    摘要： An inkjet printer that has an ink supply, an ink manifold in fluid communication with the ink supply, a printhead IC with and array of ink ejection nozzles mounted to the ink manifold, a pump in fluid communication with the ink manifold and, a gas inlet that can be opened to establish fluid communication between the ink manifold and a supply of gas, and can be closed to form a gas tight seal. The ink manifold can be primed using the pump by closing the gas inlet, and de-primed when the gas inlet is open. This allows the printhead to be deprimed during storage and transport and it allows the printhead IC to be cleaned by a foam formed by air forced through the ink election nozzles.

    摘要翻译： 一种具有墨水供应的喷墨打印机，与墨水源流体连通的墨水歧管，具有安装到墨水歧管上的喷墨嘴阵列的喷墨头IC，与墨水歧管流体连通的泵，以及气体入口 可以打开以在油墨歧管和气体供应之间建立流体连通，并且可以关闭以形成气密密封。 油墨歧管可以通过关闭气体入口使用泵引燃，当气体入口打开时，油墨歧管可以被排除。 这样可以在存储和运输期间使打印头脱落，并且允许打印头IC被被强制通过墨水选择喷嘴的空气形成的泡沫清洁。

    摘要： A printhead maintenance system for maintaining a printhead having an ink ejection face is provided. The maintenance system comprises: (a) a foaming system for providing liquid foam on the face, (b) a foam transfer surface for receiving the foam from said face, (c) a transport mechanism for feeding said transfer surface through a transfer zone and away from said printhead, and (d) a valve configurable in first and second positions, the first position for establishing fluid communication between said printhead and an ink supply system and the second position for establishing fluid communication between said printhead and said foaming system. The transfer zone is adjacent to and spaced apart from said ink ejection face.
