notaguru - what software are you using to do the scanning, I'm not an expert but my understanding is that the better scanning software will remove the page numbers as part of the scanning process - Abby FineReader is most often mentioned as being the best.
And if you have existing skills with a word processor such as Word or Writer, then perhaps you should consider 'fixing' the bulk of the errors that result from scanning in the word processor - there are a number of alternatives for converting the word processing format to EPUB.
