selected. If you are in First Page Mode when an exception occurs, changes to the

2 Adjust the movable angle control arm until the image is straight:

- or -
b Position the mouse over the vertical arm, click, and hold. The cursor will
change to a hand.
c Drag the arm counter-clockwise to rotate the image to the left, or
clockwise to rotate it to the right. You can rotate the image up to 360
degrees.
3 Using the Fine Angle Adjustment slider, you can fine-tune the deskew angle
in single degree, or partial degree, increments, as follows:
a By moving the slider all the way to the left, you select a complete one-
degree, counter-clockwise angle adjustment.
b By moving the slider all the way to the right, you select a complete one-
degree, clockwise angle adjustment.
c By moving the slider to a position in between the leftmost or rightmost
setting, you select an angle shift that is less than a full degree. Each line on
the slider scale represents 5 percent of one degree.
When you use a scanner that produces white borders around the scanned images, the
deskew correction is calculated based on horizontal and vertical text lines in the
image. When you use a scanner that produces black borders around the images, VRS
switches to using black borders and not the content of the document to determine the
skew correction with faster and better results.
When you use a scanner that produces black borders, the Auto Crop option is
enabled. Select this option to automatically crop every page to its original size. Auto
Crop is important for a precise registration of each image in order to perform accurate
optical character recognition (OCR).
