    摘要： A thermal ink-jet printhead includes ejectors which define channels for the passage of liquid ink therethrough. A heating element (60) for nucleating liquid ink is disposed in a heating portion (20) of each channel. A nozzle portion (22) of the channel is smaller in cross-sectional area than the heating portion (20), and a manifold portion (24), through which new liquid ink enters the heating portion (20), is larger in cross-sectional area than the heating portion (20). The design is advantageous for ejecting inks of viscosity greater than 2 centipoise.

    摘要： A heater element for a printhead for an ink jet printing system has a pit layer (22) which protects the overglaze passivation layer (20), PSG step region (10), portions of the Ta layer (14) and dielectric isolation layer (12) and junctions or regions susceptible to the cavitational pressures. The inner walls (23) of the pit layer define the effective heater area and dopant lines (9) within the heater resistor (8) define the actual heater area. In an alternative arrangement, the dopant lines define both the actual and effective heater areas, and in yet another arrangement, one inner wall and one dopant line define the effective heater area. When a plurality of the heater elements are incorporated into a printhead having either full pit channel geometry and open pit channel geometry, the operating lifetime of the printhead is extended because the added protection of the pit layer prevents : 1) passivation damage and cavitational damages of the heater elements ; and 2) degradation of heater robustness, hot spot formations and heater failures well into the 109 pulse range. The printhead can be incorporated into a drop-on-demand printing system of a carriage type or a full width type.

    摘要： An ink jet ink includes a colorant and a liquid component containing at least one of an epoxy and a vinyl ether. Water may also be dissolved in the liquid component. Preferably, the vinyl ether is ethylene glycol monovinyl ether. An ink jet recording process includes the steps of ejecting an ink jet ink, such as the inks of the present invention, from an orifice to form an image on a recording medium.
