9-6. 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 16 times and compares each with the preset level.
3. If eight or more readings out of the total 16 are lower than the preset level, a Toner
Replenishing signal is output.
4. Toner Replenishing Motor M8 is turned one complete turn for each Toner
Replenishing signal (which is equivalent to a supply of 0.45 g toner).
*The readings taken while M8 is turning (it takes 5 seconds for M8 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 M8 is turning; but,
those readings are ignored.
