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).

Depending on the dot density of the printhead, seven labels are printed at each of the following speeds:

•203 dpi printers: 2 ips, 6 ips, and 10 ips

•300 dpi printers: 2 ips, 6 ips, 8 ips

•600 dpi printers: 2 ips, 4 ips

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 21) at various speeds and at darkness settings higher and lower than the darkness value shown on the configuration label.
