When this error appears it means that the print head and electronics cannot communicate (properly) with each other. This is most likely due to a connection problem of the print head cable to either the print head or electronics.
Often, a cause for this error a poorly connected print head cable. This may have occurred during transport of the printer, or after the printhead has printed for many hours. Fortunately, this can easily be checked by reseating the printhead cable:
Please check that:
- All wires connected to the print head are securely fixed and in good order
- The connections on the motherboard are secure
If the problem persists, please raise a ticket above.
