1 - A cartridge (cartridge) with ink on the print head (print head) printer inkjet moves the lateral extension of the paper, which in turn is powered by the tractor printer under the printhead.
2 - The print head comprises ink compartments 50, each connected to an orifice (nozzle) smaller than a thread hair.
3 - An electrical pulse flowing through thin transistors, located at the bottom of all compartments (chambers)
the printer will use to build the character on paper.
4 - When electric current flows through a resistance (resistor), it heats a thin layer of paint on the
lower compartment to more than 490 degrees Centigrade for a few millionths of a second. The paint (ink) boils forming a bubble (bubble) of steam.
5 - When the vapor bubble expands, it pushes ink through the orifice to form a droplet (droplet) on the tip of the ink orifice.
6th - the drop breaks the surface tension of the ink and pressure of the vapor bubble forces ink onto the paper. The volume of
ink dumped is about a millionth drop of water coming out of a dropper. A typical character is formed by
a sequence of 20 drops high by 20 wide.
7 - When the resistance cools, the bubble bursts. The resulting suction draws a new portion of the ink reservoir attached
compartment for heating (firing chamber).
