BizHub C6501 Heavy Banding Issues

[jsesic]

So I have a C6501 without any sort of maintenance contract, long story. The problem is my prints are getting very heavy banding/striping (see attached).

I have about 275,000 copies run through the machine.

Recently replaced the coronas myself.

I am just trying to figure out what is the most likely reason behind the banding so I can hire someone to do the targeted work. I am guessing it is the transfer belt? But any more skilled, experienced advise would be so greatly appreciated.

Has it had a service of any sort? At that volume you're looking at a full service. That's 4 drums the devs and the pm kit... If you've got to that sort of volume without quality problems you've done very well!
