摘要： A raster output scanner assembly (36) having a first laser source (104) for producing first and second laser beams (A & B), and a second laser source (204) for producing third and fourth laser beams (C & D). The first and second laser beams (A & B) are directed to a first rotating, multifaceted polygon (110) while the third and fourth laser beams (C & D) are directed to a second rotating, multifaceted polygon (210). The first polygon (110) reflects the first and second laser beams (A & B) onto a moving photoreceptor (20) while the second polygon (210) reflects the third and fourth laser beams (C & D) onto the photoreceptor (20). The spots produced by the various laser beams are interlaced such that the scan line produced by the third laser beam (C) is between the scan lines produced by the first and second laser beams (A & B), while the scan line produced by the fourth laser beam (D) is adjacent the scan line produced by the second laser beam (B).

摘要： In an optical scanning apparatus having an overfilled ROS polygon (24), stray reflection from facets (24R) adjacent the completely filled (illuminated) facet (24A) are prevented from affecting the scan line images by aligning the optical axes (40,50) of the pre-polygon and post-polygon optical components at an optimum angle Φ' so that the stray light reflections at the photoreceptor (32) occur only at non-image forming scan times (outside the image scan time). The optimum angle Φ' is expressed by the relationship Φ' = 2(Ω ± ½ ϑ) where Ω is given by the expression 360/X, X being the number of scanning facets, and ϑ being the scanning angle.

摘要： Electrophotographic printers have raster output scanners (27) that correct for polygon facet (126) phasing errors and photoreceptor (10) position errors by aerial scan line adjustments. A photoreceptor position sensor senses the position of the photoreceptor (10) and a facet position sensor (137) senses the position of the polygon facets. A scan line position controller (119) produces a position signal that depends upon the photoreceptor position sensor and the facet position sensor (137). A piezoelectric-actuated lens mover assembly (118) receives the position signal and moves a pre-polygon lens (116) to adjust the scan line plane to correct for any misregistration. The piezoelectric-actuated lens mover assembly (118) includes a large displacement piezoelectric element and a flexible arm assembly (210) that holds the pre-polygon lens (116).

摘要： A document scanning system is disclosed which utilizes a scan carriage (8) mounted on guide rails (10) which are connected between support members (36, 42). The support members are mounted at one location only to a fixed base support (44). The guide rails do not require mounting to a side frame structure; the support structure providing the stability usually provided by the sides of a frame. The guide rails are inherently stable and provide the support for the scan load components. In a second embodiment, the scan carriage is mounted on a single guide rail.
