I've recently been getting black streaks on the left side of my paper when I print with the Xerox 6280. There's no real pattern to the streak. Sometimes there are several that are close to each other and other times, each streak is far apart. I've changed the toners that were low and the fuser since it needed to be changed soon anyway but it did not correct the issue. I also made sure the paper type was correct. Any suggestions of what the issue might be and what can be done? Thank you in advance!
