Abstract

See full text

A method for printhead location identification includes identifying a plurality of amplitudes for a portion of pixel columns in image data generated from a portion of an image receiving surface in which marks formed by an inkjet in the printhead are printed. The amplitudes are generated from a portion of each pixel column including expected locations for a portion of the printed marks in a process direction. The method further includes identifying a cross-process location of the inkjet from a pixel column corresponding to a pixel column with a maximum local amplitude value and storing the location of the inkjet in a memory for printhead registration.
