scan area does not match preview selection

[jimav]

Using Brother MFC-9340CDW to scan.

After selecting a region in the Preview window, "Scan" scans the wrong area. The scanned area is "kind of" related to the selcted area, but off significantly. The scan includes extra area to the upper left, and truncates ares from the lower right.

Please see attached screen shot, which shows the preview window and scan results.
Note that the dashed line selected in the preview does not correspond to the area actually scanned.

STEPS TO REPRODUCE:

1. Install brother MFC-9340CDW :-)
2. Put newsprint or similar on flat bed.

3. Start xsane. In preview window, select +zoom and click somewhere to zoom in.
   Then right-click to stop zoom function, and left-click-drag to select a small scan area (about 1x1 inches)

4. Click Scan button in the main window.

RESULTS: The scan contains the wrong part of the image

EXPECTED RESULT: Scan should contain the area shown in the dotted box in the Preview window.

Status changed to 'Confirmed' because the bug affects multiple users.

I can reproduce this problem using a Epson Perfection V30. I have to select a bigger scan area, and then manually crop every picture using Gimp or another picture editor.
