B.3.3.1 Toner Low Detection

l
Composition
The device consists of the stirring gear which rotates at a constant rate, the stirring bar and the magnet on the stirring bar. The stirring bar rotates through the link
on the protrusion in the stirring gear.
The configuration of stirring bar in the figure below may differ. The principle of toner detection, however, remains the same.
l
Operation
Toner Low is detected by monitoring the time interval of the encounter of the magnet set on the sensor plate and the magnet on the stirring bar.
Operation during Toner Full state
l
The stirring bar rotates due to the
mechanical transmission of energy
originating from the interlocking with the
stirring gear.
l
Even when the magnet on the stirring bar
reaches the maximum height, the stirring
bar is pushed by the stirring
gear, since the other side is being dipped in
the toner.
