      change the drum, I have tried cleaning the unit up etc but in the past it has not really worked the only effective way that I know of getting rid of this is change the drum unit parts.

                  You'll have to rebuild the PCU and replace the developer now you've been messing with the TD initial settings.
                  It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.

                  Hit it.
