• The printhead may have had a ‘THERMAL SHUTDOWN’ error. Turn off the printer 
power and let the printer sit for several minutes before reapplying power. If it still get the 
error, return the printer to an authorized reseller.
10. The printer is defragmenting memory.
Caution • Do NOT turn off the printer power during defragmentation. Doing so can damage 
the printer.
• Defragmentation is a normal operation of the printer – necessary to manage the memory 
space for optimal use. The printer will defragment its memory both after a factory default 
and when the printer detects that a defragment is required.
When the printer is in this condition, allow it to finish defragmenting. If this warning occurs 
frequently, check the label formats. Formats that frequently and repeatedly write to and 
erase from memory my cause the printer to defragment often. Using formats that avoid 
frequent and repeated memory write/erase event will minimize the need for 
defragmentation. 
• If this warning condition does not go away, contact Technical Support. The printer 
requires service.
