I've seen this a few times now. I have/had several 8060s that would have dots etched into the drums. It almost seems to me like there was arcing between the main charge and the drum. Well, at least that's the best reason I can come up with for what causes it. I seem to find it on machines that have F6-17 set really low (like -30). I don't have many of them left out there but the one in our shop did it to a new drum that had less than 10k on it and I don't want to see this happen again. It may also have to do with us using compatible drums but I can't say for sure. Anyone have any thoughts on this? Thanks in advance!
