摘要： A multi-chamber inkjet print head includes a plurality of individual print head ink chambers that share a common ink filter and are in fluid communication with an ink flow regulator. An associated method of assembling a print head base having at least two separate fluid conduit paths filtered by a single piece of filter includes the steps of: (a) positioning a single piece filter between at least two separate ink receptacles associated with a print head and at least two respective ink conduits; and (b) sealing at least two separate ink paths between the at least two separate ink receptacles associated with the print head and the at least two ink conduits, such that the single piece of filter is in concurrent fluid communication with the at least two separate ink paths.

摘要： Methods for disassembling at least two components of an inkjet printhead include applying heat, preferably in the form of laser energy, to one of the components and wholly or partially separating the components thereafter. The disassembly enables ease of refilling the inkjet printhead or replacing original parts. In one embodiment, the components comprise inkjet printhead lids and bodies originally laser welded to one another. In another aspect, methods of disassembly include laser unwelding inkjet printhead lids and bodies according to whether the inkjet printhead body embodies a mono or color ink body type through use of selective control of one or more laser light sources to illuminate the inkjet printhead lid in a specific pattern of light. Still other aspects include a disassembled inkjet printhead having components with laser welding residue thereon. The laser welding residue may have substantially matching edge lines between the two components.
摘要翻译：用于拆卸喷墨打印头的至少两个部件的方法包括将优选以激光能量的形式的热量施加到其中一个部件，然后将部件全部或部分分离。拆卸使得易于重新填充喷墨打印头或更换原始部件。在一个实施例中，组件包括原始地彼此激光焊接的喷墨打印头盖和主体。在另一方面，拆卸方法包括根据喷墨打印头体是否通过选择性地控制一个或多个激光源以喷墨打印头盖来照亮喷墨打印头盖来体现单色或彩色墨体型的激光焊接喷墨打印头盖和主体具体的光线模式。还有其它方面包括具有在其上具有激光焊接残留的部件的分解的喷墨打印头。激光焊接残余物可以在两个部件之间具有基本匹配的边缘线。

摘要： A multi-chamber inkjet print head includes a plurality of individual print head ink chambers (120, 122, 124) that share a common ink filter and are in fluid communication with an ink flow regulator (10”). An associated method of assembling a print head base having at least two separate fluid conduit paths filtered by a single piece of filter (128, 128’) includes the steps of: (a) positioning a single piece filter between at least two separate ink receptacles associated with a print head and at least two respective ink conduits; and (b) sealing at least two separate ink paths between the at least two separate ink receptacles associated with the print head and the at least two ink conduits, such that the single piece of filter (128, 128’) is in concurrent fluid communication with the at least two separate ink paths.
