Abstract
Scan line bow correction for raster output scanners, and systems that use raster output scanners. Scan line bow correction is performed in raster output scanners having a post-polygon optical system that includes an f-&thgr; lens system that has at least two multiple scan lenses by controllably tilting a second scan lens along the fast-scan axis. Beneficially, the tiltable scan lens is mounted on a mounting pad that includes a threaded hole. A threaded set screw screws into the threaded hole to provide an adjustable support. In practice the threaded hole-set screw should have a high number of threads per millimeter to provide fine bow correction adjustment.
