The Fusing Roller (Heating Roller/Fusing Pressure Roller) is driven by
the Fusing Motor (M4). The Fusing Motor (M4) drives the Heating
Roller. The Fusing Pressure Roller rotates along with the Heating
Roller.
In order to avoid fusing error, the rotation speed of the Fusing Roller is
to be set to one of 2 levels according to the paper type or the print mode.
