15-5. Toner Bottle Vibration

When the indentations at three places near the left end (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.

15-6. Toner Replenishing Control
1. The ATDC Sensor installed in the Imaging Unit reads the toner-to-carrier ratio of the
developer in the Developer Mixing Chamber for each copy cycle.
2. It samples the ratio for 290 msec.
3. If the average ratio reading is lower than the target level, a Toner Replenishing signal is
output.
4. The Toner Replenishing Motor is turned one complete turn for each Toner Replenishing
signal (which is equivalent to a supply of 0.3 to 0.6 g toner).
The readings taken while the Toner Replenishing Motor is turning (it takes 5 seconds for
the Toner Replenishing Motor to turn one complete turn) are ignored. This means that, in
a multi-copy cycle, the ATDC Sensor may take readings as the next copy cycle is started
while the Toner Replenishing Motor is turning; but, those readings are ignored.
