Copier toner is the main material of the machine, so it is very important for the copier, because the data need to copy machine in the office is more, so need to use the copy machine is more the amount of carbon powder. But in the choose and buy of copier toner is also a headache thing, because carbon powder on the market at present are of variable quality, very user even more sellers are difficult to make an accurate identification, and carbon powder quality copy has direct influence to the quality of equipment, will also damage the copier parts. So we should how to choose and buy the copier toner? What standards have to distinguish? Let small make up to you about today. 1, appearance: standard copier toner is black without impurities, no condensation ( 冷凝) Block. Carbon powder polymerization is a kind of fine chemical toner technology, it includes suspension polymerization, emulsion polymerization, detail capsule, dispersion polymerization, compression polymerization, chemical pieces. If discover the copier toner contains impurities, mainly made of recycling of waste powder which is fake product. Coagulum is generally carbon powder moisture characteristic is bad, or improper storage can cause this phenomenon. If 2, bouquet: standard carbon ( C) Powder basically is no smell or microstrip fragrant smell, especially import the copier toner gas will have fragrant smell. But the smell of homemade powder most serious with tar, so in use will have a lot of peculiar smell, very bad. 3, liquidity: if it is a standard of copier toner liquidity is very good, so I can take 20 g powdered carbon in white paper and then the rocking back and forth, so watch out of its liquidity is good or bad, because the copier toner will influence liquidity ( 影响) To powder blackness, bottom ash, transfer rate, etc. Printer toner according to different requirements, the carbon powder production to develop in the direction of refinement, color and high speed. Carbon powder manufacturing mainly adopts FenSuiFa and polymerization. 4, with power: the copier carbon ( C) Powder friction charged is key of the development process, and the electricity because the toner on a photoconductive surface selectively deposit is by electrostatic ( Is a kind of in the stationary state of charge) To control ( 控制) , positive and negative polarity and size of toner charged for printing quality control is an important parameter. Carbon powder polymerization is a kind of fine chemical toner technology, it includes suspension polymerization, emulsion polymerization, detail capsule, dispersion polymerization, compression polymerization, chemical pieces. Toner charged amount of each kind of model is different, but good quality toner the main charge is good stability, and power ascension can be stable and fast. 5, pollution of the machine: good quality toner should be in the process of the machine clean, good quality imported powder are generally free from contamination, and usually domestic powder on the drum core, charge roller, transfer roller, optical part has the heavy pollution, the life of the machine is greatly reduced, 一生) 。 6, stability ( 的稳定性) A: good quality carbon ( C) Powder, stability good carbon powder on the quality of the copy machine is very important.
