Q：How to check the ink cartridges？

A：Before the inspection, we need to prepare ink cartridges, hoses, masking paper, water. First of all, when you receive the cartridge. You should first check whether the cartridge nozzle is broken. Secondly, to test whether the ink cartridge will leak. We need to plug the cartridge nozzle with a hose to prevent water leakage, and fix it with masking paper. Then inject water into it and leave it for a while to see if there will be water leakage at the various ports of the cartridge. If it does not leak, it means that there is no problem with the cartridge.👉🏻To know more, please click here！

Please wear non-woven gloves before taking out the film to avoid scratching the film with your nails. Gently stretch the film without touching other items. Be careful when receiving the film. First, fix the printing film bracket on the left side, loosen the printing film bracket on the right side, fix the printing film on the left bracket first and finally fix the printing film on the right bracket, and lock the right bracket.👉🏻To know more, please click here！

Q：How to maintain the machine during a long holiday？

A：First of all, you need to make sure that all the ink dampers are firmly fixed above the print head. Then, please check all the ink pipes. See if there is enough ink in the pipes. If there is air in the ink pipes. Then you need to use the loadink function. Please click on the setting page of printexp software. Then use the loadink function(Please select all heads). Click the loadink button. You can pause it after about 35 seconds. Then, please use the "CLEANING" function of the printer. Wait for the printer to complete the instruction. Then please click the "CHECK" button and do the nozzle test. If you get an incomplete nozzle test pattern. Then you need to do nozzle cleaning and testing again until you get a perfect nozzle test chart. This is a complete pattern of nozzle test. Finally, we need to empty the ink in the waste ink pipeline. You need to get the print head off the ink pad. Then use paper to block the X-axis limit sensor. Then please use the loadink functionin printexp software. Because the sensor is covered by paper,the print head will not go home. At the same time, please inject pure water into the ink pad with a syringe. The pump will pump the water down. This enables us to achieve the purpose of cleaning the pipes. Until the liquid in the waste ink tubes becomes transparent. Then we have completed all the steps. Please take the paper off the sensor and restart the printer. Return the print head directly above the ink pad(This is very important). Shut down according to the normal process, ensure that the nozzle and ink pad can beclosed properly after shutdown. It is best to do nozzle cleaning every 10 to 15 days. You need to turn on the cleaning.👉🏻To know more, please click here！
