The head surface of the sprinkler is very fragile, it must not be bumped, and it must be protected. Its surface layer is an aluminum sheet, and the inner layer is coated with a crystal oscillator and a very small ink tube. Once touched, it will be concave, deformed, or even broken, and the nozzle will be scrapped 2. Be careful when installing the nozzle, be sure to cut off the power first and install it in place. After installation, gently push the trolley with your hands to move it left and right to check whether it is smooth. Don’t turn on the power after it is installed, because if the head is not in place, the trolley will easily break the head when it moves. , Strong controllability 3. When connecting the plug and cable, do not bring ink, and make sure that it is in good contact with the socket and does not touch the feet, otherwise it will cause the print head to be short-circuited and burned 4. The steel shaft should also be clean and smooth. You can wipe it with a paper towel with some lubricating oil. Do not directly add oil to the shaft. The excess oil will flow to the nozzle and cause damage 5. After the machinery and circuit are all correct, check the water circuit. First, check that the amount of water in the ink cartridge is insufficient second, check whether the small cleaning blade and the ink suction pump are dirty
