Warning Messages
Displayed Message Description Possible Solution(s)
24V OUT OF TOLERANCE
The printer has detected a
drop in the 24-volt power
supply.
No action is required. If the problem
continues, cycle the power OFF and
ON.
DOT FAILURE
Defective printhead
elements have been
detected.
Replace the printhead if print quality
becomes unacceptable.
GAP MODE
WARNING LOW BACKING
Only a small difference
exists between the
measured ‘empty’ and
‘gap’ sensor readings.
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.
GOODBYE
Power has been removed
and printer shutdown is in
progress.
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.
HEAD NEEDS CLEANING
The scheduled printhead
cleaning distance has been
reached.
Clean the printhead (see Section
5.6.1).
To change the cleaning setting, enter
Media Settings / Printhead Cleaning
Menu.
HOST CHANGES PENDING
The host has changed the
configuration of the
printer, but those changes
cannot take effect until a
‘host reset command’ is
issued.
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).
