Adjust the Printhead
Printhead pressure and the darkness setting affect print quality. If the darkness setting is too
high for the labels and ribbon being used, it causes premature printhead wear. If the toggle
pressure is not even, labels and ribbon may slip.
Toggle adjustment may be needed if printing is too light on one side or if thick labels are used.
Make sure that the toggles are positioned properly.
The toggles should be positioned so they provide even pressure on the labels. The toggles are
positioned by sliding them to the desired location. If the labels are too narrow to fit both
toggles, position one toggle over the center of the labels and decrease the pressure on the
unused toggle.
If positioning the toggles properly does not solve the problem, adjust printhead pressure.
Printhead life can be maximized by using the lowest pressure that produces the desired print
quality.
To adjust printhead pressure, complete these steps:
1. Print some labels at 2.4 in. (61 mm) per second by running the PA U S E S e l f Te s t
on page 133.
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 locking nuts at the top of the toggle assemblies.
Important • Print quality depends on the labels and ribbon used as well as the toggle
pressure. Make sure your labels and ribbon are right for your application.
• Direct thermal labels do not need ribbon.
• Thermal transfer labels need thermal transfer ribbon.
Caution • Observe proper electrostatic safety precautions when handling any static-sensitive
components such as circuit boards and printheads.
