Hey guys I've recently put up a post regarding ink lines etc with my rs-640. Well I've just changed the ink lines, cap tops and dampers on the machine and it's up and firing. But when I leave it on it switches off to sleep mode as it always has but now it has been turning itself on and has the now processing screen and stays on that and you can't shut it off. Any ideas on what I may have done to cause this? I've shut it off for a few hours to see if it would sort itself out but no good. Any help would be greatly appreciated. Cheers
