The three questions you asked can make you satisfied with double-sided printing. It not only saves paper, but also does not cause any damage to the printer, so why not! I think most users use it this way.
The working principle of inkjet printers
Inkjet printers can be divided into solid inkjet and liquid inkjet according to their working principles (the latter is now more common), and liquid inkjet Inkjet methods can be divided into bubble type (canon and hp) and liquid piezoelectric type (epson). Bubble jet technology heats the nozzle to generate bubbles of ink and sprays them onto the printing medium. Similarly, the thermal inkjet technology used by HP uses a thin film resistor to heat less than 0.5 ink in the ink ejection area to form a bubble. This bubble expands at an extremely fast speed (less than 10 microseconds), forcing the ink droplets to be ejected from the nozzle. The bubble continues to grow for a few microseconds and then disappears back onto the resistor. When the bubble disappears, the ink in the nozzle retracts. Then the surface tension will generate suction, pulling new ink to replenish the ink ejection area. Thermal inkjet technology is structured by such an integrated cycle technology process. In piezoelectric inkjet technology, ink is ejected from a nozzle similar to thermal inkjet technology, but the ink droplets are formed by narrowing the area where the ink is ejected. The reduction of the ejection area is controlled by applying voltage to one or more piezoelectric plates in the ejection area. Since the ink is prone to chemical changes at high temperatures and is unstable in nature, the authenticity of the printed colors will be affected to a certain extent; on the other hand, since the ink is ejected through bubbles, the directionality and volume of the ink particles are not good. Master, the edges of printed lines are easy to be uneven, which affects the printing quality to a certain extent. These are its shortcomings. Micro-piezoelectric printhead technology uses the discharge characteristics of crystals when pressurized to stably eject ink at room temperature. It has the characteristics of strong ability to control ink droplets, and it is easy to achieve high-precision printing quality of 1440dpi. Micro-piezoelectric inkjet does not require heating, and the ink will not undergo chemical changes due to heat, so the requirements for the ink are greatly reduced. At present, the liquid inkjet printers produced by Epson, HP, and Canon represent the mainstream products in the market.
There are three common types of printers on the market: dot matrix, inkjet, and laser printers. Dot matrix printers have passed their glory days and are gradually entering the dusk. Although the price of laser printers continues to drop, there is still a certain gap compared with mainstream color inkjet printers, and if you want to use color, the price will be much higher. From this point of view, it is not surprising that inkjet printers have become so popular recently.
Inkjet printers were developed after dot matrix printers and use a non-impact working method. The more prominent advantages include small size, simple and convenient operation, low printing noise, and the ability to print pictures comparable to photos when using special paper. After several years of hard work, inkjet printer technology has made great progress. I think back in 1995, a color inkjet printer cost about 4,000 yuan, and the beautiful women printed out could have skin as rough as Wang Er's pockmark. Up to now, color inkjet printers costing more than one thousand yuan are enough to meet all the needs of ordinary families. Even users who have high requirements for picture quality, such as photography enthusiasts, can get color inkjet printers that cost more than two thousand to three thousand yuan. Find the ideal product among inkjet printers.
At present, inkjet printers can be divided into two types according to the working mode of the print head: piezoelectric inkjet technology and thermal inkjet technology. According to the material properties of inkjet, it can be divided into water-based printers, solid ink and liquid ink printers. Below we will elaborate on them respectively.
Piezoelectric inkjet technology places many small piezoelectric ceramics near the print head nozzle of an inkjet printer, and uses the principle that it will deform under the action of voltage to apply voltage to it in a timely manner. above. The piezoelectric ceramic then expands and contracts, causing the ink in the nozzle to eject, forming a pattern on the surface of the output medium.
The cost of inkjet printheads made with piezoelectric inkjet technology is relatively high. Therefore, in order to reduce the user's cost, the printhead and ink cartridge are generally made into separate structures. When replacing ink, there is no need to replace the printhead. . This technology was originally created by Epson. Because the structure of the print head is relatively reasonable, the size and usage of ink droplets can be effectively adjusted by controlling the voltage, thereby achieving higher printing accuracy and printing effects. It has strong control over ink droplets and is easy to achieve high-precision printing. The current ultra-high resolution of 1440dpi is maintained by Epson. Of course, it also has disadvantages. If the nozzle is clogged during use, the cost of clearing or replacing it will be relatively high and difficult to operate. The entire printer may be scrapped. Products currently using piezoelectric inkjet technology are mainly Epson's inkjet printers.
Thermal inkjet technology allows ink to pass through a fine nozzle. Under the action of a strong electric field, part of the ink in the nozzle pipe is vaporized to form a bubble, and the ink at the nozzle is ejected to the output The surface of a medium to form patterns or characters. So this kind of inkjet printer is sometimes called a bubble printer. The nozzle made with this technology is relatively mature and low-cost, but because the electrodes in the nozzle are always affected by electrolysis and corrosion, it will have a lot of impact on the service life. Therefore, print heads using this technology are usually made together with the ink cartridges, and the print heads are updated at the same time when the ink cartridges are replaced. In this way, users no longer have to worry too much about the problem of nozzle clogging. At the same time, in order to reduce the cost of use, we can often see the situation of injecting the ink cartridge (refilling the ink). Just after the print head has filled with ink, add special ink immediately. As long as the method is done properly, you can save a lot of consumable costs.
The disadvantage of thermal inkjet technology is that the ink will be heated during use, and the ink is prone to chemical changes at high temperatures and is unstable in nature, so the authenticity of the printed colors will be affected to a certain extent; On the other hand, since the ink is ejected through bubbles, the directionality and volume of the ink particles are difficult to control, and the edges of the printed lines are easily uneven, which affects the printing quality to a certain extent. Therefore, the printing effect of most products is not as good as that of the press. Electrical technology products.
There are many products using thermal inkjet technology, mainly used by companies such as Canon and HP.
