Figure 9. Thermal Head Positioning - AMT Datasouth CodeWriter 5106 Technical Reference

NOTE:
Too much lifting up of the thermal head will result in too light (weak) of a contrast in
printing. Adjusting the head pressure thumb screw will have a direct effect on the
contrast, ribbon feeding, and form feeding.
13. If the right part of the contrast of Result 3 is better than others, move Bracket EA
to the rear slightly by loosening the one phillips screw. When the right part of the
contrast of Result 2 is better than others, move Bracket EA to the front slightly by
loosening two phillips screws. If the ribbon applicator interferes with the thermal
head, move it forward
NOTE:
The thermal head and Bracket EA are fixed so that the parts rotate around the shaft as
indicated in Figure 10. Therefore, when you push the thermal head block down, the
relative position between the heat line of the thermal head and the center of the platen
roller becomes narrower. This is similar to moving the thermal head toward the front.
When lifting the thermal head block up, the relative position between the heat line of the
thermal head and the center of the platen roller becomes wider. This is similar to moving
the thermal head to the rear.
