A continuous ink jet print head, including: a droplet generator (&#x2033;) for generating ink droplets (); a charging electrode (&#x2033;) having a passageway (&#x2033;) through which the ink droplets travel to receive a charge; a deflection electrode (&#x2033;) for deflecting the charged ink droplets; a gutter ('&#x2033;) having a gutter entrance (&#x2032;&#x2033;); wherein the passageway is aligned with the gutter entrance through which uncharged droplets enter; and a mounting deck (&#x2033;) configured to secure the gutter entrance into a fixed, nonadjustable gutter entrance position (&#x2032;&#x2033;) and to secure the charging electrode into a fixed, nonadjustable charging electrode position (&#x2033;) relative to the gutter entrance.

Continuous ink jet print head with zero adjustment embedded charging electrode

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.
