Use • When there is a drop in T/C.
Adjustment 1. Call the Tech. Rep. Mode to the screen.

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 refer-
ence value, only a developer agitation sequence is carried out.
