PRINTER DESCRIPTION
PRINT HEAD
General Principles
Each printed character consists of a dot
matrix made up of lines, or strokes, of ink
drops. The ink drops in each stroke are
spaced apart by electronic deflection and the
strokes are spaced apart by the movement of
the print surface under the head.
Inside the print head, ink is supplied under
pressure to the drop generator, and emerges
through a small nozzle as a very fine jet. The
drop generator contains a drive rod which
creates ultrasonic pressure waves in the ink,
making the jet break up into a stream of
separate drops shortly after leaving the
nozzle.
The break--up is adjusted to occur within the
charge electrode, where each ink drop is
given an electrostatic charge by putting a
voltage onto the charge electrode as the drop
breaks off. The size of the charge on the ink
drop depends upon the voltage on the charge
electrode.
The ink drops then pass through the
electrostatic field set up between between
two high voltage deflector plates.
The
direction of flight of each charged ink drop is
deflected by an amount dependent upon the size of the charge.
Ink drops not required for printing are not given electrostatic charges
and are collected in the gutter.
Details
The print head components are mounted on a rigid chassis, with a fully
enclosed top section containing the connections between the print head
and conduit wiring.
