    Abstract: The image forming apparatus can retain a stable and high image quality for many hours without use of any high precise mechanical parts and without causing any non-uniformity and mal-registration in color image. In the image forming apparatus, an image recording medium (photosensitive drum) (6a) is driven by a rotative driving mechanism (pulleys and belts); and an image recording section (print bar) (6c) records an image repeatedly on the rotating image recording medium (6a) in a direction perpendicular to a rotational direction of the image recording medium. The image recorded on the image recording medium (6a) is transcribed onto an image transcribing medium (paper) (22) being fed in the rotational direction of the image recording medium (6a) to form an image. In particular, the apparatus comprises a rotation detecting section (rotary encoder) (6r) for detecting angular travel rates of the image recording medium (6a); and a recording timing control section (5) for controlling recording timing (HSYNC) at which the image is started to be recorded in the direction perpendicular to the rotational direction of the image recording medium (6a), on the basis of the angular travel rates detected by the rotation detecting section (6r).

    Abstract: Precise positioning of image data on an imaging belt (30) in the electrostatographic printing process is accomplished using a positioning means. Lateral position of the imaging belt (30) is detected using a light source (40) and photodetector (44,72,130,208,226) determine an imaging belt edge position and tying the transfer of image data to that position. Circumferential position of the imaging belt is detected using one or more transparent windows which pass over the photodetector (44,72,130,208,226) which, in turn, is illuminated by the light source (40) when a window passes it. The signal from the detector is used to calculate a circumferential adjustment and either the light source or imaging belt motion is adjusted accordingly. Nonoptical embodiments using magnetic or capacitive detectors also can be used to detect the imaging belt circumferential position. A method for positioning image data on an imaging belt is also disclosed.

    Abstract: A method and means for compensating for lateral registration errors in printing machines of the type having a plurality of image processing stations (A,B,C) for forming a composite image on an imageable surface (13) which moves relative to the stations. Monitoring means (146,156) are provided for determining the angular displacement ⌀ of the surface from a reference (302) in the process direction to thereby determine the lateral registration error at each of the image processing stations. Actuating means (138) are provided to move the image processing stations laterally relative to the surface to provide lateral registration of the images formed on the surface. Means may also be provided for compensating for process direction registration errors including means (139) to rotate the image processing stations relative to the surface to provide process direction registration of the images formed on the surface.

    Abstract: An apparatus (100) for assembling components of a color optical scanner subassembly which includes a first filter member (80), a second filter member (70) and a photosensor unit (52). The apparatus includes an imaging means (50, etc.) for impinging an imaging light beam from a line object onto the first and second filter assemblies (80, 70) for producing spatially separated color component images (53, 55, 57) of the line object on the photosensor unit (52). The apparatus (100) also includes a physical adjustment assembly (114, 116, 120, 122, 126, 128, 132, 134, 150, 156, etc.) for holding and selectively adjusting the relative position of the first filter member (80), the second filter member (70) and the photosensor unit (52) in response to data signals generated by the photosensor unit. This positioning accurately locates the filter members relative to the photosensor unit for optimizing performance of the color optical scanner.

    Abstract: A scanning polygon in a ROS system is driven by a motor (20) whose speed is varied in response to desired changes in the resolution of the scan line being formed at a photosensitive surface. The motor of choice is a 2-phase AC hysteresis synchronous motor which is run by square wave input signals (48, 50) to the two motor windings which are 90° out of phase. The motor input signals are at a power level which is variable (36) in response to changes (33) in the frequency of the square wave inputs. The power level variations are applied at the wave front transition so as to prevent the motor from jumping out of synchronism at these points, thus enabling smooth motor operation.
