Common signs include vertical lines, blurry patches, or light bands, especially if they appear in the same location on every page. Another indicator is repeated paper transport failures, particularly near the heating assembly. If the paper comes out tempered but ink lifts under touch, the pressure roller may have degraded its thermal properties. Over time, the rubber surface of the roller can become brittle, scorched, or polished, which prevents it from exerting consistent force to fuse toner particles securely.
