What are the advantages of LED printing technology and laser printing technology?

In China, LED printing technology has been applied to products for 12 years. As a follow-up to laser printing technology, LED printing technology products are flat in the market. Even in this case, LED printing is performed under the same performance. The price of the product is much more expensive than the traditional laser printing products. Is it possible that the technology can be improved if the technology is improved and the performance is not improved? What are the advantages of LED printing technology and laser printing technology?

Past and present of LED printing technology

In 1998, OKI, a world-renowned commercial printing specialist, applied "LED" to page printer imaging and began selling "LED printers" worldwide, bringing the performance of page printers to the next level and winning the world. Widely recognized by users. LED printing and laser printing are the two core technologies of digital printing imaging today. The difference between the two is in optical scanning imaging technology.

Seven years later, OKI began producing LED printers in China in 2005, which played a positive role in the promotion of LED printers in the domestic market. During the period, some brands participated in the research and development of LED technology . After encountering difficulties in research and development, many manufacturers chose to withdraw. When LED printing technology matured, Fuji Xerox joined the LED camp in 2008, and Fuji Xerox's SLED technology has already begun to be applied in Fuji Xerox products.

Today, several of the early brands with laser technology are still pushing the laser printer, especially the black and white laser printer has obvious advantages in the market, and has become the first choice for consumers. The innovations of OKI and Fuji Xerox in LED printing technology or SLED printing technology are worth encouraging. Their products still take a long time to promote. In the past 12 years, they have not caught up with laser printers in sales.

In the face of the downturn in market sales, where will the LED development go? This depends on whether the LED printing technology can revolutionize the product. If this technology can make the product cheaper, the production cost and printing cost are lower, the print quality and performance are higher, then it is equipped. LED printing technology products will eventually occupy more market share. What is the truth now?

Different types of technical prices are different

We selected four color laser (LED) printing products with output speeds of around 20 pages/minute for comparison. Please see the following table:

From the above table, we can see that the Fuji Xerox CP228w is a black and color SLED printing product with an e-commerce price of 2,849 yuan. This is the cheapest product of the four products, but the most expensive one. It is a Ricoh SP C252DN with laser printing technology, and its e-commerce price is 4,770 yuan.

By comparison, we can see that the market price of products using LED printing technology is significantly lower than that of laser printing technology. Why are products with LED printing technology at a low price? Why do users still choose the more expensive laser printing products after the LED printing products are released for so many years?

The difference between LED printing technology and laser printing technology

Laser printing technology, whether black and white or color, the basic principle of the two is the same, but the color laser printer adds red, yellow and blue printing units to the black and white laser printer, so not only can print black Documentation, but also the ability to output color documents. Although different brands have different laser printing technologies applied in their products, the working principle is the same.

The light source of the laser printer is a high-power laser diode. Under the control of the printing signal, the photosensitive drum is exposed through a complicated optical component to form an image latent image, and the charged toner is adsorbed by charging, and then transferred onto the paper. Heat fixing, form an image, and finish printing. For color laser printers, the same process is required to complete the color print job four times.

For LED printers, the light source of the printing unit is composed of a myriad of tiny LED light-emitting diodes. Each physical resolution of the printer corresponds to one LED, that is, the more the number of LEDs, the higher the printing resolution. Similarly, under the control of the printing signal, the LED emits light to expose the photosensitive drum, and the difference from the laser printer is mainly reflected in the photosensitive process. Laser printers produce a single point beam through optical components, while LED printers produce a single point beam from a single LED.

However, LED printers are not easy to improve the printing resolution. According to common sense, it is necessary to increase the density of LED diodes to improve the printing resolution, and at the same time increase the signal control chip, the manufacturing difficulty and cost will be improved. Therefore, in terms of printing results, laser printers are superior to earlier LED printers. However, with the development of technology, LED technology is also constantly improving. Fuji Xerox has introduced SLED technology to make up for the shortage of LED technology, which has significantly improved the printing resolution and printing effect.

From the above technical analysis, we can see that the printing products using LED printing technology use fewer light-emitting units with lower energy consumption, so that the product body has fewer volume parts, and the product cost is lower, and fewer parts. It also gives print products a lower failure rate.

Just because of defeat in the last step

The products are sold at a low price, the energy consumption of the products is lower, and the volume of the products is smaller. Why do the LED printing products with obvious advantages still not as good as the laser printing products? After we investigated everything, only because of compatible supplies!

Users who use laser or inkjet printing products are familiar with compatible consumables. Before purchasing printed products, in addition to the performance and price of printed products, the post-use cost of the products is still the most important performance indicator for users. Low-cost and compatible consumables are the key factors.

According to e-commerce search, HP's consumables search volume is as high as 7,400 pieces, Fuji Xerox's consumables search volume is only 4,200 pieces, and OKI's consumables search volume is only more than 500 pieces. Why is the market feedback so? Can compatible consumable manufacturers not see the advantages of LED printing products? Why are there so few compatible consumables for LED printing products?

Chengye LED is also a LED, as a low-power printing technology, its carbon powder outer shell has a lower melting temperature than laser printing technology, and this low-melting point toner production technology rarely has compatible consumables. Manufacturers have the right, so the corresponding low-cost printing compatible consumables are even rarer in the market. As a savvy corporate sourcing buyer, you will not choose a more costly product for a lower price. LED printing products are so grievances in the market today, but from a market perspective, LED printing products can only be used today!
