  • Patent number: 8301057
    Abstract: A printer cartridge is provided that allows a charge roller to be separated from a photoconductive drum when the printer cartridge is not used within an image forming device. The printer cartridge includes the photoconductive drum, the charge roller, and a separating member having a resilient member disposed thereon with the separating member being disposed on the charge roller. The separating member engages and disengages the photoconductive drum in a first position and in a second position. The first position provides a spaced relationship between the charge roller and the photoconductive drum and the second position provides an engaged relationship between the charge roller and the photoconductive drum. The printer cartridge also includes the photoconductive drum disposed adjacent to the charge roller in an offset orientation that includes a centerline of a charge roller shaft offset by a predetermined distance from a centerline of a photoconductive drum shaft.

  • Patent number: 7734226
    Abstract: The present application is directed to devices and methods to position a developer member relative to a photoconductive member in an image forming device. One embodiment includes an elongated lift plate positioned in proximity to a photoconductive member. An elongated opening may be positioned within the lift plate. The opening may include a first section and a second section. The first section may be positioned farther from the photoconductive member than the second section. A positioning member may be positioned within the opening, and be operatively connected to the developer member. A hold down may bias the positioning member towards an edge of the opening. The lift plate may be longitudinally movable between a first position with the positioning member in the first section of the opening that positions the developer member away from the photoconductive member, and a second position with the positioning member in the second section that positions the developer member against the photoconductive member.
