As your business grows, a reliable projector can be a helpful tool in spreading the word to potential investors or clients about your products and services. Like other projector units, the InFocus DLP projector is susceptible to dust buildup over time. Left untreated, dust buildup can cause murky, cloudy projections, and may even exhaust some of the projector's internal mechanisms. Cleaning your unit is easy, and can prevent costly repair work in the future.

Turn off your projector and disconnect it from its power source. Allow the projector to cool for several hours if it has been used recently.

Locate the latches around the edges of the projector housing and lift them gently. Pry away the housing and set it aside to expose the inside of your projector.

Aim your can of compressed air roughly four inches from the projector and fire short, controlled bursts. Move the can's nozzle all around the projector, firing bursts of air until no more dust exits the device. Clean the projector's housing in the same way.

Replace the housing around the projector unit and close the latches firmly.

Moisten a microfiber cloth lightly and wipe down the outside of the housing. Regular cleaning of the outside can help prevent dust from finding its way inside your projector.

Apply a drop of lens cleaning solution to a lens tissue. Remove the lens cap and wipe the projector lens clean by rotating the tissue in a gentle clockwise motion. Replace the lens cap.

When not using your projector, place it in a cool, dry cabinet or cover it with an antistatic cloth to prevent dust buildup.


Never attempt to use compressed air on the projector when it is in use or if it is still hot following use.
