How to solve the charging ink dot problem of the small character inkjet printer, first of all, we must first understand the working process of the small character inkjet printer, so as to determine the cause of the problem, and then prescribe the right medicine, analyze and solve the problem step by step. The working principle is that after a certain pressure, the ink is ejected from a nozzle of the cij printer, and the ink is divided into red ink dots (ink droplets) to charge the ink droplets according to the demand; after that, the ink droplets with different electricity charges are charged in a high-voltage electric field. It is deflected under the action of electric field force; finally it moves and gets some graphic information. It can be seen that ink drop charging is an important link for small character cij printers to achieve inkjet printing. However, various problems often arise in this link. What is an ideal ink drop charging? The printers are all grounded, and the ink is all conductive. Therefore, if the strength (amplitude) of the crystal vibrating rod is not enough, the ink dots are not easy to form. Such ink dots cannot be charged in the charging tank. Since the ink dots cannot be separated, it is equivalent to grounding and basically cannot be charged. If the strength (amplitude) is too large, the ink dots have been broken and become dots one by one. Such an ink dot can hardly be charged in the charging tank because it is an isolated ink dot. When will the ink drop be charged and powered on? Charge at the moment when the ink dots are about to separate. Then the ink dots are separated immediately, so that it can not only be charged, but also keep the power on the ink dots. In order to ensure good charging, the inkjet printer has a circuit to detect charging, also called phase detection. If the charging is not good, it will report the charging ink dot detection failure. What problems will occur when charging ink dots to detect coding equipment? 1 Split is not good. It is caused by inappropriate modulation voltage and inappropriate pressure. 2 The ink viscosity is not normal, and it may even be that the crystal shaker is broken. The ink is transformed, and the water in the ink strikes and charges. 3 The charging slot is dirty and ink is stuck. 4 The charging slot is broken. How to solve the problem of charging ink dot detection? 1 Check whether the split is normal, if not normal, adjust the modulation voltage and observe the change. 2 Check whether the charging tank is dirty. If it is dirty, clean it to check whether the set value and the selected value of the ink viscosity are too different. You can judge the viscosity of the ink. This problem can be solved by changing to a new ink. 3 In this way, we can easily solve the problem of charging ink dots in small character cij printers, and we can actually solve practical problems for customers, make breakthroughs in innovation, and steadily improve. The above is the main points of the cij printer in this issue of how to solve the charging ink dot problem of the small character inkjet printer.
