Just so there's no confusion: the IMM 1017 form has several copies (it's a carbon copy thingy, the doctor writes on the top copy and it's visible on the bottom ones as well). The top layer he keeps and sends with the medical results. Copy 2 (the second layer) is what you get and send in with your application.
I printed out the checklist and took it with me to the DMP, just to make sure they wouldn't argue with me. On the checklist, it clearly says you need copy 2 of that form.
