• 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
tension roller with alcohol. Then make sure that there is no foreign matter on the 1st
transfer roller surface and then install a new 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
damaged 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.
• Resetting the counter at the replacement
Counter resetting is not possible in the PM support mode because the transfer belt is not a
PM part. Therefore reset the counter in the PM management setting (08-1228-0) after the
transfer belt has been replaced.
