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 outside 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.
Caution:
Do not use wax, alcohol, benzene, paint thinner, or other
chemicals. These can damage the case.
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.
Caution:
Do not use glass cleaner to clean the lens; this will damage the lens
coating.
Cleaning and Replacing the Air Filter
Your projector includes an air filter to ensure the best
performance. If dust collects on the air filter or vent on the
bottom of the projector, clean them as described below. Dust
clogs prevent proper ventilation and can cause overheating and
damage the projector.
When the filter and vent are clogged, the projector displays the
message
The projector is overheating. Make sure nothing is
blocking the air vent, and clean or replace the air filter
.
To clean the air filter and air intake vent, follow these steps:
1. Turn off the projector, allow it to cool down, and unplug
the power cord.
2. To clean the filter and vent, Epson recommends using a
small vacuum cleaner designed for computers and other
office equipment. If you don’t have one, gently clean them
using a very soft brush (such as an artist’s paintbrush).
You can remove the air filter to clean both sides.
If the dirt is difficult to remove or if the filter is torn, replace
it. Contact your dealer or call Epson at (800) 463-7766 to
obtain a new one (part number V13H134A13).
