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].
