NOTE:
If the phasing error occurs only after high voltage has
been applied (i.e. it follows the
START PRINT command),
the reasons may be as follows:
the ink jet path is wrongly adjusted in relation to the
gutter - see section
4.4.4.8 Adjusting the Ink Jet
Path
,
the high voltage setting is too high,
a high voltage earth fault has occurred in the head;
this might have resulted from:
•
the failure to tighten up the screws or a damage to
the sealing of the HV electrode,
•
a damage to the insulation cover or cable of the
HV electrode,
•
the soiled head.

HV ON
**HV-ERROR**

EBS
It has two meanings:
the LED lamp emits a steady light - high voltage has
been applied to the head – a regular condition if the
printer is in the
print
mode,
the LED lamp flickers - high voltage has decayed or
cannot be maintained at the required level.
The error occurs when high voltage has not been applied
after the
START PRINT command, it has decayed during
the printing or the HV circuit cannot supply high voltage of
the required amplitude. The major reasons for the
HV ON
error are as follows:
•
an earth fault of the deflecting electrode due to a thick
layer of dry ink (NOTE : a risk of the ignition of ink
within the head ) - wash the head with solvent,
•
an earth fault of the HV cable,
•
a breakdown in the HV circuit,
•
a HV monitoring and control circuit failure,
•
a problem with the memory cell where the HV setting
is stored (when the printer has not been used for
a
long time and the back-up battery has
discharged) - select the SERVICE option from the
OTHERS submenu, type in the service password,
select the ADJUSTMENTS option and confirm the
selection with the
V
key. Then move to the
High voltage option and set the HV rated value.
The failure can be removed by a qualified person only.
Contact a service point.
