Pagis / Xerox xif file conversion

XIF file conversion
After using Pagis or scansoft for years I have hundreds of xif files. The documentation for XnView and Nconvert indicate that these files can be read and converted. When attempting this I receive the following error: TIFF: Bad data compression algorithm! ... this occurs for both XnView and Nconvert. Any ideas?

Only some Xif can be loaded
