  • Transport for printing systems
    Patent number: 8282097
    Abstract: A transport system for cut sheet media has a first and second cylinder to form a nip, a support subsystem to transport edges of cut sheets having at least one image into and out of the nip, and an array of contact points on each cylinder to make contact with the cut sheets without marking the image. A wheel for a print medium transport system has an outer rim having a series of contact points, an inner hub supporting a means to accommodate a drive shaft, and an internal spring connecting the outer rim to the inner hub. A method of transporting cut sheets in a printing system forms a nip between at least one pair of cylinders, each cylinder having an array of contact points, guides a first edge of a cut sheet into the nip, and uses the arrays of contact points to transport the cut sheets through one of either a fusing or drying process.
