    摘要： The method and equipment for detangling individual jets in an ink jet print station utilizes a reservoir containing fluid and a printhead. The printhead has a drop generator, an orifice structure connected to the drop generator for forming numerous jets, a catcher connected to the drop generator; and a charge device secured to the catcher. A fluid supply system is connected between the printhead and the reservoir. A controller and numerous actuators are connected to the drop generator, and adapted to vibrate the drop generator. A fluid pump is connected to the fluid supply line, is operated by the controller, and is adapted to raise the pressure on the drop generator to at least an operating pressure and lower the pressure on the drop generator to a minimal pressure to prevent entanglement of the jets.

    摘要： An ink jet print station with improved start-up reliability includes an ink reservoir and a printhead. The printhead has at least two drop generators, a return line connected to the generator's fluid ports, an orifice plate connected to the drop generator for forming jets, at least two filters, a controller for operating the valves to control flow, and an ink pump. The ink pump is adapted to move ink from the reservoir to the printhead. Upon startup, fluid is applied independently to the first filter and then the second filter. A method for at least partially filling filters in an ink jet uses the ink jet print station with improved start up reliability.

    摘要： A shutdown procedure is provided for removing all solvent ink from the printhead of an ink jet printer system that uses volatile ink for printing a shutdown method is provided for an inkjet printer that uses volatile inks for printing. Initially, a colorless flush fluid is provided which readily dissolves the ink. The flush fluid is crossflushed through the drop generator and caused to weep out of the orifices in the drop generator to dissolve and rinse away ink residues from the charge plate and the exterior of the orifice plate. The flush fluid is used to rinse off charging electrodes of the charge plate, the catcher face, and the catcher return line. Fluid crossflushed through the drop generator cleans the interior of the drop generator and cleans the crossflush valve.

    摘要： In a continuous ink jet printing apparatus, an ink circulating system allows maintenance of the ink supply reservoir at approximately atmospheric pressure while providing for positive withdrawal of ink from the catcher and/or print head outlet of the apparatus. The system is operable with a single pump. To achieve such positive withdrawal of ink, elements are provided in a bypass line extending from the supply pump outlet to the atmospheric region of the ink reservoir or in the passage from that region of the ink reservoir to the pump intake line, for generating a region(s) of sub-atmospheric pressure, and such region(s) are coupled to the catcher and/or print head outlet.

    摘要： An ink jet printer includes a fluid supply system for supplying ink through the print head of the printer. The fluid supply system includes a pump arrangement supplying ink to the print head from a supply tank via a fluid supply line. A plurality of ink return lines are connected between the pump outlet and the pump inlet. Each of the ink return lines includes a flow restriction, with the flow restriction in each line providing a fluid flow impedance which differs from the impedances provided by the other flow restrictions. A valve arrangement connects the pump outlet to selected ones of the ink return lines, to provide means for controlling the flow rate of ink supplied through the ink supply line to the print head. During periods in which the printer is shut down, a substantially reduced ink flow through the print head is continuously maintained at a reduced fluid flow rate and at a reduced fluid pressure.
