Toner Cartridges in Laser Printers

Get to know more about toner cartridges for laser printers

Laser toner cartridges function with high voltage and a very fine toner powder. The toner powder is placed into the paper with the help of magnetic developer roller, drum and laser beam. Drum is a very photo sensitive material. Character is formed by electrically charged particle and it's placed on paper which is also electrically charged. So characters could be placed easily into the paper. Characters are placed into paper permanently by passing the paper through fuser roller which has high temperature. Thus characters could melt and fix permanently into the paper. The drums are very delicate and sometimes get damaged because of exposure to sunlight. Some laser printers have drum shutters which protect them from direct sunlight. Toner cartridges could be refilled and hence this could be used for longer duration. Primary items used in laser toner cartridges are drum, toner, corona wires and cleaning blades gears and moving objects.
