Abstract
Cross-track spacing variations for a plurality of printer subsystems of an electrophotographic printing system are characterized by printing first and second test pattern and capturing image of the printed test patterns. The first and second test patterns are chosen so that the printed test patterns respond differently to cross-track spacing variations in different printer subsystems. The first and second digitized test patterns are analyzed to determine parameters that characterize an attribute of the printed test pattern as a function of cross-track position. A first defect model is used to determine estimated cross-track spacing variations for one or more printer subsystem as a function of the determined parameters.
