If you PDF'd a scan without first converting to text it would be larger. On a quick test I just did, a page from a technical journal with text and line drawings scanned at 200 dpi (marginally better than a fax), and PDF'd at 600 dpi, was 278 KB. If I JPG'd the page at 90%, I got 1239 KB. A Publisher page I had with text, boxes, and line drawings from PPT, took only 86 KB at 600 dpi. The Publisher page looked perfect in the PDF while the scanned page had visible artifacts. It took about =BD a minute just to scan the page. = I use OCR (OmniPage Pro 10) all the time for a newsletter we do. The OmniPage software is fairly current state-of-the-art. And unless the original copy is absolutely flawless -- i.e., not a third generation Xerox with broken letters, smeared background, out-of-focus sections, etc., it can be easier to just re-type the copy than go through and edit the OCR version. For instance, much of the input we get comes as faxes, and about 50% of the time I just re-type rather than OCR due to the poor recognition and high error rate. And I hasten to say, that even with perfect (originals) copy, it's still maybe only 98% correct. That translates to a 100% certainty that you'll have to perform edits on every page. As Karl mentioned, attempting to OCR with mixed text and pictures would be absolutely laborious. Omnipage can pick up the indentatations, but then the pictures would have to be separately inserted in an editing program such as Word or Publisher. I would not be up for converting the manuals. At best, scanning and direct conversion to PDF would take a huge amount of time and require lots of disk space. I know I would not be up to it. Charles R.
