Darkness Adjustment; Resetting To The Factory Defaults - Datamax M-Class Mark II M-4206 Operator's Manual

5.6 Darkness 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.

With the printer power 'Off,' press and hold all three buttons while turning 'On' the printer. Continue to hold the buttons
down until the light turns off (approximately 17 seconds). The printer will now be set to the 'Factory Defaults.'
