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

GAP MODE 
WARNING LOW 
BACKING 
 
Only a small difference 
exists between the 
measured ‘empty’ and ‘gap’ 
media 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 
(after the media supply is emptied) may be 
experienced.  
 
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.
