    Delete Calibration.dat file in C:\Program Files\Brother directory, and re-calibrate. It will work.

    Warning: This tip has not been tested. If you choose to try it then I suggest saving the Calibration.dat file as Calibration.dat.old instead of deleting. That way you can restore it if re-calibration doesn’t work.
    Thank you for the tip ch kim!

    You have to disassemble the scanner and reseat the ribbon cable from the glass housing to the main board. Done it hundreds of times and it worked every time.
