Abstract: A heat and pressure fusing apparatus for fixing toner images to substrates such as plain paper, the toner comprising a thermoplastic resin. The apparatus includes two nip forming members which cooperate to form a nip having an asymmetrical pressure profile. Thus, the pressure profile through the nip, from entrance to exit, is such that toner images on a substrate passing through the nip are first subjected to relatively low pressure which continues until the toner begins to flow. Once toner flow commences, the images are subjected to pressure high enough to force the toner into the substrate. The nip is readily variable for accommodating different fusing speeds for different processors.

Abstract: A thermal ink jet printhead has a flow directing one-way valve for reducing back-flow directed forces generated by the droplet ejecting ink vapor bubbles, so that most of the bubble generated forces are used to eject ink droplets from the printhead nozzles. The one-way valve is provided by patterning the etch resistant mask to form a flap located at a predetermined position along the ink channels between the heating elements and reservoirs, which is activated by bubble generated forces directed in the opposite direction from the printhead nozzles.

Abstract: Heat and pressure fusing apparatus for fixing toner images. The fusing apparatus is characterized by the separation of the heat and pressure functions such that the heat and pressure are effected at different locations on a thin flexible belt forming the toner contacting surface. A pressure roll cooperates with a stationary mandrel to form a nip through which the belt and copy substrate pass simultaneously. The belt is heated such that by the time it passes through the nip it's temperature together with the applied pressure is sufficient for fusing the toner images passing therethrough.

Abstract: A driven coupling includes three separate cam lobes projecting therefrom that mate with mating female features in a driver coupling. A central straight or tapered bore accepts a conical alignment pin that projects from the driver coupling. Since the cam lobes are independent and are able to radically deflect, under torque load the central bore is closed down to create a highly precise alignment.

Abstract: A thermal ink jet printer having redundant printing capability includes a primary printhead for printing ink drops of a first color and a secondary printhead for printing ink drops of the first color and/or other colors. The secondary printhead selectively prints according to either a first mode or a second mode. In the first mode, the secondary printhead supplements the primary printhead such that both printheads print ink drops of the first color. In the second mode, if the primary printhead fails, the secondary printhead prints ink drops of the first color in place of the primary printhead.

Abstract: A method of skipping white spaces during the marking of an image onto a recording medium with a marking device includes the steps of detecting a white space in the image between a previous image block and a next image block, positioning a marking element of the marking device adjacent an output starting position on the recording medium, and marking the next image block on the recording medium. The marking device includes a marking element and a controller. Each white space is interposed between two image blocks, which include adjacent image data lines. The controller controls the marking element to mark the image in swaths. Each swath of the marking element is capable of marking more than one image data line. The output starting position is determined such that the marking device marks the next print block using a minimum number of swaths. As a result, the operating speed and throughput of the marking device are increased.
