Once all wires and screws have been removed, gently take the motherboard out of the printer.

These wires are soldered onto the bottom of the PCB and must be de-soldered in order to completely detach the motherboard from the printer.

If you do not know how to operate a soldering iron, do not attempt to finish this guide.

De-solder these eight solder joints on the bottom of the motherboard.

When reinstalling the motherboard back into the printer, solder the highlighted joints (in orange markers in the second photo) back onto the board.
