    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： A method of maintaining an ink ejection face of an inkjet printhead. The method comprises the steps of: (i) flooding the ink ejection face with ink from nozzles in the printhead; and (ii) rotating a roller adjacent the face, such that flooded ink is transferred from the face onto an outer surface of the roller. The outer surface of the roller does not contact the face during rotation of the roller.
