2.2.5. Toner Supply
This machine uses monocomponent toner, which is composed of resin and
ferrite. The toner mixing bar [A] stirs and carries toner to the toner supply
roller [B]. The toner supply roller supplies toner to the development unit.
The main motor [C] drives the toner supply mechanism through a gear train.
Toner is supplied to the development unit from the outer openings [D, E] of
the CTM. The spiral mechanism [F] on the toner supply bar distributes toner
through the development unit.
Openings in the central area of the CTM [G] allow toner to circulate upwards
from the development unit. This circulation prevents excessive toner supply
to the development unit and ensures that the toner remains fresh (this helps
to prevent blurred images).
