Before you install this product, you need to pay attention to:
1.After receiving the print head, if you use a needle tube to inject water to check the nozzle or see if it is blocked, this is a very redundant and dangerous behavior.If the printing effect is not clear, press the machine cleaning button.
2.Be careful when installing the print head, be sure to cut off the power first, and install it in place.
3.When connecting the plug cable, do not have ink on it, and make sure that it is in good contact with the socket.
4.The steel shaft should also be clean and smooth. You can use a paper towel to stick some lubricating oil to wipe it. Do not directly add oil to the shaft. The excess oil will flow to the print head and cause damage.
5.After the machinery and circuit are all correct, check the water circuit. Firstly, check whether the ink volume in the ink cartridge is sufficient; secondly, check whether the small cleaning blade and the ink suction pump are dirty.
6.There will be air in the newly installed print head, so it will not print normally immediately. The printer can only produce perfect results after the air in the head is completely discharged.You can use the machine's own cleaning function for intermittent cleaning(Clean 2 times each time, and then 2 times after 30 minutes) Repeated over-cleaning will cause ink accumulation in the cleaning pump, which will not only cause color mixing, ink leakage, and waste ink.Finally, you can print more pictures to let the print head exhaust air during work.
