    • Lift up the back cover to remove it.

    • You may need to lift firmly as it requires quite a bit of force.

    "quite a bit of force" is almost an understatement, I found 2 clips along the bottom of that rear piece, one at the far left one around the middle (indicated by an arrow on the underside of the machine) - undoing these required much persistence with a screwdriver

    Perhaps Fuzz -

    • 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.

Abschluss

Congratulations on successfully removing the motherboard from the printer! To reassemble the motherboard, follow these instructions in reverse order.
