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 side 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 side 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. To prevent dust from falling into the projector, place the 
projector 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. 
4. If you need to replace the filter, lift the tab and pull it upward to 
remove the filter.
5. To install the new filter, first insert the tabs, then press down on 
the opposite end of the filter until it clicks in place.
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.

Replacing the Lamp 
The projection lamp typically lasts for about 1500 hours of use. It is 
time to replace the lamp when:
■The projected image gets darker or starts to deteriorate.
■The   warning light is red, flashing red, or flashing orange. 
■The message LAMP REPLACE appears on the screen when the 
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 for a replacement lamp. Request part number 
V13H010L18. In 
Canada, please call (800) 463-7766 to locate a dealer. 
Follow these steps to replace the lamp:
1. Turn off the projector, wait for the cool down period to end, then 
unplug the power cord.
2. Allow the projector to cool down for at least half an hour (if it has 
been on).
3. Turn the projector upside-down to access the lamp compartment.
4. Press the two tabs and remove the lamp cover.

note
You can check to see how 
many hours the lamp has 
been used. See page 48.
warning
Let the lamp cool before 
replacing it. If the lamp 
breaks, handle the shards 
carefully to avoid injury.
