Abstract
A document feeder device is disclosed. The document feeder device includes a frame, a first roller shaft coupled to the frame, and a second roller shaft coupled to the frame. The first shaft is cantilevered. The document feeder device further includes a bearing coupled to the first roller shaft. The bearing has an eccentric shape and the eccentric shape allows the bearing to be rotated such that the position of the first roller shaft stays parallel to a second roller shaft. As a result, rollers attached to the first and second roller shafts are kept aligned so that they reliably feed documents through a printer. The document feeder device decreases production costs by eliminating the need for additional frame hardware and/or more rigid frame hardware.
