APPLICABLE MODEL:

GESTETNER – 6002/7502

RICOH – 1060/1075

SAVIN – 2560/2575

SUBJECT: FUSING WEB IS WRAPPED PREMATURELY

Target machines:

BCU firmware v3.12, 9-bin Mailbox installed.

1. If SC550 occurs:

Update to v3.14 or later, replace the Fusing Web and reset SP1902-001 to a value of 0.

2. If SC550 does not occur, but firmware is still at v3.12:

Check the value of SP1902-002. If its default has not been changed (60cpm: 18, 75cpm: 15), simply

update to v.314 or later.

If the default has been changed, this means the web has been advanced prematurely at least once, so

check the web itself and estimate the actual percent of web used. Input the estimated % into SP1902-

001, then update to v3.14 or later.

3. If SC500 does not occur, but firmware has already been updated to v3.14 or later:

Since the default for SP1902-002 has been set to its proper value with the firmware update, check the

web itself and input the estimated value into SP1902-001 as described in #2 above.
