Tips

Always power off and unplug the printer before installation. Allow the fuser area to cool completely to avoid burns. For best results, replace the pressure roller as part of a full fuser maintenance kit if other components show wear. Keep a spare roller on hand to minimize downtime in high-volume printing environments.
