A drum cover or protector includes features that allow it to be used with substantially any xerographic device cartridge designed to be used in a xerographic device adapted to handle standard paper sizes. The drum protector may be secured to the cartridge in a protecting position. In this position, the protector covers the drum and blocks objects from coming into contact with the drum surface. The drum protector also includes an arrangement that prevents any critical part of the drum surface from coming into contact with the cover itself.

Universal drum cover for xerographic device cartridges

A toner cartridge (10) includes a bin component (11) and a cover component (12) adapted to be connected together in a connected position. The bin component (11) includes a toner bin (14) having a bin opening (15) and further includes a toner bin sealing surface (20) extending around the periphery of the bin opening (15). The cover component (12) includes a cover opening (26) and a cover sealing surface (30). When the bin component (11) and cover component (12) are in the connected position the toner bin sealing surface (20) is aligned with the cover sealing surface (30) so that the surfaces defining a seal receiving pocket. The seal receiving pocket is adapted to receive a toner bin seal (60) which includes a base sheet (61) comprised of a resilient material having a thickness greater than the clearance between the toner bin sealing surface (20) and cover sealing surface (30). The toner bin seal (60) includes a removable sealing film (68) which may be removed to expose the toner contained in the toner bin (14).
