  • Retrofit cleaning roller assembly
    Patent number: 6775508
    Abstract: A roller cleaning apparatus for retrofit installation in a photocopier fuser assembly having a housing and a fuser roller mounted in the housing. The apparatus may comprise a mounting strip adapted to engage a surface within the housing, a pair of resilient brackets spaced apart on the mounting strip, and a cleaning roller. Each of the resilient brackets has a bearing portion, and the cleaning roller is disposed between the pair of resilient brackets. The cleaning roller has a pair of opposing ends, each rotationally mounted in one of the bearing portions. The resilient brackets are configured so as to bias the cleaning roller against the fuser roller when the mounting strip is engaged with the housing. Also, a method for installing a roller cleaning apparatus in a photocopier fuser assembly.
