    摘要: Various systems, methods, and programs embodied in computer readable media are provided for calibration of at least one half-tone density in a printer. In one approach, a method is provided comprising the steps of acquiring a plurality of half-tone density values from a respective plurality of test patches generated on a belt in the printer over a period of time, each of the test patches embodying an intended half-tone density, generating a mathematically smoothed half-tone density value from the half-tone density values, and calibrating a half-tone density in the printer based upon the mathematically smoothed half-tone density value.

    摘要: Xerographic printers may be provided with a photoreceptor belt manufactured so that transparent permanent optical registration marks are formed in defined selected minor areas of the belt without physically weakening the belt, as is the case with belt holes. These permanent registration marks are sufficiently transparent for a conventional belt holes sensor to optically detect them by illumination through those transparent areas of the photoreceptor. The photoreceptor is preferably a plural layer organic photoreceptor with an internal optically opaque metallic ground plane layer, and the optical registration marks are formed by oxidizing defined areas thereof. This may be accomplished by the simultaneous selective application of illumination to these selected minor areas of the photoreceptor, while adjacent areas of the photoreceptor are not illuminated, plus the application of electrical current from a voltage source applied through the belt in those areas.

    摘要: A copier/printer having a transfer station for transferring images from an imaging member to copy sheets includes the improvement of removing debris from the surfaces of copy sheets facing the imaging member before the copy sheets reach the transfer station. At least a pair of cooperating rolls are positioned to form a nip for driving the copy sheets therebetween toward the transfer station. The cooperating rolls include a drive roll and a dielectric roll with the dielectric roll being electrostatically charged by the drive roll and paper through contact and separation during the intercopy gaps between copy sheets in transit to the transfer station through contact with the copy sheets to electrostatically attract debris from the copy sheets.
