No.
Printing failure
description
(phenomenon)
Probable cause Solution Reference
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 (*2)
6.8 (*2)
Ink and foreign matter are
stuck to the charge and
deflection electrodes.
● Clean the charge and
deflection electrodes.
7.1.2
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 (*2)
The ink pressure is too high.
● Adjust the ink pressure for
the standard value.
6.9 (*2)
The ink has deteriorated. ● Replace the ink. 6.3 (*2)
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.
7.1.2
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 (*2)
The character height setting is
too great.
● Decrease the character
height setting.
4.14.1
(*1)
The ink pressure is too low.
● Adjust the ink pressure for
the standard value.
6.9 (*2)
The ink has deteriorated. ● Replace the ink. 6.3 (*2)
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.
-
Ink and foreign matter
are stuck to the charge and
deflection electrodes.
● Clean the charge and
deflection electrodes.
7.1.2
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 (*2)
The ink pressure has changed.
● Adjust the ink pressure for
the standard value.
6.9 (*2)
The ink has deteriorated. ● Replace the ink. 6.3 (*2)

9.3 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.
