Toner bottle replenishment mechanism

[G]
[E]
When the toner bottle is installed in the bottle holder [A], pin [B] slides up the side
of the PCU [C], pulling out the toner shutter [D]. When the toner bottle holder lever
[E] is returned to its original position, the cap [F] pulls away and is kept in place by
the chuck [G].
The toner bottle holder lever [E] cannot be lowered:
• Until a toner bottle is installed in the holder. This prevents toner falling out of the
holder unit as a result of lowering the handle with no toner bottle installed.
• Until the holder and bottle have been pushed into the machine completely and
locked in place. Instruct the customer to always follow the bottle replacement
instructions of the new decal attached to the toner bottle.
The toner bottle has a spiral groove [H], which rotates the bottle to move toner to
the development unit. When the bottle holder unit is pulled out, the chuck [G]
releases the toner bottle cap and the toner shutter [D] closes and blocks the
opening.
