A3.1.10 Toner Low Detection
l
Device
The Toner Low Detection device consists of a stirring gear which rotates at a constant rate, a stirring bar and a magnet on the stirring bar. The stirring bar rotation
is driven by the link to the gouged portion in the stirring gear.
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.
