It looks to me that the fuser needs replaced.

Print a A3 report from user menu (open any other A4 trays) and stop the sheet half way through the engine.Part of A3 just about fuser and the rest below drum and you'll see where the issue is coming from.

I suspect drum, but thats me.

I vote for the DV unit...We could stop the guessing by simply measuring the distance between the repeating dark bands and checking the repetitive defect guide.

check and re-install the charge roller. clean debris from charge roller cleaning brush.
check and re-install the drum, inspect drum grounding contact. apply conductive grease to the drum rod pointy-end.
reset developer bias to default values?
Those are my first guesses.

There might be helpful information in the distance between repetitive marks on the page(mm)

Dev and MC been replaced as per poster of the problem. Question is whether the parts were new and what calibrations have been processed and whether the toner is OEM is another question.
Let's wait and see.

Sorry my bad...The Dv roller needs to be checked to verify if the DV is new...The Dv must have it's full black coating...Also excellent point about the toner...

But then checking the repetitive defect guide would point to the offending unit.

I'm with sparkycivic on this one. If the interval is 37.5mm it's primary charge. =^..^=

I had this exact same issue on a 4501i last week and it resolved with a new DV unit.

That definitely looks like it's coming from the mag roller in the developer unit, although you said you changed it. Next, I would check the mc like you did. I'm curious how many clicks are on the fuser? I do believe the life of it is 300,000 under warranty I believe.
