Component Composition of Laser Printer Toner Cartridge

There are several parts of toner cartridge compositions that your maybe not known, now let us go into the toner cartridge inner world to have a see.
Let me take Brother HL-2240D printers as an example. With the important crucial part, toner 420 is largely determined the printing quality, which is a typical separation toner cartridge.
OPC
The full name of OPC is organic photoconductor drum, which organic photoconductive materials have a wide range of resources, the performance is superior and pollution-free. In terms of life expectancy, the OPC drum has a shorter life with generally only about 3000 pages, and of course the price is cheaper.er
Developer Roller
The function of develop roller is the adsorption color toner to electrified it, then sent to the drum surface of OPC and produce generate visual images. Because the single group of color toner also has magnetic roller and non-magnetic toner, the development roller also has magnetic roller and conductive roller different names.
Photoreceptive Drum
It more emphasized that the drum has photoconductive properties, and characterize the drum. There are many kinds of photoconductive materials, including selenium、cadmium sulfide、drum and silicon and organic light guide drum and so on.
Drum Unit
Drum Kit refers to the light-sensitive part of the toner cartridge, including drum core, powder scraper and so on. Sometimes the anti-development part is not inseparable, only the drum core, charging roller, cleaning scraper, this part is the drum component for Epson, Lexmark series. What's more, even the rollers are preserved, but there is no powder storage/powder drum, which is also called drum unit. The drum unit is not to be thrown away for the toner finished. You just replace the developing component and even replace the powder tubes. Brother brand is representative about this aspect, and among that brother dr420 drum is a typical instance.
Primary Charging Roller
It is made of metal core roller, foam conductive rubber, and rubber roller made of plastic wrap. The two ends of the shaft are embedded in the conductive seat, which is pressed against the surface of OPC drum surface. The OPC drum can be charged at a certain voltage. If the surface of the charging roller is scratched by a foreign body, it will make the surface of the charge of the OPC of the OPC drum not even, or even short circuit, and the printer will produce profile with poor quality , it's time for you to repair or replace it at once.
MR
Magnetic roller is the Magnetic Roller's abbreviation. It consists of a magnetic core magnet which is fixed in the inside and a rotating aluminum sleeve, and two ends of plastic sleeve and conductive spring. A rough graphite layer is sprayed on the aluminum sleeve surface.
TR
Similar to the structure switch of the charging roller, but TR (transfer roller) conductive rubber, the surface insulation layer is also different. Because it's just charging the paper, the color image on the surface of the OPC drum transferred to the paper. The transfer roller is not belonging to the imaging component, but the parts of the whole machine.
These component composition of toner cartridges are commonly used, and it's better for you to know more detail about a printer, which it's good for you to have plan in mind when you about to buy a laser printer.

Some major parameters and Brands that student should pay attention to when choosing a printer

With the study life begins in September, more student may worried about how to choose a printer that is economical and affordable in a variety of different types of printers for their study printing? Maybe you can consider from the following aspects.
1. Resolution: the printer is also called the output resolution which refers to how much print points per inch on the horizontal and vertical directions when you printing, usually it said that "points/inch" DPI (dot per inch). For example, 1440x720dpi means that the horizontal resolution of the printer is 1440dpi while the vertical resolution is 720dpi. When choosing a printer, we should focus on the horizontal resolution as well as the vertical resolution. As to student users, the resolution cannot be less than 600dpi and the resolution of pictures should be no less than 1440x720dpi.
2. The droplet size. Droplet size is a vital index to measure the degree of fine print, slightly rises is widely used to measure the size of the unit volume of ink jet printing ink(PL), the user need to print photographs should choose printing device within the 4pl of drops size.
3.Brand features : now there three big brands in the field of printer which are brother ,HP and Canon , the three manufacturers of printing technology is relatively mature and have a good print effect.
HP
HP printers use hot ink jet technology and adopt the integration structure of print head and toner cartridge. When you change the toner cartridge you also need to exchange the print head. As you can see the most important feature of this structure is the high cost of ink. But HP printers generally have better quality of printed text, such as HP cf210a toner cartridge, at the same time it has led to the rapid development of the toner market and other consumables.
Brother
Brother's product line is a single one, with the A4 size medium and low speed printer, which rarely involves the A3 format printer. Brother's printer can realize automatic double-sided printing on the printer below 30ppm, so it's a better choice for many small and medium-sized office enterprises. The color printer of Brother USES LED technology, and the speed of the printer is concentrated at about 20~35PPM, such as HP laser jet Pro M251 with more high-yield cf210x toner cartridge. In this case, the structure of the four-component drum component is adopted for TN210/221, which is suitable for many enterprise users.

Canon
Canon inkjet printer is also adopting inkjet technology. Canon does the best well in the paper. Many machines use double-feed system, namely paper box and paper. The overall printing speed of Canon inkjet printers is faster than those of the other two manufacturers, especially the seed of photo printing.
These are the most important aspects that students should pay attention to when choosing a printing device. Also I want to stress that is you should buy a printer according to the needs of yourselves and don't be a parrot. If you do don't know which one to buy, make a list about the function of printers and then carefully screen to select the most suitable printer model.
