Abstract

Printhead longevity is extended by more uniformly utilizing individual printhead printing elements. A preferred algorithm moves an active zone of printing elements uniformly down the printhead on successive print passes. If insufficient printing elements are available to print the next pass, the active zone is moved to a point near the top of the printhead determined by a modulo function.
