Abstract
A wiping assembly for a fluid ejection device includes a sled slidably movable relative to the fluid ejection device. The wiping assembly further includes a length of wiping material. An indicator slidably coupled to the wiping assembly is included. The indicator changes position relative to the wiping assembly and restricts movement of the wiping assembly to an initial position to indicate a level of usage of the wiping material.
