Maintaining and Transporting the Projector61

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 top 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 servicer.
This chapter covers the following:

Cleaning the lens

Cleaning the projector case

Cleaning and replacing the air filter

Replacing the lamp

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.

							62Maintaining and Transporting the Projector
Cleaning the Lens
Clean the lenses 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 lenses, 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 wax, alcohol, benzene, thinner, or other chemical 
detergents. These can damage the case.
Remove the cap 
before cleaning

							Maintaining and Transporting the Projector63
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. Stand the projector on end with the handle on top to keep dust 
and dirt from falling inside.
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 broken, replace it. 
Contact your dealer or call EPSON at (800) 873-7766 in the 
United States to obtain a new one. In Canada, please call 
(800) 463-7766 for dealer referral.
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.

							64Maintaining and Transporting the Projector4. If you need to replace the filter, press the arrow tab and lift up the 
filter to remove it.
5. To install a new filter, first insert the tabs, then press down 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 red or flashing red.

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 
V13H010L15. In 
Canada, please call (800) 463-7766 for dealer referral
Press the arrow tab
warning
Be extremely careful when 
removing the lamp module. 
In the unlikely event that the 
bulb has ruptured, small glas
s 
fragments may be present an
d 
should be removed with 
caution.
If your projector is mounted 
on the ceiling, you should 
unmount it before accessing 
the lamp compartment. This 
will make it easier for you to 
replace the lamp and 
minimize the chance of any 
small glass fragments 
dropping from the projector.
