Abstract: An improved raster scanner, and electrostatographic printing machines which use such scanners, in which facet tracking is achieved by incorporating a semiconductor laser having an electronically tunable wavelength and a wavelength dispersive element which directs the laser beam onto the facets of a rotating polygon. The wavelength dispersive element is positioned, and the wavelength output from the laser is adjusted, such that as the polygon rotates the laser beam produces a spot on a facet which tracks the facet.

Abstract: A multi-beam scanning device in which generation of differences in scanning speed and curved image planes among a plurality of beams is prevented and pitch adjustment for the plurality of beams in the sub-scanning direction can easily be performed. Cylindrical lenses are provided on respective optical paths extending from a plurality of light sources to a beam splitter, and positions of the cylindrical lenses are adjusted by optical path correcting mechanisms for adjustment of position of the respective beams in the sub-scanning direction. A sensor section receives the respective beams to output to a control circuit a detection signal corresponding to a light receiving position. The control circuit drives an optical path correcting drive circuit based on a predetermined threshold and the output signal to control actions of the optical path correcting mechanisms.

Abstract: Disclosed herein is a method and apparatus for compensating for temperature-induced scan line drift in a photoelectric imaging apparatus. A scan line drift compensation mechanism may be placed in contact with at least one of the optical components, e.g, a mirror, contained within the optical system of a photoelectric imaging apparatus. The scan line drift compensation mechanism may be formed from two members, each having a different coefficient of thermal expansion. In this manner, the scan line drift compensation mechanism is able to exert a force on the optical component in response to a change in temperature.

Abstract: In an optical scanner, a light beam from a light source device is formed by a linear image forming optical system as a linear image extending in a main scan-corresponding direction. The light beam is then deflected by an optical deflector at an equal angular velocity and is converged by an image forming reflecting mirror as a light spot on a scanned face. An optical scanning operation is performed at an equal speed by using this light spot. An error in an image forming position in a cross scan-corresponding direction caused by an error in arrangement of an optical system is corrected by displacing and adjusting an arranging position of the linear image forming optical system in the cross scan-corresponding direction. In the optical scanner using the image forming reflecting mirror, a curve ill a scanning line caused by the error in arrangement of the optical system can be effectively corrected and reduced.

Abstract: A system, including a specially-designed optical element, facilitates extremely precise and accurate registration of a light beam on a photoreceptor. The optical element includes a redirecting cylinder lens, having a longitudinal axis oriented obliquely relative to the scan path of the light beam to redirect the light beam. The redirected light beam interacts with an aperture in the photoreceptor to provide an accurate measuring device for the exact position of the aperture with each scan.

Abstract: A scanning system device has a predetermined aberration as it scans or switches light along selected optical paths. A deformable membrane receives the light and introduces an inverse “aberration” that offsets that of the scanning system. In one embodiment the scanning system includes a torsion arm that supports an oscillatory body. The torsion arm and/or body can be machined from metal, micromachined in silicon or formed in a variety of other ways. Alternatively, the scanning system may include a rotating polygonal scanner or other type of optical scanner. In another approach, an optical switch replaces the scanner.
