The sketch (see Figure 22) shows from behind the shaft of ribbon
save motor (H) with pressure curve (C) and disc (B). The bearing ring
(D) with the attached sole plate (E) is underneath.
3. Make sure that the printhead is closed.
4. Loosen the hex socket head screw (F) about 1 turn until the sole
plate (E) with the attached ball bearing is freely mobile.
5. Turn by hand the motor shaft with pressure curve and disk in the
adjusting position.
6. Press the sole plate (E) with the ball bearing (G) in the adjusting
notch of the pressure curve. Take care of not to have too much
play. Fasten the hex socket head screw (F).
7. Lift up the printhead.
8. Turn by hand the motor shaft with pressure curve and disc into the
adjusting position.
9. Move down the printhead.
10. Turn by hand the motor shaft with pressure curve and disk from
the lift to the right until a slight resistance can be noticed. If the
slot in the disk can be moved slightly to the right and to the left out
of the photocell (A), then the pressure curve is adjusted correctly.
11. If the gap should not be in the range of the photocell, the following
causes are possible:

The wrong notch on the pressure curve was used for the
adjustment.

The pressure curve is twisted to the disc on the motor shaft.
The slot of disc has to be placed exactly face to face with
the printer position notch!
12. Connect the protective conductor to the inside of printer cover.
13. Move the printer cover onto the chassis.
14. Switch on the printer.
15. Press the keys and to move the printhead down and up. If
very thick label material is used it could occur that the printhead is
not enough lifted up. In order to position the printhead correctly,
repeat the adjusting steps again. However, keep the material
during the adjustment between the printhead and the roller.
16. Install again the printer cover.
