The photocopied pages from Sony are pretty awful, folks. The scans I posted are probably the best compromise of image size and quality -- these are not done from an original, and all I would get by bumping up the resolution is slightly better contrast, but it would still be a low-quality picture.
When I print the downloaded files, I get a very readable print.
I use a Visioneer 8800 and PaperPort to scan, and after doing some cleanup I usually export as an uncompressed TIF. Then I do conversion and resizing within ACDSee. Frankly, the issue about file types is one of more in which the recipient is more a problem than the sender. Unless the recipient has image-manipulation software, or a photoeditor, they can't see the picture in most of those file formats, so I usually share web-posted images in .jpg format, which is small enough for most people to deal with even with slow connections and only a web browser. Lowest-common denominator, perhaps, but that is what usually works.
I can convert to .pdf only by using Corel WordPerfect, which means embedding the image in another file, and there's no file size or image quality savings when doing this conversion. TIF files work best there, but the image size is huge.
And faxing? You have to be kidding, esp. with the copy I have to work with! The image quality for a fax is probably the worst, too. And I would have to do it myself, and honestly, I can't spare the time at work to do real-time faxes to so many people.
Sorry.
