Canon i80 Color Bubble Jet Printer
In conventional print heads, the temperature and viscosity of the ink when it leaves the nozzle can produce slight fluctuations in the amount and direction of ink discharged. To overcome this fundamental problem, Canon attached a heater, which heats and vaporizes the ink inside the nozzle to form microbubbles, in an ideal position closer to the nozzle outlet. Under the pressure of these bubbles, ink is ejected out of the outlet in microfine droplets.
