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.
