VCONT-Y
Adj of Y-color contrast potential
Lv.2 Details
To adjust the contrast potential for Y.
As the value is incremented by 1, the contrast potential changes by
10V.
+: Image becomes darker.
-: Image becomes lighter.
When the value is too large, paper winds around the Fixing Roller or
a transfer failure occurs.
In principle, the adjustment of the density should be performed in
Settings/Registration> Adjustment/Maintenance> Adjust Image
Quality> Density Adjustment Mode.
Use case
When adjusting the density of D-max control in the case that an
image density failure occurs
Adj/set/operate method 1) Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
