That's really odd, it should be doing it on all three unless there are multiple issues.
Are the line's horizontal or vertical (when the paper is portrait, not landscape)?
Are they in the same spot every time?
When you copy is there more than one line?
When you print is there more than one line?
When you scan is there more than one line?

While I wait for your response I'll post the most likely cause:
Lift the lid. Now lift the document feeder lid, it opens to the left. You'll see the feeder mech, you want to lift that to the left as well, it will raise 2 inches or so. See that section of glass underneather it? Clean it. Really good.
Then you see the white piece of plastic above the glass, clean that really good too.
If it's a perfectly vertical line it's probably caused by some dirt in there, what happens is the scanner bulb sits in one place, the paper is then dragged over the same spot. If there's a speck of dust there, it covers the whole page, top to bottom. You clean the white piece because there could be dirt on there, then when the bulb shines through the paper, it's reflecting back as a dark spot.

Only when I use the feeder. I lifted up all of the covers and cleaned the entire glass with a soft dry cloth and it still makes the line.

If it's only the feeder then there is definitely something there. Might not be something you are able to get (might be dust trapped under the glass, or a nick in the glass.
