As with all Simplex and RCA soundheads, one source of potential film damage is the rubber roller (Simplex part G-1985) on the lateral guide roller, which makes contact with the picture area. This roller can accumulate dirt, and can develop a flat spot if left closed when not in use. '''Always leave the lateral guide roller open when not in use.''' When worn or dirty, it can leave a wear pattern on the surface of the film. One workaround in the platter era was to remove this rubber roller and replace it with a spacer. This is an option for platter or large-reel playback, but is not an option for reel-to-reel projection because it takes too long to get the sound drum up to speed with this modification. | As with all Simplex and RCA soundheads, one source of potential film damage is the rubber roller (Simplex part G-1985) on the lateral guide roller, which makes contact with the picture area.
