WorkCentre 6515 vertical lines brand new printer

[printeroid]

We've got a brand new 6515 with a solid black line (prints heavy on one side and lighter on the reverse but still quite noticeable). We've also tried checking the various parts but can't see anything obvious. We think it is the LED module. We've tried cleaning it and an inspection but there is nothing visibly wrong with it.

We also have the exact same problem with a brand new machine. Xerox technician changed almost every part of the printer, including drums, transfer belt, print cartridges... this seems to be a mysterious and unsolvable problem...

Any suggestions please?  Should not be happening on a brand new device.

Update: I have performed a clean of the interior as per instructions here: Solved: Re: WorkCentre 6515 error 094-325 - Customer Support Forum (xerox.com)

Still seeing the lines on the page.  Please can anyone help?

I have a brand new WorkCentre and all of my prints have vertical lines.  Is something like this covered by Xerox Warranty?

I have run the Developer & Transfer Roller Cleaning function on the printer, but no change in prints.

I examined the transfer roller (I think?) and it has the same black lines on it.  What is the fix for this if anyone knows?  Surely this should not be happening on a brand new printer?
