FIELD COUNTERMEASURE:
If the BCU firmware is version 3.12 at machine installation, update it to version 3.14 or higher before
installing the 9-bin mailbox.
For machines with the 9-bin mailbox already installed, SC550 (Fusing Web End) may appear if updating the
BCU firmware from version 3.12 to version 3.14 or higher. If it does, perform the following:
1. Update the BCU firmware to version 3.14 or higher.
2. Replace the fusing web if it has physically reached its end.
3. Set SP1902-001 to a value of "0".
4. Check the value of SP1902-002. It should be "18" (B064 models) or "15" (B065 models). If the value has
been changed, input the correct value listed above for the appropriate model.
5. Check machine operation to ensure that the symptom does not occur.
