The toner is printed directly onto the drum, by direct contact with a rubber developing roller which, by reversing the bias, removes all the unwanted toner and returns it to the developer unit for reuse. The development of xerography has led to new technologies that have the potential to eventually eradicate traditional offset printing machines.
Toner can be washed off skin and garments with cold water. Hot or warm water softens the toner, causing it to bond in place. Toner fused to skin eventually wears off, or can be partially removed using an abrasive hand cleaner. Toner fused to clothing usually cannot be removed. Unfused toner is easily cleaned from most water-washable clothing.
Toner may refer to: Toner (printing), a powder mixture used in laser printers and photocopiers; Toner (skin care), a water-based lotion, tonic, or wash designed to cleanse the skin in preparation for other skincare products; Hair toner, product used in hair dying; Toner cartridge, component of a laser printer which contains toner powder
The toner is then fused onto the paper using heat, pressure, or a combination of both. Copiers can also use other technologies, such as inkjet , but xerography is standard for office copying. Commercial xerographic office photocopying [ 1 ] gradually replaced copies made by verifax , photostat , carbon paper , mimeograph machines , and other ...
Xerox was founded in 1906 in Rochester, New York, as the Haloid Photographic Company. [12] It manufactured photographic paper and equipment. In 1938, Chester Carlson, a physicist working independently, invented a process for printing images using an electrically charged photoconductor-coated metal plate [13] and dry powder "toner".
electrophotography – where toner is attracted to a charged image and then developed; laser – a type of xerography where the charged image is written pixel by pixel using a laser; solid ink printer – where solid sticks of ink are melted to make liquid ink or toner
Black toner particles adhere to areas on the paper that remain charged; discharged areas do not attract toner particles. A knife then cuts the paper to the proper length (typically letter or legal size). The subsequently independent sheet of paper then passes from the toner station, where excess dispersant is wiped off.
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.
