INK JET PRINTING APPARATUS WITH INTEGRAL DEFLECTOR

摘要

A continuous stream ink jet printer is provided having an ink droplet forming mechanism for ejecting a stream of ink droplets having a selected one of at least two different volumes toward a print medium and a droplet deflector and ink conduit which are integrally formed to the printhead for producing a flow of gas that interacts with the ink droplet stream to separate droplets having different volumes and collects all droplets not used for printing. The provision of integrally forming the gutter system with the droplet forming mechanism eliminates the requirement to align an external gutter system upon full print engine assembly.
