Abstract: In a digital printing apparatus, such as a xerographic or ink-jet printer, test marks, such as halftone patches or fiducial marks for image registration, are generated on demand. Coordinates of a desired location of the test mark within an imageable area (such as on a print sheet or on a photoreceptor), as well as a selection of the desired type of test mark, are entered through a user interface. Also entered is data about conditions under which image-quality tests using the test marks are to be performed. Information about the test mark and test conditions is retained as a small number of scalar values. The system enables test methods for a machine to be changed easily, and a basic set of system software can be readily applied to different types of printing hardware.

Abstract: A system architecture for scanned non-linearity correction in a printer uses any raster output scanner having scanned non-linearity profile previously stored in memory from a test station installed with any pixel board. The pixel board includes a correction table register wherein the pixel board utilizes the scanned non-linearity profile of the raster output scanner to calculate the correction table register to correct for pixel misregistration.

Abstract: A method and system for repositioning a mark (105,110) on a belt (100) after an image on paper registration process, which includes printing a test pattern, measuring at least one test pattern parameter, detecting a mark on the belt and detecting at least one imaging error associated therewith, using the at least one test pattern parameter and the at least one imaging error to determine the lateral distance required to shift a particular image to a desired location (115,120) on the belt, and shifting the image to the desired location.

Abstract: PROBLEM TO BE SOLVED: To provide a system architecture of nonlinearity correction in which "the mix and match" is given to an ROS and a pixel board adopted at random in manufacturing a printing system. SOLUTION: The system architecture for correcting the nonlinearity of scanning line in a printer uses an arbitral raster output scanner in which a nonlinear profile from a test station fitted on an arbitral pixel board is preliminarily stored in a memory. The pixel board includes a correction table resistor, and the pixel board calculates a correction table resister by making use of the scanning nonlinearity profile of the raster output scanner and corrects the deviation of position of pixels.
