6.3 CROSS-MIXING
This copier uses a standard cross-mixing mechanism to keep the toner and
developer evenly mixed. The developer on the turning development roller [A]
is split into two parts by the doctor blade [B]. The part that stays on the
development roller forms the magnetic brush and develops the latent image
on the drum. The part that is trimmed off by the doctor blade goes to the
backspill plate [C].
As the developer slides down the backspill plate to the agitator [D], the
mixing vanes [E] move it slightly toward the rear of the unit. Part of the
developer falls into the auger inlet and is transported to the front of the unit
by the auger [F]. As a result of this mechanism, the developer stays level in
the development unit.
