    • A clean-in-place system for use in an ink jet printhead has a compartment and an end plate with a slot therein to permit ink drops to be projected from the compartment onto a substrate to be marked. For cleaning purposes, a shutter is disposed adjacent the slot to seal it. Thereafter, the pump floods the compartment with ink solvent from a solvent reservoir. The solvent may be agitated by air or a mechanical device. Thereafter, a drain line is used to remove the solvent from the compartment. The pneumatic shutter is reopened after the solvent is withdrawn to enhance the drying of the components. The shutter may consist of an inflatable member and a pump for supplying compressed air to the inflatable member to inflate and deflate it.
    • 用于喷墨打印头的清洁就位系统具有隔室和在其中具有狭槽的端板,以允许墨滴从隔室突出到待标记的基板上。 为了清洁目的,快门被设置在狭槽附近以将其密封。 此后,泵用溶剂储存器中的油墨溶剂使隔室溢出。 溶剂可以通过空气或机械装置搅拌。 此后,使用排水管线从隔室中除去溶剂。 在抽出溶剂后,再次打开气门,以增强部件的干燥。 快门可以由可膨胀构件和用于将压缩空气供应到可膨胀构件以使其膨胀和放气的泵构成。

    • A system for printing with ink droplets each having a known quantity of ink which system has a hydraulic portion including a main ink supply, a supplemental ink supply and a recirculating droplet generating print head and an electronic portion which includes a character generator for electrically characterizing each of the droplets so that they are directed either to a print target or to a dump and a monitoring means for identifying the droplets assigned to strike the print target and controls in the hydraulic portion for permitting a metered additional quantity of ink, depending on the number of print target directed droplets counted, to flow from the supplemental ink supply to the main ink supply, thus, allowing use of a standard ink formulation in the supplemental ink supply.

    • According to certain aspects of an embodiment of the present invention, a deflection electrode assembly is provided for use in a continuous ink jet printer of the type which projects a stream of ink drops toward a substrate and controls placement of the ink drops on the substrate by selectively charging the individual ink drops and passing the charged ink drops through an electric (deflection) field created by the deflection electrode assembly. The deflection electrode assembly includes a high voltage deflection electrode and a low voltage deflection electrode positioned on opposite sides of the ink drop stream. A dielectric insulating member is mounted on at least one of the deflection electrodes. The insulating member include a longitudinal opening which exposes the deflection electrode along the path of the ink jet stream, thereby virtually eliminating the tendency for accumulated ink to decrease the strength of the deflection field. The insulating member extends inwardly and underlies the bottom face of the deflection electrode along at least its front and side edges. Providing insulation along the front and side edges of the deflection electrode reduces arcing between the deflection electrodes. Providing the longitudinal opening in the insulating member reduces the field distortion effects of micro-satellite ink drops that would otherwise accumulate on the insulating member.
    • 根据本发明的实施例的某些方面,提供了一种用于连续喷墨打印机的连续喷墨打印机,该打印机将墨滴流朝向基底投影,并通过以下方式控制墨滴在基片上的放置: 选择性地对各个墨滴进行充电,并使带电的墨滴通过由偏转电极组件产生的电(偏转)场。 偏转电极组件包括位于墨滴流的相对侧上的高电压偏转电极和低电压偏转电极。 电介质绝缘构件安装在至少一个偏转电极上。 绝缘构件包括沿着喷墨流的路径使偏转电极露出的纵向开口,从而实际上消除了累积墨水降低偏转场强度的倾向。 绝缘构件沿着至少其前侧和侧边缘向内延伸并且在偏转电极的底面下方延伸。 沿着偏转电极的前边缘和侧边缘提供绝缘,减少了偏转电极之间的电弧。 在绝缘构件中提供纵向开口减小了否则会积聚在绝缘构件上的微卫星墨滴的场失真效应。
