Description
The printer has detected a
drop in the 24-volt power
supply.
Defective printhead
elements have been
detected.
Only a small difference
exists between the
measured 'empty' and
'gap' sensor readings.
Power has been removed
and printer shutdown is in
progress.
The scheduled printhead
cleaning distance has been
reached.
The host has changed the
configuration of the
printer, but those changes
cannot take effect until a
'host reset command' is
issued.
Possible Solution(s)
No action is required. If the
problem continues, cycle the
power OFF and ON.
Replace the printhead if print
quality becomes unacceptable.
No action is required. During
calibration, labels mounted on a
transparent liner or notched
media may give this indication.
A slight delay in the 'Out of
Stock' message may occur.
AC line voltage has been lost.
The power switch was turned
OFF or the line fuse has blown.
If unable to restore power using
the power switch, try moving
the printer to another location
and if the condition persists,
call for service.
Clean the printhead (see
Section 5.6.1).
To change the cleaning setting,
enter Media Settings /
Printhead Cleaning Menu.
To save these changes, send a
host reset command (in DPL);
or, to discard the changes,
perform a soft reset (see
Section 5.7.1).
