  • Paper input guide for a transfer zone in a xerographic printing apparatus
    Patent number: 6687479
    Abstract: A printing apparatus includes a guide member for directing sheets toward a transfer zone. The guide member defines a set of ribs which hold the sheets above the main surface of the guide member. Thus, any stray marking material which lands on the guide member is relatively unlikely to contact a sheet moving over the guide member.
    Type: Grant

    Date of Patent: February 3, 2004
    Assignee: Xerox Corporation

  • Xerographic cassette with dual waste toner storage
    Patent number: 5778296
    Abstract: A xerographic cassette for a printing or copying machine includes a photoreceptor drum, a cleaning blade, and a waste toner conveyor for conveying waste toner cleaned off the photoreceptor drum by the cleaning blade into the interior of the photoreceptor drum for storage. The conveyor includes a flexible helical wire which acts as an auger. A curved tube portion of the conveyor passes through an auxiliary waste toner container. Once the auxiliary container is substantially full, waste toner is conveyed into the interior of the photoreceptor drum. The auxiliary container is provided with an aperture which enables it to be emptied, thereby prolonging the useful life of the cassette.

  • Color detection and/or recognition apparatus
    Patent number: 5027195
    Abstract: A color detection and/or recognition apparatus comprises a twin row array (16) of detector elements, each element being arranged to produce an electrical signal on detection of a given color. The two rows (21, 22) each comprise a plurality of groups of detector elements, with the elements in each group of at least one of the arrays being sensitive to a respective different color, with corresponding elements in the two rows being sensitive to different colors, and with the four elements of adjacent corresponding pairs of elements in the two rows being sensitive to at least three different colors. THe electrical signals are processed to provide a determination of the detection of color or the recognition of a color. The two rows of detector elements, typically photosensitive sites in CCD arrays, may be formed closely adjacent one another on the same semiconductor substrate, together with CCD shift registers (23, 24) along the outside edges of the two rows.
