If after the above adjustments have been made, you find yourself continuing to experience problems, try the following:
1.Push back the thermal head lever in order to release the thermal head block from the platen roller.
2.Loose the two phillips screws which fix Bracket EA, which supports the thermal head, to Bracket AA.
3.Set Bracket EA to the front edge of Bracket AA. Tighten the two phillips screws temporarily. Pull up the thermal head lever.
4.Check for a .787” distance from the upper surface of the aluminum plate of the thermal head to the upper surface of Bracket AA at the right side of the thermal head block. If it is not .787”, continue to the next step. If the distance is .787”, go to Step 8.
5.Push down the thermal head lever again. Loosen the left screw as shown in Figure 7.
