摘要： Several methods are provided for cleaning felt or foam materials that are used to store and deliver ink, particularly ink supplied to ink jet printheads in an ink jet printing system. The felt materials are contaminated during manufacture, by various antistats, primarily phosphates. These antistats later react with the ink to create kogation and nozzle blocking problems as well as reduction of surface tension of the ink. The methods of the invention are directed to reducing the antistats left in the storage material after manufacture. In one method, the material is washed in heated softened water. Prior to loading the material in the wash, IPA is added to the heated wash. The material is washed through two Wash/Rinse cycles and then dried. The removal of the calcium in the wash water via softening prevents the precipitation of calcium-phosphate salts, which, when the material later contacts the ink, reduces nozzle clogging caused by these precipitates. The addition of the IPA increases removal of the phosphate antistats and greatly reduces the kogation and clogging problems. In a second embodiment, the storage material is washed in tap water to which has been added the IPA as well as a chelating agent. The chelating agent prevents the calcium from forming a precipitate with the remaining antistats in the material and provides the same function against any calcium or other divalent metal ions that may be introduced during ink flow from material to printhead nozzle.
摘要翻译：提供了几种用于清洁用于存储和输送墨水的毛毡或泡沫材料的方法，特别是在喷墨打印系统中供应给喷墨打印头的墨水。毛毡材料在制造过程中受到各种抗静电剂，主要是磷酸盐的污染。这些抗静电剂随后与油墨发生反应，产生卡格和喷嘴堵塞问题以及降低油墨的表面张力。本发明的方法涉及减少制造后留在储存材料中的抗静电剂。在一种方法中，将材料在加热的软化水中洗涤。在将材料装入洗涤液之前，将IPA加入到加热的洗涤液中。通过两次洗涤/漂洗循环洗涤材料，然后干燥。通过软化去除洗涤水中的钙可防止磷酸钙盐的沉淀，当磷酸盐材料稍后与油墨接触时，会减少由这些沉淀引起的喷嘴堵塞。 IPA的添加增加了磷酸盐抗静电剂的去除，并大大减少了烧结和堵塞问题。在第二个实施方案中，储存材料在添加了IPA的自来水以及螯合剂中洗涤。螯合剂防止钙与材料中剩余的抗静电剂形成沉淀物，并且对于在从材料到打印头喷嘴的油墨流动期间可能引入的任何钙或其它二价金属离子提供相同的功能。

摘要： In one embodiment of an ink jet print cartridge wherein ink flows from an ink container to a printhead via an ink manifold which includes an ink pipe which projects into an outlet port in the ink container. The interface between the manifold and the outlet port is sealed by placing a foam member, in compression, between two adjoining surfaces. In one embodiment, the foam is a closed cell neoprene. In another embodiment, the foam is a dual membrane consisting of a first layer of closed cell foam laminated to an open cell foam. In a third embodiment, a member is used to both seal the pipe to outlet port interface and also to wipe the ink pipe clear of ink. A polyurethane member is affixed to the outside surface of the ink container adjacent the outlet port. The polyurethane member has an aperture with a diameter which is smaller than the outside diameter of the ink pipe. When the ink pipe is projected through the polyurethane member aperture, it causes the member to extend over the top surface of the ink pipe and into a sealing engagement thereon. Upon withdrawal of the pipe (or withdrawal of the container), the polyurethane acts as a wiper to wipe the surface of the ink pipe free of any residual ink.
摘要翻译：在喷墨打印墨盒的一个实施例中，墨水通过墨水歧管从墨水容器流动到打印头，墨水歧管包括突出到墨水容器中的出口的墨水管。歧管和出口之间的接口通过将泡沫构件压缩在两个相邻的表面之间进行密封。在一个实施方案中，泡沫是闭孔氯丁橡胶。在另一个实施方案中，泡沫是由层压到开孔泡沫的第一层闭孔泡沫构成的双膜。在第三实施例中，使用构件将管道密封到出口端口并且还将墨水管清除墨水。聚氨脂部件固定在墨水容器的与出口相邻的外表面。聚氨酯部件具有直径小于墨水管的外径的孔。当墨水管通过聚氨酯构件孔突出时，其使构件在墨水管的顶表面上延伸并在其上形成密封接合。在抽出管道（或容器撤回）时，聚氨酯用作擦拭器以擦拭墨水管的表面而没有任何残留的墨水。
