Adjusting the Print Mechanism

Changing the settings of the printing mechanic over and above a format change is only necessary when something
other than the printhead is exchanged or if the printhead assembly group has been demounted or altered.
The following identifiers point towards resetting the printing mechanic:
- Printed image too light
- Printed image blotchy or spotty
- Printed image too light on one side
- Horizontal lines not parallel to the to the label edge
- Clear sideways drift of the ribbon
i
Note!
Check the ribbon as creases in it may cause image errors.

Adjustable Elements

Fig. 16 Adjustable elements
Screws for horizontal settings (1)
- Turning the screw clockwise will move the printhead forward.
- Turning the screw counter clockwise will move the printhead backwards.
For an optimal image the heat element must be set to align to the highest point of the pressure roller. In this position
the print image blackening is at its best. Besides that this setting allows the realignment of horizontal lines with the
dispensing edge.
Screws for setting the printhead (6)
- Turning of the screws in a clockwise fashion lessens the printhead pressure to the corresponding side.
- Turning the screws counter clockwise increase the pressure.
Increasing the pressure of the print by turning screw (6) counter clockwise will darken the image on the corre-
sponding side and shift the ribbon flow toward the opposite side.
!
Attention!
Turn the screw (6) counter clockwise carefully as an excess will demount parts completely.
