If the machine reports an error (that is, the red light flashes when the machine is turned on), it is not necessarily that the nozzle is broken, but there may be a problem with the frame or the main board. In this case, you can solve the problem of the error first and then decide to buy the nozzle. 2. Both the main board and the print head are burnt out, first replace the main board, and then check the print head. 3. Check whether the data cable is split, corroded or burnt out. If the data cable is damaged or not inserted properly, it will burn the nozzle and the motherboard. Be sure to check the data cable. 4. For the machine that is too old, such as a lot of ink inside, the machine is very dirty, it is recommended not to change the nozzle, it is best to replace the machine directly. 5. It is recommended that you determine whether your ink cartridges or inks or continuous supply are of good quality. For the continuous supply that has been used for a long time, the continuous supply that is very dirty, and the continuous supply that has a lot of dust and ink sprinkled everywhere, it is recommended to replace it.
