The ink-jet printer has a high scientific and technological content, and its parts are very precise. The correct use and operation of the printer plays an important role in reducing the probability of printer failure and extending its service life.

When inkjet printers print images, they need to carry out a series of complicated procedures. When the printer nozzle quickly sweeps the print paper, the innumerable nozzles on it will spray innumerable small ink droplets, thus forming the pixels in the image. There are generally 48 or more independent nozzles on the printer head to spray ink of different colors.
