FEED Self Test
This test helps you choose the best darkness setting for your printer.
To perform a FEED self test, complete these steps:
1. Turn Off (O) the printer.
2. Press and hold FEED while turning the power On (I). Hold FEED until the DATA light
turns off.
The printer prints a series of labels (
Figure 52 ) at various speeds and at darkness settings
higher and lower than the darkness value shown on the configuration label.
Figure 52 • FEED Test Label
3. Inspect the labels and determine which one has the best print quality for your application.
The darkness value printed on that label is added to (plus) or subtracted from (minus) the
darkness value specified on the configuration label. The resulting numeric value (0 to 30)
is the best darkness value for that specific label/ribbon combination and print speed.
4. Enter the corresponding darkness and print speed values into the printer through the front
panel.
