There was a firmware change for this model to improve fuser cleaning to reduce the amount of toner droppings: BICU firmware v2.11bs. See if that's installed and that the recommended setting change of SP 3-905-002 (Job end cleaning frequency) is at 5. That should help with this issue. I have had a couple LD135s with similar issues that needed a few extra zeroes and ones to fix the toner goobie problem.
Overall on these fusers I use a mix of old and new parts to make them last longer. Heat tube and press roller are the only original parts I use. For the cleaning roller I use the old AE042029 as it just seems to collect better than the treated surface on the newer cleaner. Since the main culprit for the heat tube wearing is thermistor scars, I use the newer AW100111 and AW100112 thermistors. They have a smaller surface which makes it more difficult for toner to build up on them. Your fusers will thank you for these mods.
