Warning:
Except as specifically explained in the User’s Guide, do not attempt
to service this product yourself.
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 and do not spray liquid of
any kind directly on the lens. Spray the cleaner on a soft cloth and
then gently wipe the lens with the cloth.
Cleaning the Projector Case
Turn off the projector and unplug the power cord before you
clean the case.
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. Do not spray cleaner directly
on the projector.
Cleaning and Replacing the Air Filter
Clean the air filter and air intake 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.
Follow these steps:
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 paintbrush).
If dirt is difficult to remove or the filter is torn, replace it.
The air filter set (part number
V13H134A08) contains two
filters. See page 13 for ordering information.
Red The projector is overheating, which turns
the lamp off automatically. Wait until the
cooling fan stops, then unplug the power
cord. Plug the power cord back in and
press the P 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.
The air filters may be clogged. Clean or
replace them as described in the next
column. 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.
