OK, a lot of us have fought this. I may have found something that may help. Everything else hasn't changed a thing.
A little background; this customer tried a 6000, and it had enough service calls for light black that we tried a new machine and came up with the same result. Developer replaced about twice a month.
While on the last call, I noticed that vT was extremely high (4 volts). I looked at vtref and it was set at 3.9. Prints were extremely light. (I checked another 7500 later that day, and found vtref at 1.89.) I then found that this machine will adjust vtref on the fly. I thought vt was fixed when you init'ed the dev. I also found an sp where you can turn off this vtref adjustment (sp3042). I set this to off, and ran the crap out of it, and vtref stayed put. Machine now has fresh dev, vt about 2 volts, and I will post updates as to whether or not it worked.
