Abstract
A non-impact printer apparatus includes a printhead having a plurality of recording elements. Nonuniformities in emission characteristics of the recording elements are corrected using look-up tables (LUT) assemblages that include a first LUT wherein the recording elements are binned in accordance with bin values associated with their emission characteristics and a second LUT wherein bin values, output from the first LUT are used to address various tables providing exposure correction. The first and second LUTs are advantageously dual port RAM devices that allow operation during printing while simultaneously allowing loading of data into the tables for use for subsequent printing. Thus, process conditions may be continually monitored and correction data updated without delaying of current printing which may occur using correction data already stored in the LUT assemblages.
