Minolta EP1080 - Toner Bottle Vibration

9-5. Toner Bottle Vibration
When the indentations at three places on the left-hand side (as viewed when
the Toner Bottle is in position) of the Toner Bottle move past the protrusion
in the Toner Bottle Holder, the Toner Bottle is vibrated to prevent some of
the toner from remaining unconsumed in the Bottle.
