Bottle Drive Mechanism - Ricoh FT5540 Service Manual

6.2 BOTTLE DRIVE MECHANISM

For easy access, the toner bottle is just inside the front cover. The bottle is positioned
horizontally.
The bottle drive mechanism transports toner from the bottle to the toner tank. A worm gear
[A] on the front end of the toner supply roller [B] drives this mechanism.
When the toner supply roller turns, the worm gear turns the toner bottle [C] via the worm
wheel, the bottle drive gear, and the bottle gear. The toner bottle has a spiral groove that
helps move toner to the toner inlet.
To prevent toner from scattering when the toner bottle is lowered, a rack [D] and pinion [E]
system closes the toner shutter [F].
At the toner inlet section, the toner agitator [G] has a spiral shape to move the toner to the
toner tank cavity.
