  • Patent number: 8396397
    Abstract: In a method and printing apparatus to print a continuous printing substrate, a liquid film with toner and courier fluid is transported to a charge image carrier to develop charge images into toner images. Transport pairs are used comprising rotating transport members in the transport of the liquid film to the charge image carrier and from the charge image carrier to the printing substrate. Given a changing print speed of the printing apparatus at least one of the respective transport pairs is adjusted to provide a respective separation of the transport members from one another so that a substantially same quantity of the liquid film is always conveyed by the respective transport pair.

  • Patent number: 6377768
    Abstract: A device and method for inking a charge pattern of a carrier medium. The device includes a toner sprayer that generates and directs a mixed toner stream onto a surface of an application element. The mixed toner stream includes a number of charge toner and air particles and forms a toner layer when the mixed toner stream contacts the application element surface. The application element is movably positioned in close proximity to the carrier medium for transferring the charged toner particles onto the charge pattern of the carrier medium for inking the same.
