NOTE:
B = Development bias adjustment factor, selected with SP2-201-001.
BP = Correction to the development bias used for making for V
SP
patterns, selected with SP2-203.
BL = The value of the development bias that was reached during the most recently performed forced V
L
detection routine.
V
BL
(ID) = ID compensation factor based on the current ID correction used for making V
SP
patterns.
C = Correction to the drum charge voltage, selected with SP2-001.
CP = Correction to the drum charge voltage for maknig V
SP
patterns, selected with SP2-003.
Vexp = Exposure lamp voltage, selected with SP4-001.
