My printer is printing a black line on the left side of the paper. Can I clean the roller and make it stop?

Generally, the rollers are replaced when they get dirty, but it would be possible to clean them with a little lighter fluid.
You would really need to remove the rollers to do this - search the web for your printer's maintenance manual. (Failing that, an 'exploded diagram' may assist you.)
