Click 

Show main UI

 to bring the main scanner interface in front of the preview window for 

you to adjust the scan settings. 

There are some settings in the main interface, such as brightness and contrast, which will 
immediately update the preview image after you adjust the setting. Other settings, such as 
changing from color scanning to black and white scanning, will not automatically update the 
sample image.

If you select any of the document image adjustment options, such as an option to 
automatically crop, straighten or rotate an image, it will not show in the sample image 
preview. The preview window displays an unaltered view of the item size and position in the 
scanner. Any document image adjustment options will be used while scanning and saving 
images.

5.

After you adjust the scan settings, click 

Refresh preview

 to get a new sample image that 

reflects the most current settings in the main interface.

6.

When you are happy with the sample image, you can click 

Scan

 in the preview window or in 

the main interface to scan and save the image with the current scan settings.
