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.

Cleaning the Projector

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, moisten a soft cloth with

water and a mild detergent. Then wipe the case.

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

chemical detergents. These can damage the case.

Cleaning the Air Filters and Vents

Clean the air filters and air intake vents 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.

Follow these steps:

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

2. To clean the intake vents, EPSON recommends using a

small vacuum cleaner designed for computers and other

office equipment. If you don't have one, gently clean the

vents with a soft brush (such as an artist's paintbrush).

3. Gently turn the projector over and remove the filters from

the side and bottom of the projector. Then use a small

vacuum cleaner or soft brush to clean the two filters. Slide

the filters back into place when you're done.

4. If the dirt is difficult to remove or a filter is broken, replace

the filters as described below. Contact your dealer or call

EPSON at (800) 873-7766 in the United States to obtain

new ones. In Canada, please call (800) 463-7766 for dealer

referral.

Replacing the Lamp and Air Filters

The life span of the projection lamp is about 2000 hours. It is

time to replace the lamp when:

The projected image gets darker or starts to deteriorate.

The message

LAMP REPLACE

the lamp comes on (after about 1900 hours) and the

lamp warning light is flashing orange. To maintain

projector brightness and image quality, replace the lamp as

soon as possible.

The

lamp warning light is flashing red (the lamp is

burnt out).

Contact your dealer or call EPSON at (800) 873-7766 in the

United States for a replacement lamp. Request part number

V13H010L22. In Canada, please call (800) 463-7766 for

dealer referral.

Note: When you get a replacement lamp for your projector, new

air filters are included. You should replace the filters when you

replace the lamp. You can check how long the lamp has been in

use (see page 20).

Warning: Let the lamp cool fully before replacing it. In the

unlikely event that the lamp has broken, small glass fragments

may be present and should be removed carefully to avoid injury.
