
Clean the air filters and air intake vents after every 100 hours 
of use. If they are not cleaned periodically, they can become 
clogged with dust, preventing proper ventilation. This 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 vents, EPSON recommends using a 
small vacuum cleaner designed for computers and other 
office equipment. If you don’t have one, gently clean the 
vents with a soft brush (such as an artist’s paintbrush).
3. Gently turn the projector over and remove the filters from 
the side and bottom of the projector. Then use a small 
vacuum cleaner or soft brush to clean the two filters. Slide 
the filters back into place when you’re done.
4. If the dirt is difficult to remove or a filter is broken, replace 
the filters as described below. Contact your dealer or call 
EPSON at (800) 873-7766 in the United States to obtain 
new ones. In Canada, please call (800) 463-7766 for dealer 
referral.
Replacing the Lamp and Air Filters
The life span of the projection lamp is about 2000 hours. It is 
time to replace the lamp when: 
❏ The projected image gets darker or starts to deteriorate.
❏ The message 
LAMP REPLACE
 appears on the screen when 
the lamp comes on (after about 1900 hours) and the 
lamp warning light is flashing orange. To maintain 
projector brightness and image quality, replace the lamp as 
soon as possible. 
❏ The 
 lamp warning light is flashing red (the lamp is 
burnt out).
Contact your dealer or call EPSON at (800) 873-7766 in the 
United States for a replacement lamp. Request part number 
V13H010L22. In Canada, please call (800) 463-7766 for 
dealer referral.
Note: When you get a replacement lamp for your projector, new 
air filters are included. You should replace the filters when you 
replace the lamp. You can check how long the lamp has been in 
use (see page 20).
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.
