Issue Possible Cause Recommended Solution
General print quality
issues
The printer is set at an incorrect
print speed or darkness level. Keep
in mind that printer settings may be
affected by the driver or software
being used.
For optimal print quality, set the print speed and the
darkness to the lowest possible settings for your
application.
1. Perform the steps in Run the Print Wizard and Print
a Test Label on page 52.
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
