Toner replenishing overview

• The toner replenishing mechanism incorporated in this machine has a two-step replen-
ishing structure, one replenishing the toner hopper with toner from the toner cartridge
and the other replenishing the developing unit with toner from the toner hopper.
• Only the toner cartridge/K incorporates the auto refining developing system. The toner
cartridge/K is packed with both toner and carrier and the developing unit/K is replenished
with fresh carrier at the same time that it is replenished with toner. Excess carrier in the
developing unit/K is discharged, thereby inhibiting carrier left in the developing unit/K
from being deteriorated and maintaining stable image quality for an extended period of
time.
• For details of the auto refining developing system, see "Developing section".
