+[* black] The print assembly is still secured to the base on the right hand side (I haven't quite worked out how to release it). This doesn't matter if you want to remove the main logic board.
+[* black] Lift the left hand end of the print mechanism. This will provide sufficient room to slide out the main logic board towards the front of the printer.
+[* black] Examine the main logic board for signs of overheating. Also look for any electrolytic capacitors with domed tops, indicating that they are failing.
+[* black] There have been reports that some of these printers use electrolytic capacitors of poor quality, bearing the name TEAPO and having a green and gold sleeve. Pay special attention to any of these.
+[* black] Care is required in remving and replacing any suspect or failed components as the tracks on the circuit board are very fine.
