Explanation
Printers use optical or mechanical sensors to detect the presence and position of paper as it moves through the paper path. If a sensor is dirty, damaged, or defective, it can falsely report a paper jam even when no paper is present. This is a classic 'ghost jam' scenario. Defective rollers would cause actual physical jams or misfeeds, not phantom error messages. A defective power adapter would cause power issues, not jam errors. Defective print cartridges affect print quality but would not trigger paper jam sensors.
