● 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.

Title Supply to the Hopper
Description Toner is supplied from the Toner
Container to the Hopper Unit.
Supply timing Toner is supplied when supply is
determined necessary from the result
of ATR control.
Operation of the The Bottle Motor (YM) (M09) and the
host machine Bottle Motor (CK) (M10) are driven*.
*) The supply amount is determined based on the output value at the time of ATR Sensor
output and the time of video count.
