Removing and cleaning projector optics
For improving brightness and contrast, the procedures are organized from most to least effective.
Cleaning procedures should be performed in a clean, well lit, and dust-free environment that meets or
exceeds Underwriters Laboratories (UL) standard 609.50 and ISO Class 9 Standard for Office
Environments.
For procedures on removing optical components, see the projector service manual. If the
