If she poops somewhere other than on the pad pick up the poop and put it on the pad, leave it there and let her sniff and get used to it being there. do the same if she pees, before you clean up the pee try to soak a some of it up with the pad, then leave the pad down for awhile. Be sure to clean the spot on the floor well with a good cleaner so she won't go back to that spot again.

If you use newspaper I'd suggest putting a pee pad under it. Newspaper isn't too absorbent and it may leak through. The ink on the newspaper (especially when wet) may stain the floor. You could also get a pee pad holder to keep under the newspaper.
