If printing is light on
the right side of label,
turn the bias adjust screw
counterclockwise.

Use the darkness adjust control in combination with the Print Darkness
adjustment in PrintSet to fine-tune the darkness of print on the labels. The

printhead, or the printer. Set the darkness adjust control after you enter
the media sensitivity number.
