Explanation
In a laser printer, the photosensitive drum is the component responsible for forming the entire image on a page from top to bottom. When the drum is dirty, scratched, or has toner buildup, it produces a consistent defect that repeats or spans the full length of every printed page as the drum rotates - manifesting as thin vertical lines. Performing the drum-cleaning procedure (or replacing the drum unit) addresses the root hardware cause. Replacing paper (A) has no effect on a drum defect. Clearing the print spooler (B) or reinstalling the driver (C) are software fixes that cannot resolve a physical drum contamination issue.
