Procedure
By adjusting the exposure level of the center density, the other copy density levels (density levels 1, 2, 4, 5) can
be automatically calculated and adjusted.
The gamma curve (gradient) is fixed and cannot be changed. By changing the adjustment value, however, the
gamma curve is shifted (with the fixed gradient).
Therefore, the overall copy density is changed.
The above adjustment is made for each copy mode.
Each copy mode and each copy density level (5 steps) have their own gamma curve (gradient). The adjustment
value can be set in the range of 0 ~ 99.
