Abstract: A magnetic paper-feeding roller assembly is adapted to feed a piece of paper in a machine that requires paper-feeding and that includes a casing. The magnetic paper-feeding roller assembly includes a first roller and a second roller, both of which are adapted to be pivotably mounted in the casing. The first roller is made of a magnetically attractive material. The second roller produces a magnetic force to magnetically attract the first roller toward the second roller so as to maintain a predetermined gap between the first roller and the second roller.
