(1) The nozzle is charged with ink.
(2) The ink on the heater surface is suddenly heated to form small bubbles
when the heater is turned ON in an extremely short period.
(3) The ink suddenly vaporizes for form bubbles.
(4) The bubbles expand to maximum size, and an ink drop is pressed out-
side the nozzle.
(5) The heater temperature drops and the bubble suddenly shrinks. This
causes the ink that was pressed outside to form into liquid.
(6) When the heater temperature drops further, the ink drop flies out of the
nozzle. The ink that flies out of the nozzle is charged in the nozzle
from the ink tank by
capillary
phenomenon.
