Notes:
1. If the cause is the dependency on the 1st transfer bias, the residual image gradually
disappears as you decrease the value of the sub-code of this code.
2. However, the solid part of the image may become light or an uneven grain may appear on the
image if the value is too small. Check the image carefully and set the value at the point that all
the factors of the image are balanced.
