In electrophotography, a toner image (Figs. 1-3 below) is first formed on the photoreceptor and then transferred to paper (Fig. 4). Marketing is then completed using heat to fix the toner on t;he paper (Fig. 5). Heat fixing is typically applied by passing a piece of paper between a heating roll and a pressurizing roll, but if the pressure between the two rolls is not uniform, defective fixing or distortions in the papers may occur. In addition, the heating or pressurizing roll may become significantly worn after extensive use, thereby causing mechanical vibrations that alter the intial conditions of the device, resulting again in fixing defects or paper distortions.
