  • Misprint detection techniques
    Patent number: 6039429
    Abstract: Disclosed is a combined "streak-detector" and "ink-lever flow detector" on opposite sides of a single printed circuit board; each detector comprising a pair of parallel printed circuit segments adapted to be "shorted" by interposition of conductive ink and coupled to register this event in an associated detect-logic stage.
    Type: Grant
    Filed: August 23, 1998
    Date of Patent: March 21, 2000
    Assignee: Unisys Corporation
    Inventor: Andrew J. Balousek
