摘要： A continuous ink jet print head is formed of a silicon substrate that includes integrated circuits formed therein for controlling operation of the print head. An insulating layer or layers overlies the silicon substrate and has a series or an array of nozzle openings or bores formed therein along the length of the substrate and each nozzle opening is formed in a recess in the insulating layer or layers by a material depletion process such as etching. The process of etching defines the nozzle openings at locations where heater elements are formed in the insulating layer or layers during a conventional CMOS processing of the integrated circuits. The print head structure thereby provides for minimal post processing of the print head after the completion of the CMOS processing.

摘要： A continuous ink jet print head is formed using a combination of traditional CMOS technology to form the various controlling electrical circuits on a silicon substrate having insulating layer(s) which provide electrical connections and a MEMS technology for forming, nozzle openings. A blocking structure is formed in the insulating layer(s) between a first ink channel formed in the silicon substrate and a second ink channel formed in the insulating layer(s). The blocking structure causes ink to flow around the blocking structure and thereby develop lateral flow components to the liquid entering the second channel so that, for droplets selected for printing, as the stream of droplets emanates from the bore of the nozzle, there is provided a reduced amount of heat needed for operating a heating element adjacent each nozzle opening.

摘要： An imaging apparatus capable of inhibiting inadvertent ejection of a satellite ink droplet and method of assembling same. The imaging apparatus comprises a print head transducer including a pair of sidewalls defining a chamber therebetween, the channel having the ink body disposed therein. The transducer is in fluid communication with the ink body for inducing a first pressure wave in the ink body in order to eject an ink droplet. A waveform generator is connected to the transducer for supplying voltage waveforms to the transducer, so that the transducer induces pressure waves in the ink body. However, the first pressure wave has a reflected portion formed by the first pressure wave reflecting from the sidewalls. The reflected portion is sufficient to otherwise inadvertently eject unintended satellite ink droplets. Thus, a sensor is in fluid communication with the ink body for sensing the reflected portion and is connected to the transducer for inducing a second pressure wave in the ink body. The second pressure wave has an amplitude and phase damping the reflected portion of the first pressure wave in order to the inhibit inadvertent ejection of satellite ink droplets.

摘要： Pagewidth image forming system and method. The system features a plurality of mechanically isolated transducers capable of pressurizing an ink body associated with each of plural nozzle so that an ink meniscus extends from the ink body. The transducers are operated such that the ink bodies are uniformily intermittently pressurized. An ink droplet separator is also provided for lowering surface tension of the meniscus. In this regard, the droplet separator lowers the surface tension of the meniscus at a selected nozzle as the meniscus extends from the ink body, so that the meniscus forms a neck portion thereof. The extended meniscus severs from the ink body at the neck portion as the droplet separator lowers the surface tension to a predetermined value so as to form an ink droplet.

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.
