Let's start by removing the plastic cover on the Pentagraph, please remove these screws circled in red:
Left side:
Right side:
Back:
Turn the machine OFF, and we'll be moving the pentagraph manually. We want to make sure that the Metal Piece is going to the sensor Black Slit on the sensor like so (Yours might look a bit different):
Please send us pictures if you are not sure. If your sensor looks like it's correctly placed, we'll need to clean the black piece of the sensor with some Compressed Air or Isopropyl Alcohol 70%+.
