4.5.4 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
hopper [A]. A worm gear [B] on the bottle drive motor drives this mechanism.
The toner bottle has a spiral groove [C] that helps move the toner to the toner
hopper.
To prevent toner from scattering when the toner bottle is removed from the
holder, toner shutter [D] which covers the hole [E] is installed on the toner
bottle.
When the toner is set on the holder and the lever is lowered, the toner shutter
[D] opens to supply toner to the toner hopper.
The bottle drive motor turns on 0.7 seconds when the toner end sensor turns
on twice continually.
