If you do not have a spare board to fix the scanner or you just want to make sure that a new Main Board will fix the issue, you can Temporary use a Main Board
from another HD Ultra scanner without changing model or serial number.
However, you will have to complete the repair with a "Spare Part" Main Board and go through the Activation Wizard.
Problem with Activation
If the wrong License key has been merged with a new scanner you will have to contact Support to solve the problem.
