The problem persists.Y NReturn to Service Call Procedures.Verify the connections and condition of the circuit between Xero CRUM and MCU PWB. Thecir-cuit is free of damage and the connections are good.Y NRepair the damage as required.Check CRUM operating voltage. The operating voltage is correct.Y NCheck the circuit for damage. If the circuit is free of damage replace the MCU PWB (PL9.1).Enter diagnostics and verify NVM value for Xero CRUM data, location [751-010]. If NVM value indi-cates failure replace Xerographics Drum Module (PL 4.1) If NVM value indicates no failure,replace the MCU PWB (PL 9.1).091-915 Xero CRUM Data RAPBSD-ON:9.1The Control Logic detected incorrect data on the Xero CRUM.Initial ActionsCheck NVM location 740-047, for Geographic area:• NA/EU = 3• DMO-E/W = 12• All the World = 512Check NVM location 740-049, for Contact Type:• Metered = 3• Sold = 2• Neutral = 31ProcedurePull out and reinstall the Xerographics Drum Module.
