    • A maintenance system for maintaining a stationary printhead is disclosed. The maintenance system includes a porous wiper element movable longitudinally past the printhead. The wiper element contacts the printhead during movement in at least one direction of longitudinal movement. A pump is included for pumping liquid into the wiper element. A rotating means is included for spinning the wiper element to thereby spin liquid and contaminants from the wiper element. By spinning the wiper element the wetness thereof is reset to a known condition. Advantageously the wetness of the wiper element is then set to a desired level by controlling the amount of liquid pumped by the pump into the wiper element. In order to clean the wiper element, the wiper element is saturated with liquid before spinning the wiper element again, followed by another spinning operation. Other levels of wetness include a level for rehydrating the printhead, and another level for wiping the printhead.
    • 公开了维护固定打印头的维护系统。 维护系统包括可沿着打印头纵向移动的多孔擦拭器元件。 擦拭器元件在纵向运动的至少一个方向的运动期间接触打印头。 包括用于将液体泵入刮水器元件的泵。 包括旋转装置以旋转擦拭器元件,从而从擦拭器元件旋转液体和污染物。 通过旋转刮水器元件,其湿度被重新设定为已知状态。 有利的是,通过控制泵抽入刮水器元件的液体量,将刮水器元件的湿度设定到所需的水平。 为了清洁刮水器元件,在再次旋转刮水器元件之前,擦拭器元件被液体饱和,接着进行另一个旋转操作。 其他湿度水平包括用于再水化打印头的水平,以及擦拭打印头的另一个水平。
