K - Gamma Correction
Gamma measures the brightness of midtone values produced by the image. You
can brighten or darken an image using gamma correction. A higher gamma
correction yields an overall brighter image. The lower the setting, the darker the
image. The optimal setting for text images is 50K.
R - Resolution of Signature Capture Area
The resolution is the number of pixels that the scanner outputs per each minimum
bar width. The higher the value for R, the higher the quality of the image, but also
the larger the file size. Values begin at 1000. The scanner automatically inserts a
decimal point between the first and second digit. For example, use 2500 to specify
a resolution of 2.5. Set to zero when using the A and B modifiers (see
