A roll fusing apparatus for effectively heating and fusing quality toner images on various different thicknesses of substrates is described. The apparatus includes a frame, a heated fuser roller having a first end and a second end respectively mounted to the frame; a pressure device mounted to the frame and forming a fusing nip with the heated fuser roller, the heated fuser roller and the pressure device being movable for receiving, heating and applying a nip force to toner images being moved through the fusing nip on various different thicknesses of substrates; a rotatable cam providing a varying amount of pressure to the pressure device in response to the thickness of the substrate being fed into the nip of the fusing apparatus; a drive shaft for rotating the cam; and a controller for selectively moving the cam in response to the thickness of the substrate.
