you might want to check the transferbelt, its a large, shiny black belt that sits under the toner.  if you remove the cartridges you'll see it.  shine a light in there and see if that belt is contaminated by yellow toner.  if so, you'd probably have to replace the belt.  you can also try running a cleaning routine by accessing the maintenance/troubleshoot
