Surface charge to attract toner into a visible toner image developing roller: also known as the developer magnetic roller, magnetic stirring toner toner negative charge conductive / insulating plastic: card on both sides of the charging roller, white insulation, black conductive sleeve: also known as the developer roller sleeve in developing magnetic roll two. Bunker: storage of printer toner. Cleaning system role: the residual power and the residual powder on the clean drum include: cleaning squeegee / scraper: a rubber and iron, is to clean the drum surface, the residual powder waste bunker: store the printer Feifen eliminate electrical sawtooth residual power of the piece: clean drum, from the discharge effect. The role of fixing the system: so that the toner by heating curing the paper fixing institutions in two ways: fuser film fuser and fuser roller fixing. So that green laser pointer becomes more and more practical and better and better received by the customers.
Paper system role: to feed the paper include: pickup roller: one with a corrugated rubber wheel, is to rely on friction of paper into the print area paging: one with a flexible rubber skin within the specified time, rely on friction to make the leaflets paper damping plate: consisting of an iron and rubber, the role of the paper help to the pickup roller and the pager relay: coil winding, the role is to control the pickup roller Turn the paper detection sensor: a light-emitting diode and a phototransistor, the role is to check whether the printer paper feed sensor: the role of paper is detected, the print area is within the specified time to reach the paper sensor. For example, the 2 in 1 laser pointer has the laser function and ballpoint function.
The role is to detect paper within the specified time to reach India district. A good laser printer is the most critical component is the cartridge, also known as a drum. It not only determines the print quality is good or bad, and also decided how much of the money spent by the user during use. Laser printers, more than 70% of the imaging components are concentrated in the print cartridge, print quality is good or bad in fact is largely determined by the cartridge. Cartridge model refers to the model of which the printer can use the cartridge, under normal circumstances, use the match with the printer cartridge model recommended by the manufacturer, different models of secondary fill use, otherwise you can not use. Cartridge basic structure is generally composed of aluminum into the substrate, and substrates coated with photosensitive material. And at the same time the laser function of green laser can be applied.
Depending on the photosensitive material, the basic can be divided into three types: OPC drum (organic photoconductive materials), cartridge (Se Se) and ceramic drum (a-si, ceramic). Life point of view, the shorter the life of the OPC drum, usually only around 3000, and of course the price is the cheapest. Se drum life is about 9000, a-si drum life can reach 90 000, naturally, and so the price rise. The toner cartridges have integral (or integrated) and separation of two kinds. Integrated cartridge designed primarily toner cartridge and drum mounted on the same device would have scrapped the entire cartridge when the toner is exhausted or the drum is damaged. This kind of usa green laser pointer can be used as the elastic teaching pointer and ballpoint.
Models of this type of cartridge, HP (HP) and Canon (Canon) models, this unique design to increase the user's printing costs, and the hazards of environmental pollution, gave the manufacturer the a huge profit. Separate toner cartridge and drum set on a different device, and the drum's life is very long, are generally able to print 20,000 copies life. Simply put consume toner on the line, so that the user's printing costs decreased dramatically. This cartridge, Matsushita (Panasonic), Epson (Epson). From the composition, only three OPC drum. The first layer is the aluminum tubes, the second layer is the insulating layer, third layer is the photosensitive layer. The second generation green laser pointer has the extra function of remotely controlling the computer.
