In the end the war and who is stronger LED laser printing technology

Demand Office

Along with the increase of the government and the business office needs color, color printer market in the IT market downturn trend thriving, attracted in numerous manufacturers, HP, Lexmark, EPSON, Canon, OKI and other global printer manufacturers have debut, printing products and technology, introduced the advantages of a time on the market, a wide variety of products and printing technology turned out, consumers immediately lost in the concept of the fog, the general situation in order to facilitate consumers understand printing products and printing technology, how to divide has become a key problem.

Color printer in the market, if in accordance with the function and performance of product classification, consumers have been able to distinguish between the three types of basic level products: first class professional printer products, such as HP Color LaserJet 5500, OKI C9000, Epson series of mainstream products such as C8600; second kinds of commercial grade printer products, such as HP Color LaserJet 4600. OKI C7000 series, EPSON C4000; third is the small and medium-sized enterprises and home office printer products, such as HP CLJ 2550, EPSON ALC 1900, OKI C3100 and C5000 series, Minolta magicolor2300w.

However, if in accordance with the imaging printing technology division, I think it is not every consumer can speak. So, the current color printer market is how to print technology? In today's global printer field, the more general way is in accordance with the optical scanning imaging division, color printer and imaging mode is dominated by two core technologies, which is LED (Light Emitting Diode) printing and laser printing technology (Laser).

Historical technology evolution

Color laser printing has long been considered to be a kind of office printing technology is fast, high quality, the products also emerge in an endless stream. In the global color printer market, two key technologies of the mainstream manufacturers are divided into two groups, one group is OKI, Cannon and other manufacturers mainly advocate LED imaging printing technology, another group is HP, Lexmark leading laser printing technology. In the Chinese market, a few years ago, the media reported more focused on laser printing technology, but ignored another little-known, but extremely important and has a long history of LED printing technology.

LED technology is also called light emitting diode technology, is the world's first, one of the most advanced imaging technology. LED the most basic structure includes the circuit containing a plurality of semiconductor wafer and semiconductor light emitting material of small, small semiconductor chip is in the framework of core elements around the cover to protect the role of the epoxy sealing material, as the illuminant of LED can be directly emitting monochromatic light in a tilted forward direction.

LED technology for the first time the business can be traced back to 1960s, because of the efficacy of LED is relatively low, the light emitted is not ideal, so it is very limited commercial value.

70 to 90s, LED is the development of the era, the scientific community and professionals to replace LED new chemical substances, improve the internal system, the high brightness LED unprecedented increase, the more abundant source; LED requirements to voltage no longer can be harsh on the condition of low pressure to achieve efficient operation. At the same time very energy-efficient, at this time, LED has been OKI, Toshiba and other manufacturers are widely used in fax machines, printers, calculators, test instrument, optical fiber data transmission and other fields.

After 90s, from infancy to the growth stage of the LED technology in the world is unprecedented, for further research and development of LED technology at the same time, the application of LED technology in imaging from traffic to other fields, especially in the OKI and Canon based printer manufacturers to promote the technology in LED print imaging applications mature, and with the continuous development of laser printing technology and known as the two cornerstones of digital printing imaging.

Two technical quality

Due to mature LED imaging technology, printer manufacturers many eyes turned to a mature application technology field, and even some have used traditional laser printing technology manufacturers have expressed interest in a technical field. With the popularity of digital color printers, LED imaging technology once again pushed to the forefront of the market, the main driving force from a global veteran printer manufacturer OKI company, OKI is full of confidence for the future of LED technology, and has developed more than 20 years, and its color printers using LED technology to Chinese, in order to facilitate the consumers understand the application effect of this technology, we may wish to OKI high speed color page printer (High-speed Color Page Printer) as an example, the LED printing technology with laser printing technology to do a brief analysis and comparison.

First, two different ways in optical imaging. The optical scanning imaging of the OKI color printer adopts the dense LED array as the light emitter, and transforms the data electrical signal into optical signal through the LED, and then to the photosensitive drum imaging. The imaging process of ordinary laser printer technology is transferring a data signal to all of a light emitting device emits light through the rotation of the prism reflection image on the photosensitive drum. The former is the source imaging with the advantages of smaller volume, short distance, light transmission is not affected by the mechanical transmission limit of optical transmission, to ensure that the printing speed is faster, and with the decrease of LED diameter, can constantly improve the resolution.

Second, because the LED technology is used in tens of thousands of independent digital light emitting diode, capable of handling the subtle changes of print data in print, print generated is very small, not only
