When the toner bottle [A] is set, the transport nozzle [B] on the side of the main machine is inserted into the bottle (Hi-ACT system).
The drive of the toner supply motor is transmitted to the toner transport coil [F] through the drive gear [E], which transports the toner in the bottle horizontally. Transporting by a coil provides a stable and accurate toner supply and low toner remaining.
Toner transported by the coil [A] falls directly into the development unit from the sub-hopper via the transport pipe [B]. To prevent toner from remaining, a coil is provided in the transport pipe.
When the PCDU is put in the machine, the sub-hopper [C] slides the shutter [D] on the bottle assembly and the toner goes to the entrance [E] of the development unit.
