Cleaning the Lens

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
Product Information Guide. Refer all other servicing to
qualified service personnel.
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 an alcohol-
based cleaner and gently wipe the lens surface.

Cleaning the Projector Case
Before you clean the projector case, 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 or 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.
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.
