- Do not apply external pressure that might scratch the transfer belt.
- When replacing the belt and transfer belt cleaning unit, apply patting powder sufficiently

- When replacing the transfer belt, clean the drive roller, 2nd transfer facing roller, and
tension roller with a solvent such as alcohol, and then attach the transfer belt.
