If the nozzle of the digital printing machine is damaged, we need to replace it with a new one. The following editor of Yanyan will introduce to you the standard operation process of replacing or installing the nozzle of the cotton digital printing machine: The nozzle replacement of the digital printing machine is not particularly complicated. It only needs a few simple steps. The details are as follows: 1. Before installing the print head, first make sure that the cotton digital printing machine is operating normally, the ground wire of the machine is well connected, the voltage on the trolley board is normal, and the power supply voltage of the print head is normal! The easiest way is to use a multimeter Measure whether there is static electricity on the cotton digital printing machine, the voltage of the trolley plate, and the power supply voltage of the nozzle, and then disconnect the nozzle power. 2. Pick up the new spray head, first uncover the vent seal (that is, the label or sticker attached to the spray hole), pour 70~80 water or alcohol, and soak! 3. Then put the nozzle of the cotton digital printing machine nozzle down on the paper towel and drip the ink for about 2 to 5 minutes, until the ink completely penetrates the paper towel, and then connect the nozzle with the ink needle, and use the ink absorber with the nozzle point up. Slowly absorb the air in the pipe, and then rotate the nozzle 180 degrees to slowly absorb a small amount of ink with an ink absorber, and finally wipe the contacts and nozzles with a paper towel to perform the work on the machine. 4.
