Abstract

A method of calibrating individual elements of an ionographic image bar and related devices that provides corrections allowing a uniform printout from the entire array is disclosed. The method is comprised of the steps: (1) printing a pattern on a copy sheet where the measured reflectivity decreases stepwise in the process direction; (2) scanning the print density from each imaging elements; and (3)
