Yes, other people have reported these same characteristics of the
CCD in the Canon FS2710.
I've been saying on this mailing list for more than a year that
overexposing the CCD would have charge bleeding problems.
This limits the usefulness of the long exposure feature on
some scanners. It's a hardware limitation, and there's not a
lot I can do to work around it.
