JET2 neo Release R1.12 en
The print head contains all mechanical, electronic and hydraulic components which are
required for the creation of print out. It is connected with the hydraulic cabinet by a flexible
umbilical.
The JET2neo works in accordance with the continuous ink jet process. In this a constant
ink jet is emitted from a jet nozzle which is broken down into a series of equal size drops
under the influence of mechanical oscillations.
If required these drops are individually charged up electrostatically and deflected into a
constant electrical field depending on the charge. As a result not just one point but rather
a line of points can be applied contact-free with one jet. If the product used is moved
vertically to the drop deflection two-dimensional patterns (characters) can be created.
The drops that are not required for a programmed inscription are not charged and flow
uninfluenced through the electrical deflection field into a gutter. In the gutter the drops are
sucked up by a suction pump and fed back into the ink tank. Depending on the application
alphanumeric data and graphics can be entered with the TFT touch display.
Data for font and texts are stored in the device (even in the event of
power failure). If required it can be called up, altered or deleted quickly
and easily.
Further more, all jobs, fonts and graphics can be saved as a back-up
e.g. on a USB-stick.
During the drop creation the ink is pressed through a jet nozzle under pressure and at the
same time modulated in such a way by highly frequent sinus oscillations that are imposed
on the drop that it attaches itself to the nodal points of the oscillations and breaks down
into individual drops at a specific distance l

(please see the following figure “Creation of
a character”) from the jet. The oscillations are created with an oscillatory system that is
excited by a Piezo oscillator.
