6.6.5 TONER SUPPLY MECHANISM
Overview
This machine uses four toner bottles [A]. Each bottle has a spiral groove [B] in it.
The toner supply motor [F] turns the toner bottle (each bottle has a separate motor).
When the toner supply drive-mechanism starts, the toner bottles turn and the
groove moves toner to the mouth of the bottle. Here, toner spills into a hopper [C].
Mylar blades turn and move the toner to an opening in the side of the hopper and
the toner falls into the development unit [D]. The quantity of toner that is added is
controlled by the length of time that the toner supply mechanism turns.
Toner End Detection
Toner end sensors [E] detect toner end conditions ( 6.2.5).
6.6.6 TONER BOTTLE DETECTION
Each toner bottle is detected by connection to the memory ID chip connector [G].
