Help! Is this a bad fuser? Or what?

[GoodMew]

Hello, I need to identify the issue with this Xerox Phaser 7500DT. About 1/4 of the top of every page is very faded and blotchy, which is particularly noticeable on solid color fills. Also about 1 inch at the bottom of solid color pages is faded. This is on every color, every print. I have run all tests and calibrations for color and paper. I have gone through all of the cleaning and maintenance steps. At this point, it must be a failing component.

I just need confirmation on if this looks like a bad fuser, or imaging unit, or a combination of things?
