Viday, loosen the two tiny screws that hold the lens assembly and adjust it. The pressure plate may be too tight against the aperture. Also, you may have new style leader attached to your films. Many ST 1200 have a difficult time allowing mylar or other newer film stock to get past the lens stage of the projector.

Thanks, but it's happening way before the aperture/gates. It's when the film touches the sprocket wheel and don't follow the path, just grinds directly onto it.

Vidar, I had the same problem with my Beaulieu until I was told it accepts only films that have been cut with the Beaulieu cutter on the projector. Maybe it's a different problem with your projector but it worths trying. You may also try to set the speed at 18 fps when threading.

If you say this happens before it gets to the lens area, it can only be two things: the upper sprocket isn't dead center. Someone may have taken it off and when it was put back on, it's oblong when it spins. The other could be the short film guide/path isn't aligned with the sprocket. It's nothing major.
