Classification of inkjet printers
Inkjet PrinterThe colored liquid ink is sprayed into fine particles onto the printing paper through a nozzle. Some inkjet printers have three or four printing nozzles for printing yellow, red, blue and black, and some share a nozzle for printing in four colors.
Inkjet PrinterIt was developed after the stylus printer and adopted a non-striking way of working. The significant advantages are small size, simple and convenient operation, low printing noise, and the ability to use special paper to print pictures comparable to photos. After years of development, inkjet printer technology has made great progress. A thousand-yuan color inkjet printer is enough to meet all the needs of ordinary families. Even users who have high requirements for photo quality, such as photographers, can pay 2,000 to 3,000 yuan in color.Inkjet PrinterFind the ideal product.
Inkjet PrinterTwo main technologies are used: continuous inkjet technology and random inkjet technology. Early inkjet printers and current large-format inkjet printers used continuous inkjet technology, while the current popularInkjet PrinterRandom inkjet technology is typically used.
The continuous inkjet system can generate high-speed ink droplets, so the printing speed is high and plain paper can be used. Different printing media can obtain high-quality printing results, and it is easy to realize color printing. However, the structure of the inkjet printer is more complicated than the random type: the ink needs a pressure device, the terminal must have a recovery device, and the working method is not efficient and accurate enough, and now uses this technology.Inkjet PrinterVery rare.
Compared with the continuous ink jet system, the random ink jet system has simple structure, low cost and high reliability. However, the ink droplet ejection speed is low due to the influence of the ejection inertia. In such a random ink jet system, in order to compensate for this disadvantage, many random ink jet printers employ a multi-nozzle method to increase the printing speed. Random inkjet technology mainly has micro piezoelectric and thermal bubble type two categories.
