How to Clean a Data Projector

The data projector has undergone a multitude of changes over the years. Early models were large, bulky units which were only able to project an image from a transparent sheet placed on the projector glass. With the advance of technology, data projectors have become more compact and current models can be linked to laptop computers, projecting images and documents stored on the laptop to the screen. These developments have made data projectors indispensable business and teaching tools. Like any tool, however, maintenance is required to keep your equipment running at optimal levels. Fortunately, cleaning your data projector is a simple and straightforward task.

  1. 1

    Clean the lens of your data projector using a soft, dry cloth. Gently wipe the lens in a slow circular motion. Use great care when doing this, as the lens surface is specially treated for light reflection reduction. Avoid touching the lens directly with your hand, as the oils from your skin can damage the lens. Never use a solvent such as benzene, alcohol or a chemical cleaning cloth to remove stains, even if they are stubborn stains. Solvents will permanently damage the surface of the lens.

  2. 2

    Clean the outer cabinet of the data projector with a soft, dry cloth. For stains that cannot be wiped away, use a damp cloth. For stubborn stains, a mild detergent solution may be used. Finish by wiping the surface with a dry cloth. Avoid harsh or abrasive cleaning compounds such as alcohol, benzene and thinners, which can damage the finish on the cabinet. Do not use a previously stained cloth, as this could leave residual scratches in the finish.

  3. 3

    Remove the air filter cover from the bottom of the data projector. On most models, this can be easily accomplished by using the finger grip on the filter. Remove the air filter; it will lift right off. Wash the filter using a mild detergent and lightly dry the filter with dry cloth. Place the filter in a shaded place until it fully dries. Use a portable vacuum to remove dust from inside the projector cabinet. When the filter is fully dried, place it back on the projector and then slide the cover back into place.

  4. 4

    Plug the data projector into a power outlet and turn it on to test that the device is working properly. Your data projector should be working like new.

Tips and warnings

  • Be sure to disconnect the power cord from the AC outlet before cleaning the data projector.
  • Ensure that the air filter cover is tightly secured to the projector or the unit will not turn on.
