Disassembly

1. Place the printer on its left side, with the bottom facing towards you
   
   Do not place the printer on its back; this is unstable and can damage the feeder
   

2. Loosen the two M3x6 bolts at the front that secure the bottom cover
   Tools: 2.0 mm hex screwdriver
   Tip: The smaller hole in the cover is for the reset button and does not contain a bolt
   
3. Pull the front of the cover towards you, and pull the two tabs of the cover out of the back panel
   Tip: Place the bottom cover and the two bolts aside; make sure to keep the bolts somewhere safe so you do not lose them during the repair process
   
   The connectivity board is the PCB located at the front of the printer
   
4. Press the lip on the Ethernet cable and disconnect the cable from the connectivity board
   Tip: You do not need to open any of the cable clips
   
5. Disconnect the gray ribbon cable from the connectivity board
   
6. Carefully open the two small connectors that hold the display cables
   Tip: Use your nails, tweezers, or a flat-sided screwdriver to push the latch open
   
   Be very careful; these connectors are fragile
   

7. Fully open the connectors and remove the two display cables
   Tools: 2.0 mm hex screwdriver
   
8. Remove the four M3x12 bolts that secure the connectivity board to the bottom panel
   Tools: 2.0 mm hex screwdriver
   
9. Take out the connectivity board assembly
   

Reassembly

1. Align the new connectivity board assembly with the inserts in the bottom panel
   Tip: Don't remove the board from the ESD bag until just before installing it
   
   Ensure the display cables don't get stuck behind the board
   
2. Secure the board to the bottom panel with the four M3x12 bolts
   Tools: Torque screwdriver with hex 2.0 mm bit, 0.5 Nm
   
3. Carefully insert the two display cables to their corresponding connectors
   Note: Small = touch, large = display
   
4. Push the latches fully closed to secure the cables
   Note: Ensure the cables remain fully inserted while closing the connectors
   
5. Connect the Ethernet cable so that it clicks into place
   
6. Connect the ribbon cable to the black connector at the side of the board
   
7. Align the tabs at the back of the bottom cover with the slots in the back panel
   
   Mind all the wires and ensure nothing gets pinched between the cover and the frame
