    摘要: The present invention resides in a self-cleaning printer with a print head having an orifice plate defining an ink jet orifice, a cleaning orifice and a drain orifice. The orifice plate further defines an outer surface between the orifices. A source of pressurized cleaning fluid is connected to the cleaning orifice and a fluid return is connected to the drain orifice for storing used cleaning fluid. A cleaning surface is disposed adjacent to and separate from the outer surface to define a capillary fluid flow path from the cleaning orifice across the ink jet orifice and to the drain orifice. During cleaning, the source of pressurized cleaning fluid discharges a flow of a cleaning fluid into the capillary fluid flow path and pressurized cleaning fluid from the capillary flow path passes through the drain orifice and into the fluid return.

    摘要: A continuous ink jet apparatus is provided. The printhead includes a nozzle array with portions of the nozzle array defining a length dimension. A drop forming mechanism is positioned relative to the nozzle array. The drop forming mechanism is operable in a first state to form ink drops having a first volume travelling along a path and in a second state to form ink drops having a second volume travelling along the path. A system applies force to the ink drops travelling along the path. The force is applied in a direction such that the ink drops having the first volume diverge from the path and at least one of the ink drops having the first volume and the ink drops having the second volume are displaced relative to the length dimension.

    摘要: A pump(10) for pumping various primary fluids includes a body(100) having a primary fluid channel(110) defined therein, and a primary fluid supply is coupled to the primary fluid channel to supply a primary fluid to the primary fluid channel. A mechanism(130/132) is provided for introducing a secondary fluid to an interface region of the primary fluid channel to thereby define a fluid interface between the primary fluid and the secondary dry fluid in the interface region. An energy delivery(150/160) device delivers energy to the interface region to create a thermal gradient along the fluid interface. The thermal gradient results in a surface tension gradient along the interface. The primary fluid will move to compensate for the surface tension gradient.
