The fusing unit uses the QSU system. (QSU: Quick Start Up).
The heat from the fusing lamp [B] is reflected by the reflector [C] and heats the fusing sleeve belt [D].
The temperature at both ends of the fusing lamp is lower than the middle.
The fusing sleeve belt itself has no drive mechanism; the pressure roller drives it. The nip pad [E] at the sleeve
belt side is pushed against the pressure roller and keeps the nip width on the sleeve belt.
