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

vacuum cleaner or soft brush to clean the two filters. Slide
the filters back into place when you're done.

Replacing the Lamp and Air Filters

time to replace the lamp when:
The projected image gets darker or starts to deteriorate.

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

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.
