Auto refining developing system
• Only the developing unit/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.
