First check whether the filaments completely pass the filament detection sensor. Then reinsert the cable of the sensor.
¶ 2)Filaments sensor malfunction
Please use one wire to connect the two cores in this port to make the circuit closed-loop. Then click the print model. If the printer no longer prompts an error, it indicates that the consumables detection switch is faulty. Replace the consumables detection switch with a new one.
