Abstract
Abstract A blade cleaning station is provided for an electrostatographic reproducing apparatus comprising an endless, flexible belt having an imaging surface thereon supported for movement between two support members defining a substantially horizontal top run therebetween. The cleaning station comprises a rigid stationary cleaning platen under the top run of the belt between the support members and a cleaning blade mounted in opposed relationship thereto on the imaging surface of the belt in interference with the imaging surface on said belt such that its beam deflection provides the force required to clean the imaging surface and the toner cleaned from the imaging surface lubricates the nip between the cleaning blade and the imaging surface.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
In an electrostatographic reproducing apparatus comprising an endless flexible belt having an imaging surface thereon supported for movement between two support members defining a substantially horizontal top run therebetween, a blade cleaning station for removing residual toner particles from the imaging surface comprising a rigid stationary cleaning platen under the top run of said belt between said support members for supporting said belt thereon and a cleaning blade mounted in opposed relationship to said cleaning platen on the imaging surface of said belt for removing residual toner therefrom, said cleaning blade being positioned in interference with said imaging surface on said belt supported by said cleaning platen such that its beam deflection provides the force required to clean the imaging surface and toner cleaned from said imaging surface lubricates the nip between the cleaning blade and the imaging surface.
Claim 2
Dependent Claim
139 words
In an electrostatographic reproducing apparatus comprising an endless flexible belt having an imaging surface thereon supported for movement between two support members defining a substantially horizontal top run therebetween, a blade cleaning station for removing residual toner particles from the imaging surface comprising a rigid stationary cleaning platen under the top run of said belt between said support members for supporting said belt thereon and a cleaning blade mounted in opposed relationship to said cleaning platen on the imaging surface of said belt for removing residual toner therefrom, said cleaning blade being positioned in interference with said imaging surface on said belt supported by said cleaning platen such that its beam deflection provides the force required to clean the imaging surface and toner cleaned from said imaging surface lubricates the nip between the cleaning blade and the imaging surface.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1, wherein said cleaning blade is rigidly mounted within a cleaner sump housing on top of the top run of said flexible belt.
Claim 4
Dependent Claim
25 words
The apparatus of claim 2, wherein a flexible flap seal is mounted to said sump housing upstream of said cleaning blade in the process direction.
Claim 5
Dependent Claim
22 words
The apparatus of claim 1, wherein the top of said cleaning blade is positioned directly opposite a portion of said cleaning platen.
Claim 6
Dependent Claim
32 words
The apparatus of claim 1, wherein the top of said cleaning blade is positioned from 2 to 5 mm upstream in the process direction of the leading edge of the cleaning platen.
Claim 7
Dependent Claim
13 words
The apparatus of claim 1, wherein said cleaning blade is an elastomeric material.
Claim 8
Dependent Claim
21 words
The apparatus of claim 1, wherein said cleaning blade is in wiping contact with said imaging surface for removing toner therefrom.
Claim 9
Dependent Claim
21 words
The apparatus of claim 1, wherein said cleaning blade is in chiselling contact with said imaging surface for removing toner therefrom.
Claim 10
Dependent Claim
25 words
The apparatus of claim 1, wherein said supported endless flexible belt and said blade cleaning station comprise a removable processing cartridge for said reproducing apparatus.
