The printer is normally turned on, and there is always a high-voltage alarm when the cover is closed. There are generally three reasons for the failure analysis: 1. The nozzle of the printer is dirty and the ink line is deflected; the solution is to clean the nozzle of the printer and clean and dry the nozzle of the printer. 2. The word height of the printer is too high; reset the height of the printer. 3. The high-voltage detection circuit of the printer is too sensitive; the high-pressure alarm value of the printer must be reset under the guidance of the engineer. Schedule: The printer is normally turned on, and there is always a high-pressure alarm check reason and solution comparison table when the cover is closed: the reason Solution The nozzle is dirty and the ink line is deflected Clean the nozzle, clean and dry the nozzle Word height is set too high Reset font height High voltage detection circuit is too sensitive Reset the high pressure alarm value under the guidance of the engineer Half Shell Mussel,Frozen Cooked Half Shell Mussel,Seafood Frozen Half Shell Mussel,Frozen Half Shell Mussel Shengsi Xiangyuan Aquatic Products Co.,Ltd., , https://www.mytilus-edulis.com
