Yes, but 8cm x 10cm is much smaller than the default, which is 15 x 10 cm,
so this might not be the problem.
Sorry if these numbers seem a little weird. I could make the default
be some standard page size, if this actually is the problem. (the current
default is the size of a typical photograph in Canada; it's what I bought
the scanner for originally and it seemed like a good default at the time :)
