The core component of the inkjet printer is the nozzle, but the plug will be caused by long-term shelving of the printer or improper operation and poor ink quality. If it is not repaired in time, it will not only affect the production progress, but also cause permanent plug and make the printer scrapped. However, if the cost of changing the nozzle is very high, it is necessary to master some plug treatment methods. At ordinary times, attention should also be paid to maintenance to reduce the occurrence of plug phenomenon, so that the visual inkjet printer can be used for a longer time.

There are two main types of inkjet printer nozzle structure: all-in-one and separate. The structure of the all-in-one machine needs to replace the ink head and the ink box together after the ink box is exhausted. The mechanism is relatively tightly combined and has high reliability, but the relative cost is high. The ink head and the ink box of the separated structure are separated, and the ink can be replaced separately after the ink is used up, which can save the cost to a certain extent.

The main reasons for the blockage of inkjet printers are: due to the poor sealing or long-term placement of the print head after normal printing and returning, excessive evaporation of water, resulting in dry ink particles at the tip of the fine print head, making the ink unable to be ejected normally; Or different inks are mixed with each other, resulting in chemical reactions, which are usually manifested as frequent faults such as disconnection, color loss, blurred handwriting, and even failure to print normally.

inkjet printer head mainly soft plug, hard plug two categories. Among them, the soft plug is a disconnection fault caused by the increased viscosity of ink on the nozzle for some reasons. Sometimes it is only attached to the surface of the nozzle of the ink outlet. Generally, it can be recovered by dipping the original ink and cleaning for many times. The advantage is that the operation is simple and fast, without any physical damage; the disadvantage is that the cost is high and the ink is wasted. Or use the print head cleaning function in the application tool of the printer driver to clean, which is simple and convenient, and quick to operate. The disadvantage is that the cleaning effect is not ideal.

Hard plug is caused by chemical coagulation or impurities in the nozzle, the fault treatment method can use the following four methods: immersion method, pressure cleaning method, distilled water cleaning method, ultrasonic instrument cleaning method.
