Recovered Toner Supply Mechanism - Toshiba e-STUDIO163 Service Manual

However, the shorter the period described above is set, the more frequently the toner in the cartridge
may run out before the sign of the near-empty status of the toner appears because the way the toner
remains in the cartridge differs every time.
When the value of the toner near-empty status threshold setting (08-****) is set at "3", neither of the car-
tridge detecting function (including detection of the use of a genuine TOSHIBA cartridge) and the toner
remaining check function is enabled.

Recovered toner supply mechanism

The toner scraped off by the drum cleaning blade is transported by the toner recovery auger and the
toner recycling auger to be recycled, and then returned into the developer unit. Then the recovered
toner in the developer unit is mixed by the developer material using the mixer-3. The mixer-3 is
mounted exclusively for the recovered toner to mix it in a sufficient period of time. On the other hand,
the (fresh) toner transported from the toner cartridge into the developer unit is mixed by the mixer-2.
Then the (fresh) toner and the recovered toner are mixed together and further transported to the mixer-
1. They are further mixed by the mixer-1 and transported to the developer sleeve.
