Toner drum also known as drum, generally made of aluminum substrate and substrate coated with light materials. In the laser printer, the toner cartridge set more than 70% of the imaging components, directly affects the quality of printing, is the most critical part of the laser printer. The toner cartridge is the heart of a laser printer. It not only determines the quality of printing, but also determines the cost of printing. So understanding the toner cartridge side of the laser printer use is very important. Today, the printer toner unit manufacturer, for you to discuss the printer toner unit structure is composed of what: First of all, different brands or use of the printer, the structure of the toner cartridge and its classification will be different, the general toner (one unit) will basically include the following components, and split toner (also known as separate drum powder cartridge) is only the following parts of the components. Drum core: through the aluminum tube surface coated with photoconductive semiconductor material, is the heart of the toner cartridge, other components to its center. After charging, exposure and development, the surface forms visible toner image. Toner: is directly melted on the printing medium of the attachment, different types of toner can not be used. Powder bin: a warehouse for storing toner, some of which contain a mixer to ensure the smooth supply of toner. Powder bin: a warehouse used to hold waste powder. The toner image formed on the surface of the photosensitive drum cannot be 100% transferred to the printing medium. It will remain on the surface of the photosensitive drum. Clean scraper: against the drum, the drum surface is not transferred on the residual carbon powder clean, clean scraper is composed of a metal frame and polyurethane scraper. Powder knife: composed of metal frame and polyester scraper. It uniformly controls the amount of carbon powder on the surface of the magnetic rod and electrifies the carbon powder by friction. Charging roller: eliminates the residual potential on the drum and is responsible for the cylinder composed of a metal shaft and conductive rubber. Magnetic roller: composed of magnetic core, magnetic sleeve and accessories. In the development process, it attracts the carbon powder to its surface, and under the control of the powder producing knife, forms a specific thickness of the carbon powder layer, and makes the carbon powder carry a certain amount of friction charge. The development bias on the magnetic roller makes the charged toner "jump". Transfer roll: the transfer roll is located on the other side of the printing paper, because it is applied to the toner and the electricity of the opposite voltage, so that the toner drum to the paper. Development roller: a metal shaft and conductive rubber, its role is to adsorb carbon powder, so that it is charged, and transmitted to the surface of the drum, to produce visible images. The original toner cartridge color is a grayish blue or light brown, toner in the toner cartridge is black, but if it is a color laser printer toner color is red, yellow and blue, according to their different ratio deployment, constitute a kaleidokalic rich color. Toner drum shape is a cylinder, the basic substrate is aluminum, on the substrate coated with light-sensitive materials. |
