Use • When there is a drop in T/C.
Setting/ 1. Call the Service Mode to the screen.

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.
