If not, remove the DK Roll and reinstall.

• Has a print error or transmission error occurred?
Turn off the Brother QL printer and on again. If there is still a
problem, contact your Brother dealer.
• Is the power cord inserted correctly?
Check that the power cord is inserted. If inserted correctly, try
plugging it into another electrical outlet.
• Is the print head or roller dirty?
While the print head generally remains clean under normal use,
lint or dirt from the roller may become stuck on the printer head.
If this occurs, clean the roller.
See
"Roller maintenance" in page 17.
• Is the correct port chosen?
Check that the correct port is chosen from the "Print to the
following port" list in the Printer Properties dialog box.
• Is the QL printer in cooling mode (the LED lamp is flashing in
orange)?
Wait until the LED lamp stops flashing and then try printing
again.
• Is someone printing via network?
If you try to print while other users are printing large amounts of
data, the printer is unable to accept your print job until the
ongoing printing is finished. In such situations, execute the print
job again after the other jobs are completed.
• Check that the ejection path of the label is not blocked.
• Check that the DK Roll is set properly by removing the DK Roll
and reinstalling
• Ensure that the DK Roll cover is closed properly.
• Is there dirt or lint on the roller preventing it from rolling freely?
Clean the roller using the cleaning sheet (separately available).
For details, please see
• Close the P-touch Editor to exit the Add-In, and reactivate the
Add-In.
