Chapter 24 Print Quality Adjustment
Factory-made Adjustments
The platen roller and the liner drive roller can be adjusted, so
they become perpendicular to the inner gable of the print unit, by
moving the lower, outer gable. The gable is held by four #T20
Torx screws. Three of the screws hold the gable to the extruded alu-
minium profi le that connects the inner and outer gables, whereas
the fourth, center screw holds a dovetail-shaped plate that fi ts into
a channel in the profi le (see Chapter 8.2).
As long as the center screw is not loosened, the outer gable can be
removed and put back without the adjustment being lost. Readjust-
ment requires a fi xture and should not be attempted without such
a device.
The printhead bracket is factory-adjusted in relation to the headlift
shaft by means of oversized holes for the three screws that hold the
two parts together (see Chapter 8.8). Adjustment requires a special
fi xture and should not be otherwise attempted.

CAUTION!
The ribbon save print unit has no
provision for retaining the platen roller

removed, see Chapter 10.6.
