- Streaks or lines on printed pages: This is a common sign of a failing fuser unit. The toner isn’t properly bonding to the paper, resulting in uneven printing.
- Paper jams: A worn-out fuser unit can cause paper jams as it struggles to feed paper through the printer.
- Smeared or blurry prints: If the toner isn’t fusing correctly, the prints might appear smeared or blurry.
- Burning smell: A burnt smell coming from the printer is a clear indication of a failing fuser unit.
- Error messages: Your printer might display error messages related to the fuser unit, such as “Fuser Unit Error” or “Fuser Unit Failure.”
If you experience any of these issues, it’s time to consider replacing the fuser unit.
