4.2 Adjusting the Printing Mechanism
Major adjustment of the printing mechanism beyond format-based settings is only required if the printhead assembly
has been removed or parts in this area have been replaced. Excluded from this is the replacement of the printhead,
after which readjustment is generally not required.
The following print quality imperfections may indicate maladjustment of the printing mechanism:
Print image too light
Print image is spotty
Print image lighter on one side
Horizontal lines not parallel to the horizontal label edges
Clear lateral drift of the transfer ribbon
i
Notice!
Print image errors can also arise from wrinkling of the transfer ribbon. This is why you should check the
transfer ribbon feed path and the head locking system for correct adjustment before making adjustments to
the printing mechanism  Operator's Manual.
Adjustment of the printing mechanism comprises the following procedures in the order specied:
Prepare the label printer for adjustment  4.2.1 on page 21.
Adjust the position of the printhead  4.2.2 on page 24.
Adjust the printhead pressure  4.2.3 on page 25.

Load labels and transfer ribbon which extend across
the entire printing width.

100 mm/s..
Move the transfer ribbon deection to the central
position (5) with the screw (4).
Position the plungers (2) in such a way that the
adjustment screws are accessible through the holes
(3) of the square axis.
Not at A2+ : Loosen the screw (1) for the printhead
bowing with an Allen key (1.5 mm) and turn it
