Specifications

7. Adjustments are made in very small increments.
Turn both Parallelism Adjustment Screws one eighth turn clockwise and
observe the changes in print quality. (Due to spring pressure, there may be
a dead spot in the actual printhead movement when switching adjustments
from one direction to the other.)
8. Decrease the Burn Temperature until the PAUSE Test labels are a charcoal
gray color.
9. Carefully look at the PAUSE Test labels for streaks, flouring, and other
print quality problems.
10. If required, adjust the hex head screws and observe if print quality problems
are corrected.
11. Increase Burn Temperature until the PAUSE Test labels are printed at
optimum resolution and contrast.
12. Since Printhead parallelism, Wear Plate position, and Printhead position are
interrelated, carefully look at the test labels for changes in these settings
and adjust if necessary.
Printhead Pressure Adjustment
Printhead Pressure is the fourth of the four interrelated adjustments. Using lower
Printhead Pressure and Darkness settings can extend printhead life. If printing is
too light on one side or if a thick media is used, printhead pressure may require
adjustment.
Refer to Figure 5.4 for the location of the Pressure Toggle for the 105S and
105Se printers. This toggle should be positioned over the center of the media
width. The 160S printer has two toggles. These toggles are typically positioned
at the 1/4 and 3/4 positions across the width of the media. If narrow media is
used on the 160S, the inside toggle should be centered above the media and the
pressure of the outside toggle should be reduced to zero.
1. Print PAUSE Key Self Test labels to check print quality.
2. To increase printhead pressure, loosen the Upper Knurled Nut on the Toggle
and adjust the Lower Toggle Adjusting Nut downwards.
3. To decrease printhead pressure, loosen the Upper Knurled Nut and adjust
the Lower Toggle Adjusting Nut upwards.
4. Adjust printhead pressure for optimum print quality.
5. To lock-in printhead pressure, tighten the Upper Knurled Nut against the
Lower Toggle Adjusting Nut.
6. Though different media and ribbon combinations may require different
Toggle settings, a suggested initial distance between the bottom of the
Lower Toggle Adjusting Nut and the top of the black Toggle Button is
approximately 30 mm.
7. Adjust Burn Temperature to the optimum level for the installed media.
