• Handling precautions
- Do not touch the front and rear surfaces of the transfer belt surface with bare hands.
- Prevent oil or other foreign matter from adhering to both surfaces of the transfer belt.
- Do not apply external pressure that might scratch the transfer belt.
- When replacing the belt and transfer belt cleaning unit, apply patting powder sufficiently
and evenly. Otherwise, it may reduce the cleaning efficiency.
- When replacing the transfer belt, clean the drive roller, 2nd transfer facing roller, and ten-
sion roller with a solvent such as alcohol, and then attach the transfer belt.
• Cleaning procedure
Fully clean up the toner and such adhering to the roller with alcohol, and then wipe it with a
dry cloth until no trace remains. Take care not to have the transfer belt surface being dam-
aged or dented. Replace the transfer belt with a new one regardless of the number of output
pages, if any crack or major scar is found.
