Cleaning the Air Filter and Vents
Clean the projector's air filter or vents if they get dusty, or if you see a message telling you to clean them.
Turn off the projector and unplug the power cord.
Gently remove the dust using a small vacuum designed for computers or a very soft brush (such as a paintbrush).
If dust is difficult to remove or the air filter is damaged, replace the air filter.
