The coexistence of the advantages and disadvantages of coding equipment makes consumers a headache

Current inkjet printers can be divided into two categories: ink inkjet printers and laser inkjet printers. The ink jet printer product was developed early, and the price is cheaper than the laser machine, and still dominates the market. According to the principle, the ink jet printer is divided into continuous ink jet and command jet; according to the font size, it is divided into small font and large font; according to the printing speed, it is divided into super high speed, high speed, standard speed, and slow speed; according to the power source, it is divided into external air source ( Compressed air from outside) and internal air source (from built-in gear pump). We all know that the inkjet printer is a closed loop system composed of ink pumps, solenoid valves, various detection systems and ink pipelines. There is an open circuit in this system, that is, at the nozzle recovery port, the ink passes through the nozzle, charging tank, phase detection and high-voltage deflection plate, and finally enters the closed loop system through the recovery port. The section from the nozzle to the recovery port is an open circuit system. The ink is in direct contact with the air. The power of the recovery port is a Venturi or recovery pump. The vacuum recovery force is generally 50 bar. The inkjet printer uses this recycling force to recycle the ink that does not need to be printed. At the same time of ink recovery, impurities and water molecules in the air also enter the ink system. In order to solve the problem of blocking the nozzle when the impurities flow to the nozzle, the inkjet printer needs to be designed with a filter in the pipeline. However, it is worth noting that in the production experience of inkjet printers, since there is no unified national standard and normative constraint, it is difficult to guarantee the quality of supply of inkjet printer manufacturers on the market. Manufacturers are using their own standard production equipment, which has also led to a situation in the market where shoddy and good and bad coexist. This is a headache for consumers, and it is also a headache for users to purchase The code machine expands the challenge. This has also made the industry and many industry end users have more and more expectations and calls for the national standard of inkjet printers. The inkjet printer is a device that is controlled by software and uses a non-contact method to mark the product. According to the different working principles of inkjet printers, inkjet printers can be divided into three categories: continuous jet inkjet printers, drop-on-demand inkjet printers, and laser inkjet printers. Classified from the consumables used by the inkjet printer: one type is ink inkjet printer; the other is non-ink inkjet printer (laser inkjet printer). In recent years, domestic inkjet printers have grown strongly, and some of their performance has exceeded or exceeded imported inkjet printers. Inkjet printers are widely accepted by users for their wide range of applications and strong applicability.
