Fusing temperature control

• To fuse the toner image on the media (image yet to be permanently fixed) properly into
the media, the heater lamps are turned ON and OFF as necessary to bring the fusing
temperature to an appropriate level.
• Thermistors are used to detect the surface temperature of the Fusing roller. The heater
lamps are then turned ON and OFF as necessary to achieve the set temperature.
• The control temperature in the print command wait state is called the standby tempera-
ture, while that for permanently fix the toner image on media into the media is called the
print temperature.
