With your Inkjet Printer: How Do you use it?

Have you ever wondered how your inkjet printer works?How does the ink get from the inkjet cartridge to the traditional? Why is the print quality is so certain? Why the printing is so quiet? Generally, all that most people know would be the there's some movement and a faint high pitched sound when it's printing something -- and then the finished document comes out.Unlike dot matrix and character printers that strike ribbons to create an image, inkjet printers do not physically touch the report. All inkjet printers function using the same basics. Tiny ink droplets are 'jetted' (or pushed) out multiple holes onto paper in a controlled and systematic fashion. This is where the term 'inkjet' comes from.The size of ink droplets, speed and longevity of this type of printer has been continuously improving since its inception. In 1993, Epson was your first manufacturer to produce an inkjet printer using micro-piezo technology. The Epson Stylus 800 was the first printer to use the multi-layer actuator printhead (the printhead is the part of the printer that holds numerous tiny nozzles that actually squirts the ink onto paper). This specific printhead utilized an electro-mechanical element that acted like the smallest control room. When pulses of electricity passed through, it that gave specific signals to fire individual or multiple nozzles loaded with ink. Micro-piezo technology utilized a tiny crystal each individual nozzle that when electrically energized, would vibrate or bend causing a controlled amount of ink to be forced out onto paper. When the electrical current is off, the crystal bends to be able to its original shape, creating a vacuum, thus pulling ink into the nozzle from the reservoir for the next commanded fire. The Epson printhead was fixed to your carriage so it never needed replacing (the printer carriage is what moves laterally across the paper). This also kept the cost of ink cartridges low from when they were little more than reservoirs of ink. This breakthrough printer produced a whopping 360 dpi (dots per inch) that was deemed, almost 'letter quality' during those times. With a printing speed of 150 - 180 characters per second, the new Epson became the user favorite printer for home and office.At the same time, HP was using exactly the same technology. A thermal jetting system was utilized of their printhead. The printhead still acted like the control room but each individual nozzle was instead independently super heated by electricity, which caused the ink to explode onto the paper. HP claims the temperature of a fired inkjet nozzle approaches that the surface of sunlight. HP elected to put the printhead on the inkjet cartridge itself instead of mounting it permanently on the carriage. Since each inkjet cartridge would have specific printhead, replacement cartridges that i see more expensive for these printers. HP inkjet cartridges also could not print as fast as Epson because each nozzle to be able to cool after firing. This heating technology also limited the types of inks that could be utilized ..In the 1990's, Canon, Epson and HP engineered printheads that applied even smaller droplets of ink, drastically improving dpi and solution.While Canon and HP could produce a 6 - 10 picoliter droplet size from one nozzle, Epson was about half over all size (between 3 - 6 picoliters). Currently, there are printers available which will produce an amazing 1 picoliter droplet! To achieve an idea of how small this is; a natural splendor is about 12 picoliters in diameter. Most human eyes can't see one jetted droplet of ink on paper. Inkjet printers have come a good distance since their first release.Printers today are twice as fast as their predecessors were, and are less than ever. Many printers might produce color photo quality images in at a fabulous 6000 dpi. As time goes on and as demand for printing remains high, the quality, speed and features of inkjet printers will only in order to improve.About The Author:Bob Stephens is director of operations for ASAP Inkjets.
