toner cartridge are common consumables for consumable printers. Toner cartridge manufacturers have designed one-off consumables for some reasons. After a period of use, they need to be replaced. However, due to the relatively high price, many customers choose cheaper consumables, thus attracting a lot of businesses just around the corner Fake, so the market can not avoid the emergence of a wide range of fakes. Whether it is in the economy or work have given people a lot of damage, then how to avoid buying fake it? V4ink consumables below for your analysis:

1, look at the packaging; authentic cartridge packaging printing more sophisticated, and the back of the serial number is very clear, such as hp toner cartridges are generally on the side of the packaging box affixed a security label, when we look at it from different angles will find its color will change between black and blue. The poor quality of counterfeit printing products, dark colors, the image is rather vague.
 
2, look at the drum; drum cartridge drum color is dark blue or light brown, and fake cartridge drum color is bright green or blue; drum drum surface smooth degree of high, without any scratches , while some fake toner cartridge drum surface roughness, there are obvious scratches.
 
3, look at the price; if we buy cartridges when the offer is very cheap, then you have to be careful at this time, because at present, the general original cartridge price is still high, if you encounter more than the normal low price of the most cartridge Good or not to buy. Some people may say that due to the purchase of different channels or for any reason the price is very cheap, although we do not rule out the existence of this situation, but in this case we'd better still think twice before, after all, the sky will not fall Pie.

4, do not superstitious gifts; really print cartridge sometimes with promotional gifts.
 
5, to see if the screws are lacquered; fake toner cartridges are generally generated by the old cartridge re-add toner, after a simple renovation process, so sometimes you can still find loopholes. If the cartridge disassembly screws, if there is no traces of paint, it is most likely fake.

Many people are suggesting to protect our earth through recycling those things which can be reused. About those waste toner cartridges, we also need to recycle them, and we must know if use cheap toner cartridges, which have not longer life, it means make more waste for the earth.

The steady growth of modern office equipment has also brought with the matching ink cartridges, toner cartridge and other supplies to 30% annual rate of increase. And these non-degradable supplies, as garbage disposal is not only a waste of resources, but also increasingly threatening people's living environment. From Table 1, it can be concluded that the output of the laser supplies market in China has increased year by year, the growth rate of the whole toner cartridge components is about 9%, and the growth rate of the recycled toner cartridges is about 40%. Based on this growth rate, it is expected that by 2009 the amount of waste toner cartridge will exceed the new toner cartridge, usually 10-20% of the weight of the waste toner cartridge. Plastic accounts for about 18% of the weight of the exhaust gas cartridge. In the waste toner cartridges, the greater harm to the human body is the toner. The main ingredient in toner carbon black has carcinogenic effects, it has been the International Cancer Research Organization (IARC) included in the list of carcinogens. If the recovery and re-use of solid waste such as cartridges can not be conducive to the environment and conducive to conservation purposes, then the pollution caused by them will not be overlooked.

The composition of the cartridge After the initial dismantling of the drum can be a photosensitive drum, plastic cover, gear, magnetic coats, magnetic rods, plastic rings, scraper, shaft, screws, springs, pins and plastic shell (including powder and waste Warehouse) and other components. The material composition of the cartridge includes plastic, iron, magnetic, aluminum, copper, soft material and toner. 2.2 The composition of toner composition Toner is made of resin, carbon black, magnetic oxide, lubricants and other materials synthesis of a mixture (see Figure 1), at room temperature is more stable, the surface size is relatively uniform fine particles, Light weight, difficult to dissolve in water, chemical stability. By scanning electron microscopy (SEM) magnification observation, you can more clearly see that the toner particle size is more uniform, spherical particles, particle size between about 3-7μm.
