  • Patent number: 10274724
    Abstract: A collimation assembly includes a body, at least four light sources, and at least four collimation lenses. The body has inner surfaces that define at least four hollow portions extending through the body between opposed first and second sides thereof, each hollow portion having opposed first and second openings at the first and second sides of the body, respectively. Each light source is disposed at the first opening of one of the at least four hollow portions and controllable to emit a light beam therethrough. Each collimation lens is disposed at the second opening of one of the at least four hollow portions to receive the light beam emitted by the light source disposed at the first opening and diverge the light beam as the light beam passes through the collimation lens. The at least four light sources and the at least four collimation lenses are supported by the body.

  • Patent number: 10095175
    Abstract: A developer roll includes end seal regions subject to accumulating residual toner. An adjacent photoconductive member has a longitudinal extent with a central area defining an imaging region and longitudinal ends outside the central area defining non-imaging regions. The photoconductive member has a length extending beyond a length of the developer roll so that the end seal regions of the developer roll contact the non-imaging regions of the photoconductive member. During cleaning, the non-imaging regions become charged and discharged to electrostatically attract and transfer away the toner from the end seal regions. A blade scrapes clean the toner from the photoconductive member.

  • Patent number: 9423718
    Abstract: A scan unit for an imaging device having a movable mirror and one or more light sources. A light beam generated by each light source is directed towards the movable mirror, movement of the mirror causing each light beam that is reflected by the mirror to follow a distinct scan pattern. An optical assembly is associated with each reflected light beam to form an optical path for each reflected light beam from the mirror. A housing in which the movable mirror, the one or more light sources and the optical assembly are secured has at least a portion made from electrically conductive material for shielding an interior of the housing from electromagnetic fields external to the housing. A light drive circuitry card is disposed in the interior of the housing and communicatively coupled to the one or more light sources for driving the one or more light sources.
