Please note that the enhancements are effective, only when new Developer, Developer Units 
and Engine Firmware have been installed/upgraded. 
 
If the wrong combination is used (old type DV unit and new type Developer), it will not be 
effective and will cause copy quality problems (DV particles will attach to the drum).
