013-014 Threshold for image density rank on the image transfer belt.
013 T Rank 1 Threshold *ENG
[-1 to 0 / -0.2 / 0.01 V/step]
014 T Rank 2 Threshold *ENG

3241 [Background Potential Setting]
001 Coefficient: Bk *ENG
002 Coefficient: M *ENG
003 Coefficient: C *ENG
004 Coefficient: Y *ENG
These are parameters for calculating the
charge bias referring to the development
bias at process control.
[-1000 to 1000 / 0 / 1 /step]
DC charge bias = Development bias x (1 +
0.001 x these vales) + SP3-241-005 to
-008
005 Offset: Bk *ENG
006 Offset: M *ENG
007 Offset: C *ENG
008 Offset: Y *ENG
These are additional values for calculating
the charge bias referring to the
development bias at process control.
[0 to 255 / 140 / 1 V/step]
DC charge bias = Development bias x (1 +
0.001 x SP3-241-001 to -004) + these
values
