Toner Cartridges - How They Work
In the past computers and their accompanying printers were huge. Toner reservoirs and toner cartridges were used instead of ink cartridges like the ones in use today. Toner cartridges were difficult and messy to fill. The toner cartridges were an advancement. Some printers ran on print wheels and some used ribbons. Computers are compact and printers now do more than just print on some cases. Cartridges with self-contained reservoirs are used in printers. Refilling some cartridges is possible and it isn't as messy as adding toner was. Two types of printers cartridges now exist. Hewlett-Packard and Epson printers primarily, used the first type the Peizo Electric. An electric current is applied to a small crystal causing it to expand about every five microseconds (20,000 per second). The ink, because of the expansion, squirts through the print heads rapidly and precisely. Piezo Electric can do more precise action and tend to last longer because it has fewer print heads than do bubble jet/ thermal printers. Bubble jet printer cartridges heat the ink into a bubble and is squirted through the ink nozzles thousands of times a second. The printer that is quieter than Piezo based printers is the bubble jet. It prints with exceptionally high resolution color printing. Ink is squirted through the nozzles as they move over media in the inkjet method not the mega pixel method. Liquid ink, is squirted, in various colors on the paper to create an image. A motor assembly is used to enable the print heads to scan the page horizontally while the page is rolled vertically. A narrow band of an image is printed and the paper moves on ready for the next step. For speed it prints a strip across the page while it also prints vertical rows of pixels in each pass. There are several types of inkjet technology. DOD-drop on demand squirts small drops of ink on to the paper through tiny nozzles. It is akin to a hose being turned on and off 5,000 times per second. The amount of ink dropped on the paper and which nozzle fires and when is controlled by the driver software. The ink tends to smear right after printing in inkjet technology. This is getting better as new ink compositions are developed. The Thermal Technology of printing allows the ink to shot onto the paper. This is a three stage process. The squirt begins in stage one when the ink gets heated to create a bubble. The initial pressure breaks the bubble and hits the paper. The vacuum that results pulls the ink from the reservoir to replace what was ejected. In the past printers were highly priced because the print head that would imprint the image on paper was contained within the printer. Printers are fairly low in price, but the expense comes when you have to buy cartridges for it. It would almost be worth it to buy a new printer rather than the cartridges because the cost of cartridges is often more than the most basic inkjet printer. Although cartridges are expensive they have some complex technology in them that would make them cheaper over-all than it would be to keep replacing printer heads. Cartridges now have print heads contained within in themselves. If you use the correct cartridges in your printer, you could have the printer for a long time. Black cartridges work by squirting the ink through tiny nozzles onto the paper as they move back and for the page as do color cartridges. Color cartridges have three reservoirs; one is filled with magenta, one with cyan, and one with yellow ink. A lot of things can have a bearing on the image quality. The quality of the paper you choose could determine the image you get. The two main influences on image quality are brightness and the absorption of ink. The vividness of an image describes its brightness while how effectively ink is put to the paper is absorption. It is best to use paper specifically designed to be used with an ink jet printer. Using the proper type of paper will result in the best possible image. The settings of your display properties and/or printer settings can affect your printing project. The type of paper you use and the printer may suggest leaving your documents to dry for awhile. Check your printer for settings that may save ink by putting out less ink allowing documents to dry faster and provide you with a near perfect print image. Knowing your printer and how it works is important. About the Author
