code number that appears in the Password Protect Release screen for 
assistance. See “Where To Get Help” on page 76.

Maintaining the Projector
Your projector needs little maintenance. All you have to do is keep 
the lens clean and periodically clean the air filter and vent. A clogged 
air filter or vent 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 filter and vent
■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. 
						

							58Maintaining 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 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.
caution
Do not use wax, alcohol, 
benzene, paint thinner, or 
other chemical detergents. 
These can damage the case. 
						

							Maintaining the Projector59
Cleaning the Air Filter and Vent
Clean the air filter and air intake vent 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 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).
4. If the dirt is difficult to remove or the filter is broken, replace the 
filter as described on page 62. Contact your dealer or call Epson at 
800-GO-EPSON (800-463-7766) to obtain a new filter. 
note
To order replacement air 
filters, request part number 
V13H13408. See page 11 
for ordering information. 
						

							60Maintaining the Projector
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 
(800-463-7766). Request part number V13H010L38. 
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 filter.
To check how long the lamp 
has been in use, see page 69.
Turn off this product when 
not in use to prolong the life 
of the projector. 
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.
