The first thing to check would be the gate tension being too weak. If turning the adjustments doesn't help, then the gate tension bands (or shoes) are worn and should be replaced. Also, you should check the side film guide rails to see if a groove has worn into the metal. If so, that should be replaced.

What make and model projectors are you referring to?
