Whoa, well if that is your requirement, I am apparently on the high side. Well, not really, since the SCD manual is grayscale. I let the scanner grab it at whatever pixels it wanted to at 300 dpi, auto crop it, and then I grayscaled, downsized (by about half) and compressed them (slightly).
The original size of the manual is 10.25" x 7.25". I don't know if that matters, but the info is there for when you use Adobe PDFerizer on it. I'll try and email it, tell me if you get it.
