Q:
How often should I clean the air filters and vents and how do I clean them?
A:
Clean the air filters and air 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. See Cleaning the Air Filters and Vents.
