Not sure this is what your needing but ,,
The Edge Erase default setting is No Erase, which enables the copies to print within 2 mm of each page edge. This is normally sufficient to remove shadows from the edges. If the dark edge is closer than 2 mm, you must set Edge Erase at Variable Erase.
The Variable Erase option enables the copier / printer to vary the amount of erasure from 0 to 50 mm in 1 mm increments. The same amount of erasure is applied to both top and bottom edges or right and left edges of the document.

There are several issues that will cause a problem like that.
1, As X box mentioned is a problem with the drum. That is part of what is called the print cartridge or imaging unit. There is most likely a shutter or opening in the cartridge which you can shine a flash light at and see if the defect is visible. If so you will have to replace that cartridge. I would suspect that is the most likely issue.
2. There may be something in the paper path. A small piece of paper riped off in it, something else, a piece of tape, label, etc may have made it into the machine, that will make contact with the paper and smear the image.
3. Lastly, your fuser roller may be bad causing the reprint.
How to determine where the issue is, shut the machine off while it is printing and jam the paper in the image area. See if the defect is on the paper before the fuser. Eliminates the fuser ....

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....).
