2.8 Toner Low Detection
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
protrusion in the stirring gear.
Operation
Toner Low is detected by monitoring the time interval of the encounter of the magnet set on the
sensor lever and the magnet on the stirring bar.
Operation during Toner Full state
The stirring bar is rotated due to the mechanical transmission of energy originating from the
interlocking with the stirring gear.

Even when the magnet on the stirring bar reaches
the maximum height, the stirring bar is pushed by
the stirring gear, since the other end is being dipped
in the toner.
Operation during Toner Low state
When the stirring bar reaches the maximum height,
it falls to the minimum height due to its own weight,
since there is no resistance provided by the toner
on the other side. Because of this, the time interval
during which it is in encounter with the magnet of
the sensor lever becomes longer. By monitoring
this time interval, Toner Low can be detected.
When the Toner Low state is detected 2 times
consecutively, Toner Low is established.
When the Toner Full state is detected 2 times
consecutively, Toner Low is cancelled.
When there is no change with the toner sensor for
2 cycles (4.875 sec. x 2) or more, then the Toner
Sensor Alarm is activated.
The toner sensor is not monitored while the drum
motor is in halt.
