I don't know what software you're using, but I would advise never EVER using
pdf2djvu, or the Win32 version "pdf2djvu GUI" for scanned documents; it's
actually worse than doing nothing! All it does is shrink the source file to
100dpi and run wavelet compression on the result. This is NOT a real DjVu file.
The only Windows software even worth looking at, in my experience, is the
original Lizardtech "Document Express" software. It's not as tweakable as the
stuff I'm working with (which requires a *nix of some sort), but it's much
faster and it produces results that are quite good. It is, after all, the same
program the professionals use.
