Changing the Resolution
option
Resolution (dots per inch) — allows you to select the scanning
resolution. 300 dpi is optimal for creating PDF files. Choices are: 75,
100, 150, 200, 240, 300, 400, and 600.
Changing the Black and
White Adjustment option
Black and White Adjustment — allows you to change the Contrast
and Threshold values. This option is only available if your Scan As
selection is Black and White. When you select the Black and White
Adjustment icon, the Black and White Adjustment screen will be
displayed allowing you to select either Contrast or Threshold.
If you selected Best (iThresholding) on the Scan As screen, only the
Contrast value can be changed. If you selected Normal (ATP), both
Contrast and Threshold can be changed.
• When you make a selection, either the Contrast or Threshold
Adjustment screen will be displayed. Use the Up and Down arrows to
adjust the value, then click the green button to the left of the number
to save the new value.
