ABSTRACT:
A laser scanning unit is provided comprising a housing; a scanning assembly including a scanning device; a first light beam source directing a first light beam toward the scanning device; a second light beam source directing a second light beam toward the scanning device; and first and second post-scan optical assemblies located to receive first and second scanning beams reflected from the scanning device. Each post-scan optical assembly may comprise a first, second and third fold mirror, a first f-theta lens located between the first and the second fold mirrors, and a second f-theta lens located to receive light reflected from the third fold mirror and outputting a compensated scanning beam for generating a scan line on a corresponding photoconductive member.
