Abstract
Systems and methods are provided for print verification that reports defective printheads. One embodiment is a Print Verification System (PVS) that includes an interface to receive print data, and an imaging device to obtain image data of printed output of the print data. The PVS also includes a processor to detect a print error on a page by comparing the print data and the image data. The processor determines a lateral distance of a location of the print error with respect to an edge of the page, identifies a print engine that printed the page, determines a lateral offset of the print engine with respect to the edge of the page, identifies a printhead among a plurality of printheads of the print engine that caused the print error based on the lateral distance of the print error and the lateral offset of the print engine.
