The slider with the two comb-like appendages on it is always vibrating.
The comb-like appendages break up any blockages of toner.
Note the two slots in the development unit.
The one on the left receives fresh toner from the cartridge.
The one on the right receives the recycled toner.
New and recycled toner are mixed together in the development unit.
Mixing auger 1 in the development unit mixes the recycled toner with fresh toner
from the bottle.
Toner adhering to the transfer roller is sent back to the drum, as we shall see in
the Transfer section of the course. This toner is in turn recycled to the
development unit. It may contain some small amounts of paper dust.
