Abstract
Abstract An apparatus for cleaning particles from the imaging surface and the ground strip located along the edge of the imaging surface. The conductive cleaning brush will short with the ground strip causing copy quality defects. An insulative brush donut is attached to the conductive cleaning brush for cleaning. The insulative brush donut will not short with the ground strip and the insulative brush prevents contact between the conductive fibers and the ground strip.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
72 words
An apparatus for cleaning particles from a surface having an electrical ground strip along a marginal region of the surface, comprising: a housing defining an open ended chamber; a brush, rotatably mounted in the chamber of said housing, for removing particles from the surface; and means, attachable to said brush, for cleaning particles from the ground strip of the surface, said cleaning means being insulative to prevent shorting with the ground strip.
Claim 2
Independent Claim
72 words
An apparatus for cleaning particles from a surface having an electrical ground strip along a marginal region of the surface, comprising: a housing defining an open ended chamber; a brush, rotatably mounted in the chamber of said housing, for removing particles from the surface; and means, attachable to said brush, for cleaning particles from the ground strip of the surface, said cleaning means being insulative to prevent shorting with the ground strip.
Claim 3
Dependent Claim
24 words
An apparatus as recited in claim 1, wherein said brush comprises: a core; and a plurality of fibers extending radially outwardly from said core.
Claim 4
Dependent Claim
13 words
An apparatus as recited in claim 2, wherein said fibers are electrically conductive.
Claim 5
Dependent Claim
62 words
An apparatus as recited in claim 3, wherein said core of said brush comprises: a first end; and a second end opposed from said first end, with said first end including a first end cap thereon and said second end including a second end cap, said first end cap and said second end cap allowing said cleaning means to attach easily thereto.
Claim 6
Dependent Claim
16 words
An apparatus as recited in claim 3, wherein said cleaning means comprises a donut shaped brush.
Claim 7
Dependent Claim
18 words
An apparatus as recited in claim 5, wherein said donut shaped brush rotates in unison with said brush.
Claim 8
Independent Claim
171 words
An apparatus for cleaning particles from a surface having an electrical ground strip along a marginal region of the surface, comprising: a housing defining an open ended chamber; a brush, rotatably mounted in the chamber of said housing, for removing particles from the surface, said brush comprising a core and a plurality of electrically conductive fibers extending radially outwardly from said core, said core comprising a first end, and a second end opposed from said first end, with said first end including a first end cap thereon and said second end including a second end cap, said first end cap and said second end cap allowing said cleaning means to attach easily thereto; and means, easily attachable to said brush, for cleaning particles from the ground strip of the surface, said cleaning means comprises a donut shaped brush, said donut shaped brush comprises a hub, defining an aperture therein, and a plurality of fibers extending radially outwardly from said hub in frictional contact with the ground strip for removing particles therefrom.
Claim 9
Independent Claim
171 words
An apparatus for cleaning particles from a surface having an electrical ground strip along a marginal region of the surface, comprising: a housing defining an open ended chamber; a brush, rotatably mounted in the chamber of said housing, for removing particles from the surface, said brush comprising a core and a plurality of electrically conductive fibers extending radially outwardly from said core, said core comprising a first end, and a second end opposed from said first end, with said first end including a first end cap thereon and said second end including a second end cap, said first end cap and said second end cap allowing said cleaning means to attach easily thereto; and means, easily attachable to said brush, for cleaning particles from the ground strip of the surface, said cleaning means comprises a donut shaped brush, said donut shaped brush comprises a hub, defining an aperture therein, and a plurality of fibers extending radially outwardly from said hub in frictional contact with the ground strip for removing particles therefrom.
Claim 10
Dependent Claim
31 words
An apparatus as recited in claim 7, wherein said first end cap snaps into the aperture in said hub, securely attaching said donut shaped brush adjacent one end of said brush.
Claim 11
Dependent Claim
17 words
An apparatus as recited in claim 7, wherein said fibers of said brush donut are electrically nonconductive.
Claim 12
Dependent Claim
13 words
An apparatus as recited in claim 7, wherein said hub is electrically nonconductive.
