FEED Self Test
Different types of media may require different darkness settings. This section contains a
simple but effective method for determining the ideal darkness for printing bar codes that are
within specifications.
simple but effective method for determining the ideal darkness for printing bar codes that are
within specifications.
During the FEED self test, each label is printed at a different darkness setting, starting at three
settings lower than the print engine’s current darkness value and increasing until it is three
settings higher than the current value. The relative darkness and the print speed are printed on
each label. The bar codes on these labels can be ANSI-graded to check print quality.

The speed at which labels are printed during this print quality test depend on the dot density of

•
300 dpi print engines: 7 labels are printed at the 2 ips and 8 ips print speeds.
•
203 dpi print engines: 7 labels are printed at the 2 ips and 12 ips print speeds.
To perform a FEED self test, complete these steps:
1.
Print a configuration label to show the print engine’s current settings.
2.
Turn Off (O) the print engine.
3.
Press and hold FEED while turning the power On (I). Hold FEED until the DATA light

The print engine prints a series of labels (
) at various speeds and at darkness
settings higher and lower than the darkness value shown on the configuration label.
