20100061762 | NON-REMOVABLE CRU LIGHT SHIELD REPLACEMENT FOR PULL STRIP - This is a shroud for housing a replacement photoconductive drum. The shroud has an open gap at its top portion and this gap is covered by at least two overlapping flexible strips that are configured to allow a handle structure to pass therethrough on its way to an exit in the shroud where the photoconductive drum is pushed out of the shroud when installing the drum in a marking machine. | 03-11-2010 |
20110052252 | BIAS CHARGING OVERCOAT - There is described a bias charging member that includes a conductive core and an outer surface layer on the conductive core. The outer surface layer includes a resin of aminoplast and one of polyol or nylon, a conductive additive and p-toluene sulfonic acid. There is also described a method of refurbishing bias charging members. | 03-03-2011 |
20110123219 | BIAS CHARGING OVERCOAT - Provide herein is a description of a bias charging member that includes a conductive core, and an outer surface layer disposed on the conductive core. The outer surface layer includes carbon black and acrylonitrile-butadiene-styrene. | 05-26-2011 |
