Scan to Application
Depending on the software applications that you have installed and selected for
Scan Button, different buttons representing the applications will also appear on the
Scan Button toolbar. You can click the button to scan and import the scanned
image into the application directly. For example, if you click the PhotoExpress
button, the scanner will start to scan the original automatically. When
scanning is completed, PhotoExpress will be activated automatically and you
can begin to edit the image.
In addition to the buttons on the Scan Button toolbar, you can also use the Quick
Scan function by double-clicking the Scan Button system icon to execute the action
you specified in General tab in the Setting dialogue box.
