Abstract
Fuser apparatus for fixing toner images to substrates comprising a heated fuser roll structure and a backup roll structure forming a nip through which the substrates pass with the toner images contacting the heated fuser roll structure to thereby soften the toner images. A cleaning structure for removing toner offset to said fuser roll structure comprises a plurality of flexible fingers supported for wiping contact with the fuser roll structure. Spaces between the finger serve as areas for collecting the toner to prevent the toner from re-applied to the fuser roll. The cleaning structure contacts areas of the fuser roll prior to such areas being contacted by a wick employed for applying offset preventing liquid to the fuser roll, such positioning of the fuser roll structure serving to prolong the life of the wick.
