7.8 TONER SUPPLY
7.8.1 OVERVIEW
No. | Description | No. | Description |
1 | Toner bottle drive motor | 4 | Toner end sensor |
2 | Agitator | 5 | Toner supply motor |
3 | Sub-hopper |
Toner is supplied by a Hi-Act (High Accuracy and Clean Toner) cartridge + sub-hopper.
7.8.2 MECHANISM
Toner Supply (Toner Cartridge - Sub-hopper)
When the toner cartridge is set, the transport nozzle on the side of the unit is inserted into the bottle (Hi-Act system).
When the toner supply motor drives and the piezoelectric sensor in the sub-hopper detects there is no toner, the bottle drive motor rotates. The rotation of the bottle drive motor is transmitted to a transport coil via a drive gear, and toner in the bottle is transported horizontally. Due to the coil transport, stable toner supply/enhanced supply precision/reduction of residual toner are achieved.

No. | Description | No. | Description |
1 | Toner bottle | 7 | Transport nozzle |
2 | Coil spring | 8 | Coil spring |
3 | Shutter holder | 9 | Toner transport coil |
4 | Seal | 10 | Drive gear |
5 | Shutter | 11 | Rocking spring |
6 | Shutter | 12 | sub-hopper |
Toner transported by the coil falls directly into the sub-hopper via the transport pipe.
To prevent toner from remaining, the rocking spring in the transport pipe moves up and down together with the coil.
