Replace the color sensor. 2. After you replace the color sensor, start the computer and run the Sensor Replacement Utility program by clicking Start ➙ All Programs ➙ X-Rite ➙ PANTONE Color Calibrator ➙ Sensor Replacement Utility. 3. If you do not have access to the hard disk drive, provide the customer with information on how to run the Sensor Replacement Utility. • If both the hard disk drive and the color sensor need replacements: 1. Before you replace the color sensor, back up the color sensor calibration profile ECCM2SensorData.dat to an external media device from the directory C:\ProgramData\X-Rite\ECCM-2. This calibration profile is generated after you use the color sensor for the first time. 2. If you are unable to back up the color sensor calibration profile, and if no problem was reported with the color sensor, proceed to replace the color sensor. 3. Replace the hard disk drive. See "1040 Hard disk drive or solid-state drive" on page 60. Then reload the operating system. 76 Hardware Maintenance Manual
