The toner cartridge, also known as the sensor, is generally composed of the basic substrate made of aluminum, and the sensitivity material coated with the substrate.What is the working principle of toner cartridge?How to buy the toner cartridge? Lets take a look at the editor below!
Chronin working principle
The carbon powder in the toner cartridge is the key to imaging during the printing process, so what makes these charcoal powder finally form a document on the page?First of all, we need to understand what is called Qianying.Chronom is a cylinder with organic materials (selenium, a rare element) coated on the surface. It has a charge in advance. When the light is irradiated, a resistor reaction will occur.The data signal sent by the sending controls the laser transmission, and the light scanning on the surface of the toner cartridge is constantly changing. In this way, some places will be illuminated, the resistance becomes small, the charge disappears, and there are no light irradiated in some places.In the end, the surface of the toner cartridge forms a submarine shadow composed of charge.
The carbon powder in the toner cartridge is a kind of fine resin particles with charge. The charges of carbon powder are the opposite of the charges on the surface of the toner cartridge. When the surface with a charge of selenium is applied to the ink roller, the charged part is adsorbed on the ink powder.Granules, so the subtes turned into real images.
How to buy toner
Roughly packed
The original toner cartridge is exquisitely printed with exquisite quality and bright colors.The printing quality of counterfeit products is rough, the image is blurred, the color is dark, and there are traces of strong imitation on the packaging, and some do not match the inside and outside.
Look at the connection carefully
Use the old original drums to self -pouring powder to pretend to be a new drum sales. If there is a signs of "rushing" or the hair blue layer of the screw (that is, the black thermal treatment layer) is destroyed, it is likely to be a rebate.
Scanning surface
The surface of the chronological drums after the self -pouring powder is rough, with obvious scratches. The amount of scratches is proportional to the frequency of the selenium. It is impossible for the original new drum to have any scratches.
testing on the spot
The image and text printed by the new original toner cartridge are not only delicate and clear, but the drum powder of the original toner cartridge is particularly good. Printing on the paper carefully looks at the feeling of highlighting the paper surface.
Basic structure of toner cartridge
The basic structure of the toner cartridge is generally composed of the basic substrates made of aluminum, as well as the sensitive material coated with the substrate.According to the different sensitivity materials, it can be divided into three types: OPC drums (organic light guide materials), selenium (SE selenium) and ceramic drums (A-SI ceramics).
1. From the perspective of life, the life of OPC drums is relatively short, generally only about 3000 pages, and of course the price is the cheapest.The SE drum life is about 9000 pages, and the A-SI drum life can reach 90,000 pages. The price is naturally rising in order.
2. In terms of composition, there are only three layers of OPC drums.The first layer is an aluminum tube, the second layer is the insulation layer, and the third layer is the sensitive layer.The surface of the toner cartridge (SE selenium) and ceramic drums (A-SI ceramics) is synthesized by four to five layers of substances.Especially for ceramic drums, the fourth layer is the first protective layer, the fifth layer is the second protection layer, and the fourth and fifth layers are used to protect the sensor layer to ensure the long life of the toner cartridge.
