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.

Description

The lamp is burned out,

broken, or not installed

correctly, or the lamp cover is

open. Close the cover or

replace or reseat the lamp, if

necessary, as described on

page 22.

Replace the lamp with a new

one as soon as possible. See

page 22 for instructions. If

you continue to use the lamp,

there is a risk it may break.

The projector has overheated

and turned itself off. Let it

cool for about five minutes,

then turn it back on. Make

sure there is plenty of space

around and under the

projector for ventilation. Also

clean the air filter and air

exhaust vents. If it continues

to overheat, you may need to

replace the air filter.

Rapid cooling is in progress.

Make sure the room is not

above 95 °F and there is

plenty of space around and

under the projector for

ventilation. Clean the air filter

and air vents, if necessary.

The projector is in standby or

sleep mode. You can unplug

it or press the P

Power

button to turn it on.

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 vents on the bottom 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.

1. Turn off the projector, allow it to cool down, and unplug the

power cord.

2. Turn the projector upside down.

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).

If dirt is difficult to remove or the filter is torn, replace it.

Contact your dealer or call Epson at (800) 873-7766

to obtain a new set (part number V13H134A08). 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.
