DEVELOPMENT AND TONER SUPPLY 15 February 2006

6.9.5 TONER SUPPLY
The ID sensor and TD sensor control toner density. The output of these two
sensors determines when to switch the toner supply clutch [A] on. The clutch
transfers drive from the development motor to the toner supply mechanism.
When the toner supply clutch turns on, the agitator [B] mixes the toner in the
hopper and sends it to the toner supply roller [C].
Toner is caught in the grooves in the toner supply roller. Then, as the grooves turn
past the opening, the toner falls into the development unit.
