Like we know, printer cartridge is a kind of important printing supplies. In order to save the cost, some people will buy cheap toner cartridges, we can not say it must a wrong choice. But we need to know these below points.Printing / copying supplies is a consumable, from time to time for a new batch of supplies, the purchase of supplies also need to have some skills, in case of poor supplies to buy will affect the normal work in the future, Therefore, material selection must be cautious. The following will introduce five tips for purchasing supplies for your reference.

First, see the effect. The printing effect is undoubtedly an important measure of a print / copy supplies. Copier effect is to see the text image resolution, whether distortion, contrast is large. The original print supplies in the printer supplies printing no doubt the best, but now there are many universal consumables manufacturer's technology has reached international standards, the production of supplies in the printing effect and the original supplies is not much difference.

Second, look at the quality. This includes whether the cartridge leaks ink, toner cartridges will leak or print the end of ash and so on. Because sometimes there may be no problem with the printing effect of the product, but may be cast after long-term use of color, print files appear disconnected and so on. This is some inferior generic printer supplies or fake consumables, easily lead to plug the print head, print quality problems such as the decline, the serious will lead to print head damage, so that the equipment scrapped, so that users are worth the candle.

Third, look at the price. Consumables prices have been the subject of user concern, after all, often need to buy supplies, supplies directly determine the level of the cost of how much later. In the printing supplies price, the original supplies expensive, but the print quality is good, the effect is guaranteed; general supplies in the price there is no certain industry standards, the price varies. Photocopier copy faster, more features, the higher the price of copiers, followed by more expensive supplies and accessories.

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.
