Development History Of Inkjet Printers From Scratch

Jan. 10, 2020

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 is not so simple to operate, just as the principle of calculus is not complicated, and how to use the complicated ones. The following printer supplier introduces several historical breakthroughs in inkjet printer technology breakthroughs.

History of inkjet printers:

In 1976, the first inkjet printer was born:

Inkjet printing technology was proposed as early as 1960, but the first commercial inkjet printer was born at IBM after 16 years. The original IBM4640 was developed by Professor Hertz and his colleagues at the Lutheran Institute of Technology in Sweden, Europe. , Called continuous inkjet technology. The so-called continuous inkjet is to produce ink droplets in a continuous manner regardless of the printing or non-printing, and then recover or disperse the non-printing ink droplets. However, this technique uses ink to print ink on paper. The effect is imaginable, so it has no practical value in reality.

In 1976, piezoelectric ink dot control technology came out:

In the same year as IBM4640, Zoltan, Kyser and Sear, three pioneering researchers of Siemens Technology, successfully developed and developed piezoelectric ink dot control technology (predecessor of EPSON technology) in the same year. The printer was mass-produced in 1978 and became the world's first inkjet printer with commercial value.

In 1979, Bubble Jet was launched:

Japanese researchers at Canon successfully developed Bubble Jet bubble jet technology. This technology uses a heating element to instantly heat the ink in the nozzle to generate air bubble formation pressure, so that the ink is ejected from the nozzle and then the physical properties of the ink are used to cool the hot spot Air bubbles fade, thereby achieving the dual purpose of controlling the dot in and out and size. Here is a small story of the company. One day in July 1977, Endo I of the 22nd Lab of Canon Product Technology Research Institute, Meguro-ku, Tokyo, accidentally put a heated soldering iron on the laboratory while conducting experiments in the laboratory. When the needle was attached, ink quickly flew out of the needle. Inspired by this, the bubble jet technology was invented 2 years later.

At the same time, Hewlett-Packard also invented essentially the same technology. HP and Canon both claimed to be the first researchers to invent the inkjet printing technology to establish their position in the inkjet printing field. However, the concept of "bubble" has been snatched by Canon, HP had to name it Thermal lnk-Jet.

Digital Printer

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

In 1991, the first color inkjet printer and large format printer appeared:

HP DeskJet 500C is the world's first color inkjet printer. In June 1994, the locally transformed product HP DeskJet 525Q appeared in China. HP DesjgnJet is the first time that HP has applied its thermal inkjet printing technology to large format printers. In the world, the world's first monochrome large-format inkjet printer was launched. The emergence of color inkjet printers and large format printing are the most important milestones in the history of inkjet printers.

In 1994, micro piezoelectric printing technology came out:

As early as the 1970s of the last century, Epson began research on piezoelectric technology. After nearly 20 years, it finally successfully applied micro-piezo printing technology to the field of printers and realized productization. The basic principle of microvoltage technology is to place many tiny piezoelectric ceramics near the nozzle of the print head of an inkjet printer. Using the principle that the ink will deform under the action of voltage, the ink in the nozzle is ejected and formed on the surface of the output medium. pattern. Since then, Epson's intelligent ink drop conversion technology, natural color reproduction technology, ultra-fine micro drop technology, etc .; Canon's professional photo optimization technology, quadruple color control technology; HP's Fulitu layering technology, intelligent color enhancement technology, etc. Both have further improved the technical content of inkjet printers.

In 2011, Lenovo's RJ600N optical ink printer was launched:

Memjet technology applied to Lenovo RJ600N optical ink printer is an extension of inkjet printing. What is Memjet? Mem in Memjet refers to a microchip technology system, and Jet refers to an inkjet-like printing technology. This technology has been studied for more than 10 years at an unknown Australian company, Silverbrook Research. Using Memjet technology, Lenovo successfully launched a commercial RJ600N inkjet printer, achieving a breakthrough of 60ppm in inkjet printing speed.

Lenovo RJ600N color printer inkjet head uses Micro-Electro-Mechanical System (MEMS) technology, and the smallest component size is only a few microns. The A4 format printhead array is equipped with 11 microchips, each of which has 6,400 inkjet heads, and a total of 70400 inkjet heads, enabling full-frame printing with the same width as the A4 format. This means that technology brings The printing method does not need to move the print head to the left and right like most inkjet printers on the market, so it realizes the advantage in printing speed.
