    Hi,

       at first I thought it was a problem with the driver I'm writing but
    the Windows driver didn't deliver any better results. When scanning in
    color at the highest resolution (300x600dpi), black letters on a white
    background exhibit a green "shadow" to one side and a red "shadow" to
    the other. The shadow is about 3-4 pixels high. I've put an example
    here:

    You'll have to magnify the window to see it clearly.

    I would be very happy if someone who is a bit more experienced with
    scanners than I am could look at this and tell me if this would be
    considered "normal" in a medium-priced scanner (Fujitsu M3091, ca.
    USD 800) or if I that should be considered a fault in this specific
    model and I should send it back to the shop for an exchange?

    Thanks in advance,
    Frederik
