Abstract
An approach for managing the thermal stresses introduced into a heated belt of the type used for transporting media through an ink-jet printer so that the portion of the belt that transports the print media through the print zone does not buckle. The temperature of the belt is controlled to ensure that any temperature gradient produced in the belt is not great enough to buckle the belt in the print zone. Put another way, the temperature profile in the belt is substantially flat. As another approach to the present invention, the belt is bent in the print zone to create a force component in the belt for resisting thermal stress and to increase the belt area moment to greatly enhance resistance to buckling of the belt.
