Abstract: A registration apparatus for positioning a medium on a media support surface, includes a moveable member and a registration member. The moveable member is contacted by an edge of a medium, and moves therewith as the medium is moved to a set position on a support surface. The registration member restrains the movement of the moveable member, at the point at which the moveable member contacts the registration member, to position the medium at the set position on the support surface.

Abstract: A multibeam scanning system for scanning an imaging surface, includes at least one radiation emitter configured to emit a first beam of radiation and a second beam of radiation. A spin deflector, rotatable about a spin axis, is provided to direct the first beam to form a first scan line and the second beam to form a second scan line on the imaging surface. At least one moving element, such as a translating lens, disposed upstream of said spin deflector, operates to deflect at least one of the beams with respect to the spin axis of the spin deflector.
