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.
