A fusing belt and three rollers comprise the fusing unit. The rollers are:
Heating roller (fusing lamps x3)
Pressure roller (fusing lamp x1)
Hot roller (no fusing lamps).
The hot roller is composed of a new, softer sponge material that applies more even
pressure during fusing. Because the hot roller is very soft, a mechanism is provided to
retract the pressure roller from the hot roller and fusing belt when the machine is not
operating.
