Abstract
A dual format pre-objective scanner optionally, usable as a laser printer, having an incident beam from input optics incident on a polygon tower which is comprised of a first polygon and a second polygon rotating about an axis common to both the first and second polygon, the polygon tower capable of moving in a vertical direction so that the incident light is directed in a plane approximately perpendicular to the axis rotation of the first and second polygon, at either the first polygon or the second polygon, and with the polygon tower further being capable of moving in a lateral direction approximately perpendicular to the axis of rotation of the polygon tower or moved simultaneously both vertically and laterally so that incident beams on the facets of the first polygon become incident on the facets of the second polygon at approximately the same distance from a scan lens.
