Abstract
A technique is described for determining pixel dropout in a printhead that has a plurality of print elements arrayed along an axis. In the technique, a dataset of integrated intensity values, in the printing direction on a substrate, of a captured image is generated and used to determine if pixel dropout has or may have occurred.
