5.Push both wires and thermal head back to original position on bracket EA. Bracket EA has two locations on its underside to locate the head position correctly (see Figure 9, page 17).
6.While holding thermal head at its original position, tighten two hexagon bolts temporarily. Then fix thermal head to bracket EA.
Note:
Incorrect position of thermal head on bracket EA will cause the ribbon to wrinkle or cause uneven contrast when printing on media (labels).
