QSU (Quick Start-up) Technology
QSU reduces the operating temperature, because
of these improvements in fusing unit technology
Reduced thickness of the hot roller
Low melting-point toner
This also means that the warm-up time and
recovery time from energy saver modes are also
reduced.
Slide 70
Through major reductions in warm-up time and recovery time from energy
saver modes (Low power, Off/Sleep), QSU (Quick Start Up) Technology has
eliminated the traditional trade-off between energy saving and convenience
of speed.
The IH (induction heating) method used in the Apollon series is also a part of
this technology.
