The way of the modern world requires that businesses invest in copy and print technology such as scanners and fax machines, as well as computers to run orders to these machines. Companies must not only be able to easily accept the information which their customers send, they must also be able to keep quick and clean records of what happens in their business. There are various kinds of printers from inkjets to laser printers. Laser printers output materials very quickly and so are often preferred over basic ink printers in spaces where much material needs to be printed.
The science of a laser printer lies in photoconductivity and the electrostatic attraction that makes the dry ink inside of a toner cartridge stick to paper. A laser projects a portion of the page that has been sent for printing onto an electrically charged piece, called a drum, that is coated with the chemical semiconductor selium, or in more modern products, with organic photoconductors. The laser’s light takes away atomic charge from the areas that have been exposed to light through the photoconductivity phenomenon. Dry ink called ‘toner’ is then left to attach only to the areas of the previously exposed ‘drum’ which are still electrically charged.
The ink in toners is not liquid or even dried out common ink but a powdered combination of materials. Toners used only powdered carbon when they were first invented. The quality of laser printed material was increased when producers began to mixing polymers, or plastic compounds, in with the original carbon powder. Polymer, that is, plastics, waxes, resins of various sorts, and carbon might all be found in different selections of today’s printer toner cartridges.
Smaller particles make for a more pleasing print as well as slightly lighter wallet. Certain toner companies are even working on ‘growing’ new and smaller materials to use in their cartridges.
All of the materials within a toner cartridge have a natural charge that is attracted to the opposing charge of the non-lasered areas of the mechanical moving drum inside of the printer. To make the powdery ink combinations stick to paper, heat is applied, and the material melts into letters, shapes, and words.
When laser printers were first used in the 1980’s people had to refill their toner cartridges manually through a messy and time consuming process. Modern toners are replaced whole, with their containers. This is a very expensive drain on the environment, which cannot biodegrade most of the plastics used in both the printer’s ink and the holding container. Certain companies actually have the drum replaced along with each refill of the ink container. Sustainability is however speaking its message, and companies are listening to consumer’s demands that their product be a safe choice for the earth and the human population’s future. Modern producers now work to make toner and cartridges more sustainable and less draining on the environment’s future health.
