Non-display printers: The Darkness Adjustment allows the operator to match the print contrast
following a printhead replacement. Turning the Darkness Adjustment clockwise will darken the
print, while turning it counterclockwise will lighten the print. Compare a label printed with the old
printhead and make this adjustment so that the new printhead matches the darkest portion of
that label.
Display-equipped printers: Use the printer’s menu to adjust Darkness; see Section 4.5, Print
Control / Custom Adjustments.

Darkness Adjustment

Large increases in the ‘Darkness Adjustment’ can shorten printhead life. If you need to
increase the darkness of the printed labels, try increasing the Heat value and/or slow the Print
Speed using your software program or via DPL commands
