<P>PROBLEM TO BE SOLVED: To reduce the size of test patches, reduce the size of inter-documents zones, and adjust the timing/accuracy of a xerographic marking device in real time. <P>SOLUTION: A method of monitoring one or more patches in an image-processing device comprised of a photoreceptor 40, a controller 28, and a sensor 54, includes obtaining specular readings and diffuse readings from the one or more patches and computing values received from the readings. In addition, the one or more patches are from about 0.1 mm to equal or less than the field of view of the sensor 54 where each patch size, location, and approximate value are known; and an analysis of variance (ANOVA) is automatically conducted from the known size, location, and approximate value of each patch. <P>COPYRIGHT: (C)2008,JPO&INPIT |
