Abstract: A system architecture for scanned non-linearity correction in a printer us es 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 correcti on table register to correct for pixel misregistration.

Abstract: A reference frequency and facet to facet correction circuit utilizes a phase locked loop which includes a digital phase detector to measure the time difference between the end of scan (EOS) and the end of count (EOC) of each facet and store them in a lookup table. The phase locked loop continuously generates an average time value form the time differences of all the facets of the polygon. The phase locked loop also adds the errors of each facet to the average time value and uses the result to correct the frequency of a pixel clock generator for both the reference frequency and facet to facet errors.

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.

Abstract: PROBLEM TO BE SOLVED: To provide a circuit which corrects a reference frequency error and errors for every facet by using a phase-locked loop. SOLUTION: The phase-locked loop includes a digital phase detector whish measures the time differences between the ends of scanning of each facet and the ends of counting and stores them in a look-up table. The phase-locked loop generates a mean time value continuously from the time differences of all the faucets of a polygon. Further, the phase-locked loop adds errors of each facet to the mean time value and uses the result to correct the frequency of a pixel clock generator for both the reference frequency error and the errors for every facets.
