Abstract

A method of printer operation enables visual detection of defective inkjets. The method includes operating inkjets in a predetermined number of printheads that eject a same color of ink to form a test pattern having three portions. One portion is printed by the even-numbered inkjets in each printhead, one portion is printed by the odd-numbered inkjets in each printhead, and a third portion is printed by all of the inkjets in each printhead. The portions are printed immediately adjacent to one another in a process direction with the third portion between the other two portions.
