if ya check freestuff and the galleries here, you'll see folks are still posting p2-style images with no shadows. the technology has advanced quite a bit faster than the users' skills, apparently. I have that p2 manual as well, but I can't see a serial number in it. I think it was on a card with self-adhesive labels that said "do not discard" in red letters. I looked at the back page - "troubleshooting worksheet". I don't have P7, but I'm guessing that's a thing of the past.
