DEVELOPMENT
6.9.5 TONER SUPPLY
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 when a toner bottle is not
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.
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.
