Troubleshooting
Printing or Print Quality Issues
Barcode Does Not Scan
Issue Possible Cause Recommended Solution
The barcode printed on a
label does not scan.
The barcode is not within
specifications because the printer
is set at an incorrect darkness
level.
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
Quality
.
1. If the issue is not resolved, check the printhead
pressure and toggle position. See Adjust the
Printhead Pressure on page 90
There is not enough blank space
around the barcode.
Leave at least 1/8 in. (3.2 mm) between the barcode
and other printed areas on the label and between the
barcode and the edge of the label.
Wrong Image Size
Issue Possible Cause Recommended Solution
My label prints too small
(or too large)
The wrong printer driver is being
used, or other settings are not
correct for your printing application.

settings (if applicable) for your connection. You may
wish to reinstall the printer driver following the
instructions in Install the Printer Driver and Connect to
a Computer on page 137.
