A
toner cartridge, also called
laser toner, 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 electrostaticallycharged drum unit, and fused onto the paper by heated rollers during the printing process.
3. 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) and the drum unit (a typical life of 40,000 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.
Toner Cartridges are similar to
ink cartridges, which are used in Inkjet printing.
