5.3.2 Toner replenishing mechanism

• The developing motor is energized by monitoring the condition of the toner level sensor for each color of toner. Toner is then supplied from
the toner cartridge to the imaging unit as necessary.
• Rotation of the developing motor transmits the drive to the drive shaft via each gear.
• Rotation of the drive shaft then transmits the drive to the supply screw of the toner cartridge.
• The drive of the supply screw is controlled by the toner supply clutch of each toner cartridge. The supply screw is operated when the toner
supply clutch is energized.

5.3.3 Toner replenishing control

• The toner level sensor is used to detect the amount of toner in the pre-agitation section (imaging unit), so that the main body can determine
whether to replenish the toner or not.
• During developing drive, the toner level sensor measures the amount of toner. If the value detected by the toner level sensor is a
predetermined value in V or less, the main body determines that there is a short supply of toner and replenish the toner as necessary.
• When the value detected by the toner level sensor reaches the predetermined value or more, the toner replenishing sequence is stopped.
