Last week, we have purchased the brother tn 660 from the manufacturer V4ink. Their workers also have told many things need to be noted about the printer. They said we should shock plus powder cleared must be carried out before the alarm, or even cleared can not take long. It is best to take advantage of a lot of powder to clear, diligently, ground clear zero

Brother printer reset method:
1, the boot case, remove the brother cartridge or drum unit, flat on the desktop, on the right there is a small square This is where the authorities.

2, the toner alarm is certainly at the bottom of the slider, and now carefully with a flat-head screwdriver deep into the gap below the slider, try to turn the screwdriver, leverage the lever pry, slowly by feeling hard, you will listen To the dah sound, the slider is lifted. In a click, the final slider is pushed to the top along the path shown by the curved arrow.Now put the drum unit into the machine, close the front cover, the machine self-test, the yellow Toner light is no longer flashing, indicating that the counter has been cleared. For verification, I printed the machine settings page before and after clearing (quick and continuous press of Go button).

3, to see Toner bar shows that from zero into full, and the color of the print is also deeper, indicating that the machine that full of toner powder. With this method can squeeze the last powder, until completely powder-free powder.From the above settings page you can see, cartridge life will be counted, that DRUM bar is empty, the machine prompts to replace the cartridge, and refused to work. The old print cartridge can still be used, but the print cartridge counter must be cleared as follows:Turn on the front cover, hold the GO key (in this case, the front cover has been opened, you must hold the white button inside the machine, as shown in the circle below), for about 4 seconds, the three lights on the panel Turn on, turn off at the same time, then let go.

4, and then remove the drum unit, then re-load the machine, close the front cover, the machine self-test, complete reset. Press the GO key three times in quick succession to print the setup page, and you can see that the cartridge (DRUM) is full.

To black and white laser printer works, for example, when the computer through the cable to the printer to send data, the printer will first receive the data temporarily stored in the cache, when receiving a complete data and then sent to the printer's processor, The data is processed into a signal group of similar data tables that can drive the print engine action. For laser printers, these signal sets are a set of pulsed signals that drive the laser head to work.
Well, the laser printer began to work, in fact, its core technology is the electronic imaging technology, this technology combines the principles of imaging and electronics to generate images, one of the core components is a photosensitive drum. The laser light emitted by the laser emitter is irradiated on a prismatic mirror. As the mirror rotates, the light sweeps from one end of the drum to the other (through a variety of focusing lenses, so that the light that scans the surface of the drum Point is very small), the drum to 1/300 inch or 1/600 inch step rotation, scanning and in the next line of his line. In fact, the cartridge is a surface coated with organic materials, the cylinder, in advance with a charge, when there is light to the radiation, the site will be the resistance of the reaction. The data sent by the computer to control the laser launch, scanning the drum surface of the light constantly changing, so that there will be some places by the radiation, the resistance becomes smaller, the charge disappears, and some places have not been exposed to light, Charge, and ultimately, the surface of the drum to form a charge by the composition of the latent image.

How does the latent image become a true print image? Toner is a very critical role, the toner is essentially a charge of fine plastic particles, the charge and the drum on the surface of the opposite polarity of the charge, when the charge with the drum surface through the ink roller, the charge parts on the adsorption of toner particles, latent image becomes a real image. While the drum is rotating, another set of transmission systems feeds the printing paper with the same polarity but much stronger charge as the drum surface, and the paper passes through the toner cartridge with brother tn 660
on the drum surface is attracted To the top of the paper, the image is formed on the surface of the paper. At this point, the tn420
and the printer are only bound by the attraction of the charge, and the plastic toner is melted and heated to the surface of the paper during the cooling process before the printing paper is fed out of the printer.

After the toner is attached to the paper, the drum surface continues to rotate, passes through a cleaner, and removes the remaining toner in order to enter the next printing cycle. Visible, in this process the drum occupies a very important position.
In fact, the cartridge is the most critical component of the laser printer. Because it not only determines the quality of print quality, but also determines the printing costs. This is because in the laser printer, more than 70% of the imaging components are concentrated in the cartridge, the print quality is actually a good or bad in fact determined by the cartridge. And the cartridge is part of the printer consumables, the use of a certain period of time and to achieve a certain number of sheets need to be replaced.

Original supplies directly produced by printer manufacturers, supplies technology all by the printer brand R & D completed in the processing and production, testing process are strictly in accordance with the process to carry out, supplies have a certain quality requirements of the standard. Although the original price of the goods carrying the manufacturers of technology and market costs, but the current price is indeed high, which is a lot of users to abandon the original supplies to choose compatible supplies important reason. How to make users feel that the price is worth it? I am afraid that manufacturers need to reduce the price on the one hand, on the other hand or from the service point of view.

For the printer supplies market, the advantages of original supplies is very obvious. First of all, the original supplies of the general pool of the technical strength of the manufacturers, such as printers, complex machines need to consider the overall cost of office equipment, original supplies and machines have a perfect match, the printing process has better quality and stability; Original packaging components are also pay attention to the output effect is higher than the general compatible supplies. In the after-sales service, the original supplies completely after-sales system, if it is quality problems, users can enjoy the replacement of supplies services.

First of all, do not feel compatible with the original market to seize the goods, for the vast majority of consumers, the original high prices of brother tn 660, and the market of compatible supplies in the premise of low prices can meet the basic needs of users, so compatible supplies Become the vast majority of small and medium enterprises a low price election. In fact, consumers have this idea is also true, the original supplies prices higher than compatible supplies several times, access to the service is almost, as long as there is not much trouble, users use compatible consumables cost-effective.

The future of the original supplies manufacturers to stabilize the market, on the one hand to optimize the price system, we now see Kyocera launched 100,000 pages of toner cartridges / high-capacity supplies, brothers, HP introduced high-capacity ink, in the ink cartridges to reduce the purchase price, Capacity, to enhance the original supplies in the customer's influence.
