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.
