Hi all, Just purchased a Polaroid SX-70. Looks to be in good condition. I loaded brand new pack of film and the camera ejected the darkslide as expected. Then went take a photo and there is a nice shutter clicking noise and the camera appears to try and eject the first photo (you can hear the beginning of the whirry eject noise and see the rollers start to turn briefly, but the film does not eject. In fact, the film does not move at all. Then if you remove the pack and re-insert it (at this stage the camera thinks it is a new pack of film), the photo is ejected (the camera thinks it is the darkslide). Then the same thing happens again - go to take a photo, the shutter sounds good and it makes a whirry noise for half a second or so, but nothing ejects. At this stage the camera is "locked up" - can't see through viewfinder and can't take another photo. In fact there is something mechanical preventing you from fully closing the case (it won't latch into the flat position). Then if you remove and re-insert the film pack, the top photo is ejected and everything is reset. Then when you click the shutter release the same things happen again... Someone else has the same problem and has a youtube video of it: https://www.youtube.com/watch?v=JCS8U7oKkfY Any ideas?
