A year on and I've just received my GS645 from Japan. It looks good but, I can't close the door after opening it. I've set the focus to infinity, wound the shutter on, but the Close clasp seems to not want to press down to close the door (on the bottom part of the clasp). I noticed that the T button (timer) is down and might indicate something.
So, I came to this thread to figure out how to fire the shutter without film, but I'm not entirely sure the full instructions after reading through. Can any elaborate?
Thanks!
