Every accessory of Printers or Copiers toner cartridges
Drum: It is a cylindrical object. In the laser printer, it refers to the cylindrical light conductor to distinguish it from the light guide plate and the light guide tape. The simplest drum is to install a gear Gear and a conductive sheet on both ends of the drum to make a complete single drum.
Photoreceptive Drum: It emphasizes the drum with light guiding properties and defines the drum. There are many types of photoconductive materials, such as selenium (Se) drums, cadmium sulfide (CdS) drums, silicon (Si) drums, and organic photoconductor drums.
Organic Photoconductor Drum/OPC Drum: Organic photoconductive materials come from a wide range of sources, are inexpensive, have superior performance, and are non-polluting. They have replaced other photoconducting materials in the past and become the unification of OPC drums.
Photorecepotor Cartridge/Imaging Unit: The photoconductor drum is used as the core, plus the charging roller, developing roller, cleaning blade and other components to form a static image that can be used to convert the static electricity generated by the photoelectric signal into a visible image. Device. Only the toner is consumed in the imaging assembly, and other parts are only fatigued or worn. When the toner is used up, the cassette has to be thrown away.
Drum Cartridge/Drum Unit/Drum Kit: Sometimes the imaging composition is drum level, such as HP, Canon series. Sometimes the anti-developing part is inseparable, leaving only the drum core, the charging roller, and the cleaning blade. This part is the drum component, such as the Epson and Lexmark series. What's more, even the developing roller is retained, there is no powder bin/powder, which is also called the drum assembly. This drum kit is not thrown away by the use of toner, just replace the developing unit, or even replace the toner cartridge, such as the drum series of the Brother series.
Developer Cartridge/TD Cartridge: There must be a developing roller in the developing unit that absorbs the toner and charges it to transfer the toner to the drum surface. The drum core, the charging roller, and the cleaning blade are never included in the developing assembly, but the toner cartridge is sometimes single.
Primary Charging Roller/PCR: A rubber roller made of a metal core roller, a foamed conductive rubber, and an outer insulating plastic sleeve. Both ends of the shaft are embedded in the conductive seat, and the charging roller is pressed tightly against the surface of the OPC drum by a spring. The OPC drum surface can be charged at a certain voltage. If the surface of the charging roller is scratched by foreign matter, the surface of the OPC drum will be unevenly charged or even short-circuited, and the print quality will be degraded and must be repaired or replaced.
Developer Roller: The function of the developer roller is to pick up the toner, charge it, and transfer it to the surface of the OPC drum to produce a visible image. Since the one-component toner also has a magnetic powder and a non-magnetic powder, the developing roller is also divided into a magnetic roller and a conductive roller.
Magnetic Roller/Mag Roller/MR: It consists of a magnetic core rod Magnet fixed inside and a Mag Roller Sleeve with an outer rotatable aluminum sleeve, and a plastic sleeve and a conductive spring at both ends. A rough layer of graphite is sprayed on the surface of the aluminum sleeve.
Development blade / magnetic roller scraper / magnetic scraper / powder scraper / small scraper (Doctor Blade): is an elastic plastic sheet that is injection molded or bonded to a metal plate.
The magnetic roller can be charged by the magnetic toner under the pressure of the squeegee. The magnetic roller absorbs the magnetic toner by the magnetic force, and the charged OPC drum absorbs the magnetic toner by the electric field force, and each of them exhibits its energy. The magnetic roller is covered with a wear-resistant insulating bushing Mag Roller Bushing, also known as a gap sleeve, to maintain a strict gap between the magnetic roller and the OPC drum (wall thickness of the bushing). The aluminum sleeve is energized and there is a “bias” between the OPC drum for “jump development”. The HP and Canon series use single-component magnetic powder, and magnetic roller development is patented.
The graphite layer on the magnetic roller sleeve will also wear under the squeegee and the toner, and the development performance will be deteriorated. At this time, the graphite layer needs to be recoated, and if the aluminum sleeve is damaged, it must be replaced unless the magnetic core is magnetic. It is only necessary to replace the refurbishing magnetic roller when it is weakened.
However, the one-component magnetic powder is not easily colored. Moreover, the magnetic powder has a short shelf life, so printers such as Epson and Lexmark use single-component non-magnetic powder. Its developing roller is a charging roller that energizes the public powder and sucks the toner onto the surface of the OPC drum. The developing blade is made of a metal strip Blade Bar, which is also called a uniform blade. It is connected to an alternating voltage, so that the toner on the developing roller is beaten and evenly distributed.
Drum Cleaning Blade/Wiper Blade/Cleaning Blade: Unlike the magnetic plate, it is not frictionally charged with the side of the strip and the cylindrical busbar of the magnetic roller. Instead, the sharp edge of the end face of the strip is tangent to the cylindrical bus of the OPC drum, so that the residual powder remaining after the surface of the drum is scraped off, so the metal plate and the plastic strip of the cleaning blade are thicker and harder. The strip edge is more prone to wear and often needs to be replaced.
Recovery Blade: It is the drum scraper. In the imaging assembly, the part where the drum is located (including the OPC drum, the charging roller, the scraper) is called the "waste powder bin" Wastc Bin, and the portion of the developing roller and the toner is called the "powder bin" Toner Hopper.
Cleaning Brush/Electrical Brush: For Epson series drums that use one-component non-magnetic powder, it is often not necessary to clean the squeegee and only use a cleaning brush. Because the transfer rate of the non-magnetic powder is extremely high, almost all of the toner image on the drum is transferred to the paper, and there are very few residual powders left on the drum. It is only necessary to eliminate electricity, powder, and even drums. There are no waste toner bins in the assembly.
Transfer Roller: Similar to the structure switch of the charging roller, except that it has conductive rubber and different insulation layers on the surface. Because it simply charges the paper, the toner image on the surface of the OPC drum is transferred to the paper. The transfer roller does not belong to the imaging assembly, but to the components on the complete machine.
Counter/Chip Chip: The counter is a simple memory tool that helps users understand the life of consumables. However, in order to protect the profit of more consumables after the sale of their machines, the whole machine took the trouble to put the memory chip OPC Drum Chips/Toner Cartrldgr W/chips on the drum components and powder components, using the latest encryption technology to make the recycling plant Or the user can't work even if a new drum is replaced and a new powder is added. Some of the chips are non-rewriteable, and the original manufacturers that provided the chips signed a blockade contract with the whole machine factory, and applied for patent protection. In order to make a chip, in addition to the technology, the cost is a big problem, which causes a time difference for the production of compatible consumables.
