#led imaging

With government, commerce being colored to work increase of demand, color printer market attract to set foot in numerous manufacturers, global printer manufacturers such as Hewlett-Packard, favourable alliance, Epson, Canon, OKI,etc. start one after another, having put out eachly and dominant and printed products and technology, products and printing technology various in style were borned one after another on the market, make consumers lose in all sorts of conceptual dense fog.

LED printing technology rarely known by the people

On the market of color printer, if according to product function and property sort, consumers can basically already tell the products of three kinds of levels, this it is specialized the intersection of printer and products, the intersection of commerce and grades of the intersection of printer and products and small and medium-sized enterprises and family that work the intersection of printer and product. However, if divide according to the printing technology of imaging, so far as not every consumer can speak out. Is the market of color printer how to come to divide and print technically on earth at present? In nowadays global printer field, more general way is dividing according to the imaging technology of the optical scanning, the color printer imaging mode is monopolized by two great key technology, they are LED (Light Emitting Diode) Print and laser printing (Laser) Technology. On the market of color printer of the whole world, two great key technology has divided the major manufacturer into two major groups, a group takes manufacturers such as OKI, C ann on,etc. as the core and advocates LED imaging printing technology, another group mainly dominates laser printing technology with H P, favourable alliance.

For a long time, colored laser printing is considered to be a kind of fast, high-quality official working printing technology, its product emerges in an endless stream too. On the Chinese market, the media reports more concentrating on colored laser printing technology, but ignored another LED printing technology that is rarely known by the people but extremely important.

LED technology is also called the Manifold technology of light-emitting diode, it is one of the earliest and also the most advanced imaging technology in the world. After the 1990s of last century, LED technology of going to growth stage since infancy ran high in the whole world unprecedentedly, LED technical application spread all over and got from traffic to scan each field such as imaging, the printer manufacturer relying mainly on OK I, Canon,etc. promotes LED technology to move to maturity in printing imaging to employ, and with laser printing technology and two major foundation stones called the number to print imaging.

Because the technical maturing of LED imaging, the sight of a lot of printer manufacturers has turned to this one and employed the technical field, even some adopt the technical manufacturer of traditional laser printing to express the interest too. With the prevailing of digital color printer, LED imaging technology has been pushed to the front on the market again. This whiff of driving force mainly comes from the global old brand printer manufacturer OKI Company. OKI technology research and development to LED is more than 20 years, and adopted LED technical color printer to took it to China.

Technical comparison that two kinds are printed

Do LED printing technology and laser printing technology have anything different?

First of all, the two are different in the imaging way of the optical scanning. It is a light emitter that the optical scanning imaging of OKI color printer has adopted the intensive LED array, turn the data electric signal into the optical signal by LED, and illuminate imaging to sensitization and applaud. And the technological image forming process of ordinary laser printer conveys the entire intelligence signal to a light-emitting device, the imaging after revolutionary multiprism mirror reflection of light that transmission produces applauds in sensitization. The advantage of the former's imaging is to guarantee the print speed is swifter, can raise the definition constantly.

Secondly, because LED what technology produce it prints some to be very light, can clearly display slight changes of stroke such as the black small character,etc. when the characters are printed not merely, and can until slight level transition display clearly demarcatedly in the picture too at print image, the manifestation is very clear as the picture that OKI C5100 prints out is on the color level. And the light source of laser printer is arranged in a big container in great numbersly and densely, the high-speed rotation of the container makes laser beam deflect.

Moreover, LED image forming system is complicated like that without the laser printer system, the life-span of light source is longer, use more reliably for a long time. In addition, like OKI LED that printer it is low since it last cost comparison wholly,it can one machine dual-purpose, replace the traditional black-and-white laser printer.

Fourth, laser of laser printer magnetic head must to reach sensitization applaud every smooth data at go on, scan and normalize, while guaranteeing to check completeness in competence to applaud to sensitization the speed of ratation on is limited certainly. LED prints and utilizes many pointolites, does not need tedious scanning course, can also keep printing under the high-resolution at a high speed.

Finally, economize on electricity and there is no peculiar smell of ozone,etc. to produce in LED color printer energy-conservation. What merits attention is because LED technical day by day ripe and their in colored to succeed peculiar advantages like technology, some laser printer manufacturers begin to study this technology too at present.

The observers point out, laser printing and LED are printed and also coexisted for a long time as two great key technology in the world, and is playing an irreplaceable role in each field. Undoubtedly, develop clearer, swifter, energy-conservation, in environment protecting mode color printer constantly as the intersection of OKI and uniform the intersection of printer and manufacturer, will promote the development of market of whole printer greatly.
