6.3.10. Irregular defects of print quality
PROBLEM REMEDY
The prints are made
properly but big spots of
ink appear here and there
within the print outline.
The reason for the occurrence of big drops of ink is the leaking
nozzle. Leaks may occur on the thread between the nozzle and the
gun or, less frequently, at the setting of the ruby in the nozzle holder.
The ink leakage flows towards the ink jet, then it is washed away by
the jet and thrown out as big ink drops.
Carefully screw the nozzle tight or replace it.
6.3.11. Slopping, rippled or jagged print
PROBLEM REMEDY
The print produced is
slopping, rippled or jagged.
The head holder has been fixed to an element that is subject to
strong vibrations or shocks. The head vibrates or shakes while
printing. Fix the head holder to a stable element that is not
subject to vibrations or shocks.
Objects to be labelled move on a conveyor and are subject to
strong vibrations or shocks. Make sure that the objects are in
stable position in front of the head so that they do not vibrate or
shake while labelled.
