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
Example of Gain at 1G:

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)
n W Range: 0 - 255
Example of White Value at 75W:

D - Delta for Acceptance

This sets the allowable range for the white value setting (see
available when using Photo Style (1P). (Default = 25)
n D Range: 0 - 255

U - Update Tries

This sets the maximum number of frames the document reader should take to reach the
Acceptance. Update Tries is only available when using Photo Style (1P). (Default = 6)
n U Range: 0 - 10
1 - 4
