Problem
Received data in buffer
Head is cooling down
Label Printer is in boot mode
DK Roll errors
I want to reset an error
Solution
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.
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.
To resolve the issue, contact your Brother dealer or Brother
Customer Service for assistance.
Check the following:
• You are using the correct DK Roll.
• There are enough labels remaining.
• The DK Roll is installed correctly.
To reset an error:
1 Open the DK Roll Compartment Cover, and then close it.
2 If the error is not reset, press the Cutter (
3 If the error is not reset, turn off the Label Printer, and then turn
it on again.
4 If the error is not reset, contact Brother Customer Service.
