摘要： A printhead assembly with a printhead integrated circuit (IC) and a shut off (138) valve that has a valve body (200) defining an ink inlet (202) for connection to an ink supply, an ink outlet (67) connected to the printhead IC. A moveable valve member (212) is biased into sealing engagement with the valve seat (216) to provide a fluid seal between the ink inlet and the ink outlet. An actuator (204) for unsealing the valve member from the valve seat upon energizing and re-sealing the valve member to the valve seat when de-energized. The valve protects the ink in the ink supply from contaminants that can migrate up the ink line during shut down periods. The valve member is constantly biased to a closed position and so seals the ink supply from the printhead IC as a default condition even in the event of a power failure. The bias is strong enough to provide the fluid seal so that the seal is not compromised when the pressure difference between the inlet and the outlet is small.
摘要翻译：一种具有打印头集成电路（IC）和关闭（138）阀的打印头组件，其具有限定用于连接到墨水供应源的墨水入口（202）的阀体（200），连接到墨水出口打印头IC。可移动的阀构件（212）被偏置成与阀座（216）密封接合，以在墨水入口和墨水出口之间提供流体密封。一个致动器（204），用于当断电时对阀构件进行通电并将阀构件重新密封到阀座上，从而将阀构件从阀座开启。阀门保护墨水供应中的墨水免受在关闭期间可能向上移动墨水管线的污染物。阀构件经常被偏置到关闭位置，并且即使在电源故障的情况下也将打印头IC的墨水供应密封为默认状态。该偏压足够强以提供流体密封，使得当入口和出口之间的压力差小时，密封件不会受到影响。

摘要： A method of feeding porous sheets of media from a stack of such sheets includes the step of applying a gas flow to a first sheet of a stack, via a gas conduit and nozzle so that the gas passes partially through the first sheet and impinges on a second sheet, generating a cushion of air between the first and second sheets to separate the first and second sheets. The gas flow is reversed so that the first sheet is drawn towards a pick-up surface and retained against the pick-up surface. A pick-up device that defines the pick-up surface is displaced along the feed path so that the first sheet is fed from the stack along the feed path.
