When the toner bottle is set, the transport nozzle on the side of the unit is inserted into the bottle (Hi-Act system).
If the piezoelectric sensor in the sub-hopper detects there is no toner when the toner supply motor starts, the toner bottle drive motor rotates *1. The rotation of the toner 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.
*1 As the default, the period of rotation is set to 0.9 sec in SP3-161-001 to 004 (Bottle Drive: Set Drive ON Time).

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.
