6.8 Adjusting the transfer ribbon feed path
*
Adjust the transfer ribbon feed path by changing the head contact
pressure and adjusting the transfer ribbon deflection. Increasing the
head contact pressure with the screws (3a) and (3b) shifts the ribbon
feed path in the corresponding direction. The skew of the transfer
ribbon deflection is used to suppress wrinkles in the transfer ribbon
feed path. Wrinkles which cannot be remedied with the skew of the
transfer ribbon deflection can be suppressed by bowing the printhead.
CAUTION!
The printhead assembly can be damaged when bowing the
printhead.
Turning the adjustment screw (1) too hard can cause
damage to the printhead assembly.

As soon as a clear resistance is perceived when
turning the adjustment screw (1), only continue turning
the screw in very small increments, but no more than
one eighth of a turn.

Only turn the adjustment screw (1) as far as is
absolutely necessary.
Figure 23
1. Check the transfer ribbon feed path.
The wound up ribbon should be the same
distance from the disk of the winder as the
supply roll is from the disk of the rewinder.
2. If the ribbon runs inward or outward, turn the
corresponding screw (3a) or (3b) clockwise in
small increments.
3. Wait until the ribbon feed path has stabilized
after each step of the adjustment.
4. Check the ribbon feed path for wrinkles.
5. If wrinkles arise on the inside, turn the screw (2)
counter clockwise.
6. If wrinkles arise on the outside, turn the screw
(2) clockwise.
7. If the wrinkles cannot be remedied (e.g. wrinkles
in the centre), turn the adjustment screw (1)
clockwise with extreme care (see warnings)
using a hexagonal wrench (1.5 mm) and
observe the ribbon feed path.
When the adjustment screw (1) is tightened, the
printhead is bent downward slightly in the
centre. It is possible that a slight lightening at
the edge areas of the print image could occur
here.
8. If bowing is not necessary, turn the screw (2)
clockwise until the screw is just barely clamping.
