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 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. 
Do not use alcohol, benzene, thinner, or other chemical detergents. 
These can cause the case to warp. 
						

							Cleaning the Air Filter
137
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 on 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 Accessories at (800) 873-7766 
in the United States and Canada to obtain a new one. 
5. Replace the filter cover when you’re done.
Replacing the Lamp   
The projection lamp typically lasts for about 1500 to 2000 hours of 
use. It is time to replace the lamp when:
❐The projected image gets darker or starts to deteriorate.
❐The projection lamp light is either red, or flashing orange and red 
alternately. 
❐The message LAMP REPLACE appears on the screen when the 
projection lamp comes on (after about 1500 hours of use). To 
maintain projector brightness and image quality, replace the lamp 
as soon as possible.
Contact your dealer or call EPSON Accessories at (800) 873-7766 in 
the United States and Canada for a replacement 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.

							Transporting the Projector
141
Transporting the Projector
The projector contains many glass parts and precision parts. If you 
need to transport it, please follow these packing guidelines to prevent 
damaging the projector: 
❐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 for business use, first put the 
projector in a hard-shell carrying case (such as the optional 
EPSON accessory case), then pack it in a firm box, using 
cushioning around the case. 
❐When you are hand-carrying the projector, be sure to store it in a 
hard-shell or soft carrying case (such as the optional cases offered 
by EPSON).
Note: EPSON shall not be liable for any damages incurred during 
transportation.
