Can You Explain The Working Of Ink Jet Printer With The Application Of Electronics?

Ink jet printer is an important invention being used successfully in these days. It is considered as a preference because of the less investment being made initially and is easy to maintain as well. Ink jet printer is a printer, which uses electric charge in its operation. The inkjet printer ejects a very thin stream of ink which is forced to come out of a nozzle, in the form of very small droplets during the spray of ink the inkjet moves to and fro on the paper.

The small droplets come from nozzle of inkjet printer and pass through charging and deflecting regions. Two plates are connected with battery. These are called deflecting plates. When print head passes over the regions of paper, which are not to be inked (printed), the charging electrode become ON and these give electric charge to the ink droplets. When these charged ink droplets pass through deflecting plates, then  these experience electric force due to charge on them, and these are deflected towards gutter. In this way these droplets can not reach the surface of sheet of paper.

When ever ink is to be placed on the sheet of paper to give print on it, then charging electrodes become OFF. The ink droplet remain un-charged so these experience no electric force while passing through the region between deflecting plates towards gutter and fall straight on the sheet of paper.
