An apparatus for maintaining a printhead is provided having a rotatable wiper roller having a shaft and a porous material about the shaft, a rotatable transfer roller in rotatable contact with the wiper roller, and a mechanism for rotating the wiper roller so that the porous material rotates against the printhead such that the porous material absorbs fluid from the printhead during the rotation, and for rotating the transfer roller against the wiper roller so that the fluid absorbed by the porous material is transferred to the transfer roller.
