Check the IU yellow, or try to replace the IU /Y

Yellow developer probably crashed. Pull yellow dev unit and see if a lot of the developer is gone. This usually happens when a drum is way over life and starts to short out. You will have to replace the yellow developer unit & drum(s). Keep in mind if you don't change any drums that are over life you may crash the new developer. Color developer units are $400+ each so you want to be sure you fix the cause!
