When the developer material is replaced, adjust the auto-toner sensor in the following procedure. If the value of 08-2707 (toner density ratio manual offset control) of the replacing developer material has been changed from "0" (default), return the sub code value of the corresponding color to "0".

1. Install the cleaner unit and developer unit.
   Notes: Do not install the toner cartridge.
2. While pressing [0] and [5] simultaneously, turn the power ON. The following message will be displayed.

   (B): Current sensor voltage (V)
   (C): Adjustment value, Humidity (%)
   (C): Adjustment value, Humidity (%)
5. When the "Current sensor voltage (V)" in (B) is converged and the "Sensor output control value (bit value)" corresponding to the value for initial developer material is displayed in (C), the adjustment is completed.
   • When the adjustment is completed, the [OK] button is displayed on the screen.
   
   
   (B): Current sensor voltage (V)
   (C): Sensor output control value (bit value)
