Very loud fuser drive noise. Repaired fuser and changed fuser drive gear 8H30-8 which is in direct engagement with fuser unit . Teeth were worn down. Ran machine and still noise but not nearly as bad. Fuser was free. Removed fuser and turned green handle while holding new drive gear. There is still a drive issue from fuser drive unit in rear of machine.
Customer was upset that I had not diagnosed problem on fuser drive unit and chased me out. Did not get a chance to remove rear cover and open system case to access fuser drive unit. Does one or more of those gears get damaged along with the gear I changed.
I am arranging with customer to go back and complete job and would like any assistance anyone has to offer regarding this problem. i think I am on right track but would like some input from someone with experience on this. Your help is appreciated very much. I have not been paid anything yet and already have an investment in parts and time.Frank
