9.3.1 Toner Replenishing Mechanism
• Toner is supplied from the toner bottle to the developer mixing chamber.
1. The toner replenishing motor (M2) turns the coupling, which turns the toner bottle.
2. To regulate the amount of toner supplied from the toner bottle, there is a metering
chamber provided in the outer race of the coupling.
3. When the toner bottle turns, toner in the metering chamber drops.
4. When the toner bottle is turned again, the supply door is opened by the weight of
toner in the metering chamber and the toner drops.
5. Toner from the metering chamber is conveyed by the toner conveying screw into
the developer mixing chamber.
