Previewing
The preview scan is a trial scan performed before the final scan that encompasses
the entire scanable area of the document glass. The preview image is shown in the
preview window. Use this image to specify a scan area and adjust the scan settings
for the image.
Operating Procedures
Click on the [Preview] button.
• The image will be scanned and appear in the preview window.
Hint
• To change the size of the preview window, use the [Window Size] settings
in the Preview Window Settings dialog (p. 26) .
Caution
• The Dynamic Preview function enables changes to settings, such as the
scan mode and brightness, to be immediately reflected in the preview
image.
• Nevertheless, the preview image provides only an approximation of the
scan and the final results may differ to some degree from it.
• If the color balance of the preview image is markedly different from the
original or color appears in portions of the image that should be white,
calibrate the scanner by selecting [Preferences] and [Calibration]
(p. 27) .
Calibrating the scanner sets the correct white balance.
