							Maintaining and Transporting the Projector51

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 cause 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 servicer. 
This chapter covers the following:
■Cleaning the lens
■Cleaning the projector case
■Cleaning and replacing the air filter
■Replacing the lamp
■Resetting the lamp timer
■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. 
						

							52Maintaining and Transporting the Projector
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 mild detergent. Then wipe the case. 
■Do not use wax, alcohol, benzene, paint thinner, or other 
chemical detergents. These can damage the case.
caution
Do not use glass cleaner 
to clean the lens. 
						

							Maintaining and Transporting the Projector53
Cleaning and Replacing the Air Filter 
Clean the air filter on 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 upside-down, as shown below.
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 to obtain a 
new one. In Canada, please call (800) 463-7766 to locate a dealer. 
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. 
						

							54Maintaining and Transporting the Projector 4. If you need to replace the filter, lift the tab on the filter cover and 
pull it upward to remove it.
5. Remove the filter.
6. Install the new filter as shown below.
7. Replace the filter cover by inserting the tabs and then pressing 
down the other end until it clicks into place.
