Are you setting the correct media type for your media?
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.

There are a number of defects in these images. Can you please mark which defect you are concerned about, and which direct that the paper fed? =^..^=

swap corona units and see if it follows them since a drum swap did nothing right?

Thanks for marking up the images. So the defects are crossfeed? Does it affect CMY images also? Does the defect change?
I think that I would start with the black drum. We've had new drum units in which the rear drum bore is milled to small, so the drum does not insert properly when you slide the drawer shut. To test out this hypothesis, remove the transfer belt assy, and all the drums and developing units, then insert just that single drum unit into it's spot. Then slowly slide the imaging drawer in to confirm that it closes smoothly, all the way, so the front frames touch. Lubrication does not seem to help this issue. I used a rat-tail file to open up the rear bore, just enough to allow the drum to fully insert.
The black developing unit could be difficult to turn also. I've also had the transfer belt unit bearings seize up at high count. =^..^=

If only the black is doing this
To test and see if the black dev unit is problem you and swap the black and one of the color dev units (ex. Cyan). Just be sure to put scotch tape over the hole where toner goes in to the developer unit on each unit. Then boot straight into service mode and run 1 cyan test chart at 128 density it will come out black because of swap. if it still has bans then you have a bad black developer unit. Only run 1 print to test if you run a lot it will make a mess due to toner trying to add.
if you leave the toner door open it wont try to add toner during testing like described above.
