Leibinger-Jet 2 se
Should ink dry in the nozzle as a result of operating errors or should the nozzle be
blocked with dirt particles or the ink jet not enter the gutter, the nozzle must be
dismantled and cleaned.
Experience shows that the cleaning of the nozzle with LEIBINGER solvent and blowing
out with compressed air against the direction of the current is sufficient to free the
nozzle. Should this not be possible, the nozzle must be cleaned in an ultrasound bath
(covered with LEIBINGER solvent) for at least 5 minutes and subsequently again blown
out with LEIBINGER solvent and compressed air.

In this respect it should be noted that the adjusted position of the ink jet cannot alter
suddenly. If the ink jet no longer enters the gutter this is usually due to the fact that dirt
particles or dried ink are situated in the nozzle intake.

In case of stubborn ink residue it can be permitted to remove the residue with a tooth-
pick (wooden only).
Caution: Risk of damage!
For this the nozzle is first of all rinsed out with LEIBINGER solvent and the jet is blown
dry from both directions with compressed air. Thereafter you move to the nozzle stone
(2) from both sides with a tooth-pick (wooden only). By means of light pressure and
turning the ink remains are detached from the nozzle stone. Subsequently the nozzle is
again rinsed with LEIBINGER solvent and blown out with compressed air.
Nozzle adjustment: once set correctly the nozzle retains its
position.
In the event of the jet varying from the normal position: Clean
nozzle until old position sets itself again automatically.
