Although the problem sounds like a defective CCD, which is not repairable, I would strongly suggest you take the unit back apart and clean it again.
Why?
Because one
single speck of dust on the mirrors will cause a vertical line like the one you speak of.
Here is a trick I use to clean the optics on copiers:
1) Get a low lint rag or shop towel NOT a paper towel, tissue, etc
2) Get a bottle of Windex. The stuff with ammonia works better on optics.
3) Spray the Windex on a corner of the rag. Make sure it is very damp.
4) Clean the mirrors/optics horizontally from side-to-side, making sure to get the corners.
5) Use the dry portion of your rag to soak up any residue. Once again, go side to side, not up and down.
6) Shine a flashlight on the optics and make sure there is not a single smudge or speck of dust. If there is, go back to step 4.
Also make sure to clean both sides of the glass.
Good luck! If my answer helped you, please rate me and comment. If not, please follow up with me. Thanks!

- Oh, I forgot to mention that there is no electronic calibration or adjustment. Obtaining an image, whether it is a copier, scanner, or similar, is a purely physical process. If there is a line, there is something obstructing the view of the CCD. Somewhere.
Also, if the CCD is visible, clean it as well. It looks like a thick cylindrical lens or flashlight thingy. It is kinda hard to describe, but you will know when you find it.
Good luck!
