Printhead Pressure Adjustment
This adjustment may be necessary if printing is too light on one side or if
thick media is used. Refer to Figure 14.
1. Perform the Toggle Positioning procedure above. If the problem is
solved, you may stop here; otherwise, continue with the rest of this
procedure.
2. Print some labels at Speed A, such as by running the Pause Key Self
Test (see page 67).
3. While printing labels, lower the Darkness setting until a gray level
of printing is seen.
4. Loosen the knurled (upper) locking nuts at the top of the toggle
assembly/assemblies.
5. Increase or decrease spring pressure (using the knurled adjustment
nuts on the shafts of the toggles) until the left and right edges of
printed area are equally dark.
NOTE: Printhead life can be maximized by using the lowest pressure
that produces the desired print quality.
6. Increase Darkness to optimum level for the media being used.
7. Retighten locking nuts.
