I've used the maintenance functions to clean the fixing assembly, ITB & feeder. It helped slightly, but I still have toner streaking down the middle of my pages. I checked toner levels. Yellow is at 70% and magenta is at 60%. (These are the only ones streaking. Everything prints fine, but then I have these streaks. I'm not sure what else to do to improve quality. Any suggestions are appreciated! See image for greater clarity.
