A toner cartridge is the consumable component of a laser printer. Toner cartridges contain toner powder, a fine dry mixture of plastic particles, carbon, and black or other coloring agents that make the actual image on the paper. The toner is transferred to paper via an electrostatically charged drum unit and fused onto the paper by heated rollers during the printing process. Low-end to mid-range laser printers typically contain two consumable parts: the toner cartridge itself (which has a typical life of 2,000 Pages). Some toner cartridges incorporate the drum unit in the design and therefore replacing the toner means replacing the drum unit every single time, although some consider this type unessential and therefore not cost-effective.
