Embodiments of features for a paper punch machine are shown and described. Preferably, these features, which may be called "accessories" whether they are built-in original equipment manufacture or retrofit equipment, assist in proper paper alignment and punch control. A first accessory is an improved paper stop that is both grossly-adjustable and finely-adjustable, by a preferred combination of a biased sliding mechanism, followed by a fine-tuning mechanism gradually laterally moving the paper stop by causing a threaded shaft to rotate after the paper stop is already in the preferred "gross-adjustment" position. This way, the paper stop is brought close to the proper marking on the housing appropriate for a particular paper or die assembly, and then exact adjustment may be made in very small and precise amounts. If desired, the user may record or remember how may turns of the threaded shaft are typically required for a particular fine-tuning job, because the threads on the threaded shaft represent quantifiable and reproducible adjustments.
