  • Method for measuring a gap between an intermediate imaging member and a print head using thermal characteristics
    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.
