1
Chipped print
(minus deflection
electrode side)
Ink and foreign matter are
stuck to the gutter.
●
Clean the gutter.
●
Replace the recovery
filter.
6.6 (*1)
6.8 (*1)
Ink and foreign matter are
stuck to the charge and
deflection electrodes.
●
Clean the charge and
deflection electrodes.
3.1.2
Ink and foreign matter are
stuck to the ink ejection port.
●
Remove the ink and foreign
matter.
-
The ink stream is improperly
positioned.
●
Adjust the ink stream.
6.5 (*1)
The ink pressure is too high.
●
Adjust the ink pressure for
the standard value.
6.10 (*1)
The ink has deteriorated.
●
Replace the ink.
6.3 (*1)
2
Chipped print
(plus deflection
electrode side)
Ink and foreign matter are
stuck to the charge and
deflection electrodes.
●
Clean the charge and
deflection electrodes.
3.1.2
Ink and foreign matter are
stuck to the ink ejection port.
●
Remove the ink and foreign
matter.
-
The flow within the nozzle is
restricted.
●
Backwash the nozzle.
6.4 (*1)
The character height setting is
too great.
●
Decrease the character
height setting.
4.14.1
The ink pressure is too low.
●
Adjust the ink pressure for
the standard value.
6.10 (*1)
The ink has deteriorated.
●
Replace the ink.
6.3 (*1)
3
Varying character
height
The clearance between the
print head and print target has
changed.
●
Adjust the clearance
between the print head and
print target.
-

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.
