I've senn this working with another ImageClass scanner. Maybe somebody
else can confirm this?

The scan resolutions are restricted by hardware. If you need another
scan resolution you must use an external image converter program. But
you won't win anything if you increase the scan resolution. No program
can create contents which isn't available on the 600dpi scan.

At the frontend you can set the desired scan area. E.g. in xsane you can
set the scan borders in a preview window.


Hope this helps.
