  • Publication number: 20090310988
    Abstract: In a method for electrographic printing of color images on a final image carrier, charge images of the images to be printed are generated on a charge image carrier and are developed into toner images with toner, the toner images being transferred onto an intermediate carrier from which they are transfer-printed onto the final image carrier. The charge images for the individual colors of the color image are generated in succession on the charge image carrier and are developed into individual color toner images with color toner. The individual color toner images are transferred onto the transfer belt and are there collected atop of one another in a color collection cycle to form a complete color toner image. Before the transfer printing of the complete color toner image on the final image carrier, the final image carrier is pivoted onto the transfer belt, and after the transfer printing, the final image carrier is pivoted away from the transfer belt.
