  • Patent number: 7746509
    Abstract: A method for removing show-through defects in scanned document images is provided by adjusting the scanner's image sensor calibration gain in the area of a drive roll gap. The method will also compensate for drive roll contamination. The invention uses a modified calibration scheme in conjunction with a document transmission sensor in the document handler to measure radiant energy transmitted through the document, i.e., transmission. The scanner adjusts the calibration gain factors to simulate a uniform background with knowledge of the gap and the input document's transmission thus a uniform scanner response is determined and presented to the image processing. A device for carrying out the method is also provided.

  • Patent number: 7747184
    Abstract: The dielectric thickness of a photoreceptor is determined in a variety of ways, including using a relationship between threshold voltage and dielectric thickness, using a relationship between dielectric thickness and the difference between biased transfer roller (BTR) voltage and photoreceptor surface potential, using a relationship between dielectric thickness and biased charging roller (BCR) impedance, using a relationship between dielectric thickness and the slope of the DC current vs. voltage curve for the BTR or the BCR, and using a relationship between dielectric thickness and the BTR voltage at zero current. The threshold voltage can be found by using the slope of the BCR DC current vs. voltage curve, measuring photoreceptor surface potential for a plurality of target values below the charging knee to obtain the intercept value, or finding the actual value of the charging knee. A method of using the BCR as an electrodynamic voltmeter is also disclosed.
