- Length Table -
If the page becomes longer than 1189 mm (46.8"), the machine changes to the Length Table for the
remaining part of the page.
But, if no toner was supplied before the start of the copy job, the quantity of toner was sufficient at that time.
Because of this, the machine does not change to the Length Table.
The Length Table ignores the Vsp/Vsg ratio. Toner is supplied at a set rate. This rate is controlled by the
toner supply level set with SP2208-1.

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 s The length of the intervals when the clutch
is off is set by the percentage values shown in the diagram on the next page.
