Many copier require carbon powder on the market, but the carbon powder market more birds pay homage to the king, but because the birds too much, you are hard to see what a phoenix. 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. How are you going to choose ( 轩泽) The carbon powder? This link but will have an impact on the copier ( 影响) 。 If the quality of carbon powder, its effect is not better copy. 1) Fine precision: various carbon powder 300 - are considered 1200 dpi laser marking machine; 2) Blackness: plate type carbon powder, special black ancestral secret recipe, improved the toner particles blackness; 3) Electrical equipment: plate type of toner particles by induction electrical price generally practical powder high, maintain positive performance is strong, make carbon powder can be more abundant transfer paper to the paper, greatly reducing the residual powder; 4) Dry solid power: carbon powder in the chemical material such as transfer paper copy paper and board have good adhesive power; 5) Fixing temperature ( 温度) : according to different specifications of design with the fixing temperature, melting, solidification, inside short time fixing effect is better, and non-stick upper fuser roller, fuser film, or using extraction can easily get the pieces of paper, reduce the paper card and thus to minimize damage to related prefabricated; 6) Small friction index value, especially fine particulate matter carbon powder to maximize reduce friction with the drum level, can delay the service life of the photosensitive drum, another scraper clear the residual powder is easy to clean and tidy. 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. 2, the harm of carbon powder on the copy ( wēi hài) 1) Carbon powder, the quality is not good in the use of moisture and temperature change is big in the natural environment, sit idle time longer, can lead to ( 原因) Agglomerate, when using the process of carbon powder compact prefabricated harm ( wēi hài) , thus damage development quality, and can reduce the service life of carbon powder compact. 2) On the basis of upper fuser roller (copy gǔn) For carbon powder to heat up, is conducive to the carbon powder melting ( Definition: the changing process of substances from solid to liquid) Embedded into the paper, after wide carbon powder melting point level, high quality with the characteristics of different copy of upper fuser roller to cooperate with each other, in a different copy above to get high quality print quality. 3) Narrow carbon powder melting point level, print quality is not stable, Explanation: solid stability; There is no change) When carbon powder melting point higher than upper fuser roller heating air relative humidity, the carbon powder melting is not enough, can't completely immerses papier-mache synthetic fiber, cause image of fixing firmly; And when the carbon powder melting point is lower than the upper fuser roller heating temperature, carbon powder a variety of soft, stick on the upper fuser roller, fuser roller, air pollution easy ceng dirty copy paper. Color toner in print, volatile due to residual monomer in the resin is heated, produces the pungent odor, therefore national standards and industry standards of toner TVOC has carried on the strict limits. So as long as you buy printer or nonconforming product quality, won't because printing produces gas harmful to health.
