Abstract:
A system and method detect missing inkjets in an inkjet image generating system. The system and method generate digital images of printed documents that do not have test pattern data within them. The digital images are processed to detect light streaks and the positions of the light streaks are correlated to inkjet positions in printheads. Identification of the ink color associated with the correlated inkjet positions are obtained with analysis of color separated images and/or color errors.
