Projection Introduction General maintenance Devices The most common types of still picture projectors are the opaque, the overhead, and the 35mm slide projector. You need a working knowledge of the operation and the basic maintenance of the common types of projectors. For general maintenance purposes, inspect the projection device well before presentation day to allow time for the repair of any discrepancies. Likewise, pay attention to the following details: Check the cleanliness of the lenses and projection stages: clean optical surfaces with a lint-free cloth, a damp chamois, or a lens tissue; clean exterior surfaces with a clean, damp cloth; and clean mirrored or reflective condensers with a camel hair brush. Check the device for worn or frayed electrical cords. Test device operation by running the projector for 5 minutes before actual use to make sure it is working properly. Check the projector to screen distance. Keep a spare bulb available next to the projector. Continued on next page 5-3
