2-001-001
Printing  *ENG  [-2100 to -1300 / -1450 / 10 vol / step] 
Adjusts the voltage applied to the charge roller when printing. The actually 
applied voltage changes automatically as charge roller voltage correction is 
carried out. The value you set here becomes the base value on which this 
correction is carried out. 
 
2102  [Main Scn Mag. Adj]   
Adjust the image scale for main scan magnification. 
  A "+" setting stretches the image.

2201  [Deve Bias Adjust] 
2-201-001
Printing  *ENG  [-1000 to 0 / -520 / 10 vol / step] 
Adjusts the voltage applied to the development roller for printing. Image 
density becomes higher when you specify a smaller value (a greater 
absolute value). Image density becomes lower when you specify a greater 
value (a smaller absolute value).
