I have the same problem and have tried all the fixes suggested but to no avail. In fact, if anything, the line on the bottom is getting wider and wetter. I'm at wits end with this thing. Any new info from anyone?

If this problem is on a laser printer there is only one thing causing the issue.
More than likely there is a permanent scratch in the surface of the image drum that goes all the way around the cylinder.
To verify this simply remove the toner cartridge from the unit and turn it over. You should see a small plastic shutter mechanism which is covering the photosensitive drum. Carefully open the cover without touching the drum surface with your fingers as the oils on your skin will damage the drum surface further. If you see a mark in the drum surface, that is your problem and the toner/drum unit will need to be replaced. This most likely was caused by something that was accidentally introduced into the imaging area of the unit. Before putting a new toner/drum cartridge into your printer verify that there are no obstructions like a paperclip or even smaller a staple as this will get caught in the new unit and cause the same problem. This problem is not covered by manufacture warranty and therefore you will need to bit the bullet and buy a new one.
Hope this helps solve your problem. I used to work as a Systems Engineer for Kyocera-Mita a printer and copier manufacturer so I have seen this issue hundreds of times over the past 20 years.

SOURCE: Thick black line on printed page
If the line runs the way that the paper does I.E. vertical on a portrait then it is dirty rollers normally.
If you open the lid and wipe the rollers this shoukd reduce or eliminate the black lines.

A long black line on scanned images is usually caused by a piece of trash on the scanning mechanism.
Look at the scanning arm (the thing that moves when you scan something) and then see if it has any trash on it. If it looks good then you may have a mechanical malfunction in that part.
Let us know hat you find.
