Abstract
A low profile, alignment assembly for a media feed roll assembly using torsion spring biasing. The alignment assembly has a first and a second spaced bushings mountable to a frame. Each bushing has a circular collar and a cradle positioned along a common centerline for rotatably holding a driven first and an opposed second shaft on the common centerline. A first and a second torsion spring mount around the second shaft adjacent to the first and second bushing, respectively, and each has a pair of legs extending tangentially therefrom, attachable to the frame or respective bushing and forming a substantially planar profile. Each torsion spring biases the second shaft toward the first shaft along the common centerline and, as a media sheet moves between the first and second shafts, allows the second shaft to move within the cradles radially away from the first shaft along the common centerline.
