Remove the Print Head

  1. Completely unload any print material from your printer.
  2. Power off your printer.

  3. Slide the black FFC Clip away from the metal bracket and onto the cable.Markforged FCC clip

  5. Slowly and carefully remove the connector from the print head. 
  6. While supporting the print head with your hand, use a 2.5mm hex key to remove the two screws connecting the print head to the print head base.

    Note: The photos above show an Industrial print head. The Desktop printers have a different print head, but the removal process is the same.
  7. Carefully pull the print head off of the print head base.
