    Abstract: An apparatus to control color registration and image density and a method of calculating a color registration error. The apparatus includes registration marks formed on a transfer belt such that each of the registration marks includes a scan direction component and a slanting direction component at an angle with respect to both the scan direction and the cross-scan direction. The apparatus further includes image density marks formed on the transfer belt, having predetermined image densities, and a registration and image density sensor provided above the registration marks and the image density marks to radiate beams onto the registration marks and the image density marks. The sensor receives beams reflected from the registration marks and the image density marks to produce detection signals, and obtains registration information and image density information from the detection signals. Accordingly, X-offset, Y-offset, printing width error, and skew can be simultaneously compensated for using a single apparatus.

    Abstract: A lens unit (U15) includes a housing (45), an upper and a lower lens arrays (A1′, A2′), and a first and a second prisms (4A, 4B). Each of the lens arrays includes a plurality of lenses, a light-shielding member (4), and a plurality of positioning projections, all of which are integral with each other. Downwardly traveling light which enters the housing (45) through a first slit (45c) formed at an upper portion of the housing (45) is directed upward by the first prism (4A) to pass through the two lens arrays (A1′, A2′). The light is then directed downward by the second prism (4B) to exit the housing through a second slit (45d) formed at a lower portion of the housing (45).

    Abstract: In a method and apparatus for raster scanning optical output device, such as a laser printer or the like, an array of independently addressable light emitting devices, such as an array of solid state lasers, is used to control spot position on an image plane in the slow scan direction. The array is disposed such that the spots emitted from each element of the array impinge the image plane displaced in the slow scan direction from one another. The total distance between all the spots is less than the distance between fast scan direction scan lines. Only a single element of the array is operated per scan line, thus only a single spot is formed on the image plane per scan line. Control of which of the elements of the array emits a light beam per scan line allows control of the spot position in the slow scan direction for that scan line.

    Abstract: A raster scanning system is disclosed which utilizes a laser light source with a plurality of diodes, at least two of which are offset relative to each other. Either one diode or two offset diodes will be selected to scan one scan line. If two offset diodes are selected, two light beams can be generated to scan two partially overlapping paths to form a scan line. By changing the intensity of the two light beams or by selecting two different offset diodes, the scan line can be moved up or down in the sagittal plane. This concept can be used to correct the wobble of a scan line in which case, either one diode or two offset diodes will be selected to scan one scan line in its correct position. Also, the same concept can be used to correct a bow of a scan line in which case, either one diode or two offset diodes will be selected for each pixel to correct the bow in accordance with a pre-defined correction data for that pixel which is stored in a memory.
