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

Clean the air filter and air intake and exhaust vent on the
bottom of the projector after every 100 hours of use. If they are
not cleaned periodically, they can become clogged with dust,
preventing proper ventilation. This 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 vent, follow these steps:
1. Turn off the projector, allow it to cool down, and unplug
the power cord.
2. Turn the projector upside-down and clean the filter and air
intake vent on the base of the projector.
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 brush).
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).
