Toner Cartridge

A toner cartridge is a consumable component used in laser printers and photocopiers. It contains a fine powder called toner, which is a mixture of plastic particles and coloring agents. When a document is printed, the toner is transferred onto the paper using an electrostatic process and then fused onto the paper with heat. Toner cartridges are designed to be easily replaceable when they run out of toner or become worn out. They come in various sizes and configurations to fit different printer models.
