Toner is the blood flowing in the toner cartridge. The quality of the toner is not only related to the final print quality but also related to environmental protection and health.

From early physical grinding of toner to the introduction of chemically formulated toners in 1998 to precision black toner/ECO smart toners, HP continues to innovate to provide users with better print quality.

So, what is the difference between traditional physical toner and chemical toner? What are the advantages of chemical toner?

Black toner type

The conventional physical toner is a bulk carbon powder or a powdery carbon powder, which is obtained by mixing additives such as a resin and a pigment and is then ground.

Chemical carbon powder, which is a polymerized carbon powder, is a mixture of single-molecule objects, pigments, and other additives. The chemical polymerization method controls the size, shape, and structure of the toner particles better.

Black toner treatment

The conventional physical toner is roughly mixed with solid resin, a magnetic material, a pigment, a charge control agent, a wax, and the like, and then heated in a machine to melt the resin. At the same time, the components that cannot be melted are uniformly dispersed into the resin, and after cooling and solidification, coarse pulverization and classification (separation of too coarse and too fine particles are separated), and then some nano-powder is wrapped outside the particles to enhance the flow and adjust the dispersion. Electrical performance.

The chemical carbon powder is obtained by adding pigment, a charge control machine, wax and other components to a liquid organic monomer, and at a certain temperature, the monomer is polymerized into the resin by an initiator, and at the same time, a component containing each component is formed. Particles. Finally, the toner particles are washed and dried.

Chemical toner advantage

The difference in production processes makes a difference between traditional physical toner and chemical toner.

The chemical carbon powder particles are spherical and nearly uniform in size, so the fluidity is better than the physical carbon powder, and the printing utilization rate is higher.

The content of each component in the chemical carbon powder is nearly uniform and uniform. However, when the physical toner is too small, the problem of uneven dispersion occurs.

The chemical toner has a more uniform particle size distribution. Physical toner particles vary in size and distribution, and the printed documents may have blurred edges and burrs. The size of the chemical toner particles is nearly uniform, spherical, uniform in particle size distribution, and the printed document is clear and sharp.

HP black toner continues to improve

From early physical grinding of toner to the first chemically formulated toner in 1998 to precision black toner/ECO smart toner, HP continues to improve toner technology to deliver outstanding print quality, consistency, and reliability.

HP Original Black Toner is divided into physically generated abrasive toners and chemically produced toners. No matter which technology is used, the toner particles are small and the print quality is stable.

Non-original toners are mostly produced by physical grinding. The cost of toner is low and the toner particles are not uniform. The shape is irregular. Therefore, the toner utilization rate is low, and the printed documents are not as clear and delicate as the original toner.
