If I've cleared the paper jam, why does the P2 error keep returning?

If the error persists after clearing the jam, there might be a more serious issue with the paper feed rollers. These rollers may be worn, dirty, or damaged, preventing proper paper feeding. Cleaning the rollers with a damp, lint-free cloth (isopropyl alcohol can be used for stubborn residue) might help. If the rollers are visibly damaged, they may need to be replaced.
