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
technology. A controlled
electric charge to the
piezoelectric ceramic produces
a pumping action, forming
and ejecting ink-droplets.
3.
The print head assembly
on the carriage, with
connecting ink cartridges,
moves back and forth across
the paper to produce the
desired image.
4.
A stepper motor drives
gears and rollers designed
to advance the paper with
precision each time the print
head assembly is ready for
another pass across the
paper. The paper is then
ejected once the printed
image is complete.
