Toner Supply Clutch Operation
The toner supply clutch turns the toner agitator shaft to supply toner from the toner
cartridge to the development unit.
The toner supply rates in these three tables control the on/off timing of the toner supply
clutch.
When the toner supply clutch switches on, it stays on for 0.4 second. The length of the
intervals when the clutch is off is set by the percentage values shown in the diagram on the
