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

Print a configuration label to show the printer’s current settings.

Turn off (O) the printer.

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 (

) at various speeds and at darkness settings 

higher and lower than the darkness value shown on the configuration label.
