With the machine powered off and the printer head at room temperature (24℃), use a multimeter to measure the resistance of the "T0" NTC line of the printer head. It should measure around 95KΩ. If not, it indicates an abnormality in the "T0" NTC line of the printer head. Please try replacing the printer head.
The above troubleshooting methods did not resolve the issue. It is recommended that you create an after-sales work order to feed back the process and results of the previous inspection to the after-sales engineer. After-sales engineers will help you solve the problem. (Reply time :1 working day)
