Dust control in conductive-core fiber brush cleaning systems using self-generated air flow

摘要

A method and apparatus of forming a cleaning system for an electrostatographic reproduction system having a photoconductive drum partially within a cleaning system housing and a cleaning brush having conductive core fibers within the cleaning system housing contacting the photoconductive drum with a detoner roller also within the cleaning system housing contacting the cleaning brush. The cleaning system housing is provided with ports that allow for air in enter of leave the cleaning system housing. A curved deflector plate is positioned such that it is spaced about ⅛'' from the cleaning brush. The deflector plate is attached to the enclosure on a side where the brush fibers are moving towards the detoner roller. A skive is made to contact the detoner roller, a baffle is formed contacting the skive and a side of the cleaning housing. The cleaning system is preferably designed such that the ratio of engagements of the detoner roller to the cleaning brush compared to that of the toner bearing surface to the cleaning brush, is essentially three to one.
