media you are using. If sensitivity is set
correctly, try changing the dark adjust.
Properly set the darkness adjust control.
Clean printhead, platen roller, and label path.

Use only Intermec label and ribbon stock to
ensure superior print quality and product
performance.

correctly.

given, testing for elimination of the problem
before performing the next alignment.
