A heating roller (1) heats the fusing belt which transfers heat to the hot roller (2), which applies heat to the paper and toner in the nip of the hot roller and pressure roller (3). Web fabric (4) is used to both clean and lubricate the surface of the fusing belt. Two cams (5) below the shaft of the pressure roller raise and lower the roller to vary the pressure at the nip. The cams are down when the machine is idle to relieve pressure at the nip (this prevents deformation of the rollers).
