Same thing here...I have a LJ 2430TN that has a "loud" rumbling noise when it prints. Seems to come from the fuser area but all the fuser gears look like new. There is a dusting of powder coating a bunch of "white" gears that appear to drive the fuser gears. I don't have another fuser to swap into this printer..any ideas or information would be greatly appreciated. Thanks .....
