6.8.9 TONER RECYCLING
The toner collection coil inside the toner recycling pipe [A] carries toner collected
from the drum cleaning unit into the toner separation unit [B] (above the toner
hopper).
Re-usable toner is separated here from waste toner. Sieve [C] sifts the toner, and
brush [D] inside the sieve moves the toner forward.
• Reusable toner [E] falls through the sieve into the toner hopper. A fine brush
outside the sieve prevents toner from plugging the mesh of the sieve.
• Waste toner [F] does not fall through the sieve. It is pushed through opening
[G] to the waste toner transport coil [H]. The coil moves the toner towards the
back of the machine, where it is deposited in the waste toner bottle.
The toner separation unit and waste toner transport coil [H] are connected to the
same drive shaft (driven by the development motor).
