ABSTRACT:
A modular print head system for continuous ink jet printer apparatus includes a droplet stream generator, a droplet charger and a droplet catcher constructed as a module that includes ink supply and return line coupling devices, each having engagement openable valves, resonator and charge plate connectors, and index surfaces for accurately positioning of the module. A nest assembly of the system includes ink supply and return ports, droplet generator and charging power terminals, structure for supporting and accurately positioning a print head module. The nest assembly further includes a camming device which is movable to engage a supported module into an operative relation with the ink lines coupled to the ports, the valves open, the droplet generator and charger connected and to nest power terminals and the module index surfaces in contact with the positioning structure of the nest assembly.
