What Is The Toner Drum？

In the laser printer, more than 70% of the imaging components are concentrated in the toner, the quality of printing is actually largely determined by the high-quality toner. Good toner not only determines the quality of printing, but also determines the amount of money users need to spend in the process of use.

Selenium is a non-metallic chemical element with the chemical symbol Se. It can be used as photosensitive material, catalyst for electrolytic manganese industry, essential nutrient element for animals and beneficial nutrient element for plants, etc.
Good Toner Drum

The charcoal powder in the high quality toner drum is the key to imaging in the printing process, so what makes these charcoal powder finally form a document on the page? First we need to understand what a latent shadow is. A good toner is a surface coated with organic materials (selenium, a rare element) of the cylinder, with a charge in advance, when there is light exposure, the part of the radiation will occur resistance reaction. And the data signal sent to control the laser emission, scanning the light on the surface of the Toner Cartridge constantly changing, so that there will be some places by the irradiation, the resistance becomes small, the charge disappears, and some places are not irradiated by the light, still retain the charge, finally, the surface of the toner cartridge formed by the charge of the latent shadow.
High Quality Toner Drum

And high quality toner toner is a fine resin particles with charge, charge and charge on the surface of the toner toner on the opposite polarity, when the surface of the toner with charge through the ink roller, the charge of the part of the adsorption toner particles, so the latent shadow will become a real image. And when the toner drum in the work at the same time, the printing system will transmit the printer paper, and the printer paper with the same polarity as the surface of the toner but a lot of charge, then the paper through the toner drum, toner on the surface of the toner drum is attracted to the printer paper, the image is formed on the surface of the paper. At this point, the toner and the printer paper are only bound together by the attraction of electric charge. Before the printer paper is sent out of the printer, the toner is melted by high heat, and solidified on the surface of the paper during cooling. After the toner is attached to the printer paper, the surface of the toner continues to rotate, passing through a cleaner to remove the remaining toner, so that it can enter the next printing cycle and be reused.
