Technology is good, but the degree of recognition is not high. Why is OKI's printing Road rough?

Talking about the status of laser printing products with friends today, when talking about this topic, I can't help thinking of the status quo of OKI in a hundred years. At this time, a friend may ask questions. Isn't OKI producing needle printing products? How can there be a laser printing product? Why are there so few LED print products of OKI in the market? The author is wondering: why is the way of OKI printing so bumpy?
OKI is a 100 year enterprise established in 1881. The Chinese translation is called "Chong electric". In China, it is established in 2006, the day Chong commercial (Beijing) Limited company. The main business is two parts of the needle type printing product and the LED printing product. Today we are going to say this LED printing part.
Since 2014, the national copy machine Standardization Technical Committee confirmed that the difference between the LED printing technology and the traditional laser printing technology is only different from the exposure light source. The LED printer uses the LED light source, and the laser printer uses the laser light source to expose. But they belong to the way of printing products by electronic photography, so they belong to the category of LED printing products. This is for the same category but the two products of different print technologies on the competing road.
LED printing technology for OKI to develop more than ten years of core printing technology. Since 1998, the LED printing technology and laser printing technology have become the two major technology schools of page type printing products (HP's PageWide and EPSON array type printing products for the follow-up of page printing technology). OKI started producing LED printers in Chinese factories in 2005, and played a positive role in the promotion of LED printers in the domestic market. During the period, some brands participated in the development of LED technology. After encountering R & D difficulties, many manufacturers chose to quit. At present, there is only one OKI print product in the market, which uses LED printing technology. Other brands using LED printing technology products are scarce. The market of LED printing products volume is small, after all is still the main theme of the market in laser printing products. Since the "first" is not loud, a quiet market test cannot clap with one hand, but on the LED printing technology!
1. Is the advantage of LED printing technology true?
What makes OKI still adhere to LED printing technology and products under the condition of low market recognition? The author thinks that this is mainly due to several advantages of LED printing technology, but also has different views on some of the so-called advantages.
1. printing speed
The technology used in LED printers is a set of light-emitting diode LED to achieve scanning sensitivity imaging. LED photoreceptor imaging uses dense LED arrays as light transmitters, transforming the electrical signals of data information into optical signals, and then radiated to the photoreceptor drum. The imaging technique of laser printing is to send all the data signals to a transmitter, and the emitted light is reflected on the photographic drum after a rotating prism is reflected. In this way, the imaging process of the LED technology is much simpler than the laser imaging process. In this way, the LED printing technology is theoretically slightly better than the laser printing.
But this is not the case. As we all know physics, we should know how fast the photoelectric speed is, and the shortening of the optical circuit will have little effect on the printing speed. Whether it is the laser type printing product or the printing speed of the LED printing product, we can roughly attribute it to two aspects, one is the speed of the motor and the other is the preheating speed of the fixing unit. The former is responsible for the continuous printing speed, that is, the nominal speed of the product itself, which mainly affects the printing speed of the home page. Of course, there is also the effect of printing memory and processor on printing speed when printing a large number of documents.
2. product volume
The use of LED light source also helps to reduce the volume of the printer. Because there are no mechanical parts in the LED light source system and the peripheral optical devices are less, a large number of LED light emitting units can be integrated into very small devices with the help of advanced technology. There are more complex optical devices and mechanical parts in the optical system of the laser printer, and there must be a certain space between each device to ensure the normal transmission of the laser beam. At the same time, the deflection angle of the laser beam can not be too large in the process of transmission, otherwise the printing quality will be affected, which leads to the body of the laser scanning box. The product is larger. Especially for the color laser printer with one imaging technology, there are four laser scanning boxes inside.
Although the volume of LED printing products will be less than the laser printing technology in theory, in the actual product, we do not see the volume difference between the two technologies.

3. energy saving and environmental protection
As we all know, the LED of the cold light source under the same power is more efficient than the heat source laser. The fact that the LED light source is more energy saving is an undeniable fact. And the laser source will cause damage to the body due to the ozone generated by the energy ionization from the general assembly. At present, a lot of contact type photosensitive drum charging rolls are used instead of the earlier ionization charge roller to reduce the amount of ozone generated by the charging drum charging circuit, improve the photosensitive characteristics of the photosensitive drum to reduce the emission energy of the laser. At present, the amount of ozone produced by every laser print product is within the limits stipulated by the state.
The author has measured the corresponding LED print products, and its running power and standby power consumption are 40% and 87% less than that of competing products, which is worth affirming. The ozone problem has been asked by the technical staff in the industry, which says that although the ozone problem is a common disease of laser printing products, the ozone generation will be available to the human body unless the current laser printing product ozone production is calculated unless the printing task is printed over a million pages in a small space. The probability of occurrence is extremely low based on the existing user habits.
Two, resolution is a topic that LED printing technology can't avoid.
When the resolution of the desktop ink-jet printing product is up to 9600dpi, the highest resolution of the laser printing product is 2400dpi, but at present, the resolution of OKI's LED printing product is still in the 1200dpi stage. Why is there such a big drop?
This is mainly due to the volume of the LED single luminescent body, the current 600dpi resolution LED printing product, whose single light head is approximately integrated with 5000 LED light emitting units, and more than 10000 LED luminescent units are integrated on the single light head of the middle and high end LED print products of 1200dpi resolution. With the enhancement of the discrimination rate, the number of LED luminescent units is followed. Double growth, but the surface area of single head does not increase, forcing the volume of LED light-emitting unit to be nearly doubled. According to the existing market environment, even the technical difficulties of attacking the volume of the LED light emitting unit, the production cost and the sales price are not within the acceptable range of the market.
Even if the above technology and production cost are solved, the interference of light in such a large LED light emitting unit needs to be solved urgently. At present, there are two main ideas to solve the problem. One is to illuminate the LED light source, and the other is to close the single light head with the distance of the photoreceptor. These two ideas cannot be achieved according to the current technological conditions.
Three. Summary:
According to the previous article, OKI's winning LED printing technology is better than the traditional laser printing technology, but there is no advantage in speed and product volume. In the face of users who have already experienced high resolution printing, the LED printing technology has become a full line production problem on the print discrimination rate. The mishap.
At this point, in the touch screen has been popular today, and then back to see all the products on the OKI official network, I found that the existing sales of OKI products in the operation or rely on the traditional keys. From the point and the surface, OKI should not indulge in LED printing technology. We need to take a look at the hot selling products in the market. Although the road is rough, maybe another thought will feel out of the broad road!
