    摘要： A method of calibrating a printing system for positioning at least one printed image, the printing system includes a first image bearing surface, the method includes: a) forming a background pattern and at least three fiducials on the first image bearing surface, wherein the background pattern is larger than a first printed image and the at least three fiducials are within an area formed by the first printed image; b) transferring a portion of the first printed image to a second image bearing surface; c) measuring a first residual image on the first image bearing surface, wherein the first residual image is a portion of the background pattern and the at least three fiducials remaining on the first image bearing surface after the step of transferring; and, d) calculating at least one calibration parameter for the printing system based on the measuring of the first residual image.

    摘要： A magnification adjustment method for a document processing system having a fixed frequency clock source providing a fixed frequency output signal to a plurality of raster output scanners (ROSs) and a numerically controlled oscillator (NCO)-based adjustable frequency clock source providing an adjustable frequency output signal to the ROSs is disclosed. The method includes: using a controller to determine a frequency setting for a phase increment control input signal to the adjustable frequency clock source; starting the document processing system; using the controller to set a phase accumulator control input to the frequency setting; sending a message to a ROS control module prior to imaging, including the correct clock source to use for the next image, the correct clock source being either the fixed frequency clock source or the adjustable frequency clock source; and applying the correct clock source synchronously to the beginning of an inter image panel zone.

    摘要： Document processing systems and duplex printing methods are presented in which side 1 to side 2 process magnification errors are compensated for by selective use of two raster output scanner clocks for latent image generation of images destined for first and second sides of a printed substrate, with the second clock speed being increased to compensate for substrate shrinkage due to fusing station heating for two-sided printing.
