5.6 Darkness Adjustment
The Darkness Adjustment (located on the rear of the printer), allows the
operator to adjust the ‘print darkness’ on the printed ticket. Turning the
Darkness Adjustment clockwise will make the print darker, turning it
counterclockwise will lighten the print.
Note: Large increases the ‘Darkness Adjustment’ can shorten
printhead life. If you need to increase the ‘Darkness’ level large
amounts, try instead increasing the Heat value and/or slowing
the Print Speed through your software or DPL commands first.
5.7 Resetting to the Factory Defaults
With the printer off, press and hold the F1, F2, and F3 buttons while
turning the printer on. 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 defaults.
