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 Users Guide. Refer all other servicing to qualified service 
personnel.

Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the 
surface. Wipe the lens surface gently with a soft, dry, lint-free 
cloth. To remove dirt or stains on the lens, moisten a soft 
cloth with water and a neutral detergent 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 casing 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 casing.
Do not use alcohol, benzene, thinners or other chemical 
detergents. These can cause the casing 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 dont 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 youre done.

Replacing the Lamp
The projector lamp typically lasts for about 2000 hours of use. 
It is time to 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.
Contact your local EPSON dealer for a replacement lamp.Use 
only replacement lamp part number.(ELPLP06 or ELPLP07)
¨
Caution: This projector lamp develops high heat and high 
pressure during use, so the lamp (bulb) ruptures and burns may 
occur. To avoid serious injury, before attempting to replace the 
lamp, pull out the power cord plug from the outlet and wait for 
the lamp (bulb) to cool (wait at least one hour). 
1. Turn off the projector and unplug the power cable.
2. Place the projector on its side with the handle at the top 
so you can easily access the lamp cover.
¨
Note: Placing the projector in this position keeps dust from 
getting inside the projector housing.
