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 a low humidity environment (e.g. winter in North America or
