FAQs & Troubleshooting

I received a "Calibration failed" error message when attempting to calibrate my scanner. (For Windows)

This error message appears if the calibration failed. During the calibration process the calibration sheet, with the large black bar facing down, should scan with a back and forth motion and finally move to the input slot.


NOTE: Illustrations shown below are for representation purposes and may differ from your Brother machine.



If after this, the calibration fails more than likely the calibration process was unable to write the calibration data file to specific directory.

This problem can be corrected by the following:
