The Function of Nozzle Film on Portable Inkjet Printer

Printhead film is a film that is attached in front of the nozzle, usually which is called nozzle film. Portable Inkjet Printer nozzles and the film have tiny holes arranged in neat, using a piezoelectric crystal (PZT) converting electrical energy into kinetic energy of droplet and spray it on the products, to ensure that the droplet out of the nozzle film formed designed Coding of text, graphics, or barcodes.

        Nozzle film is a film made of polyimide, which should be carefully protected in the nozzle assembly and disassembly, cleaning, soaking. If damaged by hard objets, the rays of the printhead won"t be straight and will have a bad effect on the printings. Once the nozzle membrane damage or loss, the nozzle can not be used any more, so always pay particular attention to the protection of the nozzle when using portable inkjet printer.
