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.
During the FEED self test, labels are printed at different darkness settings at two different print
speeds. The relative darkness and the print speed are printed on each label. The bar codes on
these labels may be ANSI-graded to check print quality.
The darkness value starts at three settings lower than the printer’s current darkness value
(relative darkness of –3) and increase until the darkness is three settings higher than the current
darkness value (relative darkness of +3).
The speed at which labels are printed during this print quality test depend on the dot density of
the printhead.
• 300 dpi printers: 7 labels are printed at the 2 ips and 8 ips print speeds.
• 203 dpi printers: 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 printer’s current settings.
2. Turn off ( O ) the printer.
3. Press and hold FEED while turning on ( I ) the printer. Hold FEED until the first control
panel light turns off.
The printer prints a series of labels ( Figure 36 ) at various speeds and at darkness settings
higher and lower than the darkness value shown on the configuration label.
