摘要： This invention provides an improved ink flow path between an ink reservoir and vaporization chambers in an inkjet printhead. In the preferred embodiment, a barrier layer containing ink channels and vaporization chambers is located between a rectangular substrate and a nozzle member containing an array of orifices. The substrate contains two linear arrays of heater elements, and each orifice in the nozzle member is associated with a vaporization chamber and heater element. The ink channels in the barrier layer have ink entrances generally running along two opposite edges of the substrate so that ink flowing around the edge of the substrate gain access to the ink channels and to the vaporization chambers.

摘要： An inkjet printhead includes a compact substrate of increased stability and structural integrity to provide a high resolution 600 dot-per-inch nozzle array having a one-half inch swath. A plurality of ink vaporization chambers are respectively aligned with the nozzles in two longitudinal columns, one column extending longitudinally along one edge of the substrate and a second column extending longitudinally along an opposite edge of the substrate, with ink feed channels communicating through an ink passage from an underside of the substrate around both edges of the substrate to the vaporization chambers. The ink feed channels have thereby been eliminated from the central portion of the substrate, and replaced by the ink feed channels at the edges of the substrate.

摘要： An inkjet drop ejection system comprises a combination of printhead components and ink, mutually tuned to maximize operating characteristics of the printhead and print quality and dry time of the ink. Use of a short shelf (distance from ink source to ink firing element), on the order of 55 microns, provides a very high speed refill. However, it is a characteristic of high speed refill that it has a tendency for being overdamped. To provide the requisite damping, the ink should have a viscosity greater than about 2 cp. In this way, the ink and architecture work together to provide a tuned system that enables stable operation at high frequencies. One advantage of the combination of a pigment and a dispersant in the ink is the resultant higher viscosity provided. The high speed would be of little value if the ink did not have a fast enough rate of drying. This is accomplished by the addition of alcohols or alcohol(s) and surfactant(s) to the ink. Fast dry times are achieved with a combination of alcohols, such as isopropyl alcohol with a 4 or 5 carbon alcohol or with iso-propyl alcohol plus surfactant(s). One preferred embodiment of a short shelf (90 to 130 microns), ink viscosity of about 3 cp, and surface tension of about 54 provides a high speed drop generator capable of operating at about 12 KHz. Reducing the shelf length to about 55 microns, in combination with rotating the substrate at an angle to the scan direction, permits maximum drop generator operation as high as about 20 KHz. As a consequence of employing pigment-based inks, high optical densities are realized, along with excellent permanence (no fade and better waterfastness), and good stability. The combination of preferred ink and pen architecture provides good drop generator stability.
摘要翻译：喷墨墨滴喷射系统包括打印头部件和油墨的组合，其相互调节以最大化打印头的操作特性以及油墨的打印质量和干燥时间。使用大约55微米的短搁架（墨水源到墨水喷射元件的距离）提供了非常高的速度补充。然而，它具有高速补充的特点，它具有过度阻尼的倾向。为了提供必要的阻尼，油墨的粘度应大于约2cp。以这种方式，墨水和结构共同工作，提供了一个可在高频下稳定运行的调谐系统。油墨中颜料和分散剂的组合的一个优点是得到较高的粘度。如果墨水没有足够的干燥速度，高速度就没有什么价值。这通过向油墨中加入醇或醇和表面活性剂来实现。快速干燥时间通过醇，例如异丙醇与4或5个碳醇或与异丙醇加表面活性剂的组合来实现。短架（90-130微米），油墨粘度约为3cp，表面张力约为54的一个优选实施例提供了能够在约12KHz下操作的高速液滴发生器。将搁板长度减小至约55微米，与基板以扫描方向成一定角度的旋转结合使得最大的液滴发生器运转高达约20KHz。作为使用颜料基油墨的结果，实现了高的光密度，以及优异的耐久性（不褪色和更好的耐水性）和良好的稳定性。优选的墨水和笔结构的组合提供了良好的液滴发生器稳定性。

摘要： Disclosed is an inkjet print cartridge having an ink reservoir; a substrate having a plurality of individual ink firing chambers with an ink firing element in each chamber along a top surface of the substrate and having a first outer edge along a periphery of substrate; the first outer edge being in close proximity to the ink firing chambers. The ink firing chambers are arranged in a first chamber array and a second chamber array and with the firing chambers spaced so as to provide 600 dots per inch printing. An ink channel connects the reservoir with the ink firing chambers, the channel including a primary channel connected at a first end with the reservoir and at a second end to a secondary channel; the primary channel allowing ink to flow from the ink reservoir, around the first outer edge of the substrate to the secondary channel along the top surface of the substrate so as to be proximate to the ink firing chambers. A separate inlet passage for each firing chamber connecting the secondary channel with the firing chamber for allowing high frequency refill of the firing chamber. A group of the firing chambers in adjacent relationship forming a primitive in which only one firing chamber in the primitive is activated at a time. First circuit member on the substrate connects to the firing elements and a second circuit member on the cartridge connects to the first circuit member, for transmitting firing signals to the ink firing elements at a frequency greater than 9 kHz.

摘要： In a print cartridge according to the preferred embodiment of the invention, a polymer tape having orifices formed therein and containing conductive traces has a substrate containing heater elements affixed to a back surface of the tape. Each of the heater elements in the substrate is located substantially behind each of the orifices. The edges of the nozzle member overlap the edges of the substrate, and the back surface of the tape is sealed with respect to an ink reservoir so that a seal substantially circumscribes the substrate. This allows ink to flow around the side edges of the substrate and into vaporization chambers associated with each orifice. The conductive traces on the tape are attached to electrodes along the shorter side edges of the substrate so as not to interfere with the edge-feed of ink along the longer edges of the substrate. A demultiplexer on the substrate requires relatively few electrodes to be formed on the substrate for supplying energization signals to the numerous heater elements formed on the substrate.
