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. 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

Cleaning the Air Filter
Clean the air filter at the top 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. Stand the projector with the lens at the top.
♦Note: Standing the projector with the lens at the top keeps dust 
from getting inside the projector housing.
3. Use a small vacuum cleaner designed for computers and 
other office equipment to clean the filter.
If the dirt is difficult to remove or if the filter is torn, 
replace it. Contact your dealer for a spare air filter.

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 
900 hours of use. Contact your local EPSON dealer for a spare 
lamp. Request part number ELPLP14.
♦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 power and allow the unit to cool down, then 
remove the power cord.
The amount of time needed to cool down will depend on 
the ambient temperature.

screwdriver, and pull out the lamp using the handle.
