  • Patent number: 8120889
    Abstract: Exemplary embodiments provide charging systems and methods for effectively delivering charges onto a receptor. The charging system can include a low velocity gas stream, an emitter assembly for providing cathode-to-anode field bias to generate charges from the low velocity gas stream, and an emitter-to-receptor (e.g., photoreceptor) electric bias to enhance the charge delivery to the receptor. The disclosed charging systems and methods can be used to achieve an optimal charging performance at a low projected cost for any suitable receptor that needs to be charged. Exemplary receptors can include a photoreceptor (PR) such as a belt PR or a drum PR, a toner layer, a sheet of media on which toner can be deposited, or a transfer belt in an electrophotographic printing machine.

  • Patent number: 8118382
    Abstract: A method uses temperature measurements for a print head and an imaging member to identify a distance between a print head and an imaging member. The method determines whether the print head at the print position is too close to the imaging member to identify the gap distance without damage to the print head. Then, if the print head is not too close, the print head is heated to quantify the heat sink effect of the imaging member on the print head. This effect is related to a heat transfer function that identifies the gap distance between the imaging member and the print head.

  • Publication number: 20120038697
    Abstract: An improved method of measuring relative positions of adjacent printheads in a printhead array has been developed. A pair of ink dashes is made with different colors of ink from adjacent printheads and an offset distance between the dashes is determined from color density measurements of the two dashes. The offset distance may then be used to adjust the stitch alignment of the two printheads.
