want to scan A3

I have an A3 printer scanner. Can I tell autosplitter to scan across the full A3 please?

Hello Judith. The software already always uses the maximum available scanning area. If it doesn't work, try to see the scanner selection dialog. If you have 2 entries for the scanner (TWAIN+WIA), try both to see if some of these work. Refreshing the scanner driver from the manufacturer's website can also help.
