How to choose printer toner powder? All strategies for selecting toner for laser printers: Understand types and characteristics, optimize printing effects.
- Introduction to laser printer toner
Toner powder, a crucial component in laser printers, is responsible for forming clear, fixed images on paper. This powdery substance is refined from a variety of ingredients, including binding resin, carbon black, charge control agent and external additives. Especially in color printing, the toner also needs to be incorporated into pigments of other colors.
It is worth noting that during the printing process, the monomers in the resin may produce a pungent odor, but as long as a qualified printer or toner cartridge that meets national standards and industry specifications are selected, this odor will not cause any harm to health.
- How to choose laser printer toner?
Choosing a laser printer toner is not easy, but understanding the different types and characteristics allows you to make informed decisions. While some types of toner may be versatile under certain conditions, caution is required when choosing.
The charge amount of toner is also a key factor affecting image quality, but the charge amount of toner on the market is not much different, so it can basically be generalized. In addition, the softening temperature of the resin is also a factor that needs to be considered, especially for high-speed printers, which requires the softening temperature of the toner to be low, usually around 100 degrees. After understanding this information, you should be able to deal with it more calmly when replacing the toner.
- Toner powder type and application
On the market, toner powder is mainly divided into four types: negative electromagnetic, negative non-magnetic, positive electromagnetic and positive non-magnetic.
1.Negative Electromagnetic Toner
Negative electromagnetic toner, because it contains soft magnetic materials (mostly iron tetroxide), is negatively charged under the friction of the powder knife (or scraper). This type of toner is widely used in most laser printers of brands such as HP and Canon.
It is worth noting that although it is not magnetic in itself, it can be effectively attracted in a magnetic field, such as the magnetic roller in the toner cartridge. Therefore, it is also suitable for magnetic roller-free laser printers such as Samsung, Epson, and Lexmark, but it is necessary to ensure that its particles have good shape and meet the standards of particle size distribution.
2.Negatively charged non-magnetic toner
Negatively charged non-magnetic toner, does not contain soft magnetic materials, and is negatively charged after friction. This type of toner is only suitable for laser printers without magnetic rollers such as Samsung, Lexmark, and Epson, as well as models equipped with negative electric powder.
However, it should be noted that it cannot be used for laser printers equipped with negative electric powder but with magnetic rollers, such as HP and Canon. It cannot be used for models equipped with positive electric powder such as Brother.
3.Positive electromagnetic toner
Positive electromagnetic toner, which contains soft magnetic material, is brought with positive electricity after friction. This type of toner is mainly suitable for analog copiers such as NP1215 that use positive electropowder (it should be noted that laser printers usually do not use positive electromagnetic toner).
In addition, it can also be used in models such as Brother that are equipped with positive electric non-magnetic powder. But be sure to avoid using it for printers equipped with negative electric powder such as Canon, HP, Samsung, Lexmark, and Epson.
4.Positive non-magnetic toner
Positively charged non-magnetic toner, which does not contain soft magnetic material, is positively charged by friction. This type of toner is only suitable for specific models such as Brother and Lenovo 2312, which are equipped with a copying system specially designed for positive powder.
It should be noted that positive-electric non-magnetic toner cannot be used in any printer using magnetic or negative-electric powder. This characteristic shows that in the selection of printer consumables, positive and negative powder have a clear distinction and cannot be mixed. Meanwhile, although magnetic powder may be able to replace non-magnetic powder with the same electrical properties in some cases, non-magnetic powder cannot replace magnetic powder, which is determined by the fundamental differences in physical and chemical properties between the two.
