Epson ELP-3000 - Manual (Page 68)

Maintenance
T
he projector needs little maintenance. You should keep the lens clean because
any dirt or stains will appear on the screen. You also need to periodically clean
the air filter, which is located at the bottom of the projector. Keeping the air filter
clean is important because a clogged air filter prevents proper ventilation, which
is necessary to cool the projector
and prevent it from overheating.
You should also clean the trackball on the remote control whenever you notice
that the trackball is not rotating smoothly due to dirt and dust that have collected
on the trackball.
The only parts you should replace are the lamp, air filter, and fuse. If any other
part needs replacing, contact your ELP-3000 dealer or a qualified service person,
Whenever you clean any part of the projector, always turn off the projector and
unplug it first.
