If It runs top to bottom, in a perfect line straight down the page, on every page you print its something on the roller inside the printer.
did you have a paper jam and have to tear paper not long ago?
Maybe a staple of something small..
your should be able to open the cover, remove the toner drum and look straight at the roller.... be careful try NOT to touch it... there will probably
be a flap, spring loaded flap that you can open with your fingers.
