How does the printing principle of a high-resolution inkjet printer work? Let's listen to the simple introduction provided by the manufacturer of inkjet printers in Zhejiang Province - Wekada! The printing is accomplished by using a nozzle and a nozzle film. The nozzle film is a layer of film attached in front of the nozzle of the spray head. Usually, this film is called the nozzle film. The inkjet printer nozzles and nozzle membranes are both equipped with regularly arranged tiny holes. Piezoelectric crystals (PZT) are used to convert electrical energy into the kinetic energy of ink droplets and then spray them onto the surface.
Ensure that the ink droplets emerging from the nozzle of the spray head and passing through the spray head membrane form the desired printed characters, graphics, or barcodes. That is to say, ensure that the ink droplets do not spread. The nozzle film is made of polyimide film. During the storage, disassembly, cleaning and soaking of the nozzle, care should be taken; if it is damaged by a hard object, it will cause the jet of the nozzle to be not straight, thereby affecting the quality of the inkjet marking. Once the nozzle film is damaged or falls off, the nozzle cannot be used anymore. Therefore, when using the inkjet printer, special attention should be paid to protecting the nozzle film. Do not collide or wipe the nozzle tip area of the nozzle, and do not immerse the nozzle for a long time or inject cleaning liquid into the nozzle for a long time.
