Does your feeder have a plastic insert that goes underneath the tape, its only removed for thick parts.  Looks like Neoden has 2 versions of the feeders,  the newer ones don't come with the plastic insert possbily, not 100% sure.

My Quad feeders have a "spring" under the component tape that presses the tape up against the upper part of the tape track in the feeder.  I never really thought about it, but it now becomes obvious that the purpose of this spring is to keep the tape from being deflected by the nozzle or sprocket pins.  The spring is a flat strip of springy steel that is a bit narrower than the component tape.  The tape pushes the spring downward, and it accommodates the thickness of the tape.  The Quad feeders have the sprocket behind the pickup location of the tape, so it pushes the tape toward the pickup point.  That may also help prevent the tape from bouncing as the teeth pull out of the holes.
