Some films thread fine. Others stop at the rear sprocket causing bunching.

What might be the cause?

Appreciate any input, people.

Michael...In my experiences with mine you must have the film trimmer on the machine do the trim on your leader or it will get caught up in the second sprocket.

That's my input! [Smile]

Hi Bill,

Yes I always do this but still some prints are getting caught.

The trimmer would have been my guess too.

After that maybe it's some difference in the thickness/stiffness of the leader?

All I ask is a wide screen and a projector to light her by...

Make sure the film has the correct curl. When dangling from the feed reel it should curl slightly towards the projector and not be straight down or away from the projector.
