4.5.2 Drive Mechanism
When the development clutch [D] turns on, main motor drive is transmitted to
the development drive shaft [A] and the development drive gear [B] through a
timing belt [C], and a train of gears.
The development drive gears (except for the gears in the development unit)
are helical gears. These gears are quieter than normal gears. When the PCU
is pushed in, the development drive shaft engages the development roller
gear.
