You need to scan at 1bpp, not grayscale. When you are

grayscale to 1bpp, you are probably getting dithering (a pseudo-random
scattering of black and white pixels) in order to approximate the
original grays at the edges of characters. This dithering will ruin the
achievable compression in G4, which is a fax algorithm optimised for
runs of white and black pixels.
Ah, ok - I was using dithering.
Now I've gotten the images down to 28 KB G4 tiffs, which become 40 KB pdfs.
Here's the first three pages, a 152 KB pdf file: <www.applefritter.com/
temp/sample.pdf>. Any reservations about the quality of the file, or
anything else, before I start doing a whole bunch more just like this?
Thanks!
