7.7.2 TONER SUPPLY AND TRANSPORT MECHANISM
Rotating the toner bottle [B] transports the toner towards the rear of the machine. Each toner
bottle has an ID chip (PCB3-PCB6) that stores information for each toner bottle. The toner from
the toner bottles goes into the hopper and is agitated by the agitator [E].
Then, rotating the transport coil [D] transports the toner to the development unit. Only color
hoppers have the toner end sensor (S11-S13) [A]. The ID chip (K) (PCB3) manages the
remaining amount of black toner.
