When a toner-empty condition is detected in the Sub Hopper, Main Hopper
Toner Replenishing Motor M14 is energized to turn the Toner Bottle, thereby
supplying toner from the Main Hopper to Sub Hopper.
<Mechanism>
= Toner Replenishing to Sub Hopper =
Main Hopper Toner Replenishing Motor M14 is energized.
The coupling is turned by a gear train.
Since the two pins on the Toner Bottle fit into the slots in the
coupling, the coupling and Toner Bottle are turned together.
When the Toner Bottle turns, toner in the Toner Bottle is guided along
the spiral ridge in the bottle towards the front end of the bottle. During
rotation, protrusion A causes the bottle to vibrate, ensuring smooth
movement of the toner through the bottle.
Since the Toner Supply Port in the Toner Bottle is aligned with the Toner
Supply Hole in the coupling, toner in the Toner Bottle drops down as the
supply hole becomes located at the bottom.
