1.
The Brother print head
has four ink-jet elements
servicing four colour inks.
Each inkjet element consists
of nozzles and channels
covered with a piezoelectric
ceramic actuator and filter.
2.
Ink is sprayed through
microscopic nozzles in the
print head onto the paper
using piezoelectric ceramic

piezoelectric ceramic produces
a pumping action, forming
