5.6Darkness Adjustment
The Darkness Adjustment (located on the rear of the printer) 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.
;Note: Large increases in the ‘Darkness Adjustment’ can shorten printhead life. If you need to increase the darkness of the printed labels, increase the Heat value and/or slow the Print Speed using your software program or via DPL commands.

With the printer power ‘Off,’ press and hold the F1, F2, and F3 buttons while turning ‘On’ the printer. Continue to hold the buttons down until the PAUSED Light turns off. The printer will now be set to the ‘Factory Defaults.’ See Section 4.4.1 for a listing of the factory default settings.
