Adjusting Printhead Pressure

The pressure of the thermal printhead against the platen roller is
factory-adjusted. However, if the printing is weaker on one side
of the media, or if the thermal transfer ribbon starts to crease
(indicated by unprinted white streaks along the media feed
direction), it may be necessary to readjust the printhead pressure.
Note: Before readjusting the printhead pressure, try to move the
outer balance box as described in the previous Adjusting
Printhead Balance procedure.
To adjust printhead pressure
1 Open the side door.
2 Remove the ribbon.
3 Lift the printhead by pulling the printhead lever out and
flipping it a quarter of a turn counterclockwise.
4 Use a straight-slot screwdriver to turn the screw at the top of
the balance boxes clockwise to increase the pressure, or
counterclockwise to decrease the pressure.
5 Engage the printhead and load the ribbon.
6 Test and readjust if necessary. (Tip: Use direct thermal media
to avoid loading and unloading of ribbon multiple times.)

Adjusting Printhead Dot Line

When using thick or stiff media, the printhead needs to be
moved forward so the dot line is aligned precisely with the top of
the platen roller. It is also important to ensure that the printhead
dot line and the platen roller are parallel.
