When you create the Heading section (your name and contact information) on your resume, don't use the header function of your document. Why? When the employer opens the document on his computer, your name and contact information will be greyed out. Your name is the most important information on your resume! You want it to be high contrast (black on white) so it will stand out.
The solution is to write your Heading in the body of the document (don't use the header function at all.) By the way, it's perfectly fine to use the footer function for page numbers (for example "page one of one" or "1 of 2").
