In addition to loosening the takeup tension, when you thread make it a point to manually advance the projector by hand until the take up reel "catches" the film tightly instead of just threading it at the point where you would start. This can save an awful lot of startup bounce as well, but concentrate first on that takeup tension.On that RoundThane belt, it shouldn't be fitted too tightly, but not loose enough that it can't jump the pulleys either. Also, please refrain from using "teaser" subject headers in the future. This is in the FAQ and makes surfing the forums and searching the archives difficult.

In addition to inching the machine forward, I found that giving the reel a little gentle push on startup was very helpful. It is possible that the reel is slow starting, then builds up enough inertia to jerk and lose the loop. Gordon is right on the money about that. However, the the motors on the 9030's and 9050's ramp up slowly, and I don't think the resistor is really needed. Although the loop can easily be restored "on the run", it is still an inconvenience. It would also suggest that the holdback sprocket may be worn out, and/or the pad roller is grossly mis-adjusted.
