Buy the copier carbon ( C) Powder, believe that many people would consider its blackness values, for the graces is the higher the blackness values of carbon powder is better? First of all, we need to know what blackness values, the blackness of value is that it is by calculating blackness values tester to launch a number of strong beam, beam to graphics under test, black degree value is reflected back to tester, be absorbed beam calculation, through a fixed ( 固定的) It is concluded that the value of the calculation program. Because laser ( LASER) Printer is designed mainly for office, so, it's OEM blackness values on average at about 1. Carbon powder polymerization toner used widely, because of the high cost, mainly used in the production of color toner. About 48. While some types of printer at home, to the film or sulfur ( Chemical symbol: S) Acid paper to print media, such as the print medium fiber with special chemical treatment, relatively common printing paper, resin in the carbon powder is more difficult to melt ( Definition: the changing process of substances from solid to liquid) Infiltrate the paper fibers, so the baby to the requirement of carbon powder. In selenium ( 硒) Drum state conditions, many of the compatible consumables vendors carbon powder can meet this requirement, the average values of blackness in 1. The 50 or so. General users will believe print on the black on the surface of carbon powder, the better, but sometimes other factors carbon powder ( 因素) Can also cause this illusion. For example: fixed on degree of carbon powder is poorer, only adsorbed on the surface of paper, and not fully penetrating ( 渗透) Into the paper fibers, at that time most of the accumulation of carbon particles in the paper surface, for the light absorption rate is very high, feeling giving a person is very black, which is why some users said print proof need not see, touch the can know the reason why the black is not black. But the truth, 事实) , high melting point of this carbon powder, print the words is not strong, is not a good carbon powder. There are, of course, is not to say that the higher the blackness values, the better, if too high will product negative effect, is a certain amount of carbon powder, under a certain average coverage, the printed page relative to reduce, increase the cost. Color is used in the paper in the laser printer toner fixing powder material. Black toner by bonding resin, carbon black, electronic agents, additives such as ingredients. Still need to add other color in the color toner pigment, etc. Printer toner many drums in original toner after use, the user can add after used again, so also is to have separate toner for sale on the market. By adding toner by oneself, will reduce the use of the user supplies cost.
