If you're still getting smudges, there must still be a label or part of a label either on one of the image drums or the transfer belt, i've found in the past it somethings gets stuck inside the unit on the cleaning blade. What i suggest is you run a print and open the front door at the paper travels along the transfer belt, look at all the image drums and see if you can see the smudge on one of them, if so the problem is caused by that cartridge if not it's in the transfer belt somewhere. You may need to try stopping the printer a few times and if the problem is in one of the cartridges, you will mst likely have to replace it, as with the transfer belt if you think that's causing the problem it's easier to remove it and rotate the belt manually.
Please note the image drums and the transfer belt are all light sensative

Are you sure this is a Designjet 450 (large format printer) and not a Deskjet 450 (portable printer)? The following assumes you have wispy black streaking on the printed side of the paper. If the streaking is on the back side then post more details of the printer model and the issue.
In either case the most likely cause is a buildup of fibers on the underside of the printheads or carriage, causing wisps of black ink to be dragged on the paper when the carriage reverses direction. You can clean the printer as shown at the following (though the details will be somewhat different for the Designjet or Deskjet....).

Your problem is due to a worn fuser unit (upper fuser roller).
The teflon coating has worn again, alowing the toner to stick to the roller and then "repeat" about 3x down the paper (getting fainter each time).
You need to order a new fuser unit.

Make sure you order the currect voltage (US or UK)

Very nice trouble shooting. The image defect you describe point to the OPC or drum unit this is essentially the toner cart. In your case black. Measureing the distance between repetitive defects is a sure way of diagnosing problems such as yours. Again nice work.
Google repetitive defect ruler for your model to help in the future.
Hope this helps
