  • Method and apparatus for controlling the modulation of light beams in a rotating polygon type image forming apparatus
    Patent number: 5818507
    Abstract: An apparatus and method for controlling the modulation of an exposing beam of a rotating polygon type image forming apparatus using control marks formed on a rotating surface portion of a polygon member or a motor polygon assembly. The control marks are read by a reader during rotation of the polygon member, and the information read from the control marks is used to control the modulation of the exposing beam of the image forming apparatus to expose evenly spaced, uniformly sized, precisely oriented, geometrically straight scan lines of pixels on a photosensitive member. The control marks can include pixel clock information, intensity correction information, error correction information about individual facets of the polygon member, and motor speed control information.
