I thought the instructions generally say no scans/copies? Only print-outs from the site or actual forms from figures. I could be wrong on that. Check and old one though, to see what the rule regulations are to be sure though. That'd be my advice.
Same with when you send in... If it says, "Post marked between X & Y", then the rules are pretty clear. If it just says postmarked by Y though, you're probably good to go sending them in immediately.
