Toner Supply
Toner Bottle Replenishment Mechanism
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 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.
