Abstract: An image sensor assembly includes a sensor base and plural image sensors. Each image sensor includes plural sensor pixels. The plural sensor pixels and the plural image sensors are arranged in the same direction. Each image sensor is fixed on the sensor base, and each image sensor corresponds to a next one so that all image sensors can be aligned. There is a predetermined gap between two adjacent image sensors. Therefore, each image sensor is not skew and shifted when the image sensor assembly is mounted on the carriage, and the skew problem between each image sensor and the carriage base can be solved by micro-adjusting the position of the sensor base relative to the carriage base.

Abstract: A heating element adjusts the curvature of a cylindrical wobble correction mirror to compensate and correct the scan line bow for an optical scanner. A current applied through the heating element along one side of the mirror will cause the mirror to bend vertically for a horizontal beam to adjust the scan line bow for a single beam and approximately equalize the scan line bow for multiple beams.

Abstract: An image sensor sub-assembly for a scanner or other image acquisition device includes an image sensor array that detects light imaged by a scanner optical system and an image sensor module that enables calibration of the position of the image sensor array relative to the optical system. In this way, with the optical system being constructed within tolerances, the module enables alignment of the image sensor array to the optical system by its adjustment. Preferably, the sensor module is calibrated to defined standards, making the optical system's calibration independent of the specific module and the module's calibration independent of the specific optical system used in a given scanner. Preferably, the module enables positioning of the sensor array with six degrees of freedom. Further, the electronic circuit board, on which the sensor array is integrated, is separate from the board, on which the analog to digital converters are located. This has the advantage of enabling replacement of the analog to digital converters, a primary source of improper operation in the scanner's electronic components, without requiring the replacement of the optical sensor array, and thus re-alignment.

Abstract: A four-direction adjustable optical module including a carriage and a CCD module is disclosed. The carriage includes a coupling window for coupling with the CCD module. Each of the two sides of the CCD module includes a screw hole and an elastic device. The elastic device slightly protrudes from the surface of the coupling window. While the CCD module and the coupling window are coupled, screws are employed to screw through the CCD module and into the screw holes of the coupling windows. Therefore, the elastic devices deform by the stress from the CCD module. By adjusting the tightness of the screws, the orientation of the CCD module rotating on the Z axis can be calibrated. Thus, the adjustable optical module of the invention can be calibrated at least in four directions.

Abstract: An image forming apparatus includes DMA control units each of which is provided with DMA controllers. Each DMA controller is provided with a plurality of data buffers respectively corresponding to different addresses in a subscanning direction. Each of a predetermined number of pixel data in a main scanning direction is stored in an associated one of the data buffers. Pixel data stored in each of the data buffers are output to an image memory based on the address in the subscanning direction, which corresponds to the associated data buffer.

Abstract: Sub-raster registration errors are compensated for through non-redundant overwriting. Data from adjacent rasters is written to a particular output raster so that the adjacent rasters share an influence at a point actually written to by a rendering device, thereby compensating for a sub-raster component of a registration error associated with writing to the particular point. If two writing passes per raster are used and the writing passes have equal influence (e.g., are written with equal power), then writing data from a first raster during a first pass and writing data from a second raster adjacent to the first raster during a second pass compensates for a sub-raster registration error of half a raster spacing. If two writing passes are associated with different influence (e.g., are written with ⅓ and ⅔ power respectively) and/or if additional writing passes are used, then addition sub-raster positions can be compensated for or emulated.

Abstract: An image forming apparatus has a scanning unit capable of forming a plurality of lines of an image simultaneously by scanning, in a main scanning direction, laser beam that has been emitted from a plurality of laser emitting devices. The apparatus has a memory for storing an error characteristic, in a sub-scanning direction with respect to an ideal scanning line in the main scanning direction, of a scanning line scanned by the scanning unit. A line on which image data is read out is changed over in accordance with a line changeover position in the main scanning direction based upon the error characteristic and a revised pixel position in the main scanning direction in the image data.

Abstract: An optical scanner includes a light source modulated based on image data, an optical deflection and scanning part deflecting a light beam emitted from the light source, and a scanning and imaging optical system condensing the deflected light beam toward a scanning surface so as to form a light spot optically scanning the scanning surface. The effective scanning region of the scanning surface is divided into a plurality of regions according to a scanning line curving characteristic. Suitable image data for optically scanning the divided regions are selected from image data of a plurality of image lines every time the light spot optically scans the effective scanning region, so that the image data of each of the image lines is written with scanning line curving being corrected.
