    摘要： An inkjet print cartridge uses at least one groove to supply ink from an ink reservoir to the fluid channel, which includes an ink ejection chamber, such that foreign particles within the ink supply are filtered out by the grooves so as not to block the fluid channel. In one embodiment, a barrier layer between a substrate and nozzle member contains the ink ejection chamber which is in communication with a plenum via a flow restrictor, such as pinch points. The nozzle member includes an array of orifices and grooves. The substrate includes two linear arrays of ink ejection elements, such as heater elements, and each orifice in the nozzle member is associated with an ink ejection chamber and ink ejection element. A plurality of grooves is likewise associated with each plenum. The plurality of grooves in the nozzle member supply ink into each plenum, which in turn supplies ink to the ink ejection chamber.

    摘要： Disclosed is an ink delivery system for high throughput commercial inkjet printing devices. The ink delivery system includes a high speed ink ejection printhead with a large number of nozzles and an ink flow design which provides for improved printhead cooling. The printhead design achieves high ink ejection rates by having a very short inlet channel length which is made possible by having nozzles with a constant distance from the edge of the printhead. In order to accommodate this constant distance from the edge of the printhead the entire array of nozzles is disposed at a angle relative to the direction normal to the scan direction. An impinging ink flow against the back of the printhead is provided to limit the temperature of the printhead. A bubble collection chamber to increase the life of the printhead and a pressure regulator to provide ink at a controlled pressure to the printhead may also be provided. Pressurized ink may be provided so that ink pressure may be properly controlled even during peak usage.

    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 over-damped. 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 iso-propyl 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，高速补充的特征是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。 快速干燥时间是通过醇，如异丙醇与4或5碳醇或与异丙醇加表面活性剂的组合来实现的。 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 including 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 said 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 defined by a barrier layer for each firing chamber connecting the secondary channel with the firing chamber for allowing high frequency refill of the firing chamber. The separate inlet passage for each firing chamber having peninsulas and pinch points formed in the barrier layer to prevent cross-talk and overshoot during high frequency operation. A group of the firing chambers in adjacent relationship forming a primitive in which only one firing chamber in said primitive is activated at a time. A first circuit on said substrate connect to the firing elements and a second circuit on the cartridge connect to the first circuit, for transmitting firing signals to the ink firing elements at a frequency greater than 9 kHz. The preferred configuration of the nozzle member, ink channels, and vaporization chambers allows a printing resolution of 600 dpi and a firing rate of greater than 9 kHz.

    摘要： Multi-color ink-jet pens having an orifice set associated with each color are primed by an apparatus that avoids mixing of two colors during priming. A resilient seal forms a chamber that encloses the orifice sets. The chamber is connected to a vacuum source to reduce the pressure in the chamber for drawing ink out of the orifices. A set of suction tubes connects to the vacuum source, with each tube terminating within the chamber in closely spaced relation with a corresponding orifice set for drawing excess ink away from the orifice set, thereby preventing the various colors of primed ink from mixing.

    摘要： An inkjet printer cartridge adapted for enhanced cleaning thereof, and method of assembling the printer cartridge. An inkjet printer cartridge comprises a cartridge body defining a chamber therein. A substrate is coupled to the cartridge body and has a hole therethrough in communication with the chamber. An orifice plate is coupled to the substrate and has an orifice therethrough aligned with the hole. A platform is coupled to the substrate and surrounds the orifice plate. The platform defines a relatively smooth surface thereon having a predetermined surface roughness for sealably engaging a cap belonging to a print head cleaning service station movable into engagement with the printer cartridge. The surface of the platform may have a surface roughness of between approximately 0.5 microinches and approximately 2.0 microinches. Moreover, the surface of the platform is also level for sealably engaging the cap.
