Printhead Pressure Adjustment
Toggle Pressure Adjustment

• After installing the Printhead correctly, lower
  the Printhead Assembly until it clicks into
  place.
• Once the Printhead Assembly is secure, run a
  print test.
• If the test label is too light on one side,
  increase the pressure (turning the toggle
  clockwise) on the lighter side using the pressure
  toggles until the print is consistent across the
  width of the label.

Too much pressure applied to the toggles will
shorten the life of the Printhead. Choose the
lowest pressure that produces the desired print
quality, maximizing Printhead life.
