Note: You can use the projector’s Effect menu to modify the
highlighting effects for each of the numbered buttons.
Cleaning the Projector and Replacing
Parts
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.
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 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 wax, 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 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.
4. If you need to replace the filter, make sure the projector is on
its side as shown (not turned upside down) to prevent dust
from falling inside. Then press the arrow tab to remove the
filter.
5. To install the new filter, first insert the tabs, then press on
the latch until it clicks in place.
