Maintaining the Projector
Your projector needs little maintenance. All you have to do is keep 
the lens clean and periodically clean the air filters at the side and 
bottom of the projector. A clogged air filter can block ventilation 
needed to cool the projector.
The only parts you should replace are the lamp and air filter. If any 
other part needs replacing, contact your dealer or a qualified servicer.
This chapter covers the following:
■Cleaning the lens
■Cleaning the projector case
■Cleaning the air filters and vents
■Replacing the lamp and air filter
■Transporting the projector
warning
Before you clean any part of 
the projector, turn it off and 
unplug the power 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 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 lens-cleaning tissue. If 
necessary, moisten a soft cloth with lens cleaner and gently wipe 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, moisten a soft cloth with water 
and a neutral detergent. Then wipe the case.
Remove the cap 
before cleaning
caution
Do not use wax, alcohol, 
benzene, 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. Wait for the 
Power light to stop flashing, 
then unplug the power cord.
2. Turn the projector upside down.
3. To clean the intake vents, use 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).
4. If the dirt is difficult to remove or the filter is broken, replace the 
filter as described on page 148. Contact your dealer or call Epson 
at 800-GO-EPSON (800-873-7766) to obtain a new filter. 
note
To order replacement air 
filters, request part number 
V13H134A08. See page 13 
for ordering information.

Replacing the Lamp and Air Filter
The life span of the projection lamp is about 2000 hours if 
Brightness Control in the Setting menu is set to High (default), and 
3000 hours if 
Brightness Control is set to Low. 
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).
Contact your dealer or call Epson at 800-GO-EPSON 
(800-873-7766). Request part number V13H010L32. 
Follow these steps to replace the lamp and air filter:
1. Turn off the projector.
2. When the 
Power light stops flashing, unplug the power cord.
3. Let the projector cool for at least an hour (if it has been on). The 
lamp is extremely hot immediately after use. 
note
When you get a replacement 
lamp for your projector, you 
should replace the filters.
To check how long the lamp 
has been in use, see 
page 155.
warning
Let the lamp cool fully 
before replacing it.

the lamp has broken, small 
glass fragments may be 
present and should be 
removed carefully to avoid 
injury.

Transporting the Projector
The projector contains many glass and precision parts. Follow these 
guidelines to prevent damage:
■When shipping the projector for repairs, use the original 
packaging material if possible. If you do not have the original 
packaging, use equivalent materials, placing plenty of cushioning 
around the projector.
■When transporting the projector a long distance, first place it in a 
hard-shell shipping case, then pack it in a firm box with 
cushioning around the case. (An optional case is available from 
Epson; see page 13.)note
Epson shall not be liable for 
any damages incurred 
during transportation.
