Abstract
A continuous stream ink jet print head comprising: a droplet generator () for generating a continuous stream of ink droplets; a charging electrode () for selectively charging the ink droplets; deflection electrodes () for deflecting the charged ink droplets; and a catcher () for collecting uncharged ink droplets, wherein the deflection electrodes are contained within a surrounding structure () that both (i) provides surfaces () which are contoured to the shape of the main bodies of the deflection electrodes such that the main bodies may be mounted against the surfaces to correctly position the deflection electrodes within the print head, and (ii) serves as a manifold for fluid in operation of the print head, wherein the print head includes a cover () for the surrounding structure, the cover forming a wall of the space between the deflection electrodes, the wall extending along the stream of ink droplets.
