What resolution are fax images?
The standard resolution for faxes is 3.85 scan lines/mm (approx. 98 dpi vertically) with 1728 pixels across a standard scan line of 215 mm (approx. 204 dpi horizontally). The optional “fine” resolution is 7.7 scan lines/mm (approx. 196 dpi vertically) with the same horizontal resolution. Many Group III fax machines use non-standard frames to negotiate higher resolutions (typically 300×300 dpi and 400×400 dpi) with other fax machines by the same manufacturer. Two fax machines (or modems) must negotiate a common resolution, page width, and page length before sending each page. The standard requires that all Group III fax machines suppport at least standard resolution and A4 size so that common ground can always be found. Extensions to the Group III standard to support these higher resolutions in a standard way have been proposed. Their current status is not known [Need more information]. [Need more information on resolutions supported by Group IV].
Standard Resolution is 3.85 scan lines/mm (approx. 98 dpi vertically) with 1728 pixels across a standard scan line of 215 mm (approx. 203 dpi horizontally). Fine Resolution is 7.7 scan lines/mm (approx. 196 dpi vertically) with the same horizontal resolution.Superfine Resolution is 15.4 scan lines/mm (approx. 392 dpi vertically) with the same horizontal resolution. Toshiba Ultrafine Resolution is 15.4 scan lines/mm (approx. 392 dpi vertically) with a horizontal resolution of approximately 406 dpi. This is a Toshiba proprietary feature used only between Toshiba fax units with Ultrafine resolution.Two fax machines (or modems) must negotiate a common resolution, page width, and page length before sending each page.

Q.6 Can I take a fax file and edit it? When faxes exchange information, it is done in the form of compressed images (with the exception of BFT). If you wish to edit or otherwise manipulate a received fax file you have two options: • Edit the file us
