The projector is overheating, which turns

the lamp off automatically. Wait until the

cooling fan stops, then unplug the power

cord. Plug the cord back in and press the

Power button. Make sure the room

temperature is not above 95 °F (35 °C),

and there is plenty of space around and

under the projector for ventilation.

If you're using the projector above an

altitude of 5,000 feet (1,500 meters),

turn on High Altitude Mode in the

Operation menu. Do not use the projector

above 7,500 feet (2,286 meters).

The air filter or vents may be clogged.

Clean them or replace the air filter.

If the projector continues to overheat after

you clean the air filter, the problem may be

caused by damage to the cooling fan or

temperature sensor. Contact Epson for

help.

Flashing

There is a problem with the fan or

red

temperature sensor. The air filter or vents

may be clogged. Clean them or replace the

air filter.

If this does not resolve the problem, stop

using the projector, disconnect the power

cable, and contact Epson for help.

for instructions. If you continue to use the

lamp after the replacement warning, there

is an increased possibility that the lamp

may break.

Flashing

The lamp may be burnt out. First make

red

sure the lamp cover is securely installed. If

that's not the problem, let the lamp cool,

then replace it as described on page 12.

The air filter or vents may be clogged.

Clean them or replace the air filter. If this

does not resolve the problem, contact

Epson.

Flashing

Power is cut off because of an internal

red

problem. Unplug the power cord and

contact Epson for help.

Maintaining the Projector

Warning: Before you clean any part of the projector, turn it off and

unplug the cord. Never open any cover on the projector, except the

lamp cover. Dangerous electrical voltages in the projector can injure

you severely. Do not try to service this product yourself, except as

specifically explained here or in the User's 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 a commercially

available cloth for cleaning glasses.

Caution: Do not spray liquid or glass cleaner directly on the lens.

Cleaning the Projector Case

Before you clean the 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, wipe the case with a soft

cloth moistened with water and a mild detergent.

Caution: Do not use wax, alcohol, benzene, paint thinner, or other

chemical detergents. These can damage the case.

Cleaning the Air Filter and Vent

Your projector includes an air filter to ensure the best

performance and protect your investment. If dust collects on

the air filter (on the bottom of the projector) or vent (on the

front of the projector), clean them as described below. Dust

clogs prevent proper ventilation and can cause overheating,

which can damage the projector.

Follow these steps:

1. Turn off the projector and unplug the power cord.

2. To clean the intake vent and filter, use a small vacuum

cleaner designed for computers and other office equipment.

If you don't have one, gently clean the vent with a soft

brush (such as an artist's paintbrush).
