If you just want page #'s and no footer text: create your page break by: Insert, Break, and under Section Breaks, select "Next Page" then from the top of that Page:Insert, Page Number, Format, and under Page Numbering select "start at" and type in "1"

this will also work with a footer, if you make sure that the type of "break" you've created is a "next page" break by using the Insert, Break function (instead of just letting Word automatically create the page break)
