I'm recently getting little smudgy black lines of varying width on the edge of my paper. it looks like a dirty roller or something is putting down a little pattern. this only seems to happen when I print an image that's got a lot of white and it's not all the time. I'm assuming that my ipf8300 needs some sort of cleaning but I'm not sure where/how and I don't seem to be putting the right terms into google. can anyone lend a hand?
