TROUBLESHOOTING
This chapter explains how to adjust print quality and contains basic troubleshooting
information. If you need to call Technical Support, print a test label first. See “
Printing a
Test Label” in Chapter 1 for more information.
Adjusting the Print Quality
Many factors impact print quality: type of supplies, print speed, print contrast, and the
printer application. The printer supports both thermal transfer and thermal direct supplies.
The type of supply should match the printer’s application.
♦ Use premium supplies if you want to print at high speeds.
♦ Select the print speed based on desired throughput and print quality. If print quality is
more important, reduce the print speed. A lower print speed increases the print
quality of labels. If throughput is more important, increase the print speed.
♦ If the print quality is too light or too dark, adjust the print contrast.
♦ A bar code that is in spec has complete bars, clear spaces, and small alphanumeric
characters look complete. An in spec bar code may not look as good as one that is
too dark, but it has the highest scan rate.
Setting the Print Contrast in Online Mode
Having the correct print contrast/density setting is important because it affects bar code
scan ability and printhead life.
To change the print contrast:
1. From the Main Menu, select Menu.
2. Press the navigation button until Online Setup is highlighted. Press Select.
3. Press Select when Contrast is highlighted. Use the navigation buttons to select
which position to change, then increase or decrease the value. Press Select when
finished. The print contrast range is -156 to 156 and the default is 0.
4. Press Back until you see the Main Menu.
