Thermal Inkjet Technology
Ink-jet technology centers on a disposable print cartridge, which propels ink out of 300
nozzles (192 nozzles on the color print cartridge). The basic principle is to apply heat to
a tiny measure of ink until it expands and is propelled through a nozzle. This is
achieved by first filling a small reservoir, known as the firing chamber with ink. The next
step is to heat the ink with a thin-film resistor layered above the firing chamber. As the
ink heats up, it expands to form a bubble. As the bubble continues to expand and burst,
it is forced through the nozzle located below the firing chamber. This process is
repeated up to 12,000 times per second.
