DEVELOPMENT

6.12.3 DRIVE
The gears in the development unit are driven by the development drive gear [A]
when the development motor [B] (a dc servomotor) turns.
The gears in the toner hopper are driven by the toner supply roller drive gear [C],
which is connected to the toner supply motor [D].
A one-way clutch on the paddle roller knob [E] prevents counter-clockwise rotation
of the paddle roller.
A dedicated dc motor [F] (hopper agitator motor) is provided for the agitator to:
• Reduce the amount of time for toner filling after development unit replacement
• Reduce the load on the drive components
• To better control toner transport by the toner supply pump in the toner hopper
