Broken Ribbon
Issue Possible Cause Recommended Solution
Broken or melted
ribbon
Darkness setting too high. 1. Perform the steps in Run the Print Wizard
and Print a Test Label on page 49.
2. If necessary, manually adjust the darkness or
print speed settings.
• Set the print darkness to the lowest setting
that provides good print quality. If you set
the darkness too high, the label image may
print unclearly, barcodes may not scan
correctly, the ribbon may burn through, or
the printhead may wear prematurely.
• Slower print speeds typically yield better
print quality.
Access the darkness and print speed
settings from the Home screen by touching
Menu > Print > Print Quality.
3. Clean the printhead thoroughly. See Clean
the Printhead and Platen Roller
on page 102.
The ribbon is coated on the
wrong side and cannot be used
in this printer.
Replace the ribbon with one coated on the
correct side. For more information, see Ribbon
on page 11.
