The main motor [A] drives the fusing unit through a gear train and drives the paper
exit rollers [B] through a timing belt [C].
The fusing unit release mechanism automatically disengages the fusing unit drive
gear [D] when the right cover [E] is opened. This allows the fusing unit drive gear to
rotate freely so that misfed paper can easily be removed.
Also, the fusing drive is released by the fusing drive release solenoid [F]. To reduce
the warming up time, the machine cuts the drive to the fusing unit during warming
up. Just after the main switch is turned on, this solenoid is energized and the fusing
unit drive gear [D] is disengaged.
However, the fusing unit drive is not released when the temperature is lower than
15°C.
