Repetitive defect distances are precise Mike.
So 94mm is not close enough, ity is important to measure to the nearest 1mm.

Neither do I, but the only roller that has a diameter similar to that of the 
drum will be the fuser.
I agree that replacing the fuser is probably not sensible. Also fuser defects 
in this printer tend to be on the back of the paper.
Sory that's all I can offer.
