A snapfit for fixing a consumable roller such as a pickup roller to a corresponding shaft, facilitating the replacement of the roller. The snapfit includes a first fixing member and a second fixing member substantially symmetrical to each other with each having a catching portion formed at a first side for firmly engaging the shaft. The snapfit further includes a pressing portion formed at a second side, and preferably a hinge joint connecting the first and the second fixing members approximately in the middle of the first and the second fixing members. The first and the second fixing members may swing on the hinge joint toward or away from each other. The hinge joint may be a resilient to support the first and the second fixing members in a direction that closes the catching portions of the first and the second fixing members.
