Small character printer charging ink point detection failure reason
The principle of the small character printer is that a certain pressure of ink is ejected from the nozzle of the printer . The crystal rod is divided into ink dots according to the required frequency (generally constant) and amplitude vibration. Then charge the ink drops as needed. The ink droplets charged with different electric quantities are deflected by the electric field force in a high-voltage electric field, and then through the movement of the product, the graphic information we need is formed. How can I have a good charge? The printers are grounded and the ink is electrically conductive. Therefore, if the strength (amplitude) of the crystal shock bar is not enough, the ink dots are not easily formed, and such ink dots cannot be charged in the charging slot because the ink dots are not separated, equal to the grounding, and cannot be charged at all; if the crystal shock bar is If the velocity (amplitude) is too large, the dots are broken and become one point at a time. Such an ink dot cannot be charged at all in the charging bath because it is an isolated ink dot. When can I charge it? It is the moment that the ink dots are about to be separated, and then the ink dots are immediately separated, so that they can be charged and the electricity can be left on the ink dots. In order to ensure good charging, the printer has a circuit for detecting charging, also called phase detection. If the charging is not good, the charging dot detection failure will be reported. Reasons for charging ink dot detection failure : Handling method for charging ink dot detection failure: Advantages Shenyang Oulang Si Packaging Equipment Co., Ltd. independent research and development of production Oulang Si small character inkjet printer has the following advantages are obvious: Oulang Si V95 small character inkjet printer can print 34 dot matrix, ink system, and through the nozzle Innovative improvements can better adapt to different ink needs. The original ink viscosity detection and liquid level detection technology ensure high-definition print quality of the machine, and it is better suited to anti-migration ink and yellow ink than similar machines. The fully anatomically designed nozzle design completely solves the problem of nozzle clogging that has always existed in the industry and reduces the user's use cost. The magnetically controlled non-contact high-voltage switch is designed to avoid machine failure caused by poor contact after long-term use. Maintenance is simpler and inspection is easier The circuit system is separated from the ink system to avoid accidental damage to the machine during maintenance and use. A drawer-type ink system makes maintenance easier. Direct operation of the ink system with a single valve and pump closure through the menu makes it easier to determine machine failures and eliminate unnecessary maintenance costs. Perfect function, convenient and durable The automatic cleaning of the nozzle ensures that the machine will operate stably for long periods of time. The unique 34 dot matrix design meets the requirements of various logos for customers in different industries. Chinese display menu, built-in 12 dot matrix, 16 dot matrix each three thousand Chinese character library, pinyin input, pattern online editing function is complete. Spin-on ink addition system, plug and play, no need to replace the ink tank, saving consumables. Support data transmission, and can form a complete automated identification system with other electronic devices (such as weighing instruments, computers). Dedicated print fonts and print modes can be tailored to customers with special requirements. WYSIWYG, drop-down Chinese menu, easy to operate. Always maintain excellent coding quality The Oulens V95 small character printer provides clear coding results for different industries; Up to 16 -bit phase control, accurate ink dot splitting position and accurate charging; Specially developed inks developed for optimum print results; Ink temperature, viscosity, pressure real-time detection, automatic correction.
1. The splitting is not good, the reason is that the modulation voltage is not suitable, the pressure is not suitable, the ink viscosity is not normal, and even the crystal shock rod may be broken.
2. The ink deteriorates and there is moisture in the ink that affects charging.
3. Charging point, there is a problem with the phase detection circuit. The charging slot is too dirty and stained with ink , causing the charging slot to break.
It is generally a simple to complex processing method.
1. Check if the split is normal. The modulation voltage can be adjusted abnormally and the change can be observed.
2. Check if the charging slot is dirty. Dirty cleaning.
3. Check if the set value of ink viscosity and the current value are too different? The viscosity of the ink can be judged. The quickest way is to replace the new ink.
