    You said you replaced the DV unit and worked for a day and problem returned.
    Sounds like you may have contaminated toner or a bad toner sensor.
    You may need to clean out the toner hopper (make sure the bottom transport coil has no damage), replace the DV (and make sure it calibrates properly) if not replace the toner sensor as well. If it is bad, it could be overtoning causing the background. Also make sure to use OEM toner.
    ** don't use your vacuum on the DV unit with the toner sensor still on it.

        one more thing is the drum counter
