Fusing
SM 7-75 D0CA/D0C9/D0C8/D0CB
7.11.2 FUSING MECHANISM
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 [F] it. The nip
pad [E] at the sleeve belt side is pushed against the pressure roller [F] and keeps the nip width
on the sleeve belt.
