Inkjet printers can be divided into solid and liquid ink jets according to their working principle (now more common in the latter), while liquid ink jets can be divided into bubble (canon and hp) and liquid piezoelectric ( Epson). Bubble jets use heated nozzles to create bubbles in the ink and spray them onto the print media. There are many brands in the inkjet printer market. So, what do you know about the price of Lenovo color inkjet printers? What is the working principle? Want to know the price of Lenovo color inkjet printer, in fact, the price of different models is also different, this depends on what model you choose to determine the price. The following is an introduction to the working principle of inkjet printers. Thermal inkjet technology uses a thin film resistor to heat less than 0.5% of the ink in the ink ejection area to form a bubble. The bubble expands at an extremely fast rate (less than 10 microseconds), forcing the ink droplets out of the nozzle. The bubble continues to grow for a few microseconds before disappearing back to the resistor. When the bubble disappears, the nozzle's ink retracts. The surface tension then generates suction, drawing fresh ink to replenish the ink ejection zone. Thermal-inductive inkjet technology is structured by such an integrated cyclic technology program. In the piezoelectric ink jet technology, the ink is ejected by a nozzle similar to the heat-sensitive ink-jet technology, but the formation method is formed by reducing the area where the ink is ejected. The size of the discharge area is controlled by applying a voltage to one or more piezoelectric plates in the discharge area. Because the ink is prone to chemical changes at high temperature, the directionality and volume of the ink particles are not well understood, and the edges of the printed lines are jagged, which affects the print quality to a certain extent, which is an inadequacy thereof. The micro-piezoelectric print head technology utilizes the characteristics of discharge when the crystal is pressurized, and ejects the ink stably at a normal temperature. It has a strong ability to control the ink droplets, easy to achieve high-precision print quality of 1440dpi, and no need to heat when the micro-piezoelectric inkjet, the ink will not change due to chemical changes in the heat, it greatly reduced the requirements of the ink. Liquid ink jet printers produced by Epson, Canon and Hewlett-Packard represent the mainstream products in the market. Inkjet printers require a series of complicated procedures when printing images. As the printer head quickly scans through the paper, the countless nozzles on it eject countless droplets, which form the pixels in the image. On the head of the printer, there are generally 48 or more independent nozzles that eject different colors of ink. For example, the 48 nozzles of the Epson Stylus photo 1270 can be used to eject 5 different colors: cyan, magenta, yellow, light blue-green, and reddish-purple, in addition to 48 nozzles that eject black ink. In general, the more nozzles, the faster the printing speed. The ink droplets of different colors fall on the same point and form different complex colors. With the microscope, the yellow and blue-purple inks are observed to be green at the same time, so we can think of this: the printed base color is formed in the ink-jet overlay. By observing the simple four-color inkjet operation We can easily understand how the printer works: Each pixel has 0 to 4 ink droplets over it. As shown below, different combinations can produce more than 10 different colors. Some printers can also produce 16 different colors by a combination of colors, such as "Cyan and Black" or "Red Violet, Yellow, and Black."
