This problem is created by the program that you are using to create the file to be faxes. When a
document is created you must make sure to output the document in landscape mode if the document is to be output as landscape or portrait mode if it is to be output as portrait. Please make sure to confirm the correct orientation before
creating your document.
If you are still having problems, try creating your document in landscape mode and then a second document in portrait mode. Then try faxing both to yourself to see which one works.
