摘要： Apparatus for controlling ink in an ink jet printer includes an ink delivery channel; a source of pressurized ink communicating with the ink delivery channel; a nozzle bore which opens into the ink delivery channel to establish an ink flow path, the nozzle bore defining a nozzle bore perimeter, inherent surface tension of pressurized ink in the nozzle bore forming an ink meniscus; and a selectively-actuated heater associated with the nozzle bore to cause a reduction in the surface tension of the ink when activated such that ink flows from the nozzle bore in a continuous stream substantially for the duration of activation of the heater only.

摘要： Imaging apparatus and method adapted to control ink droplet volume and void formation. The apparatus (10) includes an ink jet print head (45) having a nozzle (110) for ejecting an ink droplet (150) therefrom. A heater element (130) is in heat transfer communication with the ink droplet for variably supplying heat energy to the ink droplet, so that the volume of the ink droplet is controlled as the heat energy is variably supplied to the ink droplet. A controller (40) is connected to the heater element for variably controlling the heat energy supplied to the ink droplet. The controller variably controls the heat energy by variably controlling a plurality of voltage pulses sequentially supplied to the heater element. Moreover, in order to reduce the potential for void formation in the ink droplet, the pulses are spaced-apart by a predetermined delay interval. Suitable control of ink droplet volume and delay interval between pulses results in uniform print density and "gray-scaling" of each dot or pixel in the output image and also precludes void formation.

摘要： A facsimile machine having a print head comprising: (1) a plurality of drop-emitter nozzles; (2) a body of ink associated with said nozzles; (3) drop selection means for selecting predetermined nozzles and generating a difference in meniscus position between ink in selected and non-selected nozzles; and (4) drop separating means for causing ink from selected nozzles to separate as drops from the body of ink, while allowing ink to be retained in non-selected nozzles. A customized magazine and information distribution system which uses a color facsimile machine as the information delivery system. Daily news and other updated information is matched against a customer information request profile on a daily basis. This information is transmitted overnight to the customers facsimile machine, which uses a concurrent drop selection and drop separation drop on demand printing mechanism.

摘要： Ink is contained under pressure in an ink reservoir. The ink travels to a nozzle, where it is retained in the nozzle by the ink surface tension. An equilibrium is created whereby no ink escapes the nozzle by ensuring that the ink pressure, plus a predetermined external electrostatic or magnetic field, is insufficient to expel the ink from the nozzle. The system can include a heater which is incorporated at the tip of the nozzle. When this heater is energized by a heater control circuit, the ink in contact with the nozzle tip is heated. Convection rapidly transports the heat over the ink meniscus. The ink is formulated so that surface tension reduces with increasing temperature. At an elevated temperature, the surface tension of the ink is reduced sufficiently that the equilibrium is broken, and ink moves out of the nozzle. At a predetermined time, the heater is turned off by the heater control circuit and the falling temperature causes the surface tension to increase. Ink continues to move out of the nozzle by its own momentum. Surface tension and the viscous flow limitation of the nozzle causes the ink drop to 'neck' and separate from the body of ink. The ink drop then travels to the recording medium. The thermal drop on demand mechanism operates at low power, making construction of monolithic multiple nozzle print heads using a modified CMOS process practical. The print heads can include extensive fault tolerance to improve yield, device life, and reliability.
