DEVELOPMENT

Toner Transport
Each toner attraction pump has the same mechanism. The pump (toner attraction
pump) [A], has the following components:
• Toner supply clutch [B]
• Rubber tube [C]
• Rotor [D]
The above components attract the toner in the toner transport tube [E] toward the
development unit.
The toner supply clutch drives the rotor, which draws the toner in from the cartridge
and passes it to the development unit. When supplying toner, the clutch turns on
and off as many times as necessary to supply the necessary amount of toner. The
amount of toner depends on the results of toner supply control.
Motor drive comes from the development drive motors.
