Patent ID: 7798599

Claim:
A service station for a fluid-ejection mechanism of a fluid-ejection device, comprising: a plurality of mechanisms to move back and forth over the fluid-ejection mechanism to wipe the fluid-ejection mechanism, and to cap the fluid-ejection mechanism during periods of nonuse of the fluid-ejection mechanism, the mechanisms comprising: a wiping mechanism to move back and forth over the fluid-ejection mechanism to wipe the fluid-ejection mechanism; a capping mechanism to cap the fluid-ejection mechanism during periods of nonuse of the fluid-ejection mechanism; and, a housing mountable on the fluid-ejection mechanism and defining an opening within which the wiping mechanism is movably disposed, such that the wiping mechanism moves back and forth within the opening of the housing to wipe the fluid-ejection mechanism, wherein the service station is mounted on the fluid-ejection mechanism, and remains mounted on the fluid-ejection mechanism while the fluid-ejection mechanism is used to eject fluid, wherein the fluid-ejection mechanism is moved by a user to properly eject the fluid, and wherein the wiping mechanism defines a slot, such that in a first position of the wiping mechanism a plurality of fluid-ejection nozzles of the fluid-ejection mechanism are exposed through the slot, and in a second position of the wiping mechanism the fluid-ejection nozzles are capped by the capping mechanism.
