DMAX-C Adj D-max ctrl C-color dens target VL
Lv.2 Details An image failure may occur because the density target value of D-max
control becomes out of the setting table due to environment change.
Adjust the offset of the C-color density target value of D-max control.
Use case When an image failure occurs due to environment change
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and press
OK key.
Display/adj/set range -128 to 128

Unit is changed, the TD ratio is also changed.
Decrease the value when density increase occurs, and increase the
value when fogging occurs.
Use case When an image failure (density failure, fogging, carrier adherence,
etc.) occurs
Adj/set/operate method 1) Enter the setting value (switch negative/positive by -/+ key) and
