toner and cartridge reset printer cartridge
Toner and cartridge manufacturer describe the structure of a toner cartridge
The cartridge is the core of a laser printer. It not only determines the quality of the print, but also determines the cost of printing. So it is important to understand all aspects of the cartridge.
Toner cartridges, also known as photoconductive drums, are the core components of laser printers. They integrate more than 70% of the imaging components in the printer, so it directly affects the quality of printing. It is said that when the cartridge was just developed, it used an inorganic material - selenium to make a photosensitive drum, so this is called. Today's cartridges have been made using organic photoconductive materials, which reduces costs and reduces pollution.
The color of the original toner cartridge is dull blue or light brown, and the toner in the cartridge is black, but if it is a color laser printer, the color of the toner is red, yellow, and blue, depending on the ratio. Columns are deployed to create ever-changing colors. The shape of the cartridge is a cylinder, and the basic substrate is aluminum, composed of photosensitive materials coated on the substrate. At present, the division of the toner cartridge is mainly distinguished from the photosensitive material and can be generally divided into three types: an OPC drum (organic photoconductive material), a toner cartridge (Se selenium), and a ceramic drum (a-si ceramic). In general, the OPC drum has a shorter life and the cheapest price. The drum has a long life, and the ceramic drum has the longest life, and the price is higher than others. General OPC cartridges consist of only three layers. The first layer is an aluminum tube, the second layer is an insulating layer, and the third layer is a photosensitive layer. The surface of the toner cartridge (Se selenium) and ceramic drum (a-si ceramic) is synthesized from four to five layers of material. Especially the ceramic drum, its fourth and fifth layers are used to protect the photosensitive layer.
