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.
When the toner bottle holder is released, the chuck releases the toner bottle cap
into its proper position to prevent toner from scattering.
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.
