Remove the protective cover from the nozzle
Now remove the nozzle and perform an ultrasound.There are two screws, let’s gently loosen them
Note that there is an O-ring here, please do not drop it
Wash the ink residue in the O-ring with a cleaning kettle
Put the nozzle into the ultrasonic wave and pour in the cleaning solution. The cleaning solution should have just passed through the nozzle
Plug in the power and cover it. Heat it and it will melt. Ultra iron objects can be heated, while ultra plastic objects should not be heated. Rubber melts when heated. If there are accessories such as solenoid valves, pumps, or nozzles on them, as long as there is no rubber or O-ring, ultrasonic ultrasound can be used. The O-ring will deform once it is replaced, so it needs to be removed before being replaced. Otherwise, the O-ring may have aged.
