Pressure Adjustment
You may need to adjust the printhead pressure on the printer if:
• you are using thicker or thinner media than previously
• your labels are printing lighter on one side than the other
• your thermal transfer ribbon starts to crease
Do not use a higher printhead pressure than necessary. It may increase the wear on
the printhead and shorten its life.
1. Open the media cover.
2. Use a straight-screwdriver to adjust the pressure screw.
