First of all, making sure that the uv flatbed printer is operating normally, the ground wire of the machine is connected normally, and the voltage supplied by the print head is normal! People can use the measuring table to test whether there is static electricity in the main parts of the machine.
Secondly, using the software to test whether the uv flatbed printer is operating normally, whether the raster reading is normal, and whether the indicator light is normal. There should be no sweat or moisture on the hands of the operator, making sure the cable is clean and not damaged. Because it is possible that the print head cable will short circuit when plugged into the print head. Meanwhile, when inserting the ink damper, don’t let the ink drip to the cable, because the ink will directly cause short circuit when it is left along the cable. After entering the circuit, it may cause a short circuit and directly burn the nozzle.
Thirdly, checking if there are any raised pins on the print head of the uv flatbed printer, and whether it is flat. It is best to use a new one and plug it into the print head with a new one. Insert it firmly without any tilt. The head scale of the nozzle cable is generally divided into two sides, one side is in contact with the circuit, and the other side is not in contact with the circuit. Don’t make a mistake in the direction. After inserting it, check it several times to confirm that there is no problem. Install the nozzle on the carriage board.
Fourth, after installing all the nozzles of the uv flatbed printer, check it three to five times. After confirming that there is no problem, turn on the power. It is best not to turn on the nozzle first. First use the ink pump to draw the ink, and then turn on the nozzle power. First check whether the flash spray is normal. If the flash spray is normal, the installation is successful. If the flash spray is abnormal, please turn off the power immediately and check if there is a problem in other places.
If the print head is abnormal, people need to turn off the power immediately and carefully check whether there are other problems. If there is an abnormal phenomenon, please contact the professional after-sales technician immediately that assist them to install and debug.
The normal service life of uv flatbed printer nozzles depends on the situation, choose high-quality ink, and pay more attention to maintaining the machine and nozzles, which can effectively extend the life of the nozzles.
