Sometimes called "neutralizing the Geneva" which refers to the internal mechanism in projectors that use a Geneva drive. Making sure your intermittent is both centered (we'll go over how to do that in the framing mechanism section) and in a neutral position in relation to the [[Geneva mechanism]] is a must before starting any show. Neutralizing the intermittent must be done before threading a projector EVERY SINGLE TIME no matter what, regardless of whether or not your framing has been re-adjusted. | Sometimes called "neutralizing the Geneva" which refers to the internal mechanism in projectors that use a Geneva drive.

*To place it in a neutral position, place your fingers on the intermittent sprocket and advance manually. The intermittent sprocket does not rotate continuously, but in steps. Once it's completed a full rotation and stopped, it will be in a neutral position. You should be able to rock the manual advance back and forth a little bit with the intermittent sprocket remaining still. | *To place it in a neutral position, place your fingers on the intermittent sprocket and advance manually.

If you find that the intermittent sprocket moves slightly while it is in the dwell state (so not during pull-down) that's a good sign that your intermittent is in need of repair. Any movement during the dwell state can result in jitter on screen. | ||
