Yesterday I received an email titled, “Burning Smell??” Yikes!
Luckily it turned out to just be a dust-clogged projector. Molten plastic was not dripping down onto the floor. This particular classroom uses the projector all day. They have technology integrated into nearly everything. It is bound to get plugged up with dust sooner or later.
Most projectors have a filter located near the front of the projector next to the lens. All you need to do is slide it out, blow the dust out and slide it back in. Be sure that it is slide all of the way back in, otherwise it can cause future problems.
Here is the manual for the projectors that the Activ3 Promethean boards use. This model, the XE40 by Sanyo) actually has two filters. The directions for cleaning the filters begin on page 54 of the manual.
The filters should probably be cleaned bi-monthly… if not monthly to avoid overheating the projector.
