  • Method of cleaning a toner image carrier
    Patent number: 8265539
    Abstract: A method and apparatus for cleaning an image carrier that is used for transferring a toner image onto a recording medium which includes a black image step in which a black image, i.e., an image of the entire area which is filled with toner, is formed on the image carrier and is transferred onto a cleaner that engages the image carrier for removing dust therefrom, wherein, prior to the black image step, a black page step is carried out in which a black page is printed by transferring a black image from the image carrier onto the recording medium.

  • Image-forming element for a printing apparatus with a multiplex circuit for driving the image-forming electrodes
    Patent number: 7548250
    Abstract: An image-forming element for a printing apparatus which includes a support structure with a plurality of electrodes of a first type disposed thereon and an electronic control unit for energizing the electrodes. The image-forming element further includes a plurality of electrodes of a second type, each one of said electrodes of the second type being arranged for interacting capacitively through a dielectric layer with a number of electrodes of the first type, forming a group, the electronic control unit containing a first series of drivers for energizing the electrodes of the first type, each one of said drivers being suited for energizing one electrode of the first type within each group and a second series of drivers for energizing individually the electrodes of the second type, the first and second series of drivers being arranged such that the electrodes of the first type can be individually activated, image wise.
