Recovered toner supply mechanism

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