FEED Key Self Test

Press and hold the FEED key while turning the print engine power ON. Release the key

anytime after the first front panel LED turns OFF.

NOTE: The CANCEL Key Self Test should be performed prior to this self test. Infor-

mation on the printed configuration label can be used with the results of this self test

to determine the best darkness setting for a specific media/ribbon combination.

The labels printed during this print quality test depends on the dot density of the print-

head.

• 300 dpi print engines: 7 labels are printed at the 2 ips and 8 ips print speeds.

• 200 dpi print engines: 7 labels are printed at the 2 ips and 12 ips print speeds.

Each label is printed at a different darkness setting, starting at three settings 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.

Compare these labels to determine which has the best print quality. Then add or subtract

the value printed on that label from the darkness value specified on the configuration

label. The resulting numeric value (0 to 30) is the best darkness value for that specific

media/ribbon combination. Use the front panel configuration process to set the Print

Darkness parameter to the new value. Refer to Figure 15 for an example of the label.
