    Abstract: A silencer assembly that has an extended life, is recycleable and suitable for reducing screeching noises between a cleaning blade and an imaging member of an electrostatographic reproduction machine. The silencer assembly includes (i) a first C-shaped member having a wall defining a slot extending axially in the wall, and an interior cavity having a predetermined inside diameter in the free state, (ii) at least one partially compressed high density polymeric open cell foam plug inserted into the interior cavity, and (iii) a replaceable second C-shaped member inserted within the interior cavity for reducing plastic deformation of the first C-shaped member, thereby extending life of the silencer and making the silencer easily recyclable by replacing the second C-shaped member.
