    • An improved ink jet printhead comprising upper and lower substrates that are mated and bonded together with a thick film insulative layer sandwiched therebetween. One surface of the upper substrate has etched therein one or more grooves and a recess which when mated with the lower substrate will serve as capillary filled ink channels and ink supply manifold, respectively. The grooves are open at one end and closed at the other. The open ends serve as nozzles. The manifold recess is adjacent the grooved closed ends. Each channel has a heating element located upstream of the nozzle. The heating elements are selectively addressable by input signals representing digitized data signals to produce ink vapor bubbles. The growth and collapse of the bubbles expel ink droplets from the nozzles and propel them to a recording medium. A recess patterned in the thick layer provides a flow path for the ink from the manifold to the channels by enabling the ink to flow around the closed ends of the channels and increase the flow area to the heating elements. Thus, the heating elements lie at the distal end of the recesses so that a vertical wall of elongated recess prevents air ingestion while it increases the ink channel flow area and increases refill time, resulting in an increase in bubble generation rate.
    • 一种改进的喷墨打印头,其包括上下基板,其与夹在其间的厚膜绝缘层配合并结合在一起。 上基板的一个表面在其中蚀刻有一个或多个凹槽和与下基板配合的凹槽,分别用作毛细管填充的墨水通道和墨水供应歧管。 槽在一端敞开,另一端封闭。 开口端作为喷嘴。 歧管凹槽与凹槽的封闭端相邻。 每个通道具有位于喷嘴上游的加热元件。 加热元件可以通过表示数字化数据信号的输入信号来选择寻址,以产生油墨蒸气泡。 气泡的生长和坍塌从喷嘴中排出墨滴并推动它们到记录介质上。 在厚层中图案化的凹槽通过使墨水能够围绕通道的封闭端流动并且增加到加热元件的流动面积而提供用于从歧管到通道的墨水的流动路径。 因此,加热元件位于凹部的远端,使得细长凹槽的垂直壁防止空气摄取,同时增加墨通道流动面积并增加再填充时间,导致气泡产生速率的增加。

    • An ink jet printer is configured in a hybrid architecture wherein a full width printbar is combined with a partial width color scanning assembly to provide the capability of selectively printing in black only or, alternately, of producing color prints by operating the color scan assembly exclusively. The cost of the hybrid system, when compared to a full width color system using four full width printbars, is greatly reduced. Throughput time is reduced by providing the control circuitry for distinguishing between black only and color operation and selectively controlling the printer mode of operation. The hybrid architecture is particularly useful in a LAN system since it provides a mechanism for balancing the relative color versus black page decomposition speed limitations. Also, the hybrid architecture enables a relatively simple implementation of a checkerboarding technique to suppress banding in output prints.
    • 喷墨打印机被配置为混合架构,其中全宽度打印条与部分宽度彩色扫描组合组合,以提供选择性地以黑色打印的能力,或者通过专门操作彩色扫描组件来产生彩色打印。 与使用四个全宽度打印棒的全幅彩色系统相比,混合系统的成本大大降低。 通过提供用于区分黑色和彩色操作的控制电路并选择性地控制打印机操作模式来减少吞吐时间。 混合架构在LAN系统中特别有用,因为它提供了用于平衡相对颜色与黑色页面分解速度限制的机制。 此外,混合架构使得能够相对简单地执行棋盘棋技术来抑制输出打印中的条带。

    • Modular partial bars include a substrate bar having a length and a plurality of printhead subunits attached to only one side of the substrate bar, each printhead subunit being spaced from an adjacent printhead subunit. These modular partial bars are used as building blocks to form full width staggered array printheads. When the printhead subunits are arranged on each substrate bar so that two substrate bars are capable of forming a full width staggered array printhead, each modular partial bar is referred to as a modular half bar. One modular half bar can be stacked on another modular half bar any number of ways. For example, two half bars can be stacked with their printhead subunit containing sides facing the same direction, away from one another or towards one another. When two half bars are stacked with their printhead subunit containing sides facing in the same direction, an ink manifold for supplying ink to the printhead subunits of the lower half bar can be provided in the substrate of the upper half bar. When half bars are arranged with their printhead subunit containing sides facing each other, a common ink supply manifold can be used to supply ink to all of the printhead subunits in the full width staggered array, thus eliminating the need for two separate ink supply manifolds. By modifying the construction of the channel plates typically used to form the printhead subunits, the need for a separate ink supply manifold can be entirely eliminated.
    • 模块化部分棒包括具有长度的衬底条和仅附接到衬底条的一侧的多个打印头子单元,每个打印头子单元与相邻的打印头子单元间隔开。 这些模块化部分棒用作构建块以形成全宽度交错阵列打印头。 当打印头子单元布置在每个基板上时,使得两个基板条能够形成全宽度交错阵列打印头,每个模块化部分条被称为模块化半条。 一个模块化的半棒可以堆叠在另一个模块化的半棒上任意数量的方式。 例如,两个半棒可以堆叠,其打印头子单元包含侧面朝向相同的方向,彼此远离或彼此朝向彼此。 当两个半棒堆叠而其打印头子单元包含侧面朝向相同方向时,可以在上半杆的基板中提供用于向下半杆的打印头子单元供墨的墨水歧管。 当半棒布置成其打印头子单元包含侧面彼此相对时,可以使用公共的墨水供应歧管来将墨水供应到全宽度交错阵列中的所有打印头子单元,从而消除了对两个单独的墨水供应歧管的需要。 通过改变通常用于形成打印头子单元的通道板的结构,可以完全消除对单独的供墨歧管的需要。

The semiconductive device, formed by the linear abutment of semiconductive sub-units divided from a larger semiconductive wafer must be accurately positioned to enable the operation of which it was intended. In one embodiment, the sub-units are thermal ink jet arrays which are abutted to form a pagewidth printhead. The semiconductive device includes a reference plate or substrate having a generally planar surface for mounting an array of functional sub-units thereon. The semiconductive device further includes two or more individual sub-units which are also affixed to the planar surface, thereby forming alignment pads for the assembled semiconductive device. When incorporated into the system, the alignment pads are received by frame members or alignment points to provide positive alignment of the reference plate, and the attached array of sub-units, within the system.

    • The new heater element design has a pit layer which protects the overglaze passivation layer, PSG step region, portions of the Ta layer and dielectric isolation layer and junctions or regions susceptible to the cavitational pressures. Further, the inner walls of the pit layer define the effective heater area and the dopant lines define the actual heater area. In alternative embodiments, the dopant lines define the actual and effective heater areas, and an inner wall and a dopant line define the actual and effective heater areas. Further, when the new heater element designs are incorporated into printheads having 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 incorporating the new heater element design can be incorporated into drop-on-demand printing systems of a carriage type or a full width type.

    • A method and apparatus for drying liquid ink deposited, in response to image data, on a recording medium moving along a path at a predetermined rate. A recording medium having liquid ink deposited thereon is moved past a dryer in multiple passes to dry areas of high ink coverage. Ink characteristics are optimized for minimum print defects by determining the time between printing and drying. In the case of text only images only one pass through the dryer is required. For areas of high ink coverage, however, multiple passes through the dryer are required and completed either by reciprocation or recirculation at the same predetermined rate.
