Toner Supply

Toner Bottle Replenishment Mechanism
When a toner bottle is placed in the bottle holder unit [A] and the unit is pushed in
completely, toner shutter [B] moves against the side [C] of the PCU. When the toner bottle
holder lever [D] is put back in the original position, the cap [E] on the toner bottle is pulled
away and kept in place by the chuck [F].
The toner supply mechanism transports toner from the bottle to the development unit. The
toner bottle has a spiral groove [G] that helps move toner to the development unit.
To add a new toner bottle, first lift the toner bottle holder. When this is done, the chuck
releases the toner bottle cap into its proper position to prevent toner from scattering.
Then, when the bottle holder unit is pulled out to add a new toner bottle, the toner shutter
shuts to block the opening as a result of pressure from a spring.
