Ubuntu :: Easy Way Of Using Controls In Iscan Or AcquireImages?

I have an Epson Perfection V200 Photo scanner.It works as you would expect in XP.In Ubuntu, using the flatbed, not the transparency scan, real whites (white paper backgrounds) come out noticeably blue.This is annoying anyway & especially when printing afterwards.Note that even the scanner white background (left) is blue.The dark blue (right) is where the paper pulls away from the glass when it overlaps the scan area.Many of the other applications have several colour-correction tools, but I didn't find any simple way of using them to fix my problem.

Is this a common problem?Is there any way I can dial it out, once & for all?Or an easy way of using the controls in iscan or AcquireImages?
