Injket Printers Mechanism. An inkjet printer is a printer that uses electric charge in its operation.

While shuttling back and forth across the paper, the inkjet printer ejects a thin stream of ink.

That ink is forced out of a small nozzle and breaks up into extremely small droplets.

During their flight, the droplets pass through two electrical components, a charging electrode and deflection plates.

When the printhead moves over the regions of the paper which are not to be inked, the charging electrodes give the droplets a net charge.

The deflection plates divert such charged drops into the gutter and in this way, such droplets are unable to reach the paper.

Injket Printers Mechanism. Whenever ink is to be placed on the paper, the charging control, responding to the computer, turns off the charging electrodes.

The uncharged droplets fly straight through the deflection plates and strike the paper.

These printers can also produce color copies.
