  • Rotary wiper assembly for fluid-ejection printhead
    Publication number: 20100225699
    Abstract: A rotary wiper assembly for a fluid-ejection printhead that has fluid-ejection nozzles includes one or more wipers and a rotatable shaft to which the wipers are at least indirectly attached. The rotatable shaft is to rotate the wipers to a static wiping position. While the wipers are stationary in the static wiping position, the fluid-ejection printhead is to move back and forth in relation to the wipers while the wipers are not to move, to cause the wipers to come into contact with the fluid-ejection nozzles to wipe material from the fluid-ejection nozzles.
