  • Patent number: 7675259
    Abstract: A first determining section determines whether a recording medium is conveyed in a first direction. A setting section sets a first current value as a current initially outputted to a DC motor each time the first determining section determines that the recording medium is conveyed in the first direction. A first current outputting section outputs a current at the first current value, and subsequently outputs by steps a current gradually higher than the first current value motor until the first determining section again determines that the recording medium is conveyed in the first direction. A second determining section determines whether the recording medium is conveyed in a second direction opposite the first direction after the first current outputting section outputs a current at the first current value.

    Abstract: Provided are an image drum and a method of manufacturing the image drum. The image drum includes multiple ring electrodes arranged along a longitudinal direction of a drum body and on an outer circumferential surface of the drum body. The ring electrodes are separated from each other. Between the ring electrodes there are ring insulator molds. The image drum can be manufactured by patterning a seed layer on the outer surface of the drum body, forming multiple ring insulator molds on the seed layer, and depositing a conductive material between the ring insulator molds to form the ring electrodes.

  • Patent number: 7643678
    Abstract: Xerographic machines can print documents that have unintentional streaking parallel to the process direction. There are many possible source of the streaking. Currently, the streaking is minimized by using a cross process direction dependent modulation, called a profile, to modulate a modulated light beam being scanned across the photoreceptor. The profile is purely a function of cross process direction position. The profile can minimize, and often eliminate, streaking for any one area coverage, but only for that one area coverage. Different profiles can be produced that work best for different area coverages. Choosing a profile from a group of profiles for use with each scan line can minimize parallel streaking for a wider range of area coverages.

  • Publication number: 20090225146
    Abstract: A multi-beam scanning device for focusing deflected light beams onto an object to be scanned includes a light source unit, a deflector, a pitch adjustment device, and a conical-shape compression-torsion coil spring. The light source unit is rotatable about an optical axis and includes a plurality of light sources to emit the light beams and a plurality of coupling lenses disposed corresponding to the light sources. The deflector deflects the light beams emitted from the plurality of the light sources and passed through the plurality of the coupling lenses. The pitch adjustment device moves the light source unit in a first direction around the optical axis to adjust a beam pitch. The conical-shape compression-torsion coil spring urges the light source unit in a second direction opposite the first direction around the optical axis as well as in the optical axis direction. An image forming apparatus includes the multi-beam scanning device.

  • Patent number: 7469191
    Abstract: The present invention measures jitter in a galvano scanner that scans a light beam on a surface to be scanned by periodically turning a reflection mirror in a reciprocating manner. Two detectors for detecting and receiving the light beam are mounted near both ends of the scan region of the light beam, a first detection signal of each of the two detectors is extracted whenever the reflection mirror is activated for one scanning, a required time for one scanning is computed from the extracted detection signals, and a variation in the required time for each scanning is measured based on the computed required time.
