摘要： Apparatus for controlling ink in a continuous ink jet printer includes an ink delivery channel; a source of pressurized ink communicating with the ink delivery channel; a nozzle bore which opens into the ink delivery channel to establish a continuous flow of ink in a stream, the nozzle bore defining a nozzle bore perimeter; a drop generator which causes the stream to break up into a plurality of drops at a position spaced from the ink stream generator; and a drop deflector. The drop generator includes a heater having a selectively-actuated section associated with only a portion of the nozzle bore perimeter, whereby actuation of the heater section produces an asymmetric application of heat to the stream to partially control the direction of the stream. The drop deflector includes a gas flow source producing an additional control to the stream between a print direction and a non-print direction.

摘要： A drop deflector apparatus for a continuous drop emission system that deposits a liquid pattern on a receiver according to liquid pattern data comprising a plurality of drop nozzles formed along a nozzle array axis and emitting a plurality of continuous streams of a liquid that breaks up into a plurality of streams of drops having nominal flight paths that are substantially parallel and substantially within a nominal flight plane is disclosed. An airflow plenum having an evacuation end connected to a negative pressure source and an impingement end having an opening located adjacent the nominal flight plane into which ambient air is drawn for the purpose of deflecting drops in an air deflection direction perpendicular to the nominal flight plane is provided. The opening is bounded by upstream, downstream, first and second walls wherein the upstream and downstream wall ends are spaced away from the nominal flight plane in the air deflection direction by a larger amount than are the first and second side wall edges. An airflow plenum having through slots for the passage of drops is also disclosed. Such a plenum design increases the amount of drop deflection achieved for a given maximum deflection air velocity and provides a reduction in the affect of perturbing air currents that may be present around the nominal flight paths. Drop synchronization apparatus is disclosed to break up continuous streams into drops of large and small volumes according to liquid pattern data, the large and small drops being differently deflected by the air flow in the airflow plenum. A plurality of path selection elements is disclosed for directing drops along different paths according to liquid pattern data, wherein drops following different paths are differently deflected by the air flow in the airflow plenum. A method of printing using the disclosed apparatus is also disclosed.

摘要： An apparatus for printing an image is provided. The apparatus includes a droplet forming mechanism operable in a first state to form droplets having a first volume travelling along a path and in a second state to form droplets having a plurality of other volumes travelling along the same path. A droplet deflector system applies force to the droplets travelling along the path. The force is applied in a direction such that the droplets having the first volume diverge from the path while the droplets having the plurality of other volumes remain travelling substantially along the path or diverge slightly and begin travelling along a gutter path.
