FEED Key Self-test
Press and hold the FEED key while turning the printer power ON. Re-
lease the key anytime after the first front panel LED turns OFF.
The quantity of labels printed during this print quality test depends on
the dot density of the printhead.
n 300 dpi printers: 7 labels are printed at the 2 ips and 6 ips print
speeds.
n 200 dpi printers: 7 labels are printed at the 2 ips, 6 ips and 10 ips
print speeds.
Each label is printed at a different darkness setting, starting at three set-
tings below the currently configured value and continuing to increase
until it is three settings darker than the configured value. The relative
darkness and speed are printed on each label. The bar codes on these
labels can be ANSI-graded to check print quality.
