Charge bias (DC component)  is automatically adjusted during process control; 
therefore, adjusting thes e settings does not effect while process control mode 
(SP3-041-1 Default: ON) is activated.  When deactivating process control mode 
with SP3-041-1, the values in thes e SP modes are used for printing.
