  • Stripper assembly and a printing machine including the same
    Publication number: 20070116504
    Abstract: A stripper assembly strips a media sheet from a photoreceptor belt. A support bracket supports a stripping finger base which includes a multiplicity of attached stripping fingers. The support bracket is fixed proximate to the photoreceptor belt in a media stripping position. Each stripping finger has a protruding distal stripping end extending toward the photoreceptor belt to form a gap therewith. The magnitude of the stripping finger-photoreceptor belt gap is controlled by adjusting the position or spacing of the finger base with respect to the support bracket. The support bracket pivots about an inboard pivot axial. The opposite support bracket outboard end is releasable, thus enabling the support bracket to pivot away from the photoreceptor belt.

  • Sheet separating apparatus and method of separating sheets
    Publication number: 20070045936
    Abstract: A sheet separating mechanism and a method of separating sheets that includes a retard surface carrier that causes a retard surface to apply an alternately higher and lower friction force against the edge of an underlying sheet. The alternation of the higher and lower friction force can be coupled to a vacuum sheet feeder. The retard surface can be translated to present a next portion of the retard surface to the edge of the next underlying sheet with the translation coupled to the vacuum sheet feeder.
