Sharp mx-5071 leaving black lines

[driving lots of miles]

I have a sharp mx5071 leaving black lines on the pages, internal prints copies and print from computer. When I run a full color drum shadowing page (thanks Blackcat) only the black page show the lines. I have replaced the black drum unit twice with rebuilt units. I have swapped out the fuser as it looks like it is ghosting. I have also tried a different transfer belt and replaced the developer. We are using genuine Sharp supplies. I have cleaned all the connection points for the black units. I am not sure where to go from here. Any ideas are welcome.

I have read and re-read this post and I am still going to ask the question. Did you replace/swap the main charge?
You probably did, but I must ask.

Both drum units i tried had been rebuilt with new drums and charge units.
