I had always thought that faxes were a big no-no for character recognition software? I know that we can't use it for one of our OCR solutions because it is just too... well, crappy. The image quality is nowhere near what it should be for a successful OCR pass. As for client expectations: hell yes--tell them not to use a fax machine in the digital age. Scan the document and e-mail it or something. Where I work, we've done away with 90% of any fax machine usage in order to have documents that can be used by our OCR solution.
