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.
Caution:
Do not use glass cleaner to clean the lens.
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, wipe the case with a soft
cloth moistened with a mild detergent.
Caution:
Do not use wax, alcohol, benzene, paint thinner, or other
chemical detergents. These can damage the case.
Cleaning and Replacing the Air Filter
Clean the air filter and air intake and exhaust vents on the
bottom and rear of the projector after every 100 hours of use.
If not cleaned periodically, they can become clogged with dust,
preventing proper ventilation. This can cause overheating and
damage the projector. When the filter is clogged, the projector
displays the message
The projector is overheated.
To clean the air filter and air vents, follow these steps:
1. Turn off the projector, allow it to cool down, and unplug the
power cord.
2. Clean the air vent on the back of the projector.
Use a small vacuum cleaner designed for computers and
other office equipment. If you don’t have one, use a very soft
brush (such as an artist’s brush).
3. Turn the projector upside-down and clean the filter and air
intake vents on the base of the projector.
If dirt is difficult to remove or the filter is torn, replace it.
The air filter set (part number V13H134A06) contains two
filters. Contact your dealer or call Epson at (800) 873-7766
to obtain a new set. 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. Replace the filter when you replace the lamp.
