摘要： An actively-controlled recirculating ink delivery system is provided that incorporates active control of pressures downstream of the printhead. This is achieved through the use of a device (such as a pump, return valve, combination thereof or similar devices) that provides active control of downstream ink pressures. A pressurized ink supply, pressure sensors, an air and heat exchanger are also provided, thereby improving start up, normal operation, purging and shut down procedures. Because the pressurized ink supply is not restricted to sit at a particular vertical distance below the printhead, backpressure may be changed quickly and easily through electronic control, and system priming is considerably quicker than with conventional air-pressurized systems.

摘要： A system for receiving and recycling ink comprises a print cartridge having a printhead, and an ink supply reservoir fluidly connected to the print cartridge and a seal member coupled to the ink supply reservoir. The seal member defines a fluid path into the reservoir and the print cartridge engages the seal member so that ink spit from the printhead flows through the fluid path into the reservoir.

摘要： A printhead for an inkjet printer employs asymmetric orifices, such as an egg-shaped orifice, at the surface of the orifice plate to cause the ink drop tail to be severed at a predictable location from the orifice. The controlled tail and diminished spray of an ink droplet expelled from the asymmetric orifice results in improved edge roughness and improved quality of print.

摘要： A pressure regulator that sets the pressure of a liquid to a predetermined pressure differential below a reference pressure, such as atmospheric pressure. The pressure regulator comprises a liquid delivery channel and a capillary array. The liquid delivery channel includes a liquid input and a liquid output. The liquid flows through the liquid delivery channel from the liquid input to the liquid output. The capillary array is composed of ones of an elongate capillary. The capillary includes a first end in fluid communication with the liquid delivery channel and a second end in pressure communication with a source of the reference pressure. The liquid flows through the first end into the capillary to form a liquid surface in the capillary. The second end is remote from the first end. The capillary has cross-sectional dimensions in relation to the surface tension of the liquid and the angle of contact between the liquid and the capillary such that the pressure drop across the liquid surface in the capillary is equal to the predetermined pressure differential.

摘要： A method and apparatus for improving inkjet print quality uses a printhead having an array using a plurality of nozzles in sets in each drop generator mechanism. Where a conventional inkjet pen fires a single droplet of ink at a target pixel per firing cycle, the present invention simultaneously ejects a plurality of droplets at different subdivisions of pixels. Drop generators of a printhead array includes a plurality of nozzles for the drop generators arranged such that the light absorption of the sum of the simultaneously ejected ink droplets is like that of conventionally ejected drops but distributed over an area of the printed medium greater than that of a conventional target pixel.
