The engagement portions are configured to receive driving rotatable force from the drive mechanism of a printer.

Abstract: A method is disclosed. The method provides an assembly that contains a first drum-cylinder having an inner periphery surface and a drive gear assembly, wherein a portion of the drive gear assembly is in contact with the inner periphery surface, separates the drive gear assembly from the first drum-cylinder, inserts the portion of the drive gear assembly into a second drum-cylinder, and couples the drive gear assembly to the second drum-cylinder.

Abstract: A gasket seal is disclosed. The gasket seal containing a gasket defining an opening containing a first gasket longitudinal edge, a second gasket longitudinal edge, a gasket transverse edge, wherein the gasket transverse edge forms a 90 degree angle with the first gasket longitudinal edge and the second gasket longitudinal edge, a seal strip containing a first seal longitudinal edge, a second seal longitudinal edge, and a seal transverse edge, wherein the seal transverse edge forms an acute angle with the first seal longitudinal edge wherein the seal transverse edge forms an obtuse angle with the second seal longitudinal edge, wherein the seal strip is removably coupled with the gasket.

Abstract: A remanufactured toner cartridge includes a wall defining a fill hole that is used to refill the cartridge with toner. A patch covers the fill hole, and a heat activated adhesive non-removably attaches the patch to the wall. The fill hole can be formed with a heat knife such that when the heat knife is withdrawn it forms a raised ridge of material extending around the perimeter of the fill hole. The patch is attached to the wall by applying heat and pressure to the patch, which also softens and at least partially flattens the ridge of material surrounding the fill hole such that the patch is substantially flush with the wall upon completion of the operation.

Abstract: A device is disclosed. The device contains a roller, a housing configured to accommodate the roller, at least one seal comprising a first material, wherein the at least one seal is disposed between the roller and the housing, and at least one second material disposed adjacent to the seal.

Abstract: A refurbished toner blade for a toner cartridge and a method for refurbishing a toner blade for a toner cartridge are provided. The refurbished toner blade includes a fixed portion configured for attachment to a portion of a toner cartridge, a depending portion extending away from the fixed portion, and a permanent deflection that is formed during refurbishment of the toner blade and that extends between the fixed portion and the depending portion. The refurbished toner blade is formed from a used toner blade in which the depending portion has obtained a permanent deformation in a first direction after an initial period of use. The permanent deflection deflects the depending portion in a second direction opposite the first direction.

Abstract: A remanufactured laser printer toner cartridge, and methods, having an added primary charge roller cleaning roller assembly. In an exemplary embodiment, the cleaning roller assembly engages the bare ends the primary charge roller shafts; installation of the cleaning roller assembly into the cartridge is accomplished by reinstalling the primary charge roller, with the assembly, into the cartridge's primary charge roller shaft saddles. The cleaning roller may be adapted to rotate through contact with the primary charge roller.

Abstract: Methods of recoating a developing member such as the doctor blade, developing member bar or a developing sleeve, of an electro-photographic image forming apparatus, such as a laser printer toner cartridge, methods of re-using the original components by re-coating them, to cut the cost of using new aftermarket parts and to reduce waste, which methods include close quality control and “tailoring” of formulations to a specific developing system, thus achieving better print quality in terms of density, page yield, and uniformity for the repaired or remanufactured toner cartridge.

Abstract: Remanufactured laser printer toner cartridges and methods of manufacture by which predetermined structures internal to the toner hopper section are removed preferably by a robotic laser cutter, a volume increasing cap is provided for the modified toner hopper section and the cartridge is re-assembled to yield a remanufactured toner cartridge that has a capacity to store toner that is significantly increased in comparison to the storage capacity of the OEM toner cartridge.

Abstract: A drivable projection for a toner cartridge drum gear includes an axially extending support portion having a plurality of axially extending edges and an end face. A plurality of substantially spherical engagement portions are supported by the support portion, and each engagement portion defines a center that may be substantially aligned with the end face and/or substantially aligned with a respective one of the plurality of axially extending edges.
