Early inkjet printers and large format inkjet printers are currently using continuous ink-jet technology, inkjet printers are generally popular in the current market with random ink-jet technology. Both types of ink-jet technology in principle there is a big difference.
inkjet printer on if, in the print format, can be roughly divided into A4 inkjet printers, inkjet printer A3, A2, inkjet printers if you use, it can be divided into ordinary inkjet printers and digital photo printer, portable mobile inkjet printer.
inkjet printer works
continuous inkjet technology, continuous inkjet technology represented by the charge modulation type. This inkjet principle is to use piezoelectric devices to ink in the nozzles fixed pressure, its continuous spray. For recording, use oscillators generate vibration signal Jet ink droplet, and to control the ink droplet size and spacing. The character generator, analog modulator of printed information to control the control telegram charges, formation of charged and uncharged ink droplet, and deflection electrodes to change the direction of drops of ink, ink droplet flight to paper you want to print, and character/graphic records. No ink droplets composed of vessels involved in the record collection. Of deflection electrodes, some system uses two mutually perpendicular deflection electrodes, ink drops printed two-dimensional transformation using multidimensional control system for deflection electrode, multidimensional deflection.
this cycle of continuous ink jet systems. high-speed ink droplet can be generated, so the high print speeds, you can use plain paper. Different print media can get a high quality print results, and easy color printing. However, this compared to inkjet printers-structures with random, more complicated: the ink needs to pressure device, Terminal of recovery recovery does not participate in such records. And the working efficiency is not high enough, and are not accurate. Now using this technique of ink-jet printers have been rarely seen.
2, random ink-jet technology
random ink-jet Ink Jet only printing needs in the system, it is also known as on-demand. It compared with continuous, simple structure, low cost, high reliability, but due to inertial effects of droplet ejection by jets at low speeds. This random ink-jet systems, in order to make up for the shortcomings, many random ink-jet printer using a nozzle to increase the printing speed.
