1. Call the Service Mode to the screen.
2. Touch these keys in this order: [Imaging Process Adjustment] → [TCR Toner Supply].
3. Select the color, for which supply of toner is to be replenished.
4. Pressing the Start key will let the machine detect the current toner density and; if the
density is lower than a reference value, a toner replenishing sequence and then a
developer agitation sequence are run.
5. These sequences are repeated up to a maximum of four times until the toner density
reaches the reference value. If the toner density is found to be higher than the reference
value, only a developer agitation sequence is carried out.

I don't have the c351 manual,but i think this section above is on all colors
