Maintenance
Your projector needs little maintenance. You should keep the 
lens clean because any dirt or smears appear on the screen. 
You also need to periodically clean the air filter at the bottom 
of the projector. A clogged air filter can block ventilation 
needed to cool the projector and keep it from overheating.
The only parts you should replace are the lamp and air filter. 
If any other part needs replacing, contact your dealer or a 
qualified service person.
¨
Warning: Before you clean any part of the projector, turn off the 
projector and unplug the power cord. Never open any cover on 
the projector, except the lamp and filter covers. 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. Lightly wipe the lens surface with a soft, dry, lint-free 
cloth.
To remove dirt or smears on the lens, moisten a soft cloth 
with an alcohol-based cleaner and gently wipe the lens 
surface.
Cleaning the Projector Case
To clean the projector case, first unplug the power cable. 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.
Do not use alcohol, benzene, thinners or other chemical 
detergents. These can cause the case to warp.

Cleaning the Air Filter
Clean the air filter at the bottom of the projector after every 
100 hours of use. If it is not cleaned periodically, it can 
become clogged with dust, preventing proper ventilation. 
This can cause overheating and damage the projector. To 
clean the air filter, follow these steps:
1. Turn off the projector and unplug the power cable.
2. Turn the projector on its side so that the handle is on top 
and you can access the filter easily.
¨
Note: Standing the projector with the handle at the top keeps 
dust from getting inside the projector housing.
3. Pull up the filter cover tab to release the filter cover. 
Remove the cover.
4. The filter is attached to the inside of the filter cover. It is 
recommended that you use a small vacuum cleaner 
designed for computers and other office equipment to 
clean the filter. If you don’t have one, use a dry, lint-free 
cloth.
If the dirt is difficult to remove or if the filter is torn, 
replace it. Contact your dealer or call EPSON Service 
Center. 
5. Replace the filter cover when you’re done.

Replacing the Lamp   
Replace the lamp when:
• The projected image gets darker or starts to deteriorate.
• The projection lamp indicator is flashing orange.
• The message LAMP REPLACE appears on the screen 
when the projector lamp comes on.
¨
Note: To keep the initial brightness and image quality, replace 
the lamp as soon as possible when the message appears on the 
screen. The replacement message is set to being displayed at about 
1500 hours of use. Contact your local EPSON dealer for a spare 
lamp. Request part number ELPLP09.
¨
Warning: Let the lamp cool before replacing it. Also, do not 
touch the glass portion of the lamp assembly. Touching the glass 
portion of the lamp will result in premature lamp failure.
1. Turn off the projector and unplug the power cable.
2. Turn the projector over so you can access the lamp cover.
3. Use a screwdriver, coin, or similar object to loosen the 
two retaining screws on the lamp cover. When the screws 
are loose, lift off the lamp cover. (You cannot remove 
these screws from the cover.)

Problems with the Projector
If you have problems with the projector, first turn it off and 
unplug it. Then plug the power cord back in and turn on the 
projector. If this does not solve the problem, check the 
warning lights at the top of the projector. These lights alert 
you to problems with projector operation. 
See the following pages for information on what to do when 
you see these warning lights or encounter other specific 
problems with the projector.
qThe operation indicator is flashing orange and you 
cannot turn on the projector.
The lamp is cooling down. Wait until the light turns off and 
then turn on the projector.

Turn off the projector, check that the power cable is 
connected securely both at the power outlet and the 
projector, and press the Power button again.

or the lamp indicator is red.
