                                                                                                                For uv flatbed printers, no matter which manufacturer does not dare to say that there will be no problem, but there are many problems because they don’t understand, and they don’t know enough to start. Let’s share some common problems about uv flatbed printer and the causes. And basic processing results.

                                                                                                                Power-on reset abnormality (1) Phenomenon: After power-on reset, the machine head rises before and after the Y-axis but does not move left and right; Solution: 1. Check if the X drive is working normally; 2. Check whether the square fiber cable is in contact with bad break.
                                                                                                                Power-on reset exception (2) Phenomenon: After the power-on reset, only the rising Y-axis does not move. Solution: 1. Check whether the emergency switch on the machine panel is closed; 2. Check whether the anti-collision switch on both sides of the device is closed; 3. Check if the Y drive is working normally; 4. Check whether the optical fiber of the round head is broken or not.

                                                                                                                Abnormal operation of the water tank Phenomenon: After the water tank is opened, the water tank emits a large beep. 1, the cause of the failure: not filled with water; solution: turn off the power, fill the water, restart the power; 2, the cause of the failure: the water cycle is abnormal, the flow meter does not detect the return water; Solution: check whether the water pipe is folded or the flow meter Whether it is normal; 3, the cause of the failure: the water temperature is too high. Solution: Stop using immediately and check the cooling unit and set the cooling temperature.

                                                                                                                The uv light does not light. 1. The cause of the malfunction: The uv light control was accidentally turned off in the software. Solution: The uv light control is correctly set in the software; 2. The cause of the fault: poor signal line contact or breakage. Solution: Re-insert the signal line or replace the new signal line; 3. Fault reason: the water temperature is too high; Solution: Stop using it immediately, check whether the water pipe is folded or blocked, re-enable after processing, set the cooling temperature; The cause of the malfunction: The water tank has failed; Solution: The water tank is overhauled.

                                                                                                                Printed pictures have horizontal stripes 1. Cause of failure: The nozzle is in poor condition. Solution: The nozzle is blocked or obliquely sprayed, and the nozzle can be cleaned; 2. The cause of the failure: no step value is adjusted. Solution: In the print software settings, the machine settings enable the maintenance flag to correct the step.

                                                                                                                Large color deviation 1. Cause of failure: The picture format is wrong. Solution: The picture mode is set to CMYK mode and the picture is changed to TIFF. 2, the cause of the failure: the nozzle is blocked. Solution: Print the test strip, if it is blocked, clean the nozzle; 3. Fault reason: The software setting is wrong. Workaround: Reset the software parameters according to the standard.

                                                                                                                The edge of the picture is blurred and flying ink. 1. The cause of the malfunction: the picture pixel is low. Solution: Picture DPI300 or above, especially printing 4PT small font, need to raise DPI to 1200; 2, the cause of the failure: the nozzle and the printed matter are too far away. Solution: Keep the printed matter close to the print head and keep a distance of about 2 mm. 3, the cause of the failure: the material or machine has static electricity. Solution: The outer casing of the machine is connected to the ground wire and the surface of the material is rubbed with alcohol to eliminate static electricity. Use an electrostatic processor to eliminate surface static.

                                                                                                                The printed picture is scattered with small ink dots. 1. The cause of the malfunction: the ink is precipitated or the ink is broken. Solution: Check the status of the nozzle, whether the ink fluency has deteriorated, and check if the ink path is leaking. 2, the cause of the failure: the material or machine with static electricity. Solution: The ground wire of the machine casing, the surface of the material wipes the alcohol to eliminate static electricity.

                                                                                                                There is ghosting in the horizontal direction of printing. 1. The cause of the malfunction: The grating strip is dirty. Solution: Clean the strips. 2. Cause of failure: The raster decoder is damaged. Workaround: Replace the new raster decoder. 3, the cause of the failure: poor contact or failure of the square fiber line. Solution: Replace the square fiber cable.

                                                                                                                Printing ink drops or broken ink Dropping ink: A certain nozzle drops ink during printing. Solution: 1. Check if the negative pressure is too low; 2. Check if there is air leakage in the ink path.

                                                                                                                Broken ink: A certain color often breaks ink during printing. Solution: 1. Check if the negative pressure is too high; 2. Check if the ink path is leaking; 3. If the nozzle has not been cleaned for a long time, if it is, clean the nozzle.

                                                                                                                小泽玛利亚 樱井步 苍井空 石黑京香 桃谷绘里香 白咲舞 川岛和津实 黑泽爱 樱井步 小泽爱丽丝 七濑茱莉亚 樱朱音 原千寻 若菜奈央 稻森丽奈 尾野真知子 友田真希 花野真衣 雪本芽衣 雨宫真贵 冲田杏梨 高阪保奈美 霞理沙 泽井芽衣 北野望 桃谷绘理香 橋本凉 波多野结衣 仁科百华 柚木提娜 长泽梓 大沢佑香 天海翼 前田香织 前田香织 二宫沙树 铃木里美 希崎杰西卡 麻仓优 麻美由真 原更沙 葵实野理 上原瑞穂 福山沙也加 铃木麻奈美 西野翔 神谷姬 希志爱野 琴乃 希崎杰西卡 秋元里奈 原干惠 杏树纱奈 佐藤遥希 Sato Haruki 前田香织 二宫沙树 仁科百华 樱木凛 秋元里奈 小泽爱丽丝 原纱央莉 浅井舞香 音羽雷恩 天海丽 大泽佑香 百合野もも 里美尤里娅 铃原爱蜜莉 美竹铃 吉沢明步 吉泽明步 早川濑里奈 美竹凉子 松岛枫 佐佐木希 樱井梨花 立花美凉 小泉彩 里美尤里娅 铃原爱蜜莉 美竹铃 松岛枫 佐佐木希 朝美穗香 上原结衣 纹舞兰
