    Sounds like the developer clutch needs to be replaced. Pretty common, clutch doesn't release and the developer gets depleted in no time. Part #AX200273

      +1 on that.
      Check for diagonal bands in solid areas and if dev unit feels very light, definately faulty clutch

        Yup, we have those clutches go bad on older machines all the time. Put a new black DV unit when you replace the clutch as well.
