6.6 TONER SUPPLY

6.6.1 Toner Bottle Replenishment Mechanism

When a toner cartridge is placed on the holder unit [A] and pushed back in

completely, the following procedures are automatically performed to supply

toner to the toner supply unit.

•

The cap [B] remaining on the toner bottle is pulled away and kept by the

chuck [C] away from the movement of the roller [D], which rides along

the curved rail.

•

The toner shutter lever [E] meets the bracket [F] on the copier frame and

the toner shutter [G], which covers the hole above the toner supply unit

opening, is opened.

The bottle drive mechanism transports toner from the bottle to the toner

supply unit [H]. A worm gear on the bottle drive motor [I] drives this

mechanism. The toner bottle has a spiral groove [J] that helps move toner to

the toner supply unit.

When the holder unit is pulled out to add new toner, the following procedures

are performed automatically to prevent toner from scattering.

•

The chuck releases the toner bottle cap into its proper position.

•

The toner shutter shuts the opening as a result of the pressure of the

torsion spring [K].
