Hi Sam,

Thanks for the tip, but I'm already scanning as a positive in 16bit mode.

I can say that moving my palm pilot away from the scanner and turning off my
LJIII tank of a printer that sits next to the scanner seems to have minimized
the problem -- results comparable to doing a multi-pass scan. Must have been
some kind of interference.
