.tiff files are usually extremely large and the large size of the file could be causing the problem. Why not scan the file as a pdf, which should work fine for regular documents, and then FAX the page normally? I've got an EPSON XP-830 and it seems workable here but this printer has FAX ability also.
Hope this helps.
I'm using an Epson XP-610 combination printer/scanner.
When copying a document in ( Print image matching II tiff )
which is the only tiff setting that will allow me to fax using windows fax and scan I end up getting two copies of the document one standard size and one compacted and condensed size not suited to be faxed. What am I doing wrong? I end up faxing twice the amount of pages needed
and if I scan in tiff only the fax only sends blank pages...
