Adjust Printhead Pressure and Toggle Position
Printhead Pressure Adjustment
If positioning the toggles properly does not solve the problem, adjust printhead pressure. Maximize printhead life by using the lowest pressure that produces the desired print quality.
Caution • Observe proper electrostatic safety precautions when handling any static- sensitive components such as circuit boards and printheads.
To adjust printhead pressure, complete these steps:
1.Print some labels at 2.4 in. (61 mm) per second by running the PAUSE Self Test on page 137.
2.While printing labels, use the front panel controls to lower the darkness setting until the labels are printing gray instead of black.
3.Loosen the upper knurled nuts on the toggle assemblies (Figure 31).

4.Some media types require higher pressure to print well. For these media types, increase or decrease pressure using the lower knurled nuts until the left and right edges of the printed area are equally dark.
5.Increase the darkness level using the front panel controls until the printing is clear.
6.Tighten the upper knurled nuts.
