  • Devices and Methods for Retracting a Cartridge in an Image Forming Device
    Publication number: 20120294650
    Abstract: The present application is directed to methods and devices for moving a cartridge between engaged and disengaged positions in an image forming device. The image forming device may include a bias control arm movable between first and second positions. When the bias control arm is in one of the first and second positions, a biasing force on the cartridge is reduced and the cartridge moves to the disengaged position. When the bias control arm is in the other of the first and second positions, a biasing force on the cartridge is increased and the cartridge is moved to the engaged position. In one embodiment, the bias control arm moves in a first direction, and the cartridge moves in a second direction different than the first direction.
