    Abstract: A document handling system for making multiple precollated copy sheet sets from a set of individual document sheets. The documents are recirculated between a pair of web scrolls and repeatedly imaged on an exposed intermediate web segment extending between the two scrolls. One web scroll is inside wound and above the plane of the intermediate segment, and a second scroll is outside wound and below the plane of the intermediate segment so as to provide unobstructed document loading and unloading access. The documents are retained before and on the second scroll by means of a second web unwound from a third scroll and commonly wound on the second scroll. The third scroll is movable from adjacent the document imaging area to another position in which the two webs separate on the second scroll. The second web does not pass through the document imaging area.

    Abstract: Raster output scanners having piezoelectric-activated lens movers comprised of a mounting base, an electrically operated piezoelectric element connected to the mounting base, a flexible linkage having a lens mount, and a lens attached to the lens mount. The flexible linkage includes flexible arms that can flex in the predominate direction of motion of the piezoelectric element, but that are substantially rigid in another direction. The flexible linkage is mounted such that the flexible arms bias the lens toward the piezoelectric element. Expansion and contraction of the piezoelectric element, combined with the bias of the flexible arms cause the lens mount and its attached lens to follow the expansion and contraction of the piezoelectric element. The rigidity of the flexible arms hold the lens in the proper focal plane. Beneficially, the piezoelectric element is driven so as to compensate for scan line position errors.

    Abstract: A single pass highlight color printer is disclosed which utilizes two pairs of Raster Output Scan (ROS) systems mounted symmetrically about a common polygon motor assembly. Four identical optical systems are thus provided, 180.degree. apart with diode laser outputs directed from a ROS frame parallel and separated to allow the appropriate spacing for xerographic components situated adjacent the xerographic belt. Each ROS unit includes a 90.degree. mirror pair which is mounted on a roof mirror carriage which in turn is connected to a focus carriage via an adjustable guide system. The interaction between the focus carriage and the roof mirror carriage enables a skew alignment and process (beam steering) adjustment to be accomplished with a high degree of precision.

    Abstract: In an overfilled ROS polygon architecture, stray reflection from facets adjacent the completely filled (illuminated) facet are prevented from affecting the scan line images by aligning the optical axis of the pre-polygon and post-polygon optical components at an optimum angle .phi.' so that the stray light reflections at the photoreceptor occur only at non-image forming scan times (outside the image scan time). The optimum angle .phi.' is expressed by the relationship .phi.'=2(.OMEGA..+-.1/2.theta.) where .OMEGA. is given by the expression 360/X, X being the number of scanning facets, and .theta. being the scanning angle.

    Abstract: A raster output scanner assembly having a first laser source for producing first and second laser beams, and a second laser source for producing third a fourth laser beams. The first and second laser beams are directed to a first rotating, multifaceted polygon while the third and fourth laser beams are directed to a second rotating, multifaceted polygon. The first polygon reflects the first and second laser beams onto a moving photoreceptor while the second polygon reflects the third and fourth laser beams onto the photoreceptor. The spots produced by the various laser beams are interlaced such that the scan line produced by the third laser beam is between the scan lines produced by the first and second laser beams, while the scan line produced by the fourth laser beam is adjacent the scan line produced by the second laser beam.

    Abstract: Raster output scanner assemblies, and systems which use such assemblies, having mirrors mounted on the outside of an outer frame. Slits in the outer frame enable light to reflect from the mirrors. Beneficially, the outside mirror or mirrors are protected from contamination by mounting the primary surface of the mirrors (the surface which reflects light) against the outer frame and by mounting a cover over the mirrors.

    Abstract: A document scanning system is disclosed which utilizes a scan carriage mounted on guide rails which are connected between novel support members. The support members are mounted at one location only to a fixed base support. 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. The second embodiment of the invention uses a single guide rail to support the optical system rather than plural guide rails.

    Abstract: An optical system is provided for a copying apparatus which includes a plurality of components whose displacements relative to each other can be made to yield differing magnification at an imaging plane. In particular, during a magnification mode a dual rate scanning mirror pair is displaced a fixed distance and a catadioptric lens is displaced an identical distance, from their normal 1x positions. A third mirror, located at the photoreceptor plane is displaced a second distance. The displacements are a function of the magnification, the lens focal length and the angular displacement of the lens. All displacements are parallel to the document plane, resulting in a compact scanning system.

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