Put a document on the scanner or put more then one document in the Automatic Document Feeder(ADF). Make sure the scanner is switched on and open XSane. Sane will now detect the scanner and the XSane graphical interface will be started.
If Sane doesn't find a scanner XSane will show the message "no devices available". In this case restart XSane. If this message comes up again check your USB cable. if that doesn't fix it check the list again and make sure your scanner is listed as compatible with Sane.
Scanning a Document
The XSane interface has four separate windows (see image 1 below) from left to right and top to bottom:
The first window is where you can set several options which include the scanner configuration, (see image 2 below) "flatbed" or "ADF". The latter of the two is the setting for the Automatic Document Feeder. We can also define the scan quality (see image 3 below). This window is also the goto window if you are ready to save your scan. You can put in your document location and name, then hit scan. It will now scan and save the image.
The second window shows a histogram; a way to quickly see how the colors are on the scan. This is most handy when scanning in photos similar to the ones found on DSLR(Digital Single Lens Reflex) LCDs.
The third window is the preview pane; it shows a preview. After you click the "Acquire Preview" button, it also gives you a few primitive options to resize, crop and enlarge a section of the scan. (See the square on the preview pane bottom right in image 1 below.)
The fourth window gives you some margin control. It also allows you to mark "Wait for Button". This is handy when your scanner is on the other side of the room, as it is in my case. It will make XSane respond to the scan button on your scanner.
