Application notes Eliminate lead screw drive banding problems. Universal's lead screw assemblies, with lead accuracies to 10 microinches per turn and 25 microinches per inch... can occur on an image, perpendicular to the travel of the lead screw drive, with a spacing equal to the lead of the lead screw. These stripes, simulated in Figure 1, are caused... by nonlinearity of the lead screw thread helix. On an actual output image, the result of banding is a sinusoidal variation in output pixel density, which degrades the image...
