W - Target White Value
Sets the target for the median grayscale value in the captured image. For
capturing close-up images of high contrast documents, a lower setting,
such as 75, is recommended. Higher settings result in longer exposure
times and brighter images, but if the setting is too high, the image may be
overexposed. Target White Value is only available when using Photo Style
(1P).
(Default = 125)
nW Range: 0 - 255
D - Delta for Acceptance
This sets the allowable range for the white value setting (see
). Delta is only available when using Photo Style (1P).
(Default = 25)

This sets the maximum number of frames the scanner should take to reach
the
. Update Tries is only available when using
Photo Style (1P).
(Default = 6)
nU Range: 0 - 10
% - Target Set Point Percentage
Sets the target point for the light and dark values in the captured image. A
setting of 75% means 75% of the pixels are at or below the target white
value, and 25% of the pixels are above the target white value. Altering this
setting from the default is not recommended under normal circumstances.
