The working principle of inkjet printer

Head of technology is the key technology of inkjet printer ink, the ink head type has been from the traditional bubble of hot gas and micro piezoelectric technology dominated. Hot bubble print technology application earlier, mature technology, low equipment cost. But because of the ink cartridge with ink to create pressure under the action of a hot bubble, so the cartridge must become integrated with nozzle structure, so the material are relatively expensive. And because the ink head to work for a long time in high temperature and high pressure environment, nozzle corrosion is serious, also easy to cause drops splash and nozzle blockage. Application of hot gas bubble method of printing color inkjet printers, Canon and HP company's main brand. At present, the total thermal inkjet print head of nozzle can reach hundreds, even thousands, of each nozzle diameter with hair, spit out the OLIVETTI printer ribbon PR3 minimum of 4 drops capacity rose slightly. Three color is green, magenta and yellow ink head is often one of the water, will be a few small colored drops combination, can form different sizes of ink, to produce more abundant harmonic color and smooth halftone. Black ink ink head are separate.
Piezoelectric method with ink dot shape rules, no splash, ink dot size can be controlled, can choose more different chemical epson printer ribbon LQ310
  composition of the ink, the opportunity to reduce corrosion, the advantages of the nozzle life extension. Users can also use powder ink and oily ink, so as to prevent discoloration caused by ultraviolet light and faded. Due to less pressure in micro piezo ink head, nozzle is, in fact, has been replaced by a piezoelectric ceramic chip, is no contact between the nozzle and the cartridge, so head in micro piezoelectric ink and ink cartridges are discrete structure of nozzle, such a nozzle can support multiple ink cartridge, thereby greatly saving the cost of the use of the user. Micro piezoelectric inkjet technology is Epson company's patent technology, the mainstream of latest Epson inkjet printer head. There are 128 black ink nozzle, color ink there are 288 nozzle head (96) of each color, natural resolution of 1440 dpi x 720 dpi. Epson designed for piezoelectric technology development of the ink is very exquisite, has dissolved and quick-drying properties, can rapid permeate into the paper, no flash, no dizzy catch, print quality is very good, especially in the inkjet paper and glossy paper.
