1. When removing the "paper jam", only move the parts that are allowed to move in the copier manual.
2. Take out the whole paper at once as much as possible, and be careful not to leave broken pieces of paper in the machine.
3. Do not touch the photosensitive drum to avoid scratching the drum.
4. If you are sure that all "paper jams" have been cleared, but the "paper jam" signal still does not disappear, you can close the front cover again, or turn the machine power on and off.
