● Toner Supply Control
Toner is supplied from the Toner Container to the Developing Assembly.
This machine uses a Toner Container that has a bellows mechanism at the edge. The Toner
Bottle is rotated and the bellows section is operated by driving the Bottle Motor. At that time,
air pressure is used to supply toner to the Hopper Unit.

Supply to the Developing Assembly
Toner is supplied from the Hopper Unit
to the Developing Assembly.
Toner supply from the Hopper Unit to
the Developing Assembly is synced
with the Toner Feed Screw.
The Toner Feed Screw is turned
to supply toner to the Developing
Assembly.
The Bottle Rotation Sensor (Y/M/C/Bk) (PS06/PS07/PS08/PS09) starts while it is turned ON
at the time of feeding. Driving the Bottle Motor (YM) (M09) or the Bottle Motor (CK) (M10)
rotates the Toner Bottle, causing the flag of the Bottle Rotation Sensor to drop to the cut-off
part of the Toner Bottle as shown in the figure below, which in turn switches OFF the sensor.
When the flag then moves away from the cut-off part of the Bottle Rotation Sensor, the sensor
is switched ON.
While the Bottle Rotation Sensor is in turned OFF, 1 block's worth of toner is supplied to the
Hopper Unit.
