摘要： A continuous ink jet printing system using asymmetrical heating of the fluid in which the nozzle bore (46, 76, 78) of the printhead preferably has a non-circular opening. The nozzle bore (46, 76, 78) has reflection symmetry about the long axis of its cross-section and may be, for example, elliptical or rectangular. In the preferred embodiment of the invention, the nozzle bore (46, 76, 78) has an aspect ratio greater than unity, wherein the aspect ratio is defined as the ratio of the long axis length to the short axis length.

摘要： A continuous inkjet printer in which a continuous ink stream is deflected at the printhead nozzle bore without the need for charged deflection plates or tunnels. The printhead includes a primary ink delivery channel which delivers a primary flow of pressurized ink through an ink staging chamber to the nozzle bore to create an undeflected ink stream from the printhead. A secondary ink delivery channel adjacent to the primary channel is controlled by a thermally actuated valve to selectively create a lateral flow of pressurized ink into the primary flow thereby causing the emitted ink stream to deflect in a direction opposite to the direction from which the secondary ink stream impinges the primary ink stream in the ink staging chamber. A method of fabricating the printhead includes layering of the thermally actuated valve over the secondary ink delivery channel formed in a silicon substrate and creating the ink staging chamber over the delivery channels with sacrificial material which is later removed through the nozzle bore etched into the chamber wall formed over the sacrificial material.
