[Causes and Solutions]

Tube, Label, Power indicator

Condition

Cause

Solution

Now cooling

The thermal head is too hot.
The printer stops and resumes printing only after the thermal head has cooled down.
The head may become too hot if you are printing a large number of labels.
When the thermal head becomes too hot, it may produce imaging on the labels in areas not intended to be printed.

 

This condition may occur more often when the printer is used at high altitude (more than 10,000 ft (3,048 m)) due to a lower air density available to cool the printer.

 

High temperature error.

 

To avoid or delay overheating, make sure the printer has adequate ventilation and is not located in an enclosed space.
Do not use the printer continuously or the print head will become too hot. In this case, the printer will stop and resume printing after the motor has cooled down.

Wait for approximately 5 minutes.

Cutter error (Tube)

The tape cutter is closed when you try to print or feed tube.

This error also appears if the cutter does not operate correctly while cutting.

Tube jam error (Tube)
Tube feeding problem (Tube)
  1. You have reached the end of the ribbon.
  2. The tube is jammed.
  3. If the printer cannot feed the tube correctly because the tube is twisted or the tube is caught on something outside of the printer, this error may occur.
  1. Check that there is enough ribbon remaining.
  2. Check that the tube is not jammed.

    When the tube is jammed, the ribbon of the ribbon cassette will be damaged.  Because the ribbon may break if you use it in this condition, pull out approximately 3–5 cm of ribbon from the cassette and wind the damaged portion completely onto the spool.  You can use the ribbon to print starting from the portion that is not damaged.
  3. Check that the tube is not twisted and that the tube can be fed smoothly outside of the printer.  If it is twisted or caught on something, remove the tube from the printer and insert it again.
