I agree with the two previous posters. Arcing between the primary charge unit and the drum will cause the void dots in the drum surface. It makes sense to replace the primary charge unit once in a while, to prevent damaging a $2K drum. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Drums already pitted
replace it and the coronna units
time for maintenance a canon tech would have done this already

I was having this discussion with another tech just the other day. Sometimes no matter how well you maintain it, those drums just get pitted. Just bite the bullet and put in a new drum + corona assy's.
If you have an account that doesn't care about the white dots in solid areas, you can leave the wires in for 1 mil (I never tried but he said it can be done). But if you really want to minimize the pitting, just do the routine maintenance. Don't let the wires go more than 250k, replace the blue cleaner pads with the wires, and replace the entire corona assembly every 1 million copies. And don't forget the ozone filter. Anyone who worked on the NP6650 will knows heat + coronas = pepper marks. Remember shimming the primary fan duct?Comment
