Abstract
A continuous ink jet print head (), including: an ink droplet generator () configured to emit an ink droplet () along an undeflected droplet flight path (); a charge electrode () configured to impart a charge to the ink droplet; deflector plates (A,B) adjacent the undeflected droplet flight path, downstream from the charge electrode, and configured to deflect the ink droplet to a deflected droplet flight path that lies within a range of deflected flight paths bounded by at least deflected droplet flight path and a most deflected droplet flight path; a gutter () configured to receive an ink droplet traveling along the undeflected droplet flight path; and an ink buildup sensor () configured to detect an accumulation of ink () relative to a droplet flight path disposed within the range of deflected flight paths.
