HELP Key
The HELP key is used to diagnose printer faults that have
occurred in the printer. The printer does not provide diagnosis
information for warning conditions.
Pressing the HELP key while the SERVICE light is flashing will
display printer fault information in the display screen.
HEAD Key
The HEAD key is used to turn the printhead On or Off. The
printhead can be turned On only when both the ink and high
voltage are On. The HEAD key must be On for the printer to be
able to print a message.
NOTE:If the ink is turned off longer than five minutes, the air
control solenoid is automatically de-energized and the
HEAD key must
be pressed to reactivate the printer.
HEAD Key Summary
=
Light is ON:
This indicates that the printer has completed the
start–up sequence, and the printhead is now active (ink is On,
High Voltage is On). To print a message, press the
PRINT
key
(refer to the Print Key on page 3-15 for further information). To
make the printhead inactive, press the
HEAD
key.
CAUTION: High Voltage is applied to the printhead when
the HEAD key is On.
Light is FLASHING:
This indicates that the printer is currently
performing the printhead start-up sequence (ink is On, High
Voltage is Off). Once the printhead start-up sequence is
completed, the light will stay On. To stop the start-up sequence
while in progress, press the
HEAD
key.
Light is OFF:
This indicates that the printhead is not active (ink
is Off, High Voltage is Off), therefore it cannot print a message.
To make the printhead active (start the printhead start-up
sequence), press the
HEAD
key and wait until the light on the
key is lit (solid, not flashing).
