- We solved the problem. It turns out that Migraph OCR likes the
- IFF files created from the faxes just fine if we use the "detail"
- or "fine" setting on the FAX machine at work. There _was_ some
- very tiny print that OCR couldn't cope with very well, but aside
- from that, it worked amazingly well. 'Course I've never seen any
- other OCR program in operation ;-{).
