    Abstract: A scanner, through which a document moves while being scanned by a moving beam of light, includes a wheel that rotates responsive to document movement. The wheel includes a multi-sectioned optical encoder upon which the scanning beam of light impinges when in a position at which it does not impinge upon the document. The scanner also includes an optical detector which receives light that is not absorbed by the optical encoder sections. Thus, the optical detector generates an electrical signal that indicates document movement speed. A preferred embodiment the scanner includes a pair of cup-shaped wheels one of which carries the optical encoder that encircles an inner surface of the wheel adjacent to a lip thereof. An axle, also included in the preferred embodiment, spans between, is coupled to, and supports the wheels for rotation in unison about a longitudinal axis parallel to the axle.

    Abstract: Color imaging methods and systems allow each color image to be registered in a composite manner. An image-on-image registration controller of an image forming device adjusts the control signals which control the output of image data to reduce or eliminate image registration offsets. In particular, two separate feedback loops are combined to monitor and adjust image registration without going off-line for a set-up procedure. These two feedback loops include a dynamic skew control feedback loop, which monitors and adjusts the edge position of the photoreceptor belt to infer lateral registration, and a direct image registration feedback loop, which monitors and adjusts relative image registration directly. The control signals are adjusted based on a determined image registration offset. The image processing device outputs an image based on the control signals adjusted based on a determined image registration offset. As the image's registration changes, the image-on-image registration controller determines and applies the necessary adjustments to the controls signals to keep the differently-colored images registered throughout the print run. The systems and methods permit many off-line set-up procedures the eliminated and increase the image quality by constantly adjusting for registration offsets.

    Abstract: There is proposed a method and apparatus for multibeam scanning an inner face of a cylindrical drum, in which scanning lines are straightened under a simple control, and an interval between the scanning lines can be easily changed, thereby simplifying a constitution. In an embodiment, while keeping an interval between two light beams projected to an optical scanning system, the light beams are one-dimensionally deflected in mutually orthogonal directions in synchronism with a rotation of the spinner, respectively. In a second embodiment, one light beam is projected along a central axis common with the spinner and the cylindrical drum to the spinner. The other light beams are inclined in a plane including the central axis by a constant angle nully separately predetermined for each of the other light beams, and further inclined in a direction orthogonal to the plane including a rotation axis by an angle nullx which is determined in synchronism with a rotation angle null of the spinner.

    Abstract: An image forming apparatus containing a divisional scanning type optical scanner. In the apparatus, if displacement of one line in a subscanning direction occurs in a joint of image formation areas, light sources are controlled so as to modulate and emit light beams based on image data of the scanning line shifted one line at the same point of time. If displacement of 0.5 pixels in a main scanning direction occurs in a joint of image formation areas, the emission start timing of one light beam is shifted by the scanning time as long as 0.5 pixels with respect to the emission start timing of the other light beam, thereby correcting the displacement amount in the main scanning direction.

    Abstract: An image forming apparatus and method wherein a writing device writes information of an image on a photoconductive body traveling in the sub-scanning direction to form an electrostatic latent image of the image thereupon by driving a light source to emit luminous flux, in response to an image signal corresponding to the image information, using a write clock and scanning the luminous flux from the light source with a scanning device in the main scanning direction on the photoconductive drum. The electrostatic latent image on the photoconductive body is developed by a developing device to a toner image, a transfer sheet having a size in the main scanning direction is selected by a selecting device, and the toner image on the photoconductive body is transferred by a transfer device to the selected transfer paper. The write clock is reset on the basis of information of the size of the selected transfer paper in the main scanning direction such that a magnification error of the writing device in the main scanning direction of the image is corrected.
