How Toner Cartridge Works
- Sep 13, 2016 -

The toner in the print cartridge is the key to imaging during the printing process, so what makes these charcoal powders eventually form documents on the page? First we need to know what a latent shadow is. A toner cartridge is a cylinder coated with organic material (selenium, a rare elements) that is preceded by an electric charge, and when light is irradiated, a resistance reaction occurs in the exposed area.

The sent data signal controls the launch of the laser, scanning the light on the surface of the print cartridge constantly changing, so that some places will be irradiated, the resistance becomes smaller, the charge disappears, and some places are not exposed to light, still retain the charge, and eventually, the surface of the print cartridge forms a latent shadow composed of the charge. The toner in the print cartridge is a fine, electrically charged resin particle, which is the opposite of the charge polarity on the surface of the print cartridge, and when the surface of the cartridge with an electric charge passes through the ink-coated roller, the charged part absorbs the ink powder particles, thus turning the latent shadow into a real image. While the print cartridge rotates at work, the printing system transmits the paper, and the paper is charged with the same polarity but much stronger as the surface of the print cartridge, and then the paper passes through the toner cartridge, the toner on the print cartridge surface is drawn to the paper, and the image is formed on the surface of the paper. At this point, toner and paper are simply combined by the attraction of the charge, before the paper is sent out of the printer, after high temperature heating, toner is melted, curing in the cooling process on the surface of the paper. After attaching the toner to the paper, the surface of the print cartridge continues to rotate, passing through a cleaner and removing the remaining toner in order to enter the next print cycle.
