FC35 Gutter Problems
The faults which can occur in the gutter line are as follows:
● blocked gutter which can be due to:
incorrect shutdown not purging the gutter;
print head mounted lower than the printer (causing siphoning effect);
● ink leaking from the gutter during a period of non-use:
print head mounted lower than the printer (causing siphoning effect).
● poor gutter action (inadequate suction):
Very thick ink, e.g. pressure is 40 points above the reference pressure value.
If you suspect a gutter blockage, do not attempt to clear it yourself; contact EC-JET or your local
distributor.
FC36 Vibration Problems
Poor print quality is the most common indicator of vibration problems. This is because the print drops are
relatively stable while in flight, so vibration in either the product being marked or the print head it will
result in the drops being misplaced or obstructed.
Diagnosis
To determine whether high frequency vibration is affecting the product or the print head, simply pass a
piece of paper under the print head and trigger the print. Take care to move the paper at a steady speed.
If it is the product which is vibrating, then the print quality will be good. If the print quality is poor, the
vibration is likely to be coming from the print head.
