Abstract: A printer for forming an inkjet image has an advance mechanism for a print substrate. The printer includes an advance mechanism for moving a print substrate in a transport direction. The advance mechanism includes a feed roller engaging the print substrate on a first surface of the print substrate for applying a driving force thereto and a pressure roller, being arranged opposite to the feed roller. The pressure roller has a textured outer surface which texture is in operation in rolling contact with a second surface of the print substrate. The texture of the outer surface is provided with a plurality of protrusions. The pressure roller diminishes print artifacts, which are related to an irregular crystallization of the hot melt ink.

Abstract: A method of forming a multi-color image, comprising image elements in a first color which along at least part of their circumference adjoin image elements of one or more following colors wherein separation images in the first, second, third and any following color are each built up from image dot patterns of colored toner powder. The separation images are transferred to an intermediate support to collect said separate images to form a multi-color image. The multi-color image is then transferred from the intermediate support to an image receiving material. The second and each following generated separation image is generated so that the image elements, which on transfer onto the intermediate support are required to adjoin image elements of a separation image already transferred thereto previously, at least partially overlap said previously transferred image elements.

Abstract: A printing device for recording information in the form of toner images comprising a moveable image-forming medium on a support, the surface of which forms a dielectric layer; an image-forming station disposed along the trajectory of the image-forming medium having a magnetic roller with an electrically conductive nonmagnetic outer sleeve with magnets disposed inside the sleeve; a means for supplying electrically conductive toner particles to a linear zone in the image-forming station; and a plurality of electrodes for generating an electric field corresponding to a desired image pattern, said electrodes extending in the direction of movement of the image-forming medium and disposed so as to be insulated from one another and covered by a dielectric layer wherein each electrode can be actuated by a voltage source and each electrode can generate an electric field across the dielectric layer over part of the zone wherein image formation takes place when in the image-forming station.
