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.
• Calibration automatically starts when [Preview] or [Scan] button is clicked.
Do not lift the document cover while calibration is in process.
➟
When the amount of light of the lamp inside the scanner is insufficient, the
message “Now adjusting lamp…” may be displayed. Wait as is, until the
amount of light increases enough. If you click the [Cancel] button in this
dialog, the preview scan will be executed with insufficient amount of light, and
the previewed image will not have the correct color balance. Click the [Cancel]
button only if you need to obtain the previewed image quickly although
without the correct color balance, before the amount of light is sufficient.
