The PCU uses 2 mixing augers, [A] and [B], to keep the developer evenly
mixed. Mixing auger 1 [A] transports excess developer, scraped off the
development roller [C] by the doctor blade, towards the front of the machine.
Mixing auger 2 [B] returns the excess developer, along with new toner, to the
rear of the mixing assembly. Here the developer is reapplied to the
development roller.
