5.6Darkness Adjustment
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.
;Note: 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.
5.7 Resetting to the Factory Defaults

STOP light turns off (approximately 17 seconds). The printer will now be set to the ‘Factory Defaults.’ See Section 4.5.1 for a listing of the factory default settings. Resetting to ‘Factory Defaults’ will not effect the following settings:
5) | SOP ADJUST | 12) | TOF GAIN |
6) | PRESENT ADJUST | 13) | TOF DELTA |
