Problem Solution
Received data in buffer Print data is saved in the buffer. If the Label Printer has not received
the complete data, printing will not start.
Turn off the Label Printer, and then turn it on again.
Head is cooling down The thermal head is too hot.
The Label 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
outside the print area. To avoid or delay overheating, make sure the
Label Printer has adequate ventilation and is not located in an
enclosed space.
If the Label Printer must cool down because it overheated due to
the type of DK Roll you are using or the contents of the label,
printing may take longer than usual.
Note
This condition may occur more often when the Label Printer is
used at high altitude (more than 10,000 ft (3,048 m)) due to a
lower air density available to cool the Label Printer.
Label Printer is in boot mode To resolve the issue, contact your Brother dealer or Brother
Customer Service for assistance.
