Maintaining and Transporting the Projector57
Maintaining and 
Transporting the Projector
Your projector needs little maintenance. All you need to do on a 
regular basis is keep the lens clean. Any dirt or smears on the lens may 
show up on your projected image. 
You also need to periodically clean the air filter on 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.
This chapter covers the following:

Cleaning the lens

Cleaning the projector case

Cleaning and replacing the 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 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. 

Use a canister of compressed air to remove dust. 

To remove dirt or smears on the lens, use lens-cleaning paper. If 
necessary, moisten a soft cloth with lens cleaner and gently wipe 
the lens surface. 
Cleaning the Projector Case 
Before you clean the case, first 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. 

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

Cleaning and Replacing 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, allow it to cool down, and unplug the 
power cord.
2. Turn the projector on its side so that the handle is on top and you 
can access the filter easily. 
3. To clean the filter, EPSON recommends using a small vacuum 
cleaner designed for computers and other office equipment. If you 
don’t have one, gently clean the filter using a very soft brush (such 
as an artist’s camel-hair brush).
If the dirt is difficult to remove or if the filter is torn, replace it. 
Contact your dealer or call EPSON at (800) 873-7766 in the 
United States and Canada to obtain a new one. 
note
When you get a 
replacement lamp for your 
projector, a new air filter is 
included. You should 
replace the filter when you 
replace the lamp.

							60Maintaining and Transporting the Projector4. If you need to replace the filter, pull on the catch to remove it. 
Make sure the projector is on its side as shown (not turned upside 
down) to prevent dust from falling inside.
5. To install the new filter, first insert the tabs, then press on the 
catch until it clicks in place.
Replacing the Lamp 
The projection lamp typically lasts for about 1500 hours of use. It is 
time to replace the lamp when:

The projection image gets darker or starts to deteriorate.

The lamp warning light   is flashing red or orange. 

The message LAMP REPLACE appears on the screen when the 
projector lamp comes on (after about 1400 hours of use). To 
maintain projector brightness and image quality, replace the lamp 
as soon as possible.
Contact your dealer or call EPSON at (800) 873-7766 in the United 
States and Canada for a replacement lamp. Request part number 
ELPLP12.

Transporting the Projector
The projector contains many glass and precision parts. If you need to 
transport it, please follow these packing guidelines to prevent damage 
to 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 it in a 
hard-shell carrying case (such as the optional EPSON 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 
carrying case (such as the optional cases offered by EPSON).
note
EPSON shall not be liable 
for any damages incurred 
during transportation.
