VCONT-C
Adj of C-color contrast potential
Details
To adjust the contrast potential for C.
As the value is incremented by 1, the contrast potential changes by 10V.

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 Japan),
