Explanation

Vertical lines on a laser printer output are a classic symptom of a damaged or scratched photosensitive drum (C). The drum is the cylinder that holds the electrostatic image; a physical scratch or coating defect on the drum creates a consistent mark in the same position on every page, producing a vertical line. A bad fuser causes smearing or unfused toner. Toner cartridge issues typically cause faded or speckled prints. A faulty mirror would cause the entire image to be distorted or missing, not a narrow vertical line.
