2.2.5 TONER SUPPLY
This machine uses mono-component toner, composed of resin and ferrite. The
toner mixing bar [A] stirs and carries toner to the toner application roller [B]. The
toner application roller supplies toner to the development roller [C].
The main motor drives the toner supply mechanism through a gear train.
Since the toner tank and the development unit is composed in one unit, initial toner
supply mode is not required for this machine.
