How do Inkjet Printers Work?

Inkjet printers turn colored liquid ink into fine particles through nozzles and spray them onto printing paper. Some inkjet printers have three or four print heads to print yellow, magenta, and black. Some of them share a single nozzle. Four-color printing. ^[1]

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. This bubble expands at an extremely fast speed (less than 10 microseconds), forcing ink droplets to eject from the nozzle. The bubble continues to grow for a few microseconds before it fades back to the resistor. When the bubbles disappear, the ink in the nozzle retracts. The surface tension will then create a suction force that will draw new ink to replenish the ink ejection area. Thermal inkjet technology is structured by such an integrated cycle technology program. In piezoelectric inkjet technology, the ink is ejected from a nozzle similar to the thermal inkjet technology, but the formation method is formed by reducing the area where the ink is ejected. The size of the ejection area is controlled by applying a voltage to one or more piezoelectric plates in the ejection area. Because the ink is prone to chemical changes at high temperatures, the directionality and volume of the ink particles are not easy to grasp, and the edges of the printed lines are easily uneven, which affects the print quality to a certain extent, which are all its disadvantages. The micro-piezo print head technology uses the characteristics of discharge when the crystal is pressurized to stably eject ink at normal temperature. It has the characteristics of strong control of ink droplets, easy to achieve high-precision print quality of 1440dpi, and the micro-piezo inkjet does not require heating, the ink will not undergo chemical changes due to heat, so the requirements for ink are greatly reduced. Liquid inkjet printers represent the market

Inkjet printers have a high technological content, and the components are very precise. Correct use and operation of the printer has a significant role in reducing the failure rate and extending the life of the printer.

Inkjet printers were developed after dot matrix printers and used a non-impact way of working. The more prominent advantages are small size, simple and convenient operation, low printing noise, and the use of special paper can print pictures comparable to photos, etc. After several years of training, the technology of inkjet printers has made great progress. Imagine that in 1995, a color inkjet printer with a price of around 4,000 yuan could have a rough skin like Wang Ermazi. More than a thousand color inkjet printers are enough to meet all the needs of ordinary families, even for pictures like photography enthusiasts

1. In the process of using color ink cartridges (here, the same-body ink cartridges), pay attention to the balanced use of various shades of red, yellow, and blue. Do not print only pictures that are biased toward one color, as long as one of the ink cartridges is used Color, even if the other colors are not used up, the inkjet cartridge cannot continue to be used. Generally, the higher the resolution of the printed picture, the more ink is used. Light colors consume less ink, and bright red or blue composite colors require more than one basic color combination, and therefore require more ink.

Second, do not switch the printer frequently, because many types of printers will perform a self-test procedure when they are turned on, which will consume ink, try to collect the materials to be printed together as much as possible (but at the same time be careful not to let the printer work for too long) This will also save ink.

3. If the print head of the integrated ink cartridge is blocked, you can take the following measures to improve it:

1. Immerse the print head (excluding the circuit board) in warm water for about 10-20 minutes, and allow the warm water to dissolve the dry dye (note: keep the circuit board dry).

2. Place the print head on top of several soft and dry paper towels, and let the paper towel slowly absorb the residual water and ink from the nozzles. Do not wipe the print head hard. If the cartridge needs to be used immediately, return it to the correct position inside the printer. If not in use, you can purchase a special print head protection (clip) to store it properly. The rubber pad inside the protection (clamp) can block the air and keep the nozzle moist for a long time.

3. Do not print any more when the ink cartridge is out of ink. Printing will burn the print head (because it only uses the power boost print head to eject ink and borrow ink to dissipate heat).

With the rapid development of the Internet, some people predict that the era of paperlessness is coming, and the end of the printer has come. However, global paper consumption is increasing at a rate of double each year, and printer sales are increasing at an average rate of nearly 8%. All this indicates that the printer will not only disappear, but also will develop faster and faster, and the application area will become wider and wider. From the appearance of the world's first printer in 1885,

The basic working principle of an inkjet printer is to first generate small ink droplets, and then use the inkjet head to guide the small ink droplets to a set position. The smaller the ink droplets, the clearer the printed picture. The basic principle seems simple, but it's not that simple. Just as the principle of calculus is not complicated, so is how to use complexity. The history of several technological breakthroughs in inkjet printers is described below.

Time Event Minutes

The world's first inkjet printer was born in 1976

1976 Piezo ink dot control technology came out

Bubble1979 inkjet technology came out in 1979

In August 1980, Canon applied its bubble inkjet technology to its inkjet printer Y-80 for the first time, and began the history of inkjet printers.

The first color inkjet printer and large format printer appeared in 1991

Micro-piezoelectric printing technology came out in 1994

In 1996, Lexmark launched the world's first 1200 * 1200dpi ultra-high-resolution color inkjet printer Lexmark CJ7000 by using EXCIMER argon (ARGON) / fluorine (FLUMRINE) laser cutting technology.

The world's first color inkjet with the highest resolution of 1440dpi and six-color printing in 1998

For users using compatible or refilled ink, here are a few suggestions to keep in mind:

1. Make sure that the nozzle of the refilled ink cartridge is intact;

2.It is best to use high-quality original ink to add ink;

3. Before refilling the ink, the ink cartridges should be thoroughly cleaned, or the two different inks may be mixed to cause chemical reactions, which may cause plugging and other problems. Cleaning the ink cartridge with the built-in software can only solve the slight plugging. It is best to inject water into the ink cartridge with a syringe before refilling. Try not to let the water overflow, and then grasp the ink cartridge with your hand and gently shake it. Let the remaining ink dissolve fully in the added water.

If you use too much force when shaking, the water inside may overflow. At this time, wipe it with a paper towel or cloth immediately to prevent it from penetrating into the chip and causing hardware failure. Continue to use a syringe to drain the mixed liquid in the ink cartridge. Repeat this operation several times until ink is pumped until the color is very light;

4. When filling the cartridge with ink, you must grasp the amount of ink, not too much;

5. To prevent the ink cartridge from being exposed to the air for a long time to block it. Although there are methods to clean it, the ink cartridge should be filled immediately after the ink cartridge is about to be printed. If the printer is not used for a short period of time, the ink cartridge can also be placed in a dedicated ink cartridge storage box. The rubber pad inside can block the air and maintain the nozzle's humidity;

6. After filling the ink cartridge with ink, it is better to let the ink cartridge stand for a few minutes first, so that the ink slowly soaks into the sponge to ensure the printing quality;

7. If it is an integrated ink cartridge (there is a nozzle on the ink cartridge), when refilling the ink cartridge, you must pay attention to the nozzle on the ink cartridge is not damaged, otherwise, the nozzle is damaged and the ink cartridge is damaged.

8. During the use of the ink cartridge, the print head may be blocked by paper fibers, resulting in poor printing results, so it is essential to periodically clean the print head. When cleaning the print head, use wet paper towels and lint-free paper towels to gently clean the edges of the nozzles without touching the nozzles. You can also use the cleaning button on the control panel of the inkjet printer until the printing effect is clear.

There are three types of printers available for home users, student users, SOHO, and business users: laser printers, inkjet printers, and ink tank printers. With the advantages of "saving", "good", and "multiple", the ink cartridge printer has become the best choice for the current printer.

Ink silo printer definition: Ink silo printer refers to the support of large capacity ink silo, which can achieve a single set of consumables, ultra high print volume and ultra low printing cost, and users can enjoy the original factory warranty service including print head printer.
