Abstract
A color printing machine with a hybrid development architecture is provided including a photoreceptor, a first and second set of development housings, a biased transfer belt, and a fuser. The first set of development housings are arranged in an image-on-image configuration in proximity to the photoreceptor. The biased transfer belt is in proximity to the photoreceptor at a transfer station. The second set of development housings are arranged in a tandem configuration in proximity to the biased transfer belt. The fuser is in proximity to the biased transfer belt.
Claims20
A xerographic printing machine with a hybrid development architecture, comprising:
- a photoreceptor;
- a plurality of first development housings arranged in an image-on-image configuration in proximity to the photoreceptor;
- a biased transfer belt in proximity to the photoreceptor at a transfer station;
- at least two second development housings arranged in a tandem configuration in proximity to the biased transfer belt;
- and
- a fuser in proximity to the biased transfer belt.
A xerographic printing machine, comprising:
- a photoreceptor;
- four first development housings arranged in an image-on-image configuration in proximity to the photoreceptor, each first development housing including a different one of:
- cyan, yellow, magenta and black development material;
- a biased transfer belt in proximity to the photoreceptor at a transfer station, the biased transfer belt being driven to rotate by a plurality of biased transfer rollers;
- at least two second development housings arranged in a tandem configuration in proximity to the biased transfer belt, each second development housing including at least one additional color to provide:
- gamut expansion, spot color, custom color and/or gloss;
- and
- a fuser in proximity to the biased transfer belt,
- wherein the biased transfer belt and the biased transfer rollers provide a mechanical pressure and an electrostatic field to provide transfer of a color image from the photoreceptor onto a substrate and transport of the substrate past the at least two second development housings and to the fuser.
A method of using a xerographic printing machine with a hybrid development architecture, comprising:
- developing an image onto a photoreceptor using a plurality of first development housings arranged in an image-on-image configuration in proximity to the photoreceptor;
- driving a biased transfer belt to rotate in contact with a plurality of biased transfer rollers, the biased transfer belt being in proximity to the photoreceptor at a transfer station to effect transfer of the image from the photoreceptor to a substrate;
- developing another image onto the substrate using at least two additional developer materials in at least two second development housings arranged in a tandem configuration in proximity to the biased transfer belt.
