Abstract: A feeding system in a printing apparatus is disclosed. For example, the feeding system includes a feed roll, a retard roll, a movable arm, a spring and a temperature dependent flexible material. The movable arm is coupled to the retard roll. The spring is coupled to the movable arm. The temperature dependent flexible material is located below the spring to move the retard roll towards the feed roll via the spring coupled to the end of the arm to maintain a nip force applied by the retard roll against the feed roll as a temperature in a location of the printing apparatus changes.

Abstract: Various methods and apparatus relating to a media interaction device drive system having at least one reduced dimension are disclosed.

Abstract: A roller support apparatus includes a compression coil spring, lever, bias canceling member, roller holder, and support. The compression coil spring biases the distribution roller in a direction to come close to the oscillating roller. The lever transmits a biasing force of the compression coil spring to the distribution roller. The bias canceling member cancels bias of the compression coil spring. The roller holder rotatable supports the distribution roller and pivots in accordance with movement of the lever. The support is provided to the roller holder and engages with a shaft portion of the distribution roller. The support brings the outer surface of the distribution roller into contact with the outer surface of the oscillating roller in accordance with pivot motion of the roller holder.
