Adjusting the Printhead Pressure

Adjusting the Printhead Pressure

If positioning the toggles properly does not solve a print quality or other issue, try adjusting the printhead pressure. Maximize printhead life by using the lowest pressure that produces the desired print quality.
Perform this procedure if you are experiencing any of the following:
  • The media requires higher pressure overall to print well.
  • The media requires lower pressure overall to print well.
  • The prints is too light on the left side of the label.
  • The print is too light on the right side of the label.
  • The media shifts left while printing.
  • The media shifts right while printing.
If none of these issues exist, do not continue with this procedure.
  1. Equally space the toggles across the width of the media.
  2. Measure the distance from the top of the toggle foot (1) to the bottom of the lower knurled nut (2). If the measurement is not 1-3/16 in. (30 mm), loosen the upper knurled nut (3) and adjust the lower knurled nut until the distance is correct.
  3. Initiate the PRINT LINE option of PRINT TEST FORMAT.
  4. While printing labels, use the control panel to lower the darkness setting until the labels are printing gray instead of black. (See DARKNESS.)
  5. Which of the following issues are you experiencing?
    If the media...
    Then...
    Requires higher pressure overall to print well.
    Increase the pressure on both toggles.
    Requires lower pressure overall to print well.
    Decrease the pressure on both toggles.
    Prints too lightly on the left side of the label.
    Increase the pressure on the inside toggle.
    Prints too lightly on the right side of the label.
    Increase the pressure on the outside toggle.
    Shifts left while printing.
    Increase the pressure on the outside toggle.
    OR
    Decrease the pressure on the inside toggle.
    Shifts right while printing.
    Increase the pressure on the inside toggle.
    OR
    Decrease the pressure on the outside toggle
  6. Lock the toggle pressure by tightening the upper knurled nut against the lower knurled nut.
  7. Reposition the toggles for printing.
  8. If necessary, reinitiate the PRINT LINE option of PRINT TEST FORMAT.
  9. While printing labels, use the control panel to raise the darkness setting until the labels are again printing black instead of gray. (See DARKNESS.)
  10. Check the print quality, and if necessary, repeat this procedure until the printhead pressure is adequate.
