6.3.3 Toner hopper drive
• Rotation of the toner supply motor causes the toner agitating blade and toner conveying screw inside the toner hopper to rotate.
• Toner conveyed into the toner hopper is agitated by the toner agitating blade.
• As the toner conveying screw rotates, toner is conveyed onto the toner replenishing port located at the front side inside the toner hopper,
so that the toner is fed into the developing unit via the toner replenishing pipe.
The following illustration is for bizhub C368/C308/C258.

6.4 Operation
6.4.1 Toner replenishing overview
• The toner replenishing mechanism in this machine has a two-step replenishing structure. One is replenishing the toner hopper with the
toner from the toner cartridge. The other one is replenishing the developing unit with the toner from the toner hopper.
• The toner cartridge incorporates the auto refining developing system for all colors.
• The interior of the toner cartridge is packed with both toner and carrier. The developing unit is replenished with fresh carrier at the same
time of replenishing the toner. Excess carrier in the developing unit is discharged, thereby inhibiting carrier left in the developing unit from
being deteriorated and maintaining stable image quality for an extended period of time.
• For details of the auto refining developing system, see "
