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.

A system architecture for scanned non-linearity correction in a printer comprising:
- a raster output scanner having scanned a non-linearity profile stored in a memory;
- and
- a pixel board including a correction table register and a variable frequency clock with a frequency self-calibration circuit;
- and
- a controller that controls said pixel board to self-calibrate the clock frequency, and then utilizes the scanned non-linearity profile of the raster output scanner and a self-calibration curve of the clock frequency to determine a correction for pixel misregistration.
A system architecture for scanned non-linearity correction in a printer comprising:
- a scanner that scans a non-linearity profile for a raster output scanner;
- a memory that stores the non-linearity profile;
- a variable frequency clock with a frequency self-calibration circuit;
- and
- a controller that controls a self-calibration of the clock frequency, and then utilizes the scanned non-linearity profile of the raster output scanner and a self-calibration curve of the clock frequency to determine a correction for pixel misregistration on a pixel board.
A system architecture for scanned non-linearity correction in a printer comprising:
- at least one raster output scanner that scans a non-linearity profile stored in a memory;
- and
- at least one pixel board that includes a correction table register and a variable frequency clock with a frequency self-calibration circuit that calibrates a frequency clock, said at least one pixel board utilizes the scanned non-linearity profile of the at least one raster output scanner and a self-calibration curve of the clock frequency to determine a correction for pixel misregistration.
