A method and apparatus for analyzing images deposited on an image receiving member of a printer, and more particularly analyzing images deposited on a surface of an imaging drum in an inkjet printer. A photoelectric sensor supported by a sled in contact with the surface of the imaging drum can be used to detect missing jets in the printhead, to align the printhead, to reduce the amount of purged ink, and to determine run out of the imaging drum.
