nE Range: 1 - 7874
G - Gain
Gain is used in Manual Style only (2P). Like a volume control, the gain modifier boosts the signal and multiplies the pixel
value. As you increase the gain, the noise in an image is also amplified.
1G No gain (default)
2G Medium gain
4G Heavy gain
8G Maximum gain
W - Target White Value
Sets the target for the median grayscale value in the captured image. For capturing close-up images of high contrast doc-
uments, 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 W - Target White Value). Delta is only available when using
Photo Style (1P). (Default = 25)
nD Range: 0 - 255
U - Update Tries
This sets the maximum number of frames the scanner should take to reach the D - Delta for Acceptance. Update Tries is
only available when using Photo Style (1P). (Default = 6)
nU Range: 0 - 10
