Print Head
The image below shows the printhead with the covers removed. High pressure ink is forced through a
nozzle located on the end of the Drop Generator as a continuous stream. The Resonator Probe in the
Drop Generator vibrates and causes the ink stream (or Jet) to break up into a steady stream of droplets.
Droplet breakup occurs in the middle of the charge electrode while a precise negative voltage is applied
to the drops to be printed. Next droplets pass through the deflection field where the charged drops are
pulled from the stream to exit the printhead to land in a precise pattern on the substrate to form
characters.
The deflector plates create a constant electric field which deflects the charged ink droplets.
Uncharged droplets are collected in the gutter to be returned back to the Ink System to be reused.
