Dear GregC
according to the <a href="http://www.microtek.nl/Product.php?ThisPage=&Product=Detail&P_Id=92">specs of the Artixscan 120tf</a>
this scanner support 6x9 cm scans.
SilverFast does support that format, too.
However, you'd need to select the appropriate format before you can expand the scan frame marquee accordingly.
If you got further problems with this, please don't hesitate to contact LaserSoft Imaging support staff:

Thanks in advance for your co-operation.
Kind regards
