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.

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

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 22).
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.
Follow these steps to replace the lamp and air filters:
1. Turn off the projector.
2. When the P power light stops flashing, unplug the power
cord.
3. Let the projector cool for at least half an hour (if it has been
on). The lamp is extremely hot immediately after use.

at the side and bottom of the projector.
