9.4 Remedial Action to Be Taken in the Event of a Printing
Failure
● If a printing failure occurs, perform the associated remedial procedures suggested below.
● If the remedial procedures below do not achieve recovery, it is conceivable that the problem is
attributable to a PC board or circulation system failure. In such an instance, contact your nearest local
distributor.

The character height setting is
too great.
The ink pressure is too low.
The ink has deteriorated.
The clearance between the
print head and print target has
changed.

are stuck to the charge and
deflection electrodes.
Ink and foreign matter are
stuck to the ink ejection port.

The ink has deteriorated.
Solution
● Clean the gutter.
● Replace the recovery
filter.
● Clean the charge and
deflection electrodes.
● Remove the ink and foreign
matter.
● Adjust the ink stream.
● Adjust the ink pressure for
the standard value.
● Replace the ink.
● Clean the charge and
deflection electrodes.
● Remove the ink and foreign
matter.
● Backwash the nozzle.
● Decrease the character
height setting.
● Adjust the ink pressure for
the standard value.
● Replace the ink.
● Adjust the clearance
between the print head and
print target.
● Clean the charge and
deflection electrodes.
● Remove the ink and
foreign matter.
● Backwash the nozzle.
● Adjust the ink pressure for
the standard value.
● Replace the ink.
