    摘要: Measurements are taken of a first parameter associated with a first marking engine and of a second parameter associated with a second marking engine. The first and second measurements are compared to predetermined first and second reference values. An engine-to-engine difference is determined by calculating a difference between the first measured parameter and the second measured parameter. The difference values are compared to corresponding predetermined threshold values. Based on the comparison, a system controller selects a mode of operation of the document processing system.

    摘要: An imaging system, method and apparatus for producing an image by sensitizing a charge retentive surface of a photoreceptor, image-wise exposing the charge retentive surface to produce an electrostatic latent image, and then transferring the latent image away from the photoreceptor. An intermediate transfer belt carries the latent image to a proximally located development assembly to accommodate deposit of a toner complex onto the latent image to produce a toned image. The toned image is carried to a proximally located toner image transfer assembly that is located a distance from the photoreceptor. The toned image is transferred or transfused to a media carried by a toner image transfer belt located proximally to the intermediate transfer belt.

    摘要: An apparatus in which the developability and interactivity of electrostatically charged particles in a mixture of particulate material is measured. The sensor apparatus includes a transparent member positioned closely adjacent to a developer roller of an electrophotographic printing machine. Electrostatically charged particles are attracted from the particulate mixture being transported by the developer roller to the member. A beam of energy is transmitted through the member. The intensity of the internally reflected beam is detected and a signal generated indicative of the quantity of charged particles adhering to the member. A cleaning field bias is applied, to determine if a signal indicative of the charge particles being removed (interactivity) from the member is generated.

    摘要: Developed image noise is reduced by momentarily breaking the close range forces holding toner non-uniformly to a charge retentive surface in an electrostatic image. The source of the image noise can be of a mechanical nature, such as, raking by carrier beads in conventional two component development. The short range forces are broken by applying ultrasonic vibration to the charge retentive surface.

    摘要: Pyroelectric materials are used to create net charge/surface potentials for use in xerographic charge and transfer steps. Heating and cooling a pyroelectric film, such as, polyvinylidene fluoride induces thermal expansion or contraction which create surface charge density changes that can be used to charge a photoconductive surface and/or transfer an image from a photoconductive surface to a copy sheet.

    摘要: A multi-color printer using a stretch toner release development system to provide either partial or full color copies with minimal degradation of developed toner patterns by subsequent over-development with additional colors and minimal back contamination of developer materials. Multiple scanning beams, each modulated in accordance with distinct color image signals, are scanned across the printer's photoreceptor at relatively widely separated points, there being a buffer provided to control timing of the different color image signals to assure registration of the color images with one another. Each color image is developed prior to scanning of the photoreceptor by the next succeeding beam. After developing of the last color image, the composite color image is transferred to a copy sheet. Development is accomplished by stretching the surface of a toner carrying member and thereby reducing the net force of adhesion of toner to the surface of the toner carrying member.
