When the nozzle of the UV flatbed printer reaches the end of its service life or becomes clogged, it needs to be replaced. So how to install it correctly? If installed improperly, it is likely to cause the nozzle to become invalid. Now, the editor will explain it to you.

1. Before installation, it is necessary to ensure that the grounding connection of the UV safety printer is normal, and that the power supply voltage of the nozzle is stable. At this point, it is necessary to use a measuring table to check if there is static electricity on the main components.

2. Next, we will use software to test whether the UV tablet machine can work properly, check whether the grating reading is normal, and whether the indicator light is on. In addition, the operator's hands should be dry and free of sweat or water vapor. If the hands are too wet, it is easy to touch the nozzle line and cause a short circuit.

3. Check if there are any raised pins on the data cable of the UV flatbed printer nozzle. If possible, it is best to use a manual plug and then plug the plug into the nozzle, being careful not to tilt it. Under normal circumstances, the wire ends on the nozzle are marked with both sides, with one side touching the circuit and the other side not touching the circuit. Therefore, it is important to be careful not to mistake the direction. After inserting, carefully check to ensure accuracy before installing the nozzle onto the trolley frame.

4. After installing the nozzle, it is necessary to repeatedly check it 3 to 5 times to ensure that there are no problems before turning on the power. At this time, it is best not to turn on the nozzle first. Instead, use a spray pump to draw ink over before turning on the nozzle power. If the flash spray is normal at this time, it indicates that the spray installation is correct. If abnormal flashing is found, immediately disconnect the power and investigate other causes.
